It is not possible to access USB hardware attached to the UR, within Polyscope, without some form of driver (URCap). I'm not aware of such a URCap. Your best bet is to use a Moxa Nport 5150 instead.

The issue is you need something that can convert to the serial commands. It might be possible to write a script that uses tcp/ip sockets to send the serial commands out over an IP to serial converter which is what I think that Adam-4571L does but I am not sure, did not find much information on the web in a quick search. I also searched Moxa as we have used some of their gateway converters to convert modbus to CAN but I did not see one for Modbus to Serial but I did not look too deep. May want to call them and describe what you are trying to do.
Also, another option could be getting the rotary from Vention as they have systems that work directly with UR. Worth a look if you can't figure anything else out.
I was wondering if it was possible to connect to a USB serial converter with the UR? I have a HAAS rotary indexer with a RS232 port that is used to communicate with a CNC, PC, etc. i am using a converter that comes with a Robotiq gripper. i was able to get it to communicate on my pc, but is it possible to do this on the UR with a script?
