GPS Tab

Connect to GPS / Disconnect from GPS:

This button either tries to establish a

connection with the GPS receiver chip or

disconnects the connection.

COM: used to select the COM port for

communication between SatViewer and

your Nomad GPS receiver. Your Nomad

GPS receiver port is set to COM2 and a

baud rate of 9600. The default SatViewer

settings shouldn’t need to be changed to

connect.

NOTE: Before changing COM port or

baud rate settings, you must first disconnect from your Nomad GPS

receiver before making the changes. After you have changed the

COM settings, then you can re-attempt to connect to your Nomad

GPS receiver, using the Connect to GPS button.

Enabling the Microsoft GPS driver

If you would like to connect two or more programs to your Nomad

GPS receiver at the same time (such as SatViewer and a navigation

program) you will have to turn the Microsoft GPS driver on by

performing the following steps:

1. Tap Settings / System / GPS.

2. Tap the Access tab.

3. Tap Manage GPS automatically. This will turn on the

Microsoft GPS driver. Ensure that the GPS program port is

COM3 (or any other port available in the Microsoft GPS driver

screen) and the GPS hardware port is COM2 with baud rate of

9600.

4. The Microsoft GPS driver will now allow multiple applications

to connect to your Nomad GPS receiver at the same time. This

can be helpful so that your Nomad GPS receiver can be

controlled with SatViewer while other applications are also

using your Nomad GPS receiver.

5. In SatViewer and any other program using your Nomad GPS

receiver, change the COM port to COM3 (or the COM port

specified in Step 3 above). Both applications will connect to

your Nomad GPS receiver through the Microsoft GPS driver.
