5.1.2. IR LED BOARD
IR LED boards are used to emit high intensity Infra-Red light focused to the
Front and Rear Target plates.
IR LEDs are loaded on each board. The IR light falls on the Target plate and
the reflected image will be captured by the Camera.
A group of Blue LEDs are loaded on this board, which are used to indicate the
direction during the wheel alignment sequence.
Red LEDs are provided in each Board to function as Stop indicator during
Wheel Runout (PPR) & Caster swing sequence
The boards have Control signal connector (10Pin FRC) and Power connector
(3Pin Phoenix). The Power connector carries Gnd, IR volts (8V-9.5V) and
+12V. The IR volt is the input for IR LEDs. +12V is used for Blue & Red LEDs.

5.1.3. LED DRIVER BOARD & HUB BOARD
USB2.0 LED DRIVER BOARD & HUB BOARD
The LED Driver board & Hub board has Microcontroller which is interfaced
with the PC through built-in USB HUB module to receive the commands from
the PC and then controls the IR LED board intensity based on the requirement
and drives the Blue & Red LEDs whenever the alignment program requires.
The Input supply voltage is +12Volts from SMPS. This board has two
adjustable Regulators for IR LED board.
The Trimmer pot (TR1) is to be adjusted to get 9V on Pin2 of connector (CN6)
for the Left IR LED board intensity to cover seven metre distance from the Left
Camera to rear Target plate.
The Trimmer pot (TR2) is to be adjusted to get 9V on Pin2 of connector (CN5)
for the Right IR LED board intensity to cover seven metre distance from the
Right Camera to rear Target plate.
Three ports are used in the USB hub module for Camera-LH, Camera-RH and
the Microcontroller (integrated). The USB cable from the PC is connected to
the input of Hub module.
USB3.0 HUB BOARD
USB3.0 Hub board is used to connect all the cameras to this board and
transfer the data to the PC.
It has one up stream USB3.0 type B Female connector which receives the
data from the PC. There are three downstream connectors USB3.0 Type-A
Female to connect the USB3.0 cameras. Both Top and Bottom Cameras are
connected in two USB3.0 ports. One port is available as spare port. If any one
of the port is not working, this free port can be used. The Hub board is stacked
over the LED driver Board using board to board connector.
