Troubleshooting a PC/104 System

If you have reviewed the preceding table and still cannot isolate the problem with your cpuModule, 
please try the following troubleshooting steps. Even if the resulting information does not help you 
find the problem, it will be very helpful if you contact technical support.

Simplify the system

. Remove items one at a time and see if one particular item seems to cause the 

problem.

Swap components.

 Try replacing items in the system one-at-a-time with similar items.
