• Manufacturer Part Number: 4171700XX-3
• Description: Display Modules & Development Tools SVH-1920+ CONTROLLER
• Manufacturer: Digital View Inc

Specifications of 4171700XX-3

• Lead Free Status / RoHS Status: Lead free / RoHS Compliant

18. DVI-D input cable : Plug the DVI cable to the connector P3 on the controller board
19. Analog RGB Input : As this may affect regulatory emission test results and the quality of the signal to the controller a
20. S-video input : Standard S-Video cables can be used. Reasonable quality cable should be used to avoid image quality
21. Composite input : Composite video input cable with BNC connector can be used. Reasonable quality cable should be
22. Auxiliary video input : This port provides Composite video 1 & 2, S-video 1 & 2, Component 1 & 2. The video input
23. Power Input: 12V/24VDC is required, this should be a regulated supply. The power rating is depending on the panel and
inverter used. Normally, power supply with 3.5Amp current output should enough for most of 4x CCFT panels. 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.
24. External panel power input : Allow to supply external power to the panel separately for max 3.3V (7A) or 5V (7A) or 12V

(5A) or 18V (3.5A) via PP4 power input connector.
Power output: Note the controller has an overall 3Amp current limit and the current available from the auxiliary power
output will be dependent on the power input and other system requirements.
Power Safety: Note that although only 12V / 24VDC is required 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:

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.
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.
