The DDS 5900 Digital Discussion System is a conferencing solution with plug-and-play setup and online discussion management. With excellent audio quality and programmable touch-button controls, compact microphone units facilitate clear communication in large groups and meeting spaces. The system manages up to eight talkers at a time and dedicates two channels for interpretation, supporting bilingual events without additional equipment.
The DDS 5900 Digital Discussion System is comprised of one central unit, the control browser, and discussion units for up to 250 participants. Supporting multiple user types, a gooseneck microphone, loudspeaker, and control buttons are combined in a compact discussion unit. With highly flexible layout options and a choice of tabletop or flushmount units, the system seamlessly integrates into a wide range of professional environments, such as:
| Clear, Natural Communication | DDS 5900 discussion units enhance group communication, allowing natural conversation to be heard in large meeting spaces. Gooseneck microphones provide excellent speech isolation, while the LED light ring indicates who is talking. A 24-bit digital audio signal is transported to each discussion unit for real-time monitoring from the loudspeaker. Several microphone operation modes provide manual and automatic microphone activations. |
| Sleek, Professional Design | Modern, low-profile design integrates into a variety of spaces, from historic buildings to contemporary boardrooms. DDS 5900 discussion units are intuitive and functional, reducing clutter and increasing tabletop workspace. Two model variations are available to support the needs of any event:
|
| Flexible Setup and Easy Installation | The DDS 5900 system uses a proprietary protocol to transport digital audio, control data, and power over the same cable (shielded Cat5e). The system supports large events of up to 250 participants, easily scaling with additional components added inline for a simplified layout topology. |
| Remote Management | For comprehensive system management, open the browser-based control app using a computer or tablet. The interface adds system configuration and discussion setup capabilities, enabling an administrator to prepare the discussion with participant names and seat numbers. The chairman or moderator uses a dedicated page for speaker management during the discussion. The system is also compatible with Crestron, AMX, and other control systems. The CCU easily interconnects with teleconferencing equipment and external audio components. |
The DDS 5900 Discussion system is an important communication tool for meetings of any size. Participants use the discussion unit microphone and loudspeaker to communicate using natural speech levels.
The DDS 5900 Discussion System improves communication amongst a group of people by combining the microphone, loudspeaker, interpretation audio, and user controls in an integrated unit. When a participant speaks, their voice is heard at the other units' loudspeakers. The DDS 5900 is a perfect solution when every participant is both a talker and a listener.
In contrast, traditional sound systems support the communication of one or two speakers to a crowd of people. In those systems, it is impossible to have the dialog required in a discussion setting.
The DDS 5900 discussion unit is programmable to support different functions required by different people involved in the discussion. For example, as the moderator of the discussion, the chairman has an extra control that immediately turns off all delegate microphones. In a typical event, there are three categories of participants:
The following is an overview of each participant role and how they function in a typical discussion.
| Delegate (member, participant) | The majority of participants fall into this category. The delegate role is for anyone involved in the discussion that is not a chairman or interpreter. Delegates use the discussion unit to speak and listen to other participants. Depending on the discussion settings, the delegate may send a request to speak before the microphone is activated by the Chair.
|
| Chairman (chair, moderator, president) | The chairman, or simply the Chair, is the moderator of the discussion. Typically seated at the head of the meeting space, the Chair has the ultimate authority over who is speaking. Using the browser interface, the moderator has ability to turn microphones on or off for specific participants, and view the order in which participants request to speak. Providing immediate control of the discussion, an 'all-delegates off' button is available on discussion units programmed to chairman mode.
|
| Interpreter | When an additional language is spoken in a discussion, an interpreter provides simultaneous interpretation using the discussion unit. Interpreters select from one of two channels to transmit to other participants speaking the same language. This system supports bilingual, two-way discussion, facilitating the back-and-forth communication between delegates speaking two different languages.
|
The DDS 5900 Discussion System consists of the following components:
| ① DIS-CCU Central Control Unit | The central control unit (CCU) is the processor for the DDS 5900 system. It provides power and control to the discussion units, analog audio inputs and outputs for external equipment, and a web server that hosts the browser interface for remote system control. Each system uses a single CCU. | ||||
| ② Discussion Units | Participants use the discussion units (DU) to speak and listen to other members of the event. A microphone, loudspeaker, and channel selector are provided for each unit. Units connect in series, simplifying setup by transporting power, audio, and control data on the same cable. There are two models of discussion units:
|
||||
| ③ Browser Interface | The browser interface provides comprehensive setup and discussion management for the DDS 5900 system. It opens in a web browser from a computer networked with the CCU. Use the interface to manage microphones, assign names and seat numbers to delegates, and advanced system configuration. |
The DIS-CCU Central Unit provides the intelligence for systems of up to 250 participants in the DDS 5900 system. It processes audio and control signals from each discussion and interpreter unit, and distributes audio to other participants for listening to the discussion.

