A2.2 Mouse & Keyboard Interfaces
The physical PS-2 mouse & keyboard interface is brought out on this 8HP front-panel. Connector
pinout and description are provided in Figure A2.2 and Table A2.2 respectively.
Note:
If the mouse and keyboard ports are
used in rear I/O applications then they
should not be used from the front-
panel. Communicating from both
mouse and keyboard sources is physi-
cally possible but is not recommended!
