SKU: R45PL - 4 channel relay board

I have been able to find the serial commands to turn on and off the individual relays. Are commands to turn all on and off? Is there a list of available command.

Hi,

You can find a complete list of commands at: https://ncd.io/proxr-quick-start-guide/.

I think you’re looking for the commands in section 2.7: https://ncd.io/proxr-quick-start-guide/#document-8
