INITIAL CONFIGURATION

Prism Flex must be initially configured locally by Web UI or via Prism App. Once connected to Core, it can be remotely controlled with no local access needed.

Web UI

The Prism WebUI allows direct control of all of Prism Flex’s video configuration, network settings,  firmware, licenses, and recordings.

Prism App

The Prism App allows you to configure all of Prism Flex’s settings, monitor your video, and contribute your phone's cellular internet connection to a Teradek Cloud Stream. The Prism App is available for Android and iOS devices and must be used with the Prism on an accessible network.

Connect via Ethernet

  1. Connect one or both of Prism Flex’s Ethernet ports to an Ethernet switch or router.
  2. Press the menu button or navigation buttons to navigate to the Ethernet 1 or 2 screen and obtain a DHCP IP address. 
  3. Navigate to the IP Address
    • Web UI: Enter the IP address in your web browser’s navigation bar to access the web UI
    • Prism App: If the Prism is on the same network as the Prism app, it will be detected.  For advanced networks, use the + button at the top right of the app to enter the IP address manually

Connect to a Wi-Fi Network

Prism Flex supports two wireless (Wi-Fi) modes: Access Point (AP) Mode (default mode for connecting directly to Prism Flex as well as bonding multiple phones for increased bandwidth) and Client Mode (for connecting to external Wifi hotspots).

ACCESS POINT (AP) MODE

  1. Navigate to your device's Wireless Settings and connect to Prism-857-xxxxx (corresponding to the last 5 digits of the serial number).
  2. Once connected, Navigate to the IP Address 172.16.1.1
    • Web UI: Enter the IP address in your web browser’s navigation bar to access the web UI
    • Prism App: The Prism will show up in the menu and can be selected for configuration 

CLIENT MODE

  2. Press the menu joystick twice in the direction indicated, then press and hold the menu joystick to switch to Client Mode.
  3. Press and hold the menu joystick in the direction indicated to scan for available Wi-Fi networks.
  4. Select an available network, then enter the password. Once connected, the display will list the network and corresponding IP address.
  5. Once connected, Navigate to the IP Address 172.16.1.1
    • Web UI: Enter the IP address in your web browser’s navigation bar to access the web UI
    • Prism App: The Prism will show up in the menu and can be selected for configuration  

ENCODER/DECODER CONFIGURATION

Configure your Prism Flex decoder to receive streams from a Prism Flex encoder. 

NOTE: Prism Flex has several streaming modes available such as SRT, RTMP, YouTube, Facebook Live, and now TRT (Teradek Reliable Transport). The following instructions describe how to configure your decoder/encoder using MPEG-TS mode as an example.

1. Connect to the Prism Flex encoder (see previous section) and open the encoder’s web UI. 

2. Open the Streaming menu, then select MPEG-TS as the streaming mode. 

3. Select a protocol, then ensure the Prism decoder is configured to receive the stream using the correct protocol:

  • TCP → TCP
  • TCP Server → TCP Pull
  • UDP → UDP
  • Multicast → Multicast

Encoder Web UI

4. Enter the destination IP address, then confirm the port is set as the default 9710. 

5. Connect to the Prism decoder (see previous section) and open the decoder’s web UI. 

6. Open the Ingest menu, then select MPEG-TS as the ingest mode. 

7. Enter the protocol, ensuring the selected protocol matches the Encoder’s protocol configuration (see step 3). Confirm the port is set as the default 9710.
