GalileoSky GLONASS/GPS v5.1 (223) User’s ManualGalileoSky Ltd Page 358.9 Connecting Garmin navigators supporting FMI protocolThe Terminal can serve as a gateway for Garmin FMI protocol packets transmission to the server and back.Garmin FMI protocol enables: drivers identification by code numbers (driver enters his/her number into a navigator, the number istransmitted to the server); driver status transmission to the server (driver selects his/her status on a navigator display); text messages exchange between Garmin navigator and the server; transmission of route end points from the server to the navigator (in this case, the navigatorcalculates optimal path to the set points and displays it on the map); control for speeding and informing the server about it; geofences transmission from the server to the navigator and displaying them.A description of protocol abilities can be found on http://www8.garmin.com/solutions/pnd .The Terminal only transmits the packets from the navigator to the server and back, so parsing the packetsshould be done at the server.To connect Garmin navigator:1. Purchase an interface Garmin FMI cable (for example, Garmin FMI 10), cable is to be chosenaccording to the navigator model. The cable has a mini-USB socket to connect to the navigator at oneend, and supply and RS232 interface contacts at another end.2. Connect RS232 interface contacts to the Terminal RS232 zero port; connect RX contact of the cableto the TXD contact of the Terminal; TX contact of the cable to the RXD contact of the Terminal; besure to connect GND RS232 contact of the cable to the GND contact of the Terminal.3. Connect cable power supply.4. Connect the cable to the navigator.5. Configure RS232 port in the Terminal to work with the navigator. It can be done by RS2320 5command or in the Configurator on Settings\Digital inputs tab.To make sure that the Terminal and the navigator connection works properly select messages from necessaryRS232 port in troubleshooting. If the connection is correct, the following messages will be displayed regularly:RS2320. Garmin FMI. Enable FMI.RS2320. Garmin FMI. ACK.If the connection is right, the navigator interface will change, the left-hand icon will take the form of a truck,it will give an access to messages sending and receiving functions.8.10 Connecting REP-500 electrical meterThe REP-500 is an electrical meter, which can be connected to the Terminal via RS232 interface. To connectthe REP-500, perform the following steps:1. Connect RXD, GND contacts of the Terminal to TX, Ground contacts of the REP-500correspondingly.2. Configure the RS232 port in the Terminal for operation with the meter. This can be performedusing the RS2320 10 command or in the Configurator on the Settings\Digital inputs tab.3. Set the meter readings transfer to the server with the help of MainPackBit 171,1 command. |
