► Product Overview

This keyboard control board is the original core signal adapter component for the Philips IntelliVue X3 monitor. Both models are seamlessly compatible with X3 devices, eliminating the need for model-specific replacements. Built with a green, high-density printed circuit board (PCB), the board integrates key detection circuitry, a signal processing chip, and a foolproof interface module, featuring a compact layout and robust protection. Visually, the board has precise mounting holes along the edges, a black ribbon cable connector in the center, and a QR code and model label on the bottom. Its compact size allows for precise insertion into the monitor's internal keyboard module slot. As the signal hub between the keyboard keys and the device's motherboard, it converts key presses into electrical signals and transmits them to the motherboard. It can directly replace a faulty old board without additional adjustments, quickly restoring the monitor's key operation and interactive functions. It is a crucial component ensuring smooth clinical operation.

► Main Functions

1. Key Signal Conversion and Processing: The core receives the weak electrical signals generated by keyboard key presses, 

preprocesses them through a built-in debouncing circuit and encoding chip to filter out accidental touch interference, 

and then accurately transmits them to the monitor's mainboard, ensuring that every key press command is accurately 

recognized.

2. Two-Way Signal Interaction: It both uploads key operation signals to the mainboard and receives commands from the 

mainboard for backlight control, operation feedback, etc., enabling functions such as key backlight illumination and 

operation feedback prompts in conjunction with the keyboard module.
