hello, im trying to control the Modbus PoE Eth Relay over UDP.

the Relay accepts Hex commands but i cant figure out how to send hex commands with udp in brightsign. i was able to send udp to the relay and it received it, but nothing happened. is there something i need to do for brightsign to be able to send hex commands over udp? i saw that there is a plugin from 11 years ago for this purpose but it didn't work when i tried it, the relay didn't receive anything

im using the AU335.

 

these are the commands im trying to send:

All relays on: 01 0F 00 00 00 08 01 FF BE D5
All relays off: 01 0F 00 00 00 08 01 00 FE 95

when i use a udpsender from my pc it works

  Are you trying to send these bytes using BrightAuthor, BA Connected, or a script? In any case, it would be a good idea to use something like UDP Sender, which is a Windows application for diagnosing what you’re actually sending from the BrightSign side. If you point the BrightSign device at your computer and run a listener on the computer, you can see what’s coming in.

  ps. The other answer is AI nonsense. AI is unfortunately very confident but unskilled in BrightSign tech.
