3. Connectors and device status leds
3.1. Front panel
There are 3 leds on the front panel that show the status of device operation. The
following image shows the location of front panel LEDs and connectors.
Leds:
•
Green LED
- illuminates when receiving a signal from RF (indicates the channel is
busy),
•
Yellow LED
- lights during transmission, when the device sends an APRS data
packet,
•
Red LED
- blinking is dependent on current device state:
•
one short blink (0.1 second) per 1.6 seconds – no GPS NMEA sentence
received within last second, GPS disconnected,
•
two short blinks (0.1 second each) per 1.6 seconds – GPS NMEA sentence
received but no position fix,
•
three short blinks (0.1 second each) per 1.6 seconds – GPS NMEA sentence
received with position fix,
•
one long blink (1 second) per 1.6 seconds – APRS packet was properly
received.
Connectors:
•
SMA female
– 50 Ohm RF antenna connector,
•
Mini DIN 6-pin
– one RS-232 serial data interface,
Please never power-up the device (via 12V rear panel power input) without proper
antenna connected! RF transistors of every kind of transmitters are sensitive for proper
antenna match and can get damaged when working in unmatched conditions!
APRS Voyager incorporates only one RS-232 serial interface (contrary to PLXTracker or
PLXDigi), located on „RS-232 port 2” pins (port 1 is internally occupied by Bluetooth
interface).
If you wish to use a weather station, serial console, etc., you will need a different set of
serial cables than for PLXTracker or PLXDigi.
