I would like to use a PXI-8431/8 module to communicate with some devices over RS-422 trough VeriStand. I know that Instrumunt Add-On Custom Device allows sending messages over RS-422, but when using this add-on comminication structure should be command response. This add-on doesn't initiate any communication.
How can I communicate over RS422 through Veristand? If a custom device is necessary, is there anyone who has used the PXI-843x or similar PXI module before can help me?
