Setting Up Your First Device

  1. Install Your Devices:

    Connect each of the Stem devices you purchased to your network and place them in their designated spot in the room.

  2. Access Your Devices:

    To access the Stem Ecosystem Platform, open the Stem Control app, or type in your device's IP address in your web browser. Access your connected devices through the Ecosystem tab.

    Screen shot of the Stem Ecosystem Platform home screen.

    Note: The Stem Platform is integrated on every Stem device. The IP address of any Stem device gives you access to the Platform. When working with more than one Stem device, make sure all your Stem devices are connected to the same network.

    More information and functionality are available at each of the home screen tabs:

  3. Choose Your Security Setting:

    Organization allows you to password-protect all your connected Stem devices with a single password. Default settings do not require a password to access devices.

  4. Create A Room:

    Rooms allow multiple devices to work together. Click Ecosystem > Rooms > Add Room to create your first room.

Security Settings

The Organization setting allows you to password protect your Stem devices with a single password. The Default setting removes the requirement to enter a password to access a device.

Organization Security Setting

The organization password is required to access or make changes to your Ecosystem devices. Organization information is stored within each device. Only one password is allowed per organization, only one organization is allowed per network, but there is no limit on rooms or Stem devices allowed in an organization.

Note: If you forget your organization password, contact Stem customer service.

Default Security Setting

No password is required to make changes or add Stem devices to your Stem ecosystem. This means anyone with access to your network can control your Stem devices. Stem devices without password protection are open to reconfiguration and setting changes.

Ecosystem

Three features are accessible from the Ecosystem tab of the Stem platform: Rooms, Devices and Design Wiz. Rooms and Devices allow you to control and manage your rooms and devices. Design Wiz allows you to design new rooms for your Stem devices.

Stem Ecosystem Setup

Your Wall, Ceiling, Table or Speaker can be set up on their own for standalone use, or multiple devices can be used in a room together.

With a multi-device setup, Hub or Hub Express is required. Hub and Hub Express enable all endpoints to communicate with each other and provide a single point of connection to external loudspeakers, Dante® networks (Stem Hub only), and other conferencing interfaces for all devices.

Stem Control provides complete access to the Stem Ecosystem Platform, as well as integrating with your preferred video conferencing platform for touch-to-join meetings.

  1. Place or mount the device in the desired location.
  2. Connect the device to a network port that supports PoE+ using an Ethernet cable.
  3. Install all other Stem devices, including Hub or Hub Express, to the same network.
  4. Access the Stem Ecosystem Platform to configure your devices.

Stem Hub & Hub Express

Overview

Stem Hub and Stem Hub Express act as the brain of a room, connecting your network of Stem Ecosystem devices to external loudspeakers and other conferencing interfaces over USB Type B, Dante*, or SIP.

*Stem Hub only

  2. Install the provided Philips head screws at the marked positions. Use the provided drywall anchors as necessary.
  3. Align the keyholes on the back of the device with the screws. Lightly push in and down to lock into place.

Illustration showing the keyholes for mounting the Stem Hub or Stem Hub Express.

Setting Up

Stem Hub and Stem Hub Express enable all endpoints to communicate with each other and provide one place to make connections to external loudspeakers and other conferencing interfaces for all Stem Ecosystem devices.

  1. Connect Hub or Hub Express to a network that supports PoE+ using an Ethernet cable. This connection provides the device with power, data, and other IoT and SIP capabilities.

    Note: If your network doesn’t support PoE+, use a separate PoE+ injector or PoE+ enabled switch.

  2. Plug your audio and conferencing devices into Hub or Hub Express using the following connectors. These connections will be utilized for all Stem Ecosystem devices on the network.

    USB (Type B): Enables video and audio conferencing capabilities when connected to your PC.

    External Speakers: A female terminal block connector (unamplified) for external speakers or amplifiers. Use with the provided male terminal block connector.

    Dante*: Creates a single Dante output and input channel for all devices.

    * Stem Hub only

  3. Complete your setup using the Stem Ecosystem Platform.

    Important: To ensure that external loudspeakers perform properly, use Stem RoomAdapt.

Directional Array

During a call, proprietary beamforming technology steers the microphone array toward voices in the room, canceling out sources of noise. This provides superior intelligibility for the persons listening at the far-end of the call. Beamforming dynamically adjusts to changes, with blue indicator lights showing the direction of each audio beam as it detects and follows the voices in the room.

Volume Control

Change the speaker volume using the + and - buttons on the top of the device.

Mute Button

During a call, use the mute button on the top of the device to toggle the microphone on or off. When muted, the light ring on the device will slowly pulse red.

Setting Up

This device can be installed as a standalone unit or networked with other Stem Ecosystem devices using Stem Hub or Stem Hub Express.

With either setup option, this device must be connected to a network port that supports PoE+. This connection provides the device with power, data, and other IoT and SIP capabilities.

Note: If your network doesn’t support PoE+, you should purchase a separate PoE+ injector or PoE+ enabled switch.

Standalone Setup

  1. Place or mount the device in the desired location.
  2. Connect the device to a network port that supports PoE+ using an Ethernet cable.

Stem Ecosystem Setup

With a multi-device setup, Stem Hub or Stem Hub Express is required. Hub and Hub Express enable all endpoints to communicate with each other and provide a single point of connection to external loudspeakers, Dante networks (Stem Hub only), and other conferencing interfaces for all devices.

  1. Place or mount the device in the desired location.
  2. Connect the device to a network port that supports PoE+ using an Ethernet cable.
  3. Install all other Stem devices, including Hub or Hub Express, to the same network.
  4. Access the Stem Ecosystem Platform to configure your devices.
