Overview<\/h1>\n

The M7 GX series of GPS transponders may be directly connected to a Garmin Oregon 450<\/strong>. When connected, the Garmin display map will show the location of the vehicle it is in PLUS the location of all other M7 transponders within radio range.\u00a0 This unique feature allows one to quickly, easily, and inexpensively, make a mobile AVL system for tracking cars, trucks, race cars, construction equipment, or any thing Raveon\u2019s M7 GX transponder may be installed on.<\/p>\n

The Garmin Oregon 450 has a built-in interfaces for a \u201cNMEA 0183? devices, which is another way of saying that they can connect to other devices using a serial cable.\u00a0\u00a0 The NMEA 0183 is an RS232 serial connection that typically operates at 4800 baud.\u00a0 It is used to exchange way point and other information between displays, GPS devices, and transponders.<\/p>\n

When Raveon\u2019s M7 GX transponder is connected to the Oregon using the NMEA 0183 connection, the M7 transponder can put icons on the screen of the Garmin display.\u00a0 As the transponder received updated positions from other vehicles, it updates the position of the icons on the Garmin display.<\/p>\n

How NMEA 0183 works<\/h2>\n

Here is how their NMEA 0183 interface works:<\/p>\n

NMEA 0183 Cable Connections<\/p>\n

NMEA 0183 is a standard communications format for marine electronic equipment. For example, an autopilot can connect to the NMEA interface of a GPS and receive positioning information.\u00a0 The GPS can exchange information with any device that transmits or receives NMEA 0183 data. See the following diagram for general wiring connections. Read your product\u2019s owner\u2019s manual for specific wiring information.<\/p>\n

NMEA 0183 Wiring\u00a0 (Data cable)<\/p>\n

The Garmin Oregon 450 uses the yellow wire to transmit, the white wire to receive and the Black and green wire for ground. <\/em><\/p>\n

The M7 DB9 Serial Connector<\/h2>\n

The 9-pin serial I\/O connector on the M7 is a female 9-p D-sub miniature connector having the following pins configuration.<\/p>\n

Wiring the DB9<\/h2>\n

The Oregon\u2019s \u201cData Cable\u201d must be connected to the M7 transponder.\u00a0 This connection will allow the M7 to put icons on the screen of the Oregon display, showing the location of other tracked vehicles.\u00a0 The Raveon M7 GPS transponder uses a 9-pin \u201cDB9? connector to connect to the Oregon.\u00a0 Solder the Oregon data cable wires onto a DB9 connector and plug the DB9 into the M7 transponder as shown below:<\/p>\n

\"\"<\/a><\/a><\/p>\n

The white wire<\/strong> goes to pin two of the DB9, the yellow wire<\/strong> to pin 3, the black <\/strong>and green wires <\/strong>get twisted together and both go <\/strong>to pin 5, and the red wire<\/strong> goes to pin 9 of the DB9. It is recommended that you keep the fuse on the red wire when setting up the DB9 connector.<\/p>\n

Configuring the M7 GX Transponder<\/h2>\n

Raveon has a designed the M7 GX transponder to work with Garmin Oregon Display or any other NMEA 0183 display that can accept the \u201c$GPWPL\u201d NMEA message.\u00a0\u00a0\u00a0The $GPWPL is an industry standard message that the Garmin displays and many other GPS displays interpret as a way point command.\u00a0 The M7 GX outputs this $GPWPL message to put icons on the screen of the Garmin, and to move the\u00a0icons around on its screen.<\/p>\n

To configure the M7 transponder to output the $GPWPL message, set the M7 GX to GPS mode 2.\u00a0 To do this, put it into the configuration mode by send the +++ into the serial port.\u00a0 The M7 will respond with an OK.\u00a0 Type GPS 4 and press enter to put it into GPS 4 mode.\u00a0 GPS 4 is the mode that causes the M7 GX to output $GPWPL messages whenever it receives a status\/position message over the air.<\/p>\n
