NDAC timeout

[garethmbda]

I am using a NI GPIB-1014P as a GPIB controller.

What method is used to time-out long responses on the signals NDAC and NRFD?

Is any time out period set by default, or is it set by the programmer?

Where is this time-out feature describedin the IEEE 488 spec (if at all-I cannot find it) ?

Thanks.

Hello,

Information about how to work timeouts into your 488.2 application can be found in the manual for NI-488.2. Handshake lines NDAC and NRFD are discussed in the appendix page A3, while different timeout examples are included throughout the guide.

Tom, thanks for your response. We are interfacing to the board using Ada, so we do not use the Labview facilities. Could you please point me to the timeout setting register on the board.

Regards

Hello,

Given you wish to use Ada to program your device unfortuantely I can not provide a great deal of advice given it is not our programming language. All of the register information for the board are described in the manual. You will need to read this manual and architect you application with the funtions described in it.
