NMEA Inputs (Position, Speed & Temp)
The iScan V90 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 V90 looks for the following NMEA
sentences for position, 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 V90 sends out the following NMEA 0183
sentences with the digital depth data.
