I am only interested in the serial port, since my PC is too far away from the instrument for USB connections.
a serial cable can easily be 10meters, but usb can not.
RS232C in a DB9 connector should be a very simple industrial standard,
some variations exist, so for clarify it could have been nice to see the pinout and handshake requirements explained in the user manual,
i dont get any answers on *IDN? i am in 8n1 9600 baud and scpi mode
i also tried the talk only mode, and still dont see any kind of data out,
double checked with a scope.
any kinds of help you maybe able to come up with, is much appreciated,