Microphone units operate by connecting in series from the central unit. Power, audio, and data are transported over a shielded Cat 5e cable from one unit to the next. This topology enables flexible and inexpensive installation for large groups of people.
Install the central control unit in a standard 19” rack using the supplied 19” brackets. Remove the screws holding the top and bottom covers, then attach the brackets to the front of the unit using the same screws.
Important: Use the two 10 mm length self-threading screws closest to the front and the 8 mm length threaded screw furthest from the front.
The built-in fan draws air in on the left side and exhausts air on the right, and so does not require extra space above or below for cooling.
Shure offers cables designed specifically for the DIS line of conferencing and discussion equipment. The Shure EC 6001 are high-quality Ethernet cables available various lengths from 0.5 m to 100 m. Each cable has been tested to ensure reliable system performance. See the accessories section for ordering information on the EC 6001-xx.
Important: Cables and connectors must be shielded for stable system performance. If an installation does not use Shure EC 6001 cables, they must follow the Cat5e cable requirements.
| Type | Cat5e (or higher) twisted pair |
| Shielding | F/UTP or U/FTP |
| Connector | Shielded RJ45 |
| Weight | AWG 24 |
| Maximum Cable Length |
|
Important: Cables and connectors must be shielded for stable system performance. If an installation does not use Shure EC 6001 cables, they must follow the Cat5e cable requirements.
When designing a system with a patch panel, crimp the cable to the female shielded connector on the panel. Then simply use short jumper cables to connect to the conference units.
Microphone units and DCS-LAN components are connected in sequence (daisy-chain) using the two RJ45 ports on each unit. The connectors are interchangeable; simply connect the previous unit to one port, and the following unit to the other port. Always use shielded Cat5e (or higher) cabling for reliable system performance.
Power, control data, and audio are transported from one unit to the next over the same shielded Cat5e cable.
To protect the equipment, ensure that the central control unit (CCU) is always off when connecting or disconnecting the microphone units. Use any of the four chain outputs (A, B, C, and/or D) for connecting DCS-LAN components.
Note: Do not turn off CCU power until the system has stabilized
The following system diagrams illustrate typical hardware connections to the DIS-CCU central control unit. Actual installations may use different combinations of hardware, but follow the general concepts outlined below.
Note: Flushmount and portable discussion units are interchangeable in the following drawings, unless noted.
The system is operational without the use of a computer. Use the CCU navigation screen to set up the installation.
Note: This setup does not support the Manual microphone mode, since the browser interface is required for turning microphones on and off.
Basic System with Multiple Chains
Connect a computer to the central control unit for comprehensive management of the system through a web browser. Connect an Ethernet cable from the dedicated TCP/IP port to a computer.
Computer Control
Use a wireless router to access the web browser from a laptop or tablet. The web browser on a mobile device offers the same comprehensive system management.
Wireless Control
The DDS 5900 Discussion System supports bilingual discussion, routing an interpretation channel to each discussion unit. Program the DC 5980 P portable discussion unit for use as an interpretation station. Other participants use the headphone jack on their unit to listen to the interpretation channel of their choice.
Typically, a separate room or booth is dedicated for interpreters for greater sound isolation. Units can connect in any order in the DCS-LAN chain, irrespective of operation mode of the adjacent unit.
Interpretation Units
Connect an audio recorder to the analog outputs of the CCU to record floor audio, translations, or a specific set of microphones. Use the browser interface to buss units to groups and assign them to the specific output (A-H). Connect the XLR outputs of the CCU to the inputs of an audio recorder.
Recording Audio
Connect a mixer to the CCU analog outputs to control individual microphone volume or equalization. Use the browser interface to buss units to groups and assign them to the specific output (A-H).
To return the audio to the DDS 5900 system:
Inserting a Mixer or DSP
For additional monitoring, connect a wireless language distribution system to one of the CCU audio outputs. Use the browser interface to select the desired microphones (seat) for that group output (A-H). The DCS 6000 Digital Infrared Language System transmits this audio signal to a number of listening stations.
