Prism Flex Quick Start Guide

Updated

With flexible I/O and a compact, low-power design, Prism Flex easily fits into any workflow. Prism Flex is perfect for placement on a table top, camera-top, or wedged between your video switcher and audio mixer. Prism Flex can encode or decode up to 4Kp60 video with stunning 10-bit 4:2:2 image fidelity. The Prism platform supports many common streaming protocols such as MPEG-TS, RTSP/RTP, RTMPS, and SRT, and can be connected to Teradek’s Core Cloud Platform for even more flexibility.

GET ONLINE

Use Prism Flex’s web UI to connect Prism to a network and get online. 

Connect to a WiFi Network

Prism Flex supports two wireless (Wi-Fi) modes; Access Point (AP) Mode (for bonding multiple cellular devices for increased bandwidth) and Client Mode (for normal Wi-Fi operating and connecting to your local router). NOTE: You must connect to the web UI in order to switch to Client Mode or to a different network.

1. Connect your phone or laptop to Prism Flex’s network, Prism-855 XXXXX (XXXXX represents the last five digits of Prism’s serial number). 

2. Enter the default IP address 172.16.1.1 in your web browser to access the web UI. 

3. To switch to Client Mode: From the web UI, navigate to the Network Settings and select WiFi

4. Select Client as the WiFi Mode  

5. Click the WiFi scan tab, select an available network, then enter the password. Once connected, the display will list the network Prism Flex is connected to. 


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 to navigate to the Ethernet 1 or screen and obtain the IP address. 

3. Enter the IP address in your web browser’s navigation bar to access the web UI. 


Connect via Node II or USB Modem

1. Attach a Node II or USB modem to one or both to Prism’s USB-C ports (G) using a 4-pin to USB-C connector cable, and/or a USB to USB-C adapter. The front panel will indicate that the modem has been detected and connected to the carrier.

2. If the modem is not detected, connect your computer to Prism Flex’s AP network (see Connect to a WiFi Network), then enter the default IP address 172.16.1.1 in the navigation bar to access the web UI and configure the modem from the Network menu.

Configure Node II

1. Navigate to the Network menu and select the corresponding USB (Node II) modem.


2.  Select the slot with the SIM you will be using (Slot 1 or Slot 2).

NOTE: Node II supports most provider's SIM card and can operate on most LTE/4G/3G data bands. With dual SIM slots, you can swap from one provider to another without needing to unplug the Node II. Only one SIM card can be used at a time.


3. Enter altanwifi (for Telna SIM cards intended for use in the United States) or internet (for Telna SIM cards intended for use in Europe) into the selected slot's APN field (Slot 1 or 2). 


4. Ensure that both Configuration mode and Authentication method are set to Auto.



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, and Facebook Live. 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.  


Decoder Web UI



PRISM APP

The Prism App allows you to remotely configure all of Prism Flex’s settings while monitoring your stream’s destination, bitrate, bonding status, and resolution to ensure you maintain a stable stream. The Prism App is available for iOS devices.

MAIN DISPLAY
• Main Screen - 
Displays the preview, streaming destination, audio and video bitrates, and resolution of your livestream.
• Link/Unlink iOS Device - Tap the Link/Unlink iOS tab to enable/disable the use of your cellular phone’s data as an Internet connection.

STATS
Tap the Stats button at the top of the screen to display Prism’s serial number, current audio and video bitrates, runtime, recording status, IP address, and network.

RECORDING

Prism Flex encoders support recording to an SD card. Each recording is saved with the same resolution and bitrate set in Prism Flex. 

1. Insert a compatible SD card into the corresponding slot. 

2. Enter the Recording menu, and select Enabled.  

3. Create a name for the recording, select a format, then enable Auto-Record (optional). 

RECORDING CONSIDERATIONS
•  Recordings are triggered manually or automatically. If Auto-Record is enabled in the Recording Settings, a new recording is automatically created when a broadcast starts.
•  For best results, use Class 6 or higher SD cards.
•  Media should be formatted using FAT32 or exFAT.
•  If a broadcast is interrupted for connectivity reasons, recording will continue.
•  New recordings are automatically started after the file size limit is reached.



CORE

Prism Flex can be remotely accessed, configured, and controlled using Teradek’s Core Cloud management and routing service. With Core, you can:

•  Bond multiple Internet connections, increasing your broadcast’s bandwidth and reliability.
•  Remotely control Teradek encoders, decoders and bonded systems from anywhere in the world.
•  Stream to multiple destinations.
