1.6.1 Jumper To Control Radar On/Off Operation
1.6.1.1 Radar Powered On all the time
Leave jumper located at top of Radar Junction Box mounted. This will keep pow-
ered On at all times.
1.6.1.2 Radar Powered On/Off Controlled by an External Switch
The two remaining small leads, the Green wire and the Blue wire, connect to the
On/Off control switch. The On/Off control switch does not switch the main power
leads to the scanner unit, but it does provide a signal that controls DC power
inside the scanner unit.
1.6.1.3 Radar Power On/Off Controlled by the Chart Plotter Software
Remove jumper. Connect the EXTERNAL ALARM signal of the chart plotter to
TERMINAL Strip C, Terminal ALR (see connection tables).
Setting up the chart plotter I/O in the following mode:
[MENU] + "Advanced Options" + [ENTER] + "Input/Output" + [ENTER] +
"External Signal" + [ENTER] + "External Alarm" + [ENTER]
Power the Radar On/Off directly from the Radar page:
[MENU] + "POWER" + [ENTER] + "ON"/"OFF" + [ENTER]
1.6.2 Alternative Power Connection
You can feed the Power supply to the Radar directly.
1.6.2.1 Power Connections
♦
Route the large black and white wires directly to the power panel. No
switch is required.
♦
Connect the large black wire to the battery negative (—) terminal of
the power panel.
♦
Connect the large white wire (with the in-line fuse) to the battery posi-
tive (+) terminal of the power panel (12 to 24 VDC nominal). Do not
omit the in-line fuse unless a dedicated and fused terminal is available.
If so, install a 5 Amp fuse. If you are installing a SWR 10 open scanner
Radar, it is important to also connect the Red (+) to positive power
terminal, and Blue (-) to negative power terminal, as this provides
power to scanner motor.
This completes the installation of your Radar scanner unit.
Please proceed with setting up the data ports in your chart plotter, following the
instructions below.
1.7 SOFTWARE CONFIGURATION
First you have to install the Radar. Refer to the following paragraphs to configure
the chart plotter to operate with the Radar.
1.7.1 I/O Setup
Setting up the chart plotter I/O depends upon which port is used to connect the
Radar. If you use the connecting cable supplied with the Radar, the Port2 is the
default setting. In this case follow the procedure:
[MENU] + "Advanced Options" + [ENTER] + "Input/Output" + [ENTER] +
"Port 2 Input" + [ENTER] + "Radar" + [ENTER]
