## System Design Overview

A typical LCD display system using the ALC-4096 comprises:

1. ALC-4096 controller board
2. LCD panel (V-by-One or eDP interface)
3. Backlight driver (if not built into the panel)
4. Panel signal cable (V-by-One or eDP)
5. Backlight cable(s)
6. OSD function control buttons or switch mount
7. Power supply (12VDC or 24VDC regulated)
8. Video input source (PC, media player, etc.)
9. Optional: IR sensor, ambient light sensor, status LED

## Step-by-Step Connection Procedure

1. **LCD panel and backlight:** Connect the inverter/backlight driver (if external) to the LCD panel's backlight connector.
2. **Panel signal cable:** Plug the V-by-One or eDP cable into J7. Ensure correct jumper settings (JC1–JC10) for the target panel — see the panel support table.
3. **Backlight driver:** Plug the backlight cable to CNB1 (and CNA1 if additional power is needed).
4. **OSD controls:** Plug the OSD switch mount cable to CNC1 on the controller.
5. **Status LED:** Plug a 3-way dual-color LED to LED1.
6. **IR sensor:** Plug a 3-way IR sensor to IR1 (optional).
7. **Jumpers:** Set JA3, JA7, JA8 for panel voltage. Set JB2 and JB3 for backlight control. See tables below.
8. **Video input:** Plug the HDMI, DisplayPort, or USB-C cable into the corresponding input connector.
9. **Power supply:** Plug 12VDC or 24VDC power into PP5. Matching cable: P/N 426013710-3 (1000mm).
10. **Power on:** Switch on the controller using the OSD switch mount.

## Jumper Settings

### Panel Voltage Selection (JA3, JA7, JA8)

**CAUTION:** Incorrect settings can damage the panel and controller.

#### With 12VDC Input (via PP5)

| Panel Voltage | JA3 | JA7 | JA8 |
|--------------|-----|-----|-----|
| 3.3V | 3V3 closed | 1-3 & 2-4 | OPEN |
| 5V | 5V closed | 1-3 & 2-4 | OPEN |
| 12V | OPEN | OPEN | 1-2 & 3-4 |

Max current for 3.3V, 5V = 4A.

#### With 24VDC Input (via PP5)

| Panel Voltage | JA3 | JA7 | JA8 |
|--------------|-----|-----|-----|
| 3.3V | 3V3 closed | 1-3 & 2-4 | OPEN |
| 5V | 5V closed | 1-2 & 3-4 | OPEN |
| 10V | 10V closed | 1-2 & 3-4 | OPEN |
| 12V | 12V closed | 1-2 & 3-4 | OPEN |
| 18V | 18V closed | 1-2 & 3-4 | OPEN |

Max current: 3.3V/5V = 4A; 10V/12V = 4A; 18V = 3A.

Note: JA3, JA7, and JA8 jumpers are marked in **red** on the board for visibility.

### Panel Output Power Pin Selection (JP11, JP12)

Controls which pins on J7 supply panel power.

| Power Output Pins on J7 | JP11 | JP12 |
|--------------------------|------|------|
| Pin 44–51 (panel pins 1–8) | 1-2 CLOSE | 1-2 CLOSE |
| Pin 48–51 only (panel pins 1–4) | 1-2 CLOSE | 1-2 OPEN |
| Pin 44–47 only (panel pins 5–8) | 1-2 OPEN | 1-2 CLOSE |
| No power output on these pins | 1-2 OPEN | 1-2 OPEN |

**CAUTION:** Incorrect settings can damage the panel and controller.

### Panel Timing Selection (JP3)

| JP3 Setting | Panel Model | Resolution | Interface |
|-------------|------------|------------|-----------|
| OPEN | Innolux M280DGJ-L30 | 3840×2160 | V-by-One |
| 1-2 closed | AU Optronics G270ZAN01.1 | 3840×2160 | V-by-One |
| 7-8 closed | BOE MV238QVM-N20 | 3840×2160 | eDP |

The controller sets preferred timing based on JP3 selection but can also support higher resolutions up to 4096×2160. Supports "Resolution default by EDID" for different resolution panels.

