RS232 ProXR lite 4 channel relay comms issue

Hi,

We are having an issue with the 232 relay on a new install. We have used in the past with N-button lite and I don’t recall having any issues setting up. The relay is powered and appears to be getting the commands on RX which is blinking, but we have no TX from the device. I have performed a loop test and the path works fine. I did notice that the Green “ready” LED was damaged during install and removed - but not replaced.

Baud rate has been set via N-button Lite and we have checked, 9600, 38400 and 115200 all to no avail. I am not sure where to go from here, so nay guidance would be greatly appreciated. I have the ProXR manual, but nothing separate for the Pro XR Lite - if there is a difference…

Naturally we are supposed to be heading out to sea in the next 20 hours and are trying to get this working asap…

Thank you for any advice!

Have you tested the relay controller with our NCD Base Station software here:

If not I would recommend that first. The LED being removed will not affect functionality of the board.

Thank you,
Travis Elliott
