488.1 communication error

[etweeten]

I'm trying to get a ASSY 180xxx board working under Windows 95. The driver loads OK. I then use ibic to test communications with the

an instrument following the initital troubleshooting page at www.ni.com/support/gpib/max/ibic.htm. Also I'm using the E7 revision of the software download

 from NI's FTP site. The following is a transcription of what happens:

ibfind gpib0

gpib0: ibpad 0

[0100]   < cmpl >

gpib0: ibpad 0

[0100]   < cmpl >

gpib0: ibrsc 1

[0100]  <cmpl>

gpib0: ibsic

[1130] < srqi cmpl cic atn >

At this point it doesn't seem like I can do anything. My question is, what is wrong? All looks the same as the troubleshooter page except

whenever I use ibwrt or ibrd I just get timeouts. Also srqi shows up after the ibsic command is entered. Does this say something?

The instrument has a couple of lights(remote,addressed) that turn on too, making it seem that I have properly addressed the instrument!

Any help would be greatly appreciated.

Hi Eric,

The srqi status is indicating that a device on the bus has set the service request line.  The ibsic command should have reset the bus and the device.  Your device might not accept this command, or there might be a problem with the device.  Is the E7 revision that you are refering to NI-488.2 version 1.7?  This is that latest version that supports Windows 95.

There are other easier ways to trouble shoot your device than IBIC commands.  Have you tried using Measurement & Automation Explorer?

This troubleshooting guide shows how to use MAX to communicate with your device.  You can also use NI-Spy along with MAX to capture the driver calls to the device (this is also linked from the site above).  You can save the Spy captures and post them if you are still having issues.
