3.5.10 Matrix Keyboard port (KEY & LED)
GF_VEDO HL uses the KEY & LED port to communicate with series TF keyboards.
It uses a high-speed full-duplex synchronous serial interface (SPI) with proprietary communication protocol.
This allows scanning of the key matrix and control of off/on status of LEDs on the keyboard.
The connector is an 8-pin RJ45 without LED, which allows keyboard communication and power.
Signal assignment is shown in Table 15.
Cable length can be a maximum of 1 metre.
3.5.11 Mouse and Keyboard PS2 port
The PS2 port connects the GF_VEDO HL to keyboards and mice conforming to PS2 standard.
Two mini-DIN 6-pin female connectors are used (green: Mouse, violet: Keyboard).
Signal assignment is shown in Tables 16 and Table 17.
