Problem with Remote RS232 Connection With E4418 Power Meter

[Faraz001]

Hi. I want to have remote connection with E4418 Power meter and i have some problems. i wanna have Serial RS232 Connection with the power meter. i have set the configurations and it is correct ( i have chosen "echo On" and when i send a command at RX pin, i get the same command at TX pin. the problem is that my commands are not applied by the power meter. for example when i send "*IDN?\n" i get nothing or when i send "SYSTem:LANGuage?" i get nothing. may u help me?

Do you have the correct rs232 cable for your device.

Basically there are two versions with 9 pin adapters. one that is straight through and one that swaps Rx and Tx and a few other lines.

So you can easily measure if you have a straight or swapped cable (also called null modem) by measuring if 2 and three are swapped or not.

In your case I would use the other cable.

Do all parameters given by the instrument if you use the System/Inputs button ->Remote Interface->Interface Overview match your PCs setup ?

Hi. Yes My cable and connections are correct

Hi. Yes everything were matching. Actually i found the problem. i was not sending 0x0a (Line Feed Character) after the commands so the commands were not being applied. 

Thank you everybody