Wireless Language Distribution
Input 2 is designed to broadcast an Emergency Evacuation Message (EEM), overriding the discussion in the event of an emergency. A switch (normally-open) must be connected to the emergency switch connector. When the switch is closed an "Emergency Evacuation Message (EEM)" audio signal present on the 'In 2' input is distributed to all output channels, overriding all other audio inputs.
For most installations, the DIS-CCU supplies sufficient power for the discussion units. Depending on the setup, the CCU powers up to 50 units at a time without additional equipment. The number of supported discussion units depends on the size and layout of the installation.
Note: maximum cable length in one chain is 120 m before a repeater unit.
Power Depends on Installation Variables
To maximize the unit count without adding equipment:
The following tables show how to connect the most discussion units without adding additional equipment.
Note: When using multiple chains, distribute the number of units evenly across the chains to maximize unit count.
| Cable length from CCU to the first unit | Estimated Number of Discussion Units Powered from CCU | |||
|---|---|---|---|---|
| One Chain | Two Chains | Three chains | Four chains | |
| 10 m | 43 | 47 | 48 | 48 |
| 30 m | 39 | 45 | 47 | 48 |
| 50 m | 36 | 43 | 45 | 46 |
| 100 m | 21 | 38 | 42 | 44 |
| Cable length from CCU to the first unit | Estimated Number of Discussion Units Powered from CCU | |||
|---|---|---|---|---|
| One Chain | Two Chains | Three chains | Four chains | |

| 30 m | 37 | 44 | 46 | 48 |
| 50 m | 34 | 42 | 45 | 46 |
| 100 m | 11 | 22 | 33 | 43 |
Note: Power requirements for the DC 5900 F discussion unit vary depending on the configuration of the unit. Additional discussion units are supported when the loudspeaker is removed and when GM gooseneck microphones are used instead of the MX4xx series microphones.
The JB 6104 junction box adds four additional outputs to a point on the DCS-LAN chain. These four outputs are available for short-run connections to DUs, protecting the DCS-LAN chain from technical failures or hot-plugging damage. A single DU can connect to each JB output, with a maximum cable length of 10 m.
| Cable length from CCU to the first unit | Cable Length Between each JB 6104 | Number of JB 6104 | Maximum Number of DUs |
|---|---|---|---|
| 10 m | 3 m | 19 | 37 |
| 30 m | 3 m | 17 | 34 |
| 50 m | 3 m | 15 | 30 |
| 100 m | 3 m | 7 | 14 |
| Cable length from CCU to the first unit | Cable Length Between each JB 6104 | Number of JB 6104 | Maximum Number of DUs |

| Cable length from CCU to the first unit | Cable Length Between each JB 6104 | Number of JB 6104 | Maximum Number of DUs |
|---|---|---|---|
| 10 m | 5 m | 13 | 50 |
| 30 m | 5 m | 12 | 48 |
| 50 m | 5 m | 12 | 46 |
| 100 m | 5 m | 10 | 40 |
Follow these guidelines for the most reliable installation.
Shielding must be consistent through the DCS-LAN chain. Any cable or patch panel used for DIS components requires shielded RJ45 connectors. All DIS components feature shielded RJ45 female connectors.
Avoid accidentally grounding the DCS-LAN signal with the chassis ground of a patch panel. The DCS-LAN uses the shield as a signal ground reference and cannot contact another ground anywhere in the connection.
Avoid Grounding in a Patch Panel
To avoid ground issues:
Note: The female connectors in all DIS components units feature an air gap that isolates the chassis of the connector and the chassis of the unit preventing any galvanic (physical and thus electrical) connection.
As with any cable carrying a signal, use care when installing the equipment.
Bending Rule
Do not sharply bend the cable. Ethernet cables cannot bend more than four-times the diameter of the cable.
Pinching
Do not over-fasten the cable. A pinched cable may not operate correctly.
Attach the touch-button overlay to each unit for basic microphone control. The discussion units use soft buttons that change functionality when programmed to different unit types. Button overlays are supplied with the discussion unit or with the central unit.
Warning: Overlays are not reusable. If a unit needs to be reconfigured, carefully remove the overlay and apply another one.
To lock the microphone into place, use the supplied hex key and turn counterclockwise.
DIS GM: Simply insert the microphone into the XLR socket. Adjust the gooseneck for proper position.
