GalileoSky GLONASS/GPS v5.1 (223) User’s ManualGalileoSky Ltd Page 288.2 Connecting digital fuel sensors using RS232 protocolThe order of connection:1. Connect RXD, TXD and GND sensor contacts to Terminal TXD0, RTD0 and GND contacts (section Contactsdescription).Attention! The Terminal and sensor grounds must be connected!The sensor power supply is provided separately.2. Set for the RS232 Terminal channel an option to receive relative fuel level or frequency from the sensor. Itcan be done by sending RS2320 command (section Digital inputs settings) or through the Configurator onSettings/Digital inputs tab. RS232 Terminal channel is set to receive relative fuel level by default.3. If you need to filter bursts of fuel, adjust filter length by DFILTER command (section Digital inputs settings)or in the Configurator on Settings/Digital inputs tab. Temperature is saved only by archive dynamic structureactivation (FlashArchive command, section Service commands).4. Set transfer of received data to the server by MAINPACK command (section Server exchange protocolsettings) or in the Configurator on Settings/Protocol tab. These data transmission is on by default.5. Reset the Terminal by Reset command or in the Configurator on Device tab.6. Make sure that the Terminal receives data from the sensor. It may be done in the Configurator on Devicetab.If the Terminal receives no messages from the sensor for 18 seconds, the RS232 field value will come to zero.In this way, it is possible to detect sensor disconnection or failure. |
