Serial Over IP on RUT956 - Data are not coming back to the TCP client

[itgp]

Hello,

On a RUT956 (RUT9M_R_00.07.08.2), I have configured the RS485 connection (/dev/rs485) and tested it via ssh access directly on the RUT to validate the configuration between our RS485 device and the RUT. It works well for serial over console.

But when we change to go to a serial over ip use (server mode), we can send the frame to RUT (echo -ne ‘N1PA*’ | nc 192.168.246.27 8000), can see on the device the answer via a cat /dev/rs485 when we are logged on the RUT in SSH, but the data is not going back to the tcp client who did the request. Like if there is no redirection from serial to tcp client who did the request.

Is there something to check ?

Thanks for your help,
Alex.

Hi itgp,

Welcome to Teltonika Networks Community!

Under IP Filter, can you add 0.0.0.0/0 to allow all IPs? Try to enable or disable Full Duplex in the instance. Kindly check out this link as a guide.

Let me know if this helps.

Hi !
Thanks for your return.
My bad, I made a mistake on the CIDR in the IP Filter .
Thanks, it’s solved !
