3.4 Steps for Installing
1. Always work at an ESD protected workstation, and wear a grounded wrist-strap.
2. Turn off power to the PC/104 system or stack.
3. Select and install stand-offs to properly position the module on the stack.
4. Remove the module from its anti-static bag.
5. Check that pins of the bus connector are properly positioned.
6. Check the stacking order; make sure all of the busses used by the peripheral cards are connected to the cpuModule.
7. Hold the module by its edges and orient it so the bus connector pins line up with the matching connector on the stack.
8. Gently and evenly press the module onto the PC/104 stack.
9. If any boards are to be stacked above this module, install them.
10. Attach any necessary cables to the PC/104 stack.
11. Re-connect the power cord and apply power to the stack.
12. Boot the system and verify that all of the hardware is working properly.
NOTE: When using under Windows, the GPS may be incorrectly detected as
a Serial Mouse, causing erratic mouse cursor behavior. This issue
has been documented by Microsoft. For more information, refer to
Microsoft Knowledge Base Article 283063.

5. Check the stacking order; make sure all of the busses used by the peripheral cards are connected to the cpuModule.
6. Hold the module by its edges and orient it so the bus connector pins line up with the matching connector on the stack.
7. Gently and evenly press the module onto the IDAN system.
8. If any boards are to be stacked above this module, install them.
9. Finish assembling the IDAN stack by installing screws of an appropriate length.
10. Attach any necessary cables to the IDAN system.
11. Re-connect the power cord and apply power to the stack.
12. Boot the system and verify that all the hardware is working properly.

5.1 Module Handling Precautions
To prevent damage due to Electrostatic Discharge (ESD), keep your module in its antistatic bag until you are ready to install it into your system.
When removing it from the bag, hold the module by the aluminum enclosure, and do not touch the components or connectors. Handle the
module in an antistatic environment, and use a grounded workbench for testing and handling of your hardware.

5.3 Connectors
5.3.1 BUS CONNECTORS
CN1(Top) & CN2(Bottom): PCIe Connector
The PCIe connector is the connection to the system CPU. The position and pin assignments are compliant with the PCI/104-Express
Specification. (See PC/104 Specifications on page 26)
The GPS35190 is a “Universal” board, and can connect to either a Type 1 or Type 2 PCIe/104 connector.
