We just bought this Romer Arm about a month ago, i just set it up last week and had it working fine. its a CP-C as in the topic title its a wired connection. I was probing, scanning and using it like normal so the next day i come in to reconnect everything and it doesn't recognize the connection anymore, i spent an entire day going over everything i possibly could along side multiple manuals. Today i uninstalled absolutely everything to do with this Romer Arm and it still does not connect. I have tech support via hexagon eventually looking at it but i figured id reach out to the community for the first time to see if anyone else has this Romer Arm or any problems in regardless to wired connections.
when you open pc-dmis click on the Edit tab, then highlight the portable interface tab and select the RomerRDS arm. this should force PC-DMIS to recognize the arm. you should see the numbers fluctuating in the right hand side of the PC-dmis display
