6. Global Positioning System (GPS) test:
The VC1727C utilizes the Garmin GPS25-HVS receiver. On-board memory and rechargeable backup
battery allows the GPS receiver to retain critical data such as orbital parameters, position, date and time.
The receiver can track up to 12 satellites and provide fast fix with low power consumption. Flash based
program memory allows software revisions and upgrades through serial port interface.
The GPS requires line of sight contact with at least 4 GPS satellites/transmitters to determine its position.
This means building walls, trees, hills and other obstructions can block the GPS signal.
Step 1:
Select port 4. (The GPS LED should light)
