The Program Panel consists of the following components.
1. LCD Controller board: Interfaces the video between the computer module and the LCD screen.
2. LCD User interface board: Sets the video input signal and adjusts the screen image for brightness,
contrast, etc. It also switches on/off the controller board and LCD screen. It has 1 LED light that
shows the state of the controller. This light is green and indicates the board is on. If you see a red
light, something is wrong and there most likely will be no video. This light should always be on when
power (12 VDC) is available. Press power button to see if light comes back on. See figure 5.4b and
5.4c.
3. LCD User Interface Cable: To connect between the LCD controller board and LCD user interface
board.

5. LCD Backlight Power Cable: To power the backlight on the LCD.
6. Overlay Interface Board: Responsible for sending and receiving signals to and from the programming
panel and computer module. This board is responsible for the overlay buttons. The beeper is also
found on this board. It also provides 12 VDC to the LCD module.
7. LCD Power Cable: Provides 12VDC, power to the LCD controller board.
8. LED indicators: The overlay interface board has a few LEDs that can be used for
troubleshooting. See figure 5.4e for location of LEDs on board.
a. D22 – each key press on overlay will cause this light to flash, except critical keys.
b. D23 – LED should always be on and this means power is getting to critical keys
c. D26 – LED should always be on and it shows we have 12 volts.
d. D25 – Txd (transmit exchange data) LED should blink on and off when a non-critical key is
pressed and relayed to computer module.
e. D24 – Rxd (receive exchange data) LED should blink on and off as confirmation from computer
module (acknowledgement or command from computer module) that a non-critical key was
pressed
