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):
LCD panel & Inverter: Connect the inverter (if it is not built-in the panel) to the CCFT lead connector of the LCD panel.
LVDS type panels: Plug the LVDS signal cable direct to J3. Insert the panel end of the cable to the LCD panel connector.
Inverter & Controller: Plug the inverter cable to CNB1 and CNA1 (if necessary). Plug another end to the connector on the inverter.
Function switch & Controller: Plug the OSD switch mount cable to CNC1 on the controller board and another end to the OSD switch mount.
LED 1 : Plug in a 3-way with dual colour LED to connector LED1 on the controller board for indicating the controller status.
IR & Controller: Plug in a 3-way with IR sensor to connector IR1 on the controller board.
Jumpers : Check all jumpers are set correctly. Details referring the connection diagram.
Jumpers & Inverter & Panel voltage: Particularly pay attention to the settings of JA3, JB1, JB2, JB3. JB2 & JB3 are used for inverter control (read
inverter specification and information on the jumper table to define the correct settings). JA3 is used for panel voltage input (read panel specification
and information on the jumper table to define the correct settings).
DVI cable : Plug the DVI cable to the connector DVI port 1 and 2 on the controller board.
Power supply & Controller: Plug the DC 12V power in to the connector PP2. You can consider to use DigitalView mating power cable P/N
426013800-3, 160mm.
Power on: Switch on the controller board and panel by using the OSD switch mount.
CAUTION: Never connect or disconnect parts of the display system when the system is powered up as this may cause serious damage.
Controller LED status (LED1 & LED1A) :

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.
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.

Remark :
# Assign SW1 position 4 to ON for connection to RM-DN5 (Firmware version : E1.12.10a) from HDMI port with the following changes :
- Add “Loading…” message on screen while startup and stay until the valid signal.
- Changed the default Auto Source Seek to Off
- Changed the IR key from "Display" key to "OSD Next" key for menu function
- Extend longer delay time approx. (4 secs) to detect signal for "No Signal" state
- Only DVI 1 input and disabled all other "Source" selections in OSD, IR hotkeys & RS-232 for RM-DN5 mode
