2231-A power supply labview communication

Post by sufyank1 » December 25th, 2020, 11:12 pm

I am using a CH340 based USB to DB9 converter inorder to communicate with the power supply via serial communication. Even after installing the specific drivers for the converter, I am not able to receive any response from the Power supply, neither through labview nor serial terminals like putty, NI MAX VISA test panel.

Is the keithley converter necessary to communicate with the device? I am attaching screenshots for your reference, please advise.

check the pin out of the CH340 to the DB9 on the rear of the 2231A power supply.
See the attached PDF document for some general info.
