Status LED
The LED on the connector panel provides valuable information on the status
of your DSM250. The LED blinks green while the module is operating
normally. If the unit detects a problem, the LED blinks amber to indicate a
warning or red for an error. The number of times the LED blinks is a code
representing the nature of the problem. For multiple warnings/errors, the
codes are given in sequence with a 1.5 second pause between strings.
The following table shows the various LED status codes and their meanings.
1
After 30 seconds of no
hsb 2
activity, the DSM250 enters Standby mode: No sonar pings are
emitted and no warnings are output on the LED.
Instead, the LED blinks green once every 10 seconds.
For example, if the Transducer Sense fails and
hsb
2
is not detected, the unit
blinks amber once, pauses 1.5 secs, blinks amber twice 0.5 secs apart, pause
1.5 secs, and then repeats the sequence until the problems are resolved or (for
some warnings/errors) up to 10 minutes elapse.
