Hi everyone, I've been trying for hours but I can't connect to my multimeter using the RS-232 interface.
I checked everything: the protocol settings, the settings on the multimeter, the null-modem cable, downloaded agilent utilities for connecting to dmms, used two PCs, verified with an oscilloscope that the signal is present, correct, and has correct voltage levels. Nothing, the multimeter doesn't respond to anything.
I'm using putty to send serial command and recieve no response when sending SYSTem:REMote command or *IDN? command.
Did I miss something? I'm really starting to think that there's a problem with the rs-232 interface in the multimeter...
Do you have any idea?
Edit: I had an "Eureka" moment and said "Of course! I didn't send the newline character!". Well, even with the newline character it doesn't work...
I really don't want to spend 100+ euro for a GPIB cable...
