Before making any connections study the manuals for fuel level sensors supplied by the sensor
manufacturers. Pay attention to the supply voltage range of the sensors and peculiarities of their
configuration. Some sensors require external supply voltage stabilization. If you have any doubts on
making connections or configuration, consult the representative of the sensor manufacturer or your
regional TechnoKom dealer.

At the present time AutoGRAPH on-board controller supports connection of TKLS fuel
level sensors produced by TechnoKom Ltd. and other sensors supporting LLS and Modbus
protocols via RS-485.
There is AGHIP (AutoGRAPH Hardware Interface Protocol) protocol intended for AutoGRAPH
controller to operate with AutoGRAPH peripherals as well as TKLS fuel level sensors. Enabled
in TKLS sensors, this protocol allows reception of additional data along with fuel level, e.g.
sensor’s error codes, an inclination angle of a fuel tank (vehicle) and etc.
Also LLS and Modbus protocols can be used to receive data from TKLS sensors.
Given below is a connection diagram of TKLS fuel level sensor to RS-485-1 bus of AutoGRAPH
controller. This diagram is applicable for third-party fuel level sensors connecting to the
controller via RS-485 bus.
Be careful not to cross the «A» and «B» wires, otherwise the device connected to the tracker
may operate incorrectly.
