Connection diagrams of AutoGRAPH-
INFO-TFT
This section covers connection procedures of AutoGRAPH-INFO-TFT
• Power supply connection
• Digital inputs / outputs connection
• Connection to the AutoGRAPH onboard controller.
• RS-485 bus connection.
• Connection of a loudspeaker and PTT switch.
Full capacity of AutoGRAPH-INFO-TFT is provided when it is connected to the AutoGRAPH
on-board controller. AutoGRAPH-INFO-TFT can be connected to any AutoGRAPH on-board
controller which is equipped with RS-485 bus.
Connection to the AutoGRAPH controller allows AutoGRAPH-INFO-TFT to send data to
server and exchange SMS with a dispatcher.
Before connecting AutoGRAPH-INFO-TFT to AutoGRAPH controller, GPS/GLONASS and
GSM antennas must be connected to the controller according the instructions given in the
User Manual of the AutoGRAPH controller.
POWER SUPPLY CONNECTION
The AutoGRAPH-INFO-TFT is connected to the power supply source through the primary
interface cable supplied with the device. Also the AutoGRAPH-INFO-TFT is supplied with a
fuse intended to provide a short circuit protection of power supply driver. The fuse holder is
installed on a wire ring, which should be cut before installation.
When making connections, pay special attention to the safety rules stipulated by the
regulations for motor vehicle repair procedures. All connections should be properly isolated
and securely connected. If the wire is too short, it can be spliced with a wire of at least 0.5
mm2 cross section (20 AWG or thicker).
The power supply input of the AutoGRAPH-INFO-TFT is rated for the vehicle system operating
voltage of 10-60 V DC. The pin 1 of the device Power connector must be connected to 12 or
24 V of vehicle operating voltage through a fuse rated for at least 1 A.

The fuse should be placed as close as possible to the point where the AutoGRAPH-INFO-TFT is
connected to the vehicle power system.
IMPORTANT
The scheme of power supply connection to the AutoGRAPH-INFO-TFT depends on the
power supply connection to AutoGRAPH controller. So power can be fed to the display either
before or after the vehicle’s battery disconnecting switch:

DIGITAL INPUT 1 («+» DIGITAL INPUT 1 AND «-» DIGITAL INPUT 1)
AutoGRAPH-INFO-TFT is equipped with a digital input which logic of operation depends on
how an external device is connected to the input (Input 1).
Depending on the connection diagram the Input 1 may operate as active low input or active
high one.
The input is able to show change of the input state and intended to connect various dry
contact sensors, e.g. door limit switches or any button.

CONNECTION OF HIGH-IMPEDANCE DIGITAL INPUT
AutoGRAPH-INFO-TFT is equipped with a digital high-impedance input: pin 5 on the Power
connector.
High-impedance active high digital input is intended to connect a device with a voltage output
to the display, e.g. a voltage output temperature sensor.
The high-impedance input has two states:
• logical “1” – when the input voltage is greater than 7 V;
• logical “0” – when the input voltage is lower than 3 V.
If the high-impedance input is open-circuit it shall denote logical “0”.
The input resistance of the high-impedance input is 1 mega-ohm (1MΩ).
The cut-off frequency of the input low-pass lter is 5,000 Hz.
DIGITAL INPUTS 2 AND 3
AUTOGRAPH-INFO-TFT is equipped with two active high digital inputs: pin 3 and pin 7 on
the Power connector.
Active high digital input has two states:
• logical «1», when the input is powered by supply voltage. This state is considered to be
active.
• logical «0», when the input is connected to the ground or open-circuit.
It should be noted that all voltage levels of active high digital inputs under 5 V will be
considered to be logical zero (‘ground’), while all voltage levels above 6 V shall be considered to
be logical «1» (active). If the input is open-circuit it shall denote logical «0» .

LOUDSPEAKER CONNECTION
AutoGRAPH-INFO-TFT is equipped with two audio outputs intended to connect loudspeakers
to the display, e.g. loudspeakers installed in the passenger compartment.
Pins intended for connecting the loudspeakers are arranged on the 4-pin loudspeaker
interface connector: pin 15 and pin 17 are intended for connection of left loudspeaker, pin 16
and pin 18 – for right loudspeaker.
Minimum load resistance must be at least 4 Ohm. Maximum load resistance must not exceed
16 Ohm.

RS-485 BUS
RS-485 is one of the most commonly used industrial standards of communication. A network
based on an RS-485 interface consists of transceivers connected with twisted pair wires. All
devices are connected to one twisted pair in the same manner: non-inverting outputs (A) to
one wire and inverting outputs (B) to another wire.
AutoGRAPH-INFO-TFT is equipped with 3 RS-485 buses, each of them is intended for
connection of specic devices. This can be taken into account when making the connection
because if incompatible device is connected to RS-485 bus, proper operation of that device
is not provided.
Given below is description of RS-485 buses assignment:
• RS-485-1 bus is intended for connection of display boards supported by AutoGRAPH-
INFO-TFT.
• RS-485-2 is intended for connection of photo cameras.
• RS-485-3 is intended for connection of the AutoGRAPH onboard controller and sensors
supporting LLS protocol.
RS-485 interface pins are arranged on the 4-pin RS-485 connector.
Detailed information on how to congure AutoGRAPH-INFO-TFT for operation with display
boards, photo cameras, the AutoGRAPH onboard controller, and fuel level sensors via RS-
485 bus is given in following sections of this document.

NOTE
Connection to PC
Some cases may require connection of the AutoGRAPH-INFO-TFT device to a personal
computer (PC) or a laptop, e.g. for conguration using the DisplayCongure application.
The AutoGRAPH-INFO-TFT is connected to a PC using standard AM – USB mini B 5pin
Data-cable.
To connect the AutoGRAPH-INFO-TFT to a PC:
• Disconnect the device from vehicle power supply and external devices.
• Connect the device to PC using Data-cable.
• If the required drivers are installed, the system will automatically identify the connected
device. If the drivers are not installed, install them following the steps specied in the «Drivers
installation» section. Now the device is ready to operate with the applications.
