Figure 4-2 Connection Example of GPS Receiver
The GPS18xPC is a GPS module receiver. And it interfaces via a 9-pin D-Sub RS-232C serial port.
Refer to the wiring example using commonly-available DB-9 connector (male), and a cable with
3-conductor plug (Kenwood service part: E30-3400-15). Power is sourced from the 12VDC supplied
from a vehicle cigarette lighter socket. Because there is no screen, you cannot use the Waypoint
function.
Figure 4-3 Cable Connection Example (Garmin GPS18xPC)
The AvMap G5 comes with a Kenwood-ready cable and exclusive APRS interface built right into the
panel. You can watch APRS activity on the AvMap G5 screen without having a PC. It also can be
configured to navigate to your favorite APRS station.
The GPS receiver used must be based on NMEA 0183 format (http://www.nmea.org
).
The following RS-232C signal levels are allowed for using the TH-D72A/E:
• Low level: - 15 V to 0.5 V
• High level: +3.0 V to +15 V
You cannot use a GPS receiver with a USB connector.