Shure MX4xxRLP: Attach the AC 5901 XLR/Microflex adapter to the microphone. Insert the adapter into the XLR socket of the flushmount unit.
DDS 5900 discussion units are programmable, changing the function of the control buttons to support different user types. The three types are chairman, delegate, or interpreter, each requiring unique control functionality. The setting is stored in the unit, and persists after a power cycle.
Note: Flushmount units are not programmable as interpreter stations. Use the portable DC 5980 P unit for simultaneous interpretation.
To program the flushmount DC 5900 F discussion unit as a chairman or delegate, simply attach the button overlay. The overlay automatically programs the unit with the correct button functionality.
Reboot the system once all the overlays are attached to establish the configurations with the CU.
Program the portable units by pressing the volume buttons and scrolling to the desired mode.
| Unit Type | Ch. 1 | Ch. 2 |
|---|---|---|
| Delegate with mute | Off | Off |
| Delegate without mute | On | Off |
| Chairman | Off | On |
| Interpreter | On | On |
For comprehensive management and remote control of the system, open the web interface on a computer or tablet. The central control unit (DIS-CCU) provides a web server for system control from a web browser on a networked computer. The web app offers advanced parameters for setting up the system, and enables the chairman or moderator to manage microphones using participant names and seat numbers.
Note: The computer network is separate from the component network (DCS-LAN).
DDS 5900 Web Interface
System Requirements
For best performance, always update the browser to the latest released version. The following browsers function properly with the system interface:
Follow these instructions to open the browser interface on a computer.
Connect to the CCU
Access to the system interface is available from two network addresses: IP address and hostname. Typing either address into a browser will access the interface of the connected CU.
Manage the network address from the browser:
Select 'Dynamic' if the CCU is connected to a network with a DHCP server. Otherwise select 'Static' and assign a fixed IP address to the CU. Default IP configuration is "Dynamic".
Select 'Apply Changes' to save the changes made.
View the IP address from the CCU front panel:
.
The hostname is a user-defined name that can be assigned to the device to access the browser instead of using the IP address. The hostname is titled in a logical manner to easily identify the component on the network. More importantly, the hostname will not change on its own (unlike the IP setting), making it ideal for bookmarking.
For example, if the system is set up in the primary meeting room, the hostname could be called, "MainRoom" resulting in the address: http://mainroom.local.
The system and browser interface are supported in a variety of languages. Go to to select the desired language.

In addition to the administrator access to the web interface, there are two separate addresses useful to the participants during the meeting:
By default, anyone can access these views from a computer or mobile device connected to the network. To protect these pages, the administrator can assign a password to each from the Security page.
This page is dedicated for microphone control during the meeting. Use this view as a chairperson or meeting operator to manage speakers, speak requests, and replies.
For access, enter the IP address of the CCU, followed by /chairman (example: http://172.17.11.137/chairman).
The display page is used to provide the meeting participants with a view of the speaker, speak request, and reply lists.
For access, enter the IP address of the CCU, followed by /display (example: http://172.17.11.137/display).
Tip: Put the page in full-screen mode during the meeting:
DIS components use a proprietary codec algorithm to prevent unauthorized devices from listening to the audio signal. To further protect the discussion, assign a password to the browser interface and enable security features on wireless routers.
You can assign a password to restrict access to the browser interface. An independent password is assignable to each of the three interface addresses: administrator, chairman, and display.
Note: passwords are cleared when the unit is reset to factory default settings.
To clear the password access to the CCU, restore factory default settings.
Note: Resetting to factory defaults will erase all delegate, system, and IP settings.

For maximum security, isolate the control network with a dedicated computer or a protected router.
When the discussion begins, the chairman or discussion moderator will need to refer to the participants by either name, seat number, or both. The proper assignment of names and seat numbers is critical to ensure the continuity of the discussion.
When logging in with the browser interface to an installation for the first time, each microphone unit appears with its default name. Units are automatically assigned a seat number. Chairman units also appear in the participant setup page. Use the participant setup page to match the units to the anticipated seating chart.
Reassign Seat Numbers
Add Participant names
When a microphone is turned on, the audio is routed to the main mix (Group A) by default. This mix is often referred to as the floor mix because it transmits the audio from anyone participating in the meeting. Interpreters also listen to the floor to provide language interpretation for multilingual discussions.
By default, the floor mix is routed to the loudspeaker and headphone output (Channel 0) of each connected microphone unit.
