Care should be taken to make sure the compass is not situated too close

to the power supply, as it's accuracy may be affected by either the iron in

the mains transformer, or by magnetic field 'noise' from a switching power

supply. But this is unlikely as the A4032 will be mounted on a fixed

compass which should have been sited correctly.

Note that the output from the A4032 takes several seconds to stabilize

after power is applied; the time taken depends on the damping settings.

There is a command - see section 5 – which can be used to suppress the

output after power-up.

Note 1 For nominal 24V operation a 1W resistor of 330ohms should be

inserted in the supply wire.

The hardware on which the NMEA-0183 standard is based on is a balanced

serial protocol called RS422. This means that two wires are need for send

and two for receive.

Note that the GND wire is used for the current return path. This might be

shared with the NMEA- wire in some installations.
