GalileoSky GLONASS/GPS v5.1 (223) User’s ManualGalileoSky Ltd Page 298.3 Connecting digital fuel sensors using RS485 protocolThe order of connection:1. Connect RS485_A; RS485_B, GND sensor contacts to Terminal RS485_A; RS485_B, and GND contacts(section Contacts description).The sensor power supply is provided separately.2. 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.3. Make sure that the Terminal receives data from the sensor. It can be done in the Configurator on Devicetab.The Terminal can support up to 16 sensors at a time. The sensors should have addresses from 0 to 15correspondingly. If the Terminal receives no messages from the sensor for 18 seconds, the RS485 field valuewill be set to zero. In this way, it is possible to detect sensor disconnection or failure. Values from sensorswith the addresses from 4 to 15 and temperature data from sensors with the addresses from 0 to 15 arestored in the memory only by archive dynamic structure activation (FlashArchive command, section Servicecommands).
