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

3.3 Connectors and Jumpers
Figure 2: Board Connections
3.3.1 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.
3.3.2 EXTERNAL I/O CONNECTORS
CN7: Serial I/O Connector
CN7 is an RS-232/RS-422/RS-485 interface that can be configured to be a serial port off the CPU or one of the first two serial ports from the
GPS. Table 4 and Table 5 is the pin out in RS-232 mode, if JP3 has pins 1 –2 shorted.
