Interphase 180 - NMEA Inputs (Position, Speed & Temp)

31
NMEA Inputs (Position, Speed & Temp)
The iScan 180 has two independent serial NMEA input
ports. One can be used to connect to a source of lat/lon
position and speed data (i.e., GPS), and the other can be
connected to a source of temperature and speed data.
An external GPS should be connected between the White
(+) and Green(-) wires in the power and I/O cable from the
Quick Disconnect Mount, and the Temperature and Speed
source should be connected between the Brown(+) and
Green(-) wires.
The iScan 180 looks for the following NMEA 0183 V2.0
sentences to get information on positon, speed and
temperature.
GLL ( Lat/Lon Postion)
VTG (Speed over the ground)
MTW (Temperature)
NMEA Depth Output
NMEA 0183 depth information is sent out on the Yellow
(+) and Green(-) wires. See the sketch at right showing
the wiring for the NMEA output port.
The iScan 180 sends out the following NMEA 0183 V2.0
sentences with the digital depth data..