### Backlight Control Jumpers

| Jumper | Purpose | Settings |
|--------|---------|----------|
| JB1 | Backlight brightness voltage range | 1-2 closed = 5V max; 2-3 closed = 3.3V max |
| JB2 | Backlight on/off control — signal level | 2-3 = High = +5V; 1-2 = High = +3.3V; Open = High = open collector. **CAUTION:** Incorrect setting can damage inverter. |
| JB3 | Backlight on/off control — polarity | 1-2 = High = CCFT ON; 2-3 = Low = CCFT ON |
| JB5 | Backlight control type | 1-2 = VR/Digital switch mount; 3-4 = Analog 0–5V; 5-6 = PWM |
| JB7 | Backlight control voltage on CNB1 pin 4 (when JB5 = 1-2) | Open = OSD switch mount control (default); 1-2 = 0V; 2-3 = 3.3V/5V (controlled by JB1) |

### Panel Interface Jumpers (JC1–JC10)

| Setting | Meaning |
|---------|---------|
| 1-2 close | High |
| 2-3 close | Low / GND |
| Open | NC (No Connection) |

The NC state is subject to the panel specification's definition of NC.

### Other Jumpers

| Jumper | Purpose | Settings |
|--------|---------|----------|
| JP4 | Reserved | Default: Open |
| JP6 | Input power control | Short = External switch control; Open = Switch mount control |
| JP13 | RS-232 routing (rev 2x–30 only) | 1-2 closed = RS-232 via CN8; 2-3 closed = RS-232 via USB-C (P6) |
| JP14 | RS-232 routing (rev 2x–30 only) | 1-2 closed = RS-232 via CN8; 2-3 closed = RS-232 via USB-C (P6) |

Note: JP13 and JP14 were added in PCB revision 2x–30 (January 2026) as part of the USB-to-RS-232 circuit addition.

## Backlight / Inverter Connection Guide

There are three aspects to consider for inverter connection:

### Power
CNB1 pin 1 = Ground, pin 2 = +12V/+24VDC. Match to inverter specification.
For higher-power inverters, additional current can be taken from CNA1 pin 1.

### Enable
CNB1 pin 3 provides the enable/disable signal for VESA DPMS compliance. Set JB2 and JB3 to match the inverter's specification for enable pin voltage and polarity.

### Brightness Control
CNB1 pins 4 and 5 are available for VR-based brightness control. These connect to CNC1 pins 3, 4, and 5 for external potentiometer control.

**VR Circuit Design Notes:**
- R1 = 470Ω on board (between +5V and CNC1 pin 5)
- External potentiometer (RPOT) plugs into CNC1 pins 3, 4, 5
- Tie BVR_A (CNC1 pin 3) to GND (CNC1 pin 6) for use
- Example with 10KΩ pot: BVR_WIP = 5 × (Rbc / 10.47) volts, providing 0V to ~4.8V range

## Controller Mounting Guidelines

- Ensure at least 10 mm clearance above and 5 mm below the controller.
- Use insulation material between the PCB and any metal mounting plate.
- All mounting holes (3.4 mm diameter) are connected to the ground plane.
- Keep panel signal cables separated from inverter and backlight cables to prevent interference.
- Consider electrical insulation, grounding, EMI shielding, cable management, and heat/ventilation.
- Shielding may be required for regulatory emissions testing.

## Using the Controller Without Buttons

1. Set up and configure the controller/display system with buttons first.
2. Make all desired settings for color, tint, and image position, then power off.
3. Remove the control switches (12-way CNC1 cable).
4. Use a jumper to connect pins 1 and 2 on CNC1 — this fixes the board ON.
5. Configure inverter brightness as needed (may require a resistor, open circuit, or closed circuit depending on inverter).

## PC Settings

Recommended: 60Hz vertical refresh rate for optimal performance (no screen flicker). Refer to the supported graphics modes in the specifications file for all accepted input timings.
