Omax RS 232 Communications Protocols

Hello,

I have an Omax Jetmachining system from the 2000's that I purchased second hand with an Omax P2040V pump.

The challenge I have is, the computer in the machine has been replaced with an aftermarket controller and won't communicate with the pump. The original computer output through an RS232/485 to the RJ11 on the pump controller.
We can run the pump in a standalone setup, but we really need integration with the new controller for the safety interlocks.
Unfortunately the original computer was binned and I have no way of determining the required protocols to setup out new controller.
If anybody has an image of an Omax they could share or run wireshark and send through the log that would be a massive help.

TIA

Matt
