will be adequate to reach to the source of DC power. The 3 pin watertight
connector plugs into the rear panel receptacle in the lower left comer of
the unit marked DC 12-40V.
The power leads should normally be routed to the ship’s DC power
distribution panel on larger boats. The unit requires 5 amps of current; is
fused at 10 amps. So connection to a 10 amp or (maximum of) 15 amp circuit
breaker is recommended. On smaller vessels, the power leads may be
connected directly to the main battery isolation switch or breaker. For best
noise immunity from the other shipboard electronics avoid grouping the
unit’s power connections together with the radar, radio, or other navaids,
such as loran or GPS on the same circuit breaker. The power leads should
be separated as much as possible from other devices.
Although the
unit’s
power consumption is approximately50 watts, if the
power cable leads need to be extended more than 10 feet, the gauge of the
wire leads should be increased accordingly to minimize line losses. For
runs of
feet # 12 AWG is recommended.
Confirm the power leads are connected to the correct terminal polarity!
The WHITE wire should be connected to the Positive (+ source terminal;
the
BLACK wire
should be connected to the Negative (-) source terminal.
If the power leads are accidentally reversed, the rear panel fuse will blow.
If this happens, recheck the polarity of the power cord connections with a
voltmeter (VOM) and, if necessary, reverse the leads for a proper polarity
connection. Replace the fuse.
Data Input/Outputs
The has one Data Input port and one Data Output port available
at the 6 pin connector marked located on the rear panel (next to
the Power connector). When an external navaid is connected to the Data
Input port, the
can recognize the NMEA or JRC serial
formats:
NMEA 0182 format, only the Latitude and Longitude of
the ship’s position will be supplied to the echo sounder to operate the
plotting mode.
NMEA 0183 format, the sentences GLL, GTD,
APB, VTG, BWC, RMA, RMC, and RMB can be read by the unit.
