guidelines for installation and preparation of a finished display solution.
Preparation: Before proceeding it is important to familiarize yourself with the parts making up the system and the various
connectors, mounting holes and general layout of the controller. As much as possible connectors have been labeled. Guides
to connectors and mounting holes are shown in the following relevant sections.
1. LCD Panel: This controller is designed for typical LVDS interface TFT panels with panel voltage 3.3V or 5V or 12V LVDS
interface. Due to the variation between manufacturers of signal timing and other panel characteristics factory setup and
confirmation should be obtained before connecting to a panel. (NOTE: Check panel power jumper settings before
connection)
2. Controller card: Handle the controller card with care as static charge may damage electronic components.
3. LVDS signal cable : In order to provide a clean signal it is recommended that LVDS signal cables are no longer than
46cm (18 inches). If loose wire cabling is utilized these can be made into a harness with cable ties. Care should be taken
when placing the cables to avoid signal interference. Additionally it may be necessary in some systems to add ferrite cores
to the cables to minimize signal noise.
4. Inverter: This will be required for the backlight of an LCD, some LCD panels have an inverter built in. As panels may have
1 or more backlight tubes and the power requirements for different panel models backlights may vary it is important to
match the inverter in order to obtain optimum performance. See page 20 for the Application notes “Inverter connection
section for more informations.
5. Inverter Cables: Different inverter models require different cables and different pin assignment. Make sure correct cable
pin out to match the inverter. Using wrong cable pin out may damage the inverter.
6. OSD switch mount controls: The following section discusses the controls required and the section on connectors
provides the detail. The controls are minimal: On/Off, Backlight Brightness (depends on inverter), OSD (5 momentary
buttons) analog VR type or (8 momentary buttons) digital type.
7. OSD switch mount controls cable: The cables to the function switches should be of suitable quality and length so that
impedance does not affect performance. Generally lengths up to 1 metre (3 feet) should be acceptable.
8. Controller status LED (Optional) : This LED indicates the controller status. The pin direction of the LED should be
corrected for right colour indication. Red colour stands for standby. Green colours stands for signal on. The status LED
is an optional part only, can be unconnected.

10. IR sensor: It is an optional part only, can be unconnected if not using IR remote control. See Appendix V for button
definition.
11. RS-232 control interface : Firmware upgrade and serial control via this interface port.
12. Analog VGA Input Cable: As this may affect regulatory emission test results and the quality of the signal to the controller,
a suitably shielded cable should be utilized.
13. Display Port Cable : Support single-link Display Port 1.1a. Plug the Display Port cable to the connector P4 on
the controller board.
14. HDMI input : Support HDMI 1.3 input up to 1080p/WUXGA resolution. Plug the HDMI cable to the connector P3 on

17. Audio Jack (Stereo) output from HDMI / Display Port / SDI input : This port support Stereo audio output from the HDMI
/ Display Port / SDI audio source inputted. The audio handling is same as HD-3000 where 2 channels (stereo) of
audio converted to HDMI output. Then the same HDMI audio handling as on the standard ALR-1920. It requires to select the
appropriate input source and select the audio port “SPEAKERS” via OSD menu under “Sound” > “Output” OSD menu page.
18. Audio output (Stereo) with amplication from HDMI / Display Port / SDI input : This port support Stereo audio output
from the HDMI / Display Port / SDI audio source inputted. The audio handling is same as HD-3000 where 2 channels (stereo) of
audio converted to HDMI output. Then the same HDMI audio handling as on the standard ALR-1920. It requires to select the
appropriate input source and select the audio port “SPEAKERS” via OSD menu under “Sound” > “Output” OSD menu page.
This audio output will disable when audio jack (J1) being plugged.
19. SPDIF Audio output : This port support SPDIF audio output from the HDMI / Display Port / SDI audio source inputted.
The audio handling is same as HD-3000 where 2 channels (stereo) of audio converted to HDMI output. Then the same HDMI
audio handling as on the standard ALR-1920. It requires to select the appropriate input source and select the audio port
“SPDIF” via OSD menu under “Sound” > “Output” OSD menu page.
20. Backlight status input : It only functions when connecting with the panel which support backlight status detection pin.
21. Power Input: 12VDC is required, this should be a regulated supply. Although the controller provides power regulation for
the LCD power this does not relate to the power supplied to the backlight inverter. If an unregulated power supply is provided to
an inverter any fluctuations in power may affect operation, performance and lifetime of the inverter and or backlight tubes.
• Power Safety: Note that although only 12VDC is supplied as ‘power-in’ a backlight inverter for panel backlighting
produces significantly higher voltages (the inverter does not connect to the ground plane). We strongly advise appropriate
insulation for all circuitry.
• EMI: Shielding will be required for passing certain regulatory emissions tests. Also the choice of external Controller to PC
signal cable can affect the result.
• Ground: The various PCB mounting holes are connected to the ground plane.
• Servicing: The board is not user serviceable or repairable. Warranty does not cover user error in connecting up to the
controller and is invalidated by unauthorized modification or repairs.
• Controller Mounting: It is recommended that a clearance of at least 10mm is provided above and 5mm below the
controller when mounted. Additionally consideration should be given to:
• Electrical insulation.
• Grounding.
• EMI shielding.
• Cable management. Note: It is important to keep panel signal cables apart from the inverter & backlight cables to
prevent signal interference.
• Heat & Ventilation: Heat generated from other sources, for example the backlight of a very high brightness panel may
generate significant heat which could adversely affect the controller.
• Other issues that may affect safety or performance.
• PC Graphics Output: A few guidelines:
• Signal quality is very important, if there is noise or instability in the PC graphics output this may result in visible noise
on the display.
• Refer to graphics modes table in specifications section for supported modes.
• Non-interlaced & interlaced video input is acceptable.
IMPORTANT: Please read the Application Notes section for more information.