Go to the Group Setup page to view or modify the microphone routing.
For each microphone, select one of the following options:
Loudspeakers are included in most microphone units for localized sound-reinforcement of the discussion. When a participant uses their microphone, their speech is heard at other unit loudspeakers. This improves speech clarity in large rooms and reduces typical problems associated with sound reinforcement systems.
A Loudspeaker for Each Participant
Each participant can listen to the discussion on a personal loudspeaker attached to the microphone unit.
Note: To avoid feedback, the loudspeaker is turned off when that microphone is active.
Loudspeaker volume is a system setting that applies to all connected units. Volume is adjustable from -0 dB (no attenuation) to -40 dB, including off (mute). To adjust the volume:
| From the Browser Interface | Go to the Loudspeaker Control page () |
| From the CU | Scroll to the Loudspeaker Menu () |
Most microphone units include a headphone output for listening to interpreter channels or other participants on the floor channel. Each participant chooses their channel from the microphone unit channel selectors.
Channels 1 and 2 are dedicated for language interpretation. Participants select one of the channels to listen to their language during a bilingual event. The audio source comes from interpreter stations transmitting onto their selected channel.
Channel 0 (the floor channel) is used by interpreters to provide simultaneous interpretation of the discussion. This channel is also selectable by other participants to listen to the floor channel on headphones (channel 0 = LEDs off).
Use Headphones for Language Interpretation
By default all microphones are routed to loudspeaker and headphone mixes.
To change the audio source:
Eight analog outputs are available for recording, language distribution system, teleconferencing unit, or an external PA system.
Eight Analog Outputs
Go to and choose from the following options:
Note: If the group buss is not used for the corresponding XLR output, it is unavailable in the routing matrix.
Two inputs are available on the DIS-CCU for adding an external audio source to the system, often useful for teleconferencing or internet calling.
Input Control Page
To prepare for an emergency, connect an Emergency Evacuation Message (EEM) audio signal to Input 2. The block connector provides a 'normally-open' switch that when closed, distributes the emergency signal to the loudspeakers and all input and output connections.
Important: When the switch is used for Input 2, the EEM audio signal bypasses the volume and on/off settings. Control the volume of the EEM signal at the source output.
The operation mode determines how participant microphones function during a meeting. Several factors may affect the meeting requirements and the manner in which the meeting is run: room size, number of participants, formality of the event, and amount of technical support on staff. The operation mode addresses these factors with four presets to control the microphone behavior.
To change the mode:
| Description of Operation Modes | The following is a description of each mode once the Speak button is pressed: |
|---|---|
| Auto (Automatic) | Automatically turns on the participant microphone if there is room in the speaker list. In this mode, there is no request queue: if the Speaker List is full, the participant microphone does not turn on. |
| Manual | Adds the participant to a request queue that is managed by the chairman. The Chairman selects participant microphones from the queue list, and turns them on and off. Manual is the only mode in which the web browser is required to manage talkers. |
| FIFO (First In, First Out) | Automatically turns on the participant microphone if there is room in the speaker list. Once the list is full, participants are placed into a chronological request queue. The microphone turns on automatically once a space is open in the speaker list. |
| VOX (Voice Activation) | The microphone automatically turns on when a participant talks into the microphone or presses the Speak button. The microphone automatically turns off after the talker is finished. In this mode, there is no request queue: if the Speaker List is full, the participant microphone does not turn on. |
This mode determines the behavior of the microphone units when the speaker list is full:
Speaker List with a Maximum of 3 Speakers
When Speak Interrupt is on, a participant that turns on their microphone will override the last person in the speaker list.
DDS 5900 discussion units are programmable during setup to support the role of each member of a meeting.
As the leader of the event, the chairman has several unique features enabled on the discussion unit.
Delegate units contribute to the main audio mix called the floor mix. The number of simultaneous delegate speakers is limited, requiring different control buttons to participate in the discussion:
Red = microphone is on
Green = microphone is in the request queue
The primary function of the interpreter unit is to translate the discussion into a foreign language. Participants that do not speak the native language of the discussion rely on the interpreter to participate. Interpretors listen to the floor sound
Interpretation stations can only be assigned to the Portable 5980 P discussion unit.
Make additional adjustments to the unit speak button from .
Speak Button Lock prevents conflicts that can occur when two people attempt to perform the same action on a unit. The lock temporarily disables the speak button, preventing a participant from overriding an action set by the operator and accidentally turning off their own microphone. Assign a lock duration between 1 - 120 seconds.
