Test No. What it does What is wrong?
3 Write out 80 characters
to NMEA, ask user to
press if ok, or read back.
Manually check the output. If fail, try
to restart.
4 Write out 80 characters
to SENSOR, ask user to
press if ok, or read back.
Manually check the output. If fail, try
to restart.
5 - loop Turn on alarm - wait for
reset or loopback.
The user or loopback should reply to
the alarm by pressing the alarm reset,
(works only in test conguration).
6 - loop Pulse out sends a
pulse. If looped back to
dimming up, this test will
pass.
Fail implies the pulse out or dimming
up is not working. Try individually,
(works only in test conguration).
7 - loop Fitness out sends a
pulse. If looped to
dimming down, this test
will pass.
Fail implies the tness out or dimming
up is not working. Try individually,
(works only in test conguration).
8 - loop Test NMEA baud 4800,
38400, 115200. (Only
passes if looped to the
input).
Fail implies one of the speeds is not
working correctly. (Works only in test
conguration).
9 - loop Test sensor baud 4800,
38400, 115200. (Only
passes if looped to the
input).
Fail implies one of the speeds is not
working correctly.
10 Status of transducers
(Doppler only).
Tests 5 - 9 are designed to be smart by sending and recieving information at the
same time. They require loopback or the user to enter the expected reply. These
tests are primarily for factory use.
