NB2DSK01 - PS2 Mouse and Keyboard Ports

The NB2DSK01 provides two standard PS/2 interfaces, for connection of an IBM PS/2-compatible mouse and keyboard. Each port is implemented using a 6-way mini-DIN (Female) connector and is directly connected to two daughter board FPGA I/O pins, providing CLOCK and bidirectional DATA lines respectively.

Location on Board

The 6-way mini-DIN connectors used to provide the PS/2 Mouse port (designated J6 with green colored jack) and the PS/2 Keyboard port (designated J5 with purple colored jack) are located on the component side of the board, between the USB interface and the 5V power connectors.

Schematic Reference

The PS/2 interface circuitry can be found on the following sheets of the motherboard schematics:

• Sheet 52 (PC_PS2.SchDoc, entitled PC PS2)

• Sheet 53 (CON_PS2KEYBOARD_MINIDIN6F.SchDoc, entitled PS2 Keyboard Connector)

• Sheet 54 (CON_PS2MOUSE_MINIDIN6F.SchDoc, entitled PS2 Mouse Connector).

Design Interface Component

Table 1 summarizes the available design interface components that can be placed from the FPGA NB2DSK01 Port-Plugin.IntLib, to access and use the on-board PS/2 Mouse and PS/2 Keyboard ports, respectively.
