DC power supply
If the unit on the left (A) is turned on using the power button and is set as the Power Control
Master, it will output voltage on the Power Control bus to power on the other unit on the
right (B), the Radar Interface, and the SonicHub.
If the unit on the right (B) is set to Power Control Slave, it cannot be powered down using its
own power button, but can be set to standby.
If the unit on the left (A) is set to Power Control Master and is off, the unit on the right (B) can
be turned on using its own power button, but does not turn on any other devices.
To turn on all network devices from either the unit on the left (A) or the unit on the right (B),
both devices can be configured as Power Control Masters.
Ú Note:
If a unit has its power state controlled by another device (or ignition switch), it
cannot be totally powered down. It can however enter a standby state to save power.

External alarm

The external alarm can be a small piezo buzzer connected directly, or a horn siren connected
through a relay.
Alarms are configured globally in the system. That is, they can be configured on any one
networked multifunction device or instrument, and be seen, heard, and acknowledged from
all devices. Individual devices can also be configured to not sound their internal buzzer, but
still display the alarm information. For information about configuring alarms, refer to the
Alarms section in the Operator Manual.
For sirens that draw more than 1 Amp, use a relay.

Connect an external monitor
The 12" and 16" units incorporate HDMI technology and have a HDMI output which can be
connected to an external monitor to replicate the display at a remote location. The image is
shown on the external monitor at the units own native resolution, so the external monitor
should support the same resolution or be able to scale.
If a monitor of different resolution is connected, a dialog is displayed at power up which
allows you to Force HDMI output to the closest resolution it can output. This may not may
provide an optimal image on the monitor. The unit will need to restart to apply the change.
Ú Note:
An HDMI cable with a water tight HDMI connector should be used to connect to
the unit in exposed installations.
Ú Note:
While the HDMI standard does not state maximum cable length, signal may be
compromised on long runs. Only use Navico or other high quality HDMI certified cables.
