LED Indicators

The green LED (ST) is used to indicate the number of satellites currently in lock. If the yellow

LED (SC) is flashing whilst the green (ST) LED is off, then the VBOX has no satellite lock.

If this is the case then check that you have the GPS antenna connector correctly fitted to the

VBOX. Also check that the antenna has a clear view of the sky.

The VBOX will normally lock onto satellites within 30 seconds of power up. However on its first

use it can take up to 20 minutes to acquire satellite lock.

The yellow LED (SC) flashes to indicate start of count. When satellite lock occurs the number of

green LED flashes between yellow flashes indicates the number of satellites in lock.

When a Compact Flash memory device is inserted into VBOX II Lite the blue LED (CF) will flash

to indicate that the VBOX is writing to the device.

The amber LED is used to indicate either CAN activity (CN) or if the unit is a DGPS version (DG), then this LED will come on when DGPS lock has been

successful.

The following diagram shows an example of SAT LED pulse sequence.
