How to clear SRQ line?

[askguy]

Hi Albert,

I understand what your mean!

Actually i implemented two button on slave application, one button is call ibrsv 85, another button is call ibrsv 0.

when i call ibrsv 0, the SRQ line was cleared of course. I mean serial poll from controller does NOT clear SRQ line if slave does nothing, the SRQ line state was controlled by slave.

I have a question how can slave to know(or detect) whether it was asked for status, thank you!!

Hi Alert,

I'm looking forward to getting your answer, thank you very much!

that is handled in the chip that normally is situated in the slave.

In this case you have to look how to be a real slave in the gpib-board.

I searched a lot of NI offical gpib manual, and could not find a way to detect whether Slave has been serialpolled by Contoller.

Anyway, thank you very much!
