    Using a Third-Party Control System

    This device can be controlled using a third-party control system with the appropriate command string.

    Common applications:

    • Mute
    • LED color and behavior
    • Loading presets
    • Adjusting levels
    • Integration with camera systems

    The device is connected via Ethernet to a control system, such as AMX, Crestron or Extron.

    • Connection: Ethernet (TCP/IP; select “Client” in the AMX/Crestron program)
    • Port: 2202

    If using static IP addresses, set the Shure Control and the Audio Network settings to Manual in Designer. Use the Control IP address for TCP/IP communication with Shure devices.

    See below for all supported command strings. This list is updated with each firmware release.

    Using PuTTY and Other Telnet Clients

    For all Telnet clients (including PuTTY), set Telnet negotiation to disabled or passive mode. Active Telnet negotiation is not supported by MXA devices.

    If using PuTTY to enter commands for MXA devices, the first command you send may return an error. To fix, enter the command again and it should work normally.

    Channel Number Assignments

    MXA920 microphones use the following numbering to distinguish the channels for REP values.

    Automatic Coverage On

    • Coverage areas: 01–08
    • Automixer output: 09
    • AEC reference input: 10

    Note: The 0 (all channel) index only reports the automixer output when automatic coverage is on.

    Automatic Coverage Off

    • Dante outputs: 01–08
    • Automixer output: 09
    • Post-gate channels: 01–08
    • AEC reference input: 10

    Commands for Camera Systems

    Use these commands when integrating the device with a room's camera system.

    Tips for Integrating with Camera Control Systems

    Use these tips to get the best results when integrating the MXA920 with a room's camera tracking system.

    • Talk toward the microphone
      • When possible, ask talkers to speak in the direction of the microphone. The microphone may take longer to send talker positions if they are facing 90 to 180 degrees off-axis from the microphone.
    • Speak up
      • Ask quieter talkers to speak up. The microphone can take longer to send position information for quieter talkers.
    • Prep the room
      • Acoustically treated rooms that are less reverberant usually sound better and help improve your microphone signal. In more reverberant rooms, the microphone can take longer to send talker positions or report inaccurate position data.
    • Move closer for single-talker framing
      • If you need to frame 1 talker at a time with the room's camera, set things up so that the microphone is about 10 feet (3 meters) from the different talker positions. The MXA920 performs well with talkers that are up to 16 feet (4.9 meters) from the microphone, but moving closer helps room cameras with single-talker framing.
      • Position talkers so that they are no more than 90 degrees off-axis from the microphone.

    Talker Position

    Get active talker positions in a reporting period in the form of X/Y/Z coordinates in centimeters. Control how often talker positions are reported by adjusting reporting period. The reporting period setting is persistent across power cycles.

    Talker positions outside of coverage areas or lobes are not reported.

    MXA920: Works with automatic coverage on or off

    Parameter Name:
    • TALKER_POSITION_RATE
    • SAMPLE_TALKER_POSITIONS
    Command Types Supported: GET, SET, SAMPLE, and REP
    Indexing: n/a
    Value(s): rate represents how frequently talker positions should be reported. If there is no active talker in the reporting period, there is no report.

    Valid rates are

    • 0: Disable reporting of talker positions (default setting)
    • 100–99999 ms in 1 ms increments
    • If the requested rate is invalid (1–99 or greater than 99999), device reports the current setting.
    • Value in SET command can be 3 to 5 digits
    • Value in REP command is always 5 digits long (00100 = 100 ms)

    POSITION[1..n]: consists of 1 to n sets of talker positions. Each set is in the form of {LobeID} {CoveragaAreaID} {X Y Z}{reserved}. If there are multiple talker positions in a reporting period, the data are combined and reported with one command.

    • {LobeID}: Lobe number where audio is detected: 1-8. Always reported, regardless of automatic coverage setting.
    • {CoverageAreaID}: Coverage area number where audio is detected.
      • Automatic coverage on: 1-8
      • Automatic coverage off: 0
    • {X Y Z}: These are the coordinates where talker audio is detected, relative to the center of the device (in centimeters). {X Y Z} are defined as:
      • X: Direction parallel to the LED bar (square microphones) or 45 degrees to the LED bar (round microphones).Valid ranges:
        • MXA920: −1524 to +1524 cm (−50 to +50 ft.)
      • Y: Direction perpendicular to the x-axis (square microphones) or 45 degrees past LED bar (round microphones). Valid ranges are the same as in X.
      • Z: The distance down from the device. Valid range: 0 to 914 cm (0 to 30 ft.) in 1 cm increments.
    • {reserved}: For future use and set to 0.

    Orientation Example

    The following diagrams are looking down at the device from above. Example coverage areas are 30x30 ft. (914x914 cm).

    Orientation diagram showing how to find the X and Y axes when using TALKER_POSITION commands.
    Example(s):


    < GET TALKER_POSITION_RATE >
    < SET TALKER_POSITION_RATE rate >
    < REP TALKER_POSITION_RATE rate >
    < SAMPLE TALKER_POSITIONS POSITION[1..n] >
    < REP ERR >

    Example of reporting 2 talker positions in a reporting period:

    • Talker 1 is at (X1, Y1, Z1) = (-1524, 321, 914), which is covered by lobe 1 in coverage area 2
    • Talker 2 is at (X2, Y2, Z2) = (123, -321, 914) which is covered by lobe 2 in coverage area 3
