2. Digital switching mode
Digital switching means that you can turn some loads (digital switching channels) ON or OFF via
chartplotter or software. For example, using a virtual button on the chart plotter screen you can turn on
navigation lights or a bilge pump.
In digital switching mode, Device allows you to turn ON and OFF any of its 28 internal "virtual" digital
switching channels from the chart plotter or from other digital switching equipment or software. Channels
can be managed by NMEA 2000 digital switching messages (PGN 127501 and 127502) or with proprietary
CZone messages (supported in most modern chart plotters, see the Section VI).
In NMEA 2000, digital switching devices are identified on the network by their bank number (can be
changed with YD:BANK command, see Section V). Channels on devices with the same bank number will be
turned ON or OFF synchronously by external equipment, this allows simultaneous activation of multiple
Alarm Buttons with the same function installed at different places on the boat.
Temperature, pressure and humidity sensors from Yacht Devices can be set up to turn target digital
switching equipment channels ON or OFF when the measured value is too high or too low. For example,
the Digital Thermometer can trigger an alarm on the Alarm Button when the temperature in an engine
room or live well is too high.
Our NMEA 2000 Wi-Fi Gateway or NMEA 2000 Wi-Fi Router allows to manage digital switching channels
via web browser; it can be used to trigger an alarm remotely, say, from the cockpit, to notify the crew or
scare a thief over the Internet.
Device also can receive and process proprietary Raymarine Seatalk Alarm messages (PGN 65288). Usually,
such messages are sent by Raymarine chart plotters. By default, processing of SeaTalk Alarms is disabled,
you can enable them using command YD:ALARM (see the Section V).
3. Engine alarm mode
In this mode, Device will activate various alarms upon reception of engine and transmission warnings (via
PGNs 127489 and 127493). You can also set up the Device to activate alarms on abnormal values of engine
revolutions, coolant temperature, oil and boost pressure. For example, you can program Device to activate
an alarm when engine revolutions exceed 3000 RPM for 30 seconds or more.
