Nmea Inputs (Gps, Temp) / Nmea Depth Output - Interphase Color Twinscope Operation Manual

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