Using SCXI Chassis 1001, system will not recognize 1162, 1163 or 1102 modules.

I'm using an SCXI system with a 1001 chassis, labview 6.0 and MIO-16E card.  However, the system will only recognize my 1102B and two of my four 1124 modules.  It will not recognize the other 1124 modules or the 1164, 1163 and 1102 modules, and I don't know why.

Hi NickB25,

What happens when you switch the slots that the modules are in?  Can you replace one of the working modules with, say, the 1164 and see if that one works?  In other words, is it only those two slots that are working, or are those 3 working modules recognized in any slot?

Thanks,

Hey Justin, thank you for responding to my message.  As it turns out, the working modules can be detected in any of the 12 slots of the 1001 chassis.  However, the 1164, 1163, and 1102 modules will not work in any of the slots.  I've tried switching out components and using a different chassis, adapter, pc, and DAQ device, systematically changing out one component at a time, but I still get the same results.  I've also tried updating the driver to the latest version available.  The only conclusion that makes sense is that the 1102 modules are bad.  I'm going to try ordering a new 1102 and see if it will work.  If not, then I know it's not the cards and maybe I can return the new module.

But what still bothers me is that I was able to get a new 1124 module to work by placing it next to a 1102B module that is connected to the DAQ device .  The new 1124 module will not work if it is directly connected to the DAQ device itself.  What's even stranger is that my older 1124 modules WILL work if directly connected to the DAQ device.  I was wondering if NI has modified the 1124 in such a way that thier new ones can only operate in conjunction with other modules.

Thank you,

Nick

Nick,

It sounds like the 1124 is just configured incorrectly.  There are actually some hardware jumpers on that device that you need to configure depending on the device you are connecting it to.  See the following KnowledgeBase article for more information:

Why Can't I Auto-Detect Modules in My SCXI System When Cabled to an SCXI-1124?

As for the other modules, there could be a hardware issue.  You may want to try sending in your module for repair before going out and buying a new one (especially if any of the modules are still under warranty).  The best way to do this is to request support online, where you can talk to an Applications Engineer directly about the issue you are seeing.
