I'm facing trouble getting GBIP address from two exact the same equipment's (Lambda power supply) at the same time.
When I run the test application with both power supplies ON I didn't get reading, on VISA it will show only one instrument with address 6 and without the part number and it is only listed as Instrument 1, I confirmed that the test command sent to both when running test application (power supplies both wake up and start suppling power) when it need to be send to one of them at the time of testing.
When I turn either one off I will get reading and on the VISA it will show the model and the serial number without any problem and the issue will show up again as soon as I turn both on, not sure what causing that because I have other set of the test setup exactly the same hardware and wiring but never have problem on it.
I tried to change the cables and reinstall the programs but still the same, I'm using GPIB-USB-HS
I'm running out of time and any help is highly appreciated, thanks in advance.
