	Please order accessories separately as they are not included into device package.


Accessory and its description	Accessory connection schematic
1-Wire devices	Digital thermometer DS1820 and TTJ100 connection to FMB1YX
One of the implemented features on FMB1YX is 1-Wire® data protocol, which enables connection to devices such as thermometer (DS1820, DS18S20 and DS18B20) and I-Button DS1990A.
	TTJ sensor pinout

	I-Button DS1990A connection to FMB1YX

Fuel tank sensors	Fuel sensor connection to FMB1YX
A fuel tank level sensor which indicates the approximate fuel level on the driver's indicator panel exists in most cars. If the sensor returns analogue signal proportional to fuel level it can be connected to FMB1YX Analog input. After the connection to the tank fuel level sensor a calibration is needed because most fuel tank sensors are not linear. Calibration is performed by measuring voltage values resulting from the volume of fuel in tank.
Alarm buttons, door sensors etc.	Panic button connection to FMB1YX
Alarm buttons, door sensors, ignition, etc. have two output states: high or low. FMB1YX Digital inputs are used to detect these states.
Relays
In cases when sensor output signal is negative, an additional relay has to be installed to convert negative signal to positive.	Inverting relay connection

Immobilizer relay	Immobilizer relay
When connected as shown on the right hand side, FMB1YX disables engine starter when output is ON.
Automotive relay	Automotive relay pinout
An ordinary automotive relay is used to invert input signal or to immobilize engine starter. Note, that they are available as 12 V or 24 V.
