Prism Flex Mk II Quick Start Guide (2024)

Updated on

With a flexible I/O and compact, low-SWaP design, Prism Flex Mk II easily fits into any workflow. Prism Flex Mk II is perfect for placement on a table top, camera-top, or wedged between your video switcher and audio mixer. Prism Flex Mk II 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 TRT, SRT, MPEG-TS, RTSP/ RTP, and RTMP(S), 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: Use the Menu Navigation buttons on the front panel to navigate to the Ethernet screen (1 or 2) and switch from DHCP to Static Mode or 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 5G or Node II

1. Attach a Node 5G or Node II to Prism’s USB port (G) using a 5-pin to USB connector cable, and/or attach another Node to Prism's 5-pin USB input (H) using a 5-pin to 5-pin connector. 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 5G/Node II

1. Navigate to the Network menu and select the corresponding Node modem.


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

NOTE: Node 5G supports most providers' SIM cards and can operate on most LTE and 5G data bands. You can switch from your carrier's SIM (Physical) to Teradek Data (eSIM) without unplugging the Node 5G. Node II supports most provider's SIM cards and can operate on most LTE/4G/3G data bands. With dual SIM slots, you can switch from one provider to another without unplugging the Node II. Only one SIM card can be used at a time. 


3. Select Teradek Data Priority or Teradek Data Standard (depending on your SIM and plan) from the Configuration drop-down menu.


4. Set the Teradek Carrier Mode to Auto Carrier. For Carrier Locking mode, click here.

5. Click Save when you're done.

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.

•  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.

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.
•  Sync your recordings.