Tip: To override the lock, press and hold the speak button for the duration assigned to the Lock Override Time (1 – 120 seconds).
Allow or prevent participants from turning off their microphones using the speak button on the unit:
To improve speaker management and clarity of the audio, there is a limit to the number of speakers at the same time. Up to eight chairman and delegate microphones can be open at once. There are several settings:
Note: Interpreter units are always active and do not impact the speaker list.
| Max speakers |
|
| Maximum Requests | Total number of participants that can be in the request queue at one time. |
Set the total number of speakers to one (1) higher than the maximum number of participants. If there are two chairmen, set the number to two (2) higher.
First In, First Out (FIFO) mode automatically turns on microphones based on a chronological queue list. This mode works best if the maximum number of participants is set to one (1), so that the participant must wait to speak until the other is finished.
In VOX mode, the microphone activates automatically once a participant speaks. The mode is ideal for meetings that are more conversational, allowing back-and-forth communication that doesn't involve speak requests and button activation. The following settings allow VOX to be customized for the meeting:
| Voice Detection Threshold | Determines the input level (dB) that activates the microphone. Lower settings activate the microphone with a quieter source, while higher settings require a louder source to activate the microphone.
|
||||||
| Release Time | Determines how long a microphone remains active after a participant stops talking. The setting is selectable in 0.5 second increments.
|
||||||
| Book Drop | To ensure that only the speech from a participant activates the microphone, turn on the book drop feature. This quickly turns off a microphone that has been accidentally activated from a loud noise other than speech. | ||||||
| Last Mic Stays Open | This setting ensures that at least one microphone is always activated. This is useful for video or audio conferences with echo-canceling equipment. |
This setting automatically turns off the microphone when the participant stops talking.
| Automatic Off Time | The time for a microphone to turn off after the participant stops speaking.
|
For increased control over the meeting, the chairman uses the browser interface to activate microphones. The chairman page is dedicated for controlling the speaker list and request queue. The chairman can manually turn on/off microphones, or simply monitor the list in an automatic mode. Using the interface, the chairman can easily:
There are two main lists from the Microphone Control page:
| Speaker List (Red) | The speaker list displays the name and seat number of each active microphone. The list displays in chronological order, with the most recently activated microphone at the top of the list. A red box turns on next to the seat number for quick visual identification. |
| Request Queue (Green) | Delegates in this list are next up for speaking. Primarily useful when operating in First In First Out mode (FIFO), the queue chronologically lists all participants that have pressed their speak button. Once an opening is available in the speak list, the participant at the top of the queue list is automatically turned on. |
For access to the chairman page, enter the IP address of the CCU, followed by /chairman (example: http://172.17.11.137/chairman).
The following buttons are available to the chairman for controlling the microphones during a meeting:
| Speak | Instantly turns on a participant’s microphone. Select this button to view all discussion units in the system, including those in the request queue. Select a participant to add them to the Speak list. |
| Request | Add a participant to the request queue to put them in line for speaking. Select from any participant in the system, excluding the chairman. |
| Next On | Activates the participant microphone at the top of the request queue. If the maximum speaker count has been reached, the new speaker replaces the last one on the list. |
| All Del. Off | Turns off all participant units, leaving only the chairman in the speaker list. The same button appears on the chairman discussion unit. |
| All Req. Off | Removes all participants from the request queue. |
There are two additional audio channels used for language interpretation. In bilingual meetings, participants speak their native language into the microphone and listen to the interpretation on headphones.
Example Setup for Bilingual Meeting
Interpreters use the portable DC 5980 P to transmit simultaneous language interpretation of the discussion. Participants listen to their desired language channel on any microphone unit with a headphone output.
Note: Multiple microphone units can be set for the same interpreter channel to support multiple interpreters at once.
Note: Flushmount DC 5900 F units are not programmable as interpreter units.
Attention: Always use shielded Cat 5e (or higher) network cables for reliable system operation. Ensure the right cables are used and installed correctly before referencing the troubleshooting table.
| The light rings on the microphone are constantly flashing after the system is powered on. |

To assist in troubleshooting, a system-wide report is available from the moment the CCU powers on.
The MXC Firmware Update Utility (FUU) is bundled with the firmware download on the Shure website. Use this program to keep your system updated to the latest firmware version, or to upload image files to compatible conference units. (See the FUU guide for more information.)
