Hey! I have an RS-232 device (I know…) connected to the Serial port 0 on the SNAP-PAC-R1 controller, and I’m having trouble (I know!) getting it to communicate to PAC Control. I’ve done serial comms a billion times before, and I’m using code that used to work when they had this device connected to a SNAP-SCM-232 module, so it should work.
In the past, I’ve had success bypassing the Opto serial code and figuring out the communication using a Terminal program. I used to use HyperTerminal, and now I’ve been using PuTTY. I’m not great at this. On the SCM-232 module, you just use the IP address of the R1 with the port that corresponds to the module’s position on the rack and if it’s on port A or B (e.g. 22500). Does anyone know how to set this up with the R1 on-board serial port? I can’t find a reference to the on-board serial port 0 number.
