Yea im trying to get my ims to communicate with tac20 so i can check the ports, I've tried on a couple different units to verify but I keep getting the unable to open the serial port, COM2 message I've tried changing the com port in the communications tab under configure in ims but no luck yet. I've order a new 25 to 9 DB connector and tripplite aswell. This is way I've taken the long way of troubleshooting the SPI error 🤣
