TEST POINTS WITHIN THE SYSTEM
In addition to the internal system testing, it is also possible to connect a PC with
a COM port to the 9 pin RS-232 ”COMPACT” DSUB in the JB60CD electronic
unit. By using hyperterminal, many additional features can be checked.
It is also possible to see what is happening within the system by observing the
LEDs inside the JB60CD electronic unit. (See diagram on ”3) JB60CD Cabling
diagram” on page 50).
Here you can check if the sensor is operational.
LED Colour Description
LD 100 Green Flickers with each measurement.
LD 200 Green Flickers with data coming from the EML sensor.
LD 302 Red Flickers with data being sent to the sensor (not so
common).
LD 301 Green Flashes with each NMEA out transmission to navigation
system.
LD 300 Red Flashes with data arriving from the navigation systems.
NOTE: The LEDs will work even if the NMEA inputs are connected with the
wrong polarity. In the correct conguration, they are typically on and icker.
LOGGING DATA
No internal data logging is available, however, a diagnostics NMEA can be
logged on the standard NMEA port, or on the COMPACT plug in the electronic
unit (JB60CD).
