Connecting LLS to FM5500
In order to use LLS fuel counter the 01.00.01 Firmware version or later is needed which can
be obtained from Teltonika or a representative. Firmware is updated by using cable update
method (see chapter 4 for more information).
The LLS fuel sensor can be connected to the FM5500 device via RS232 or RS485 interface.
Port 1 has both RS485 and RS232 interface.When LLS is connected via RS485, RS232 line can be
used for other purposes. Port 2 can use only RS-232 protocol. The FM5500-LLS fuel sensor
connection schemes are shown below.
*Teltonika is not responsible for any changes made by the manufacturer, which is not declared in fuel level
sensor documentation.
Port on FM55 side.
