XPression is sending CR LF (carriage return line feed) at the end of the RossTalk messages, which is the correct formatting to terminate a message using the RossTalk protocol. Dashboard is sending a string so its not terminating the message according to the rosstalk protocol.
Instead of using the RossTalk event on the SceneDirector, use a script event and use the GPI.SendBinaryMessage method.

Hi Simon
My problem is not the ogscript.sendUDPString-command from dashboard - that works
The problem is when I send it out of the scene Director with RossTalk.
I made a further step...
I installed wyreshark on a PC to listen what is comes from the XPression PC.
Sending "LED13" with RossTalk in the sceneDirector leads to "LED13......" in wyreshark on the receiving PC or HEX 4c 45 44 31 33 0d 0a 00 00
I think we can forget the following 00s.
The first HEX part is my LED13, the 0d 0a is LF, so I think XPression sends my command LED13 plus LF
So now what? The receiving PC has to compare the incoming string to go on, but what is it, how does it look like?
I tried LED13LF, LED13chr(10), LED13\n, LED130d0a, LED13U+000A, nothing works
Does anybody has an idea???

Hi Markus
Try adding + chr(13) to the end of your string. So send "LED00" + chr(13) to your UDP port in XPression. I think the chr(13) bit gets added automatically in ogscript.SendUDPString

Hi all
I have a problem sending udp commands out of the scene Director to a brightsign player.
I declared a GPI Board - Smart GPI / Rosstalk in the Hardware settings.
When i now send the Rosstalk (udp) command LED00 to the brightsign player nothing happens.
When i do the same via Dashboard with
ogscript.sendUDPString('192.168.2.141', 5000, 'LED00');
it works.
It Looks like the sended command is not only LED00.
It seems like being one or several signs at the end.
Can anybody tell me what sign/s there are.
Thx in advance
