ASSEMBLY NOTES

This controller is designed for monitor and custom projects with PAL, NTSC, SECAM video sources

over Composite or S-Video using 1600x1200 or 1400x1050 or 1366x768 or 1280x1024 or 1280x800

or 1280x768 x 1024x768 or 800x600 or 800x480 or 640x480 resolution TFT type LCD panels display

with TTL or LVDS inputs. The following provides some 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 or TTL single interface panels with panel

voltage 3.3V, 5V, 12V or 18V Due to the variation between manufacturers of panels signal timing

and other panel characteristics, factory setup and confirmation should be obtained before

connecting to a panel by reference to the original panel manufacturers panel specification and

download of the connection diagram from Digital View Controller Solution Generator at

www.digitalview.com

. (NOTE: Check panel power jumper settings before connection)

2. Controller: Handle the controller with care as static charge may damage electronic components.

Make sure correct jumper and dip switches settings to match the target LCD panel.

3. LCD signal cable (LVDS panel): In order to provide a clean signal it is recommended that LVDS

signal cables are no longer than 46cm (18 inches). If those 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

cable to minimize signal noise.

4. LCD signal cable (Single pixel TTL panel): In order to provide a clean signal it is recommended

that LCD signal cables should not longer than 33cm (13 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.

5. Inverter: This will be required for the backlight of an LCD, some LCD panels have an inverter

built in. As LCD panels may have 1 or more backlight tubes and the power requirements for

different panel backlights may vary it is important to match the inverter in order to obtain optimum

performance. See Application notes page 18 for more information on connection.

6. Inverter Cables: Different inverter models require different cables and different pin assignment.

Make sure correct cable pin out to match inverter. Using wrong cable pin out may damage the

inverter.

7. Function 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.

8. Function 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 meter (3 feet)

should be acceptable.