The DIS-CCU features an Ethernet connection for the purpose of providing an interface to control and monitor the system. By setting up a simple (raw) TCP/IP socket connection to the DIS-CCU Central Unit, control options are available.
This section describes the TCP/IP raw socket protocol for communicating with the DDS 5900 Discussion System. This protocol provides a short set of commands, enabling a third-party control application to monitor and/or control system status of a DDS 5900 Discussion System.
Some examples of functionality available using the protocol:
This interface supports applications developed by customers, so the protocol is deliberately kept simple. The External Control protocol offers a means for supplementing the control functionality available through the DDS 5900 Browser interface and the DIS-CCU interactive display, however some commands and settings available in the browser interface and on the DIS-CCU interactive display are not available using the 'External Control Protocol'
Customer applications can include but are not limited to AMX® or Crestron® room control systems, PC or micro controller based applications, e.g., for button mimics and camera control applications.
A TCP/IP socket connection to the DIS-CCU must be established for the External Control protocol to become available. Configuration of the DIS-CCU connection to the Ethernet must be defined from the CCU interactive front plate control/Browser interface and an IP address for the DIS-CCU must be assigned in the network.
Choose either a static IP address or an IP address assigned through DHCP. It is convenient to ensure, that the DIS-CCU ends up with the same IP address at each start up.
Knowing the IP address, the only additional information required for setting up a TCP/IP connection is the Port Number:
Port Number = 3142
Example: Test connection to CCU via Putty®: If the DIS-CCU is assigned IP address 192.168.1.100, the external application must connect the TCP/IP socket to the address 192.168.1.100:3142.
Knowing the IP address of the DIS-CCU a connection can be set up using a simple terminal program like Putty.
To control the CCU an External Control sends commands to DIS-CCU included in command lines. Command lines are build up in a very simple manner:
<command><SP><data><CR>
<command><SP><data><LF>
<SP> Space - 0x20 = 32
<CR> Carriage return - 0x0D = 13
<LF> Line Feed - 0x0A = 10
Command lines are terminated by a Carriage Return <CR> or Line Feed <LF> or both. In order to be able to communicate with Windows systems, Linux systems or other systems, the CCU understands both types of command line terminations.
Notice also, there is a space between the command and data. If a command does not carry any data, space is possible but not required.
The CCU is not sensitive to upper/lower case.
Example:
mic_on 212<CR>
Turn on microphone at seat 212. Command = mic_on, data = 212. The 'mic_on' command carries a seat number as data.
Command lines out of the DIS-CCU are just as simple:
<command><SP><data><CR><LF>
<SP> Space - 0x20 = 32
<CR> Carriage return - 0x0D = 13
<LF> Line Feed - 0x0A = 10
Again, to satisfy most systems, the CCU terminates command lines by including both <CR> and <LF>.
Discussion Units are identified by means of a seat numbers. Each Discussion Unit is assigned a seat number. This is done automatically for all discussion units, when they are connected to the DIS-CCU. The DIS-CCU Browser interface is used to change seat numbering.
Seat numbers must be in the range from 1 to 65535.
Generally, a command from an external application is replied to by the CU. But, reply to a command is produced only if actions are taken by the CCU due to the command.
Example: When a 'mic_on' command results in a microphone being turned on, the CCU replies with a 'mic_on' command. On the other hand, if a 'mic_on' command does not lead to turning on a microphone, the CCU does not produce any reply.
There can be several reasons for the CCU to reject turning on a microphone:
The CCU supports streaming of status. When an External Control issues a 'mic_status' or 'audio_status' command, the CCU responds by sending the microphone system status. The same applies to 'audio status'. Therefore, it is possible for an External Control to synchronize with the CCU status.
mic_on <seat no><CR>
Instruct the CCU to turn on the microphone at seat_no.
If the CCU turns on the microphone, it replies with the 'mic_on' command. If the microphone also appeared in the request list, it is taken out of the request list and the CCU issues the 'mic_request_off' command.
mic_off <seat no><CR>
Instruct the CCU to turn off the microphone at seat_no.
If the CCU turns off the microphone, it issues a 'mic_off' command.
mic_all_delegates_off<CR>
Instruct the CCU to turn off all delegate microphones.
A Chairman is not turned off.
The CCU responds to the command by issuing the 'mic_off' command for each microphone that is turned off.
mic_request_on <seat no><CR>
