Figure 50. Connection diagram for fuel level sensor by RS-232 interface to the device 

 

Periodic data output mode must be enabled in the sensor and the network address and data transfer rate 

must coincide with those which are programmed in the device itself. 

 

Note: 

Some manufacturers of additional devices (FLS, CAN bus adapters, etc.) connected by the RS-232 interface 

change the physical meaning of the designations of the TX and RX interface lines. That is why in this connection 

these devices do not function, and it is required to reconnect them by swapping the RX and TX contacts. 

If there is any doubt which sensor line is Tx and which Rx , it is possible check this with a multimeter in the 

voltage measurement mode. The measured voltage on the sensor Tx line which is not connected to the terminal will 

be in the range from -5 to -12 V relative to the sensor supply “-”. On the Rx line, the voltage will be close to “0”. 

 

 

2.12 RS-485 interface connection 

The digital interface RS-485 is designed to connect devices transmitting and receiving information via this 

interface, for example, fuel level sensors, CAN bus adapter, tachographs, RFID, MODBUS-devices, etc. 

As a rule, the interface is used to connect  up to 16 digital fuel sensors. It is supposed to use digital LLS-

compatible sensors. 

The RS-485 + interface line of the device should be connected to the RS-485 + line of the sensor, usually 

designated as "A", and the RS-485 line of the device should be connected to the RS-485 line of the sensor, usually 

designated as "B". The RS-485 interface specifications practically do not limit the length of cables on a land vehicle 
(100m  or  more),  since  the  interface  is  a  differential  bus  and  is  well  protected  from  the  influence  of  external 

interference.
