Did someone have experience to use downloaded driver for SR 245?

Did someone have experience to use downloaded driver for SR 245 to take data? I used GPIB-USB-HS cable (from NI) to collect data, and corrected GPIB address in the driver, which is found by M&A Explorer. When I ran this program driver, I saw ERROR light flashing one time and Activity light flashing for another time, but I got nothing for data. I used BNC cable to connect input signal in INPORT 1 in the front panel of SR 245, so there should have signal input.  Do I need to change something in the program?

Thanks

Hi Linghui,

Have you tried to communicate with the device through MAX?  When you run the program, are you receiving an error message in LabVIEW?  What does the documentation for the SR 245 say that one ERROR light flash means?

Are you sending the correct termination character?

Thank you.

I used Max to communicate with the instrument, but it doesn't work. When I sent command ?1, and query,  the string recevied is iberr=EABO. When I enter other commands, the Activity LED also blink quickly.

When I ran downloaded driver for SR 245, Acitivity LED and Error LED blinked. I didn't receive any error message, and I didn't receive any output data.

Hi Linghui,

The EABO error usually indicates a timeout.  This could be caused by a few different things such as sending an incorrect command or not appending the correct termination character.  I would check the manual for your device and see if it requires a certain type of termination character, as well as what commands it accepts.  You can also find troubleshooting techniques for this error here and here.

Hope this helps!
