What exactly does viclear send to equipment on GPIB bus.

[May 476]

It looks like the "viclear" command locks up the equipment and GPIB bus sometimes. What does it do exactly to the equipment? What is the exact command sent to the equipment?

Hi,

viClear calls the NI-488.2 function ibclr. According to the NI-488.2 reference manual, this function send the following commands:

- Talk adress of the access board
- Unlisten
- Listen address of device
- Secondary address of device (if applicable)
- Selected Device Clear (SDC)

Hope this info helps.
