I have been controlling a power supply connected to my pc via a GPIB cable using VBA. i have now purchased a GPIB to USB Controller as the laptop im using doesnt have a GPIB port. the contoller when installed is seen as a USB serial port. is there anyway of me connecting to the device as i am struggling to work it out. Before i used the GPIB address to connect "GPIB0::1::INSTR" is there anything like this for the USB serial port? using GPIB i could turn the supply on and change the voltage etc.
