Board Installation
Installing the Hardware
The GPS6185HR can be installed into a PC/104 or PC/104-Plus stack. It can be located almost
anywhere in the stack, above or below the CPU.
Note:
If the GPS6185HR is installed in a PC/104-Plus system, be sure to not break the chain of
PCI devices (such as stacking the GPS6185HR between two PC/104-Plus boards).
Static Precautions
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.
Steps for Installing
1. Shut down the PC/104 system and unplug the power cord.
2. Ground yourself with an anti-static strap.
3. Set the Base Address and IRQ jumpers as described in the previous chapter.
4. Line up the pins of the GPS6185HR’s PC/104 connector with the PC/104 bus of the stack
and gently press the board onto the stack. The board should slide into the matching
PC/104 connector easily. Do not attempt to force the board, as this can lead to
bent/broken pins.
5. Attach the external antenna to the MMCX connector.
6. If any boards are to be stacked above the GPS6185HR, install them.
7. Attach any necessary cables to the PC/104 stack.
8. Re-connect the power cord and apply power to the stack.
9. If the system has a PCI bus, enter the BIOS setup and reserve the GPS6185HR’s IRQ as
a Legacy ISA resource.
10. Apply power to the system, and verify that all of the hardware is working properly. Once
power is applied, the GPS receiver will automatically initialize.
Configuring Software
The GPS6185HR uses a standard serial port UART for host communication. Therefore, you
must “install” a serial port under your host operating system for the GPS6185HR to be
recognized.
If the GPS6185HR was installed using a standard serial port base address (0x3F8, 0x2F8,
0x3E8, or 0x2E8), your operating system may detect the GPS6185HR’s UART automatically. If
