Sine/Cosine Output Configuration
Once you have finished the system installation,
configure the ADCU’s sine/cosine output for the
desired heading format and the correct voltages
for the external device.
1. Press the center MENU button on the ADCU
to access the onscreen menu (see Figure 58).
2. At “Setup display type?”, press NEXT until
the display shows “Setup data outputs?”
Then press ENTER and press YES to confirm.
3. At “Set sine-cos levels?”, press YES.
4. Now you need to select the desired heading
format. At “Sine cosine is”, press MAG to
select magnetic heading, or press TRUE to
select true heading. Then press ENTER.
5. At “Set Ref”, use the - and + buttons to set the
reference voltage (0 - 6.5 volts). Then press
ENTER.
TIP: If you do not know the correct reference voltage
for the external device, connect a voltmeter between
the ADCU’s reference terminal (#8) and the reference
terminal on the external device. Then simply adjust
the reference voltage on the ADCU until the voltmeter
indicates zero volts (0 VDC).
NOTE: If you are using a B&G 4-wire sine/cosine
output as a substitute for a Halcyon compass, set the
reference voltage to 3.5 volts.
6. At “Set Swing”, use the - and + buttons to set
the swing voltage (±0 - 6.5 volts). Then press
ENTER.

If you did not connect a GPS to the system,
only magnetic heading is available. If you
connected a ship’s gyro to the system, only
true heading is available.
