The computer I am trying to connect it to does not have a GPIB or a RS232 port, so I bought a cheap USB to RS232 adapters to try and connect the device. I still can't connect to the device, however, and when searching through USB in the program it say no instrument found. Ive heard that cheap adapters don't connect to all devices due to poorly designed drivers, and I was wondering if this could be the case? The driver is properly installed on the adapter and the device manager is recognizing it properly, yet the Data Logger software seems to still fail to connect with the instrument. Any ideas?
