Dear friends and Respected Seniors,

I am doing a project where I have to control HP34401A DMM through computer using RS232 communication. Programming language is C. Now I need to write a program which will perform the following instructions
1. Set the BAUD RATE to 9600
2. Set no Parity
3. Set 8 data bits
4. 1 start bit
5. 2 stop bits

First step I should be able to read the voltage on HP 34401A DMM through computer.

I am in urgent need of this program and will be very glad if some1 forwards it to me in my email. I don't need the entire program, but just a part of a program (Which header files and functions should be used, if Linux is the operating mode etc.) that will help me to set these parameters.

After that I will be programming SCPI commands and with the help of that I can finish my project!

looking forward for your help! thanking u all.

Regards,
Arnab

 

Dear Arnab:
In this days I am trying to take measurements from the HP34401A via RS232 in C languaje. I could sent comands of configurations (REM, LOC, CONF:VOLT:AC) but I coul not take the data after the measurement (MEAS:VOLT:AC?). Could you managed to do that?. IF so, please send me an example program. Thanks in advance.

Hello. I need to work with the HP34401A multimeter using python through window10. RS232 is the connector. Can you please send me the programme you used on that time. Thank you,
