Hi,
I'm having trouble controlling my Power supply(GWInstek, PSP-603, RS232 port) via GPIB-RS232 converter(http://www.ni.com/en-us/support/model.gpib-rs232.html) in Labview.
My PC has both GPIB and RS232 port, but I wanted to leave my RS232 port for other instrument, so I bought this converter.
So now I have PSP603----RS232 cable(customized by GWInstek, pin2,3 crossed)--->GPIB-RS232 converter-----GPIB cable---->PC.
I searched for other articles and successfully set up my converter to G mode (using GPIB Serial Converter software) and set the baud rate to 2400 which is proper for my PSP-603 as below.(And also got the same result using 'VISA read' and 'VISA write' in Labview.)
But I'm not able to communicate with my PSP-603 via NI Max.(below picture, L\r\n is the command given by PSP-603 Manual. The command works very well when I connect PSP-603 to my PC RS232 port using RS-232 cable. So the instrument or the command is not the problem.)
What am I missing now? This is the first time using GPIB-RS232 Converter, so everything is new to me. Anything you suggest would be helpful to me.
Thanks,
