Operation 25
This section covers a variety of G12 operating parameters and options, including
system setup, power-up, command format, serial port configuration, receiver
settings and status, the satellite search algorithm, position modes, altitude hold
definition, the ionospheric model, NMEA outputs, raw data outputs, differential
operation, the photogrammetry option, the pulse-per-second option, and other
options.
If you use equipment other than Magellan-supplied with the G12, it must comply
with hardware specifications as described in the “Hardware Description” section
on page 3.
Before applying power, connect any controller devices or data logging equipment
to the input/output pins on the J301 connector. Applying power to the power input
pins on the J301 connector starts G12 operation. Cutting the flow of power to the
power input pins on connector J301 stops G12 operation.
Power-Up
Upon power-up, the status LED (D302 on the G12 OEM board) lights red and
green and then continues to flash red, indicating the unit is on, but position has not
yet been computed. When the G12 locks on to a satellite, the status LED flashes
CAUTION
To avoid damaging the G12, always connect or disconnect the power
wiring to 30-pin connector J301 before turning on the power supply.
