==Installation==
Before installation, make sure UL202 Ultrasonic Fuel Level Sensor is not powered ON. The RED and BLACK wires of User Interface line have to be connected to the Power Supply of the vehicle with RED wire connecting the positive role and BLACK wire connecting the ground. UL202 has RS232 serial port output: 
[[image:FMB640_RS232.png]]

==FMB640 configuration==
In order to configurate FMB640 to read UL202 Fuel Sensor information, COM1/2 port have to be selected as “UL202-2 Fuel Sensor”. Default baudrate is 9600. 
[[image:Ul_rs232.png]]
 
To receive UL202 Fuel Sensor information to configured server, Ultrasonic UL202 Fuel level and status have to be enabled in “I/O” section. 
[[image:Ul_io.png]]

==RS232 connection==
RS232 Communication: The Yellow wire (TX) is connected with PIN6 RS232 Rx and the Blue wire (RX) is connected with PIN5 RS232 Tx. The Black wire (GND) connected to Teltonika GNSS device ground.

==Installation steps==
# Requirements: main body of the sensor, probe, extension line, user interface line, couplingagent, 2.8-meter long hose clamp, sand paper and glue. 
# The customers need to prepare: 12V power supply, isolating tape, and duster cloth and paper tissue (used to wipe off grease dirt). 
# Before installing on the vehicle, ensure that the vehicle is at horizontal ground and the fuel tank is placed on frame horizontally. 
# The installation area of probe should avoid the fuel filler, fuel outlet, fuel return pipe, fuel float and baffle. 
# Select the flat part at fuel tank bottom or close to the central area as possible. 
# For circular oil tank, in addition to avoiding the barrier, the tangent plane closest to the ground should be selected. [[image:Ulll.png|300px]]
# Connect the main body of the sensor with user interface line, extension line, probe connection line. 
# Power ON control box. The fuel level is displayed 000.0 at the moment. 
# Apply coupling agent on probe surface. Press the probe at the selected installation position. The display of the main body displays the currently measured liquid level. 
# Hold down “Key 1 for more than 8 seconds and release it to enter input state of total fuel tank height. F030 in the figure below means that total height of the fuel tank is 30cm. Press “Key 2” to increase and press “Key 3” to decrease. Hold down “key 1” for 8 second to confirm the parameters. 
# After total height of the fuel tank is put properly, it enters the input state for current liquid level of the oil tank. E030 in the figure below means that current liquid level height is 30cm. Press “key 2” to increase and press “key 3” to decrease. [[image:Ell2.png|300px]]
# After the current liquid level of the oil tank is put properly, press “key 1” more than 8 seconds to enter the automatic adjustment state of oil tank signal strength. 
## At the moment, you may observe whether the displayed height on the display screen is consistent with actual fuel level (for example, the predicted level is about 300mm and displayed 285.2mm). 
## If the display screen displays 000.0 or the displayed height is quite different from the actual condition, the probe may be moved slightly or grind the fuel tank wall more. In addition, the buzzer in the equipment sounds continuously (if the buzzer sounds on and off or does not sound, it needs to seek the installation point or grind the fuel tank wall more until the buzzer does not sound). 
## Hold down “key 1" for more than 8 seconds to complete search and test of installation point.
