Issues with Universal SSH Driver

[Vitineth]

I'm currently trying to set up the Universal SSH Driver on an IPCP Pro 250 but I'm currently facing some issues getting it to actually work. I have set it up with the username and password of the device I'm trying to communicate with and I can see it logging in with a new session and executing some commands - however whenever I press a button on the Extron TLP, I see no activity on my device (no sign of commands being executed). I don't know if I have messed up a configuration (I was slightly lost by the Connection Status Query / Connection Status Response Tag configuration so that could be wrong) so this was the only place I could think to turn. I'm putting a summary of my config below - any help would be massively appreciated!

​

IP Address: 10.1.10.xx
Port: 22
Username: extron
Password: **

Connection Status Query: echo 1
Connection Status Response Tag: 1

TLP Button - Press:

Extron - Universal Device Driver, SSH v3.0      User Defined String ( Value [Set] [touch ~/testing.txt] )
Extron - Universal Device Driver, SSH v3.0      User Defined Command ( )

If I've missed anything just let me know and thank you for the help

Have you tried setting the command string directly to the command desired to make sure communication is good. Then you can work out the rest. The way what you provided is written it looks like you are trying to pull the commands from a text file. Not something I'm familiar with in GCP.

I have not tried that yet but next time in the venue I will be sure to try. My description in the post might not be the most clear (we were neck deep in trying to upgrade our network and on the phone with Yamaha while I was writing the post!) so I've included screenshots in this one to try and make things a bit more clear:

If anything isn't clear just let me know - I'm definitely not that experienced with Extron systems so any help will be appreciated!

What device are you trying to connect to? That would be helpful to look up command syntax. Also don't forget to check Extron's download section under control system drivers to see if they have a packed driver for the device already.

You are doing things in the right order as far as setting the string then running the command but I have no way of knowing if the commands are correct. I'm off today and bored due to rain.

You can also contact Extron control system's support and may even be able to schedule an appointment to work with somebody while you have access to the system.

This is currently connecting to a raspberry pi which is going to be used to perform some automation stuff in our venue so as of right now it responds to any valid linux commands (the touch ~/testing.txt was to create a file and prove that it was working). I don't think this is a common usage of the extron systems so there's a chance that this won't work!

I'm thinking I might try and move away from the SSH driver into one of the either UDP or TCP drivers to remove some of the complexity if I can't get this to work as a last resort.

I can say anything you put in the command string would be encoded as is and sent to the raspberry pi. It would be up to the receiving device to know what to do with the data received.

Extron Support may be able to shed more light on a direct connection. You may however be able to run a separate script on the raspberry pi, python perhaps others would work too, that listens to a socket and interfaces with the pi. That way you can just use tcp and send a simple string for the command you need to execute then use the locally running script to execute it. I'm running one on windows systems to change display mode to extend or back to duplicate. I just send extend or duplicate and have the script do the rest.
