Need readings on RS-232 port

Post by gspurushotham » November 11th, 2011, 6:36 am

Hi,

I am using keithley 2700 multimeter, I have written simple script in C# on .net to get the Resistance measurement readings on RS-232 port.
I have configured the rs-232 port and i have enabled rs-232 port.

I am using the front panel to set measurement settings(i.e. omega2 for resistance) but I need the measurement readings on RS-232 port.
for this I have tried below code:
INIT
FETC?
or
Just .. READ?
or
INIT:CONT OFF
FRES:RANG 1e3
FRES:OCOM ON
READ?
For all of the above codes, I do recieve the response from multimeter but it is un readable.
for eg: I receive: +&)?6??1S?0?5,%S?2i?2??M,?&?4?E9G??

Pls help me with code to get proper readings.

Hello,

you should check first the data format you have specified. If not specified, please send the following SCPI command FORMat:ASCii to specify it.
Format for transferring data could be ASCII, SREAL, REAL32, REAL64...
To get readable data, you should select ASCii format.

Hope this can help you. Let me know if I can do more.

Regards,

Mickael Billaud

In telecommunications, RS-232 (Recommended Standard 232) is the traditional name for a series of standards for serial binary single-ended data and control signals connecting between a DTE (Data Terminal Equipment) and a DCE (Data Circuit-terminating Equipment). It is commonly used in computer serial ports. The standard defines the electrical characteristics and timing of signals, the meaning of signals, and the physical size and pin out of connectors.
