I am using the ProXR Relay Controller Board 24-Channel DPDT with RS-485 Module. I am having an issue with the communication to the device. Unfortunately, I was attempting to change the RS485 baud rate and in the processes and my lack of attention to detail, I believe I changed the baud rate of the UART comms. Now I have an issue where the controller isn’t responding to anything over RS485.
I’ve tried using configuration mode with the C jumper on the RS485 module and program vs run mode on the relay board and every combination there of. Still no communication.
Tried resetting the controller with the “3.3V to CLR” jumper. Still no communication.
When the C jumper is not installed the “busy” LED flickers every time I send a command, but I get no response . The LED does not flicker when the jumper is installed.
Everything worked before I changed the Baud rate.
Issue seems to be with the controller. I have an identical relay controller setup and it works fine on the same port.
Is there another method of resetting the RS485 module and relay board to factory settings?
Thank you in advance for any help on this.
