DeskCoderTM UR5HC418 AT / PS/2 - Compatible Keyboard Encoder HID & SYSTEM MANAGEMENT PRODUCTS, KEYCODERTM FAMILY DESCRIPTION The DeskCoderTM keyboard encoder functions as a versatile, low-power desktop keyboard encoder, while providing two bi-directional channels for communication with a BIOS-compatible system as well as any optional keyboard-compatible devices, such as a 101/102/104 desktop keyboard, OCR, barcode reader, etc. The DeskCoderTM fully supports the IBM standard keyboard communication protocol; each key press generates one of the scan codes designated in the IBM Technical Reference Manuals. The keyboard encoder handles the scanning, debounce, and encoding of 128 keys organized on an 8 x 16 matrix.
