By default, the GPS16162 comes configured with a base address of 0x2E8 for the GPS UART.
When selecting a base address for the GPS16162, please observe the following guidelines:
•
Every device in your PC/104 system must have a unique base address! When selecting a base address for the GPS16162, make
certain that it does not conflict with any other devices.
•
Base addresses 0x3F8 and 0x2F8 are typically used by serial ports COM1 and COM2, respectively. If you wish to use one of those
base addresses, you will need to disable any conflicting serial port.
•
Some operating systems expect UART devices to be located at the standard serial port base addresses (0x3F8, 0x2F8, 0x3E8, and
0x2E8). Setting your GPS16162 to one of these addresses can make system setup and configuration easier.
JP7: Battery Jumper
Removing JP7 will disconnect the battery from the GPS module. JP7 should remain closed for normal operation.
