Communicating outside bartendro UI with the pumps and router

Hi there. I'm trying to use the bartendro pumps in a setting not intended for drink making. Problem is, I cant seem to find how the 10byte packets are assembled to be sent through the raspberry pi's RS232 serial connection to the router board.

Does anybody know how I can send a packet through the pin out and have a template or an example of what the code is supposed to look like?

I'm running it on a Raspberry Pi Model B with Raspian

Thanks!
