Hi, do you know, is it possible to communicate with 34410A withought any drivers? Only connect usb to PC and type SCPI commands in serial terminal, for example RealTerm. I tried to do this, but agilent always said: "Error", and no feedback in terminal. I use a RS-232/USB. In LabView it works good. Maybe i lost some preferences? CR, LF... In future i would like to connect a ESP8266 to rs-232 and get data from it. Thanks

You will need the NI-VISA loaded. Connect the instrument using VISA Write, Read, and Close only. As the instrument does accept SCPI commands, the rest is easy.The other case is the '-1' case. When the command does not require a query, it skips the VISA Read. This case wires the three outputs straight across to its inputs.

Hi,
Make sure your com setting are correct.
baudrate = the default is 9600
parity =none
databits = 8
stopbits = 2
I think you have to enable dtr.
after that is you need to send the ":SYST:REM" command to put the meter into remote serial mode
good luck,
Curt

The device will default to remote control without the
:SYST:REM
command. Additionally, many devices communicating directly on USB also do not require any settings.
