Device installation (LX45)

Central unit is only mounted in inside of the vehicle, it can not be installed in the engine chamber, next to the cabin, or in the area of exposure to direct external conditions. Central unit must be hidden (for example, under the upholstery), as well as protected from moisture exposure. Device must be fastened in a stable position to avoid random twitches and displacements (suspension on cables is strictly prohibited). Central unit must be mounted horizontally. Precise orientation is of particular importance to flawless operation of the system, since the device is equipped with acceleration sensors recording the data which directly affects the results obtained.

LX45 pinout

To insert a SIM card, connect the internal battery open the box by lifting plastic holders from both sides.

Power supply

Power supply of central unit has to be connected directly from the vehicle’s battery, using 3A fuse.

Ground wire

Ground wire should be connected to the vehicle body. A reliable electrical contact with the body must be ensured, wire has to be bolted.

Ignition input (combustion lock status)

Connect a wire of the vehicle where voltage is present only when ignition is activated to IN5.

Universal digital inputs (optional)

Universal Digital inputs (IN2; IN3; IN4; IN5) are intended to collect data from remote devices.

Analog inputs (optional)

Analog inputs are intended to collect data from remote devices by measuring voltage. ADC3, ADC4, range 0-31V.

RS232 TX & RS232 RX

Minimum voltage: -15V

Maximum voltage: +15V

EIA 485 A & EIA 485B

Minimum voltage: -7V

Maximum voltage: +12V

Steps to install the central unit:

1. Open the housing by gently lifting the plastic holders on each side and remove the PCB from it. o Use thin screwdriver to lift up the plastic holders in order not to brake them.
2. Locate the SIM holder and following the printed picture on the PCB insert the SIM card.
3. Place the PCB to the housing and close it.
4. Use plastic fastening straps to fix device in a stable position (units housing has four holes, for straps to go through and fasten them to the body of the vehicle).
5. Connect power supply;
6. Connect ignition wire to a digital input (usually IN5);
7. Connect array;
8. Connect fuel level sensor(s) to the RS-232 or RS-485 interface;

• To read FLS sensor based on RS232, calibrate your sensor and connect to the device using Blue and Purple wires on device side.

Note, that RX of device goes to TX of sensor, as well as TX goes to RX. At once, can be connected only one RS232 based device with baud rate of 19200 bps.

• To read FLS sensor based on RS485, calibrate your sensor and connect to the device using Green and Green/black wires on device side.

Note, that A of device goes to A of sensor, as well as B goes to B. At once, can be connected up to 14 RS485 based devices. Connection should be made in parallel way, also should be set different addresses while calibrating FLS. Baud rate must be set to 19200 bps.

9. Connect other devices (optional).
