Backlight; Nmea0183 Echo; Alarm Output - Vetus EC Manuel D'utilisation Et Instructions D'installation

5.3.1 Backlight

The backlight input is an auto sense input
which means that the applied voltage is
relative to the battery voltage. If the bat-
tery voltage is 12V the backlight setting
is maximum when the applied voltage to
pin 2 is 12V. If the battery voltage is 24V
and the applied voltage to pin 2 is 12V the
brightness will be dimmed.
PIN 2: Backlight dim input (0 to 12V or 0 to
24V, auto sense)
See chapter 8 Options.
5.3.2 NMEA0183 echo
The NMEA echo pin is used for connecting
other devices who also need the NMEA
messages from the compass sensor.
PIN 8: NMEA0183 output, in combination
with GND pin 7
See chapter 8 Options.
5.3.3 Alarm output
The Alarm output is used for connect-
ing an external warning device such as a
buzzer. If more than 100 mA is needed a
small relay should be used.
