For normal operation, Northstar recommends that you leave
both beacon frequency and baud rate at the AUTO setting.
Generally, you'll use automatic mode for everything except
specialized applications.
To choose automatic mode:
1. At the RECEIVER INFORMATION screen, press the
CURSOR PAD to highlight the BEACON FREQ field, then
press the EDIT key.
2. Press the CURSOR pad left to highlight the AUTO field,
then press the ACCEPT key (or CANCEL to leave the
option unchanged).
Manual tuning
You can override the receiver's selection of automatic
differential stations at any time. Under manual control, you
manually set the differential frequency and baud rate to tune
in a particular differential transmitter. In manual mode, the
differential receiver outputs DGPS corrections only from the
selected station. Although the need for manual operation is
rare, it is easily accessed at the RECEIVER INFORMATION
screen. Here, you can set the differential frequency to any
value between 283.5kHz and 325kHz. You can set the baud
rate to any of the four standard rates: 25 bps, 50 bps, 100 bps,
or 200 bps.
To choose manual mode:
1. At the RECEIVER INFORMATION screen, press the
CURSOR PAD to highlight the BEACON FREQ field, then
press the EDIT DATA key.
The cursor defaults to the MAN field.
2. Use the KEYPAD to enter the desired frequency.
3. When done, press the ACCEPT key (or CANCEL to leave
the option unchanged).
Manually setting baud rate
It is strongly recommended that you leave the beacon baud
rate setting at AUTO. To manually set the baud rate for the
selected differential frequency:
