Set-up suggestions

When the device is fixed in place and connected it can be calibrated as

described above. Choose a calm day and a region of water where there

are no currents. Set the boat turning to left or right at a slow rate and fix

the wheel or tiller. Then, when the turning is steadily under way, press

the auto-calibrate button and watch the LED.

When calibration is completed the boat can be on its way and the next

task is to set North. This is best done by identifying transits on a chart

and heading the boat on the transit. Again, this should be done in the

same conditions so that the heading can be lined up on the transit and

maintained while the set-zero button is pressed.

NMEA-0183 commands

The compass can be configured by sending various proprietary sentences

to its NMEA-0183 input. Once configured, the compass will remember

those settings every time it is powered up.

Response:

When any of the input sentences are received the A5023 and A5024 will

reply with an 'acknowledge' output sentence of the format:

$PATC,HCHDG,ACK<CR><LF>

Unless the command results in response which contains data.
