Summary

The Just Video Walls UL 737Poe is an Ultra Series device supporting CLI control via Telnet (TCP port 23) and RS-232 (3-pin Molex debug cable, 115200-8n1). This spec covers USB activation, video output control, and network service management commands. The device shares firmware and OS with the Omega Series.

Notes

  • Source covers Omega and Ultra Series devices generically; they share the same firmware and OS. UL 737Poe belongs to the Ultra Series.
  • Source text references "Just Add Power" as the vendor; entity bootstrap token is "Just Video Walls".
  • RS-232 access requires a 3-pin Molex debug cable (white connector on bottom of unit). Cable must be made or requested separately.
  • Commands execute immediately but may not persist through reboot.
  • All commands are case-sensitive.
  • video off and video on serve different purposes depending on whether the unit is a decoder (HDMI output control) or encoder (HDMI input control). The command string is identical in both contexts.

Known Gaps

- "Source covers Omega & Ultra Series generically; UL 737Poe is not individually distinguished. Unclear whether UL 737Poe is an encoder, decoder, or transcoder — command applicability varies by role."
- "flow control not stated in source"
- "no query/response commands documented in source"
- "no settable parameters documented in source"
- "no unsolicited notifications documented in source"
- "no multi-step sequences documented in source"
- "no safety warnings or interlock procedures documented in source"
- "flow control setting not stated in source"
- "device role (encoder vs decoder vs transceiver) not specified for UL 737Poe"
- "no query commands documented — device state cannot be read via CLI from this source"
