CONNECTION & OPERATION
CAUTION
: Never connect or disconnect parts of the display system when the system is powered up as this may cause serious
damage.
CONNECTION
Connection and usage is quite straight forward (it is useful to have the relevant connection diagram available at this time):
1. LCD panel & Inverter:
Connect the inverter (if it is not built-in the panel) to the CCFT lead connector of the LCD panel.
2.
LVDS type panel
s
:
The controller board has the built-in LVDS transmitter driver. Plug the LVDS cable to J3. Insert the
panel end of the cable the LCD panel connector.
4.
Inverter & Controller:
Plug the inverter cable to CNB1 and CNA1 on PR-1200/PR-2400 (if necessary). Plug another end
to the connector on the inverter.
5.
Function switch & Controller:
Plug the OSD switch mount cable to CNC1 on the controller board and another to the
OSD switch mount.
6.
Interconnection cables :
Panel power input cable P/N 426101100-3 and controller power in and backlight control cable
P/N 426101200-3 are required to connect between SGX-1920L and PR-1200/PR-2400.
7.
LED & Controller:
Plug in a 3-way with dual colour LED to connector LED1 on the controller board.
8.
IR & Controller:
Plug in a 3-way with IR sensor to connector IR1 on the controller board.
9.
Jumpers & Switches:
Check all jumpers and switches (SW3, SW4) are set correctly. Details referring the connection
diagram (a separate document) or the jumpers and switches setting table (in the following section).
10. Jumpers & Inverter & Panel voltage:
Particularly pay attention to the settings of JA3 & JA6 on SGX-1920L, JB2 and JB3
on PR-1200/PR-2400. JB2 & JB3 are used for inverter control (read inverter specification and information on the jumper
table to define the correct settings). JA3 & JA6 is used for panel voltage input (read panel specification and information on
the jumper table to define the correct settings).
11. Input signal cable :
Plug the HDMI input signal to J1 or VGA & Composite signal to CNV3, CNV4 on the controller board.
12. Power supply & Controller:
Plug the DC 12V power to PR-1200 P/N 416019610-3 on PP2/PP3 & DC 24V power to PR-
2400 P/N 416019510-3 on PP2/PP3. You can consider to use DigitalView mating power cable P/N 426013800-3, 160mm
for PP2/PP3 connection.

.
Audio Board :
The Audio Add-on Board P/N 416940020-3 is only operate under 12VDC power input environment.
Suggested to use the matching audio cable P/N 426454500-3 for connection to audio add-on board P/N 416940020-3 and
PR-1200/-2400)
General:
•
If you are using supplied cables & accessories, ensure they are correct for the model of panel and controller.
•
If you are making your own cables & connectors refer carefully to both the panel & inverter specifications and the section
in this manual, “Connectors, Pinouts & Jumpers” to ensure the correct pin to pin wiring.
PC SETTINGS
The controller has been designed to take a very wide range of input signals however to optimize the PC’s graphics performance
we recommend choosing 60Hz vertical refresh rate – this will not cause screen flicker.
OPERATION
Once the system has been connected and switched on there are a number of functions available to adjust the display
image as summarized in the following sections. The settings chosen will be saved for each mode independently.
