4.10.3 Keyboard and PS/2 mouse connector
The CPC-2245N provides a keyboard and PS2 mouse interface through a 40-pin FPC connector (CN4) for connection of PS/2 keyboard and PS/2 mouse.
In most cases, especially in embedded applications, a keyboard is not used. The standard PC/AT BIOS will report an error or fail during power-on self-test (POST) after a reset if the keyboard is not present. The CPC-2245N's BIOS "Standard CMOS Features" allows you to select "Halt on" under the "All, but keyboard" or "All, but disk/key" selection. This allows no-keyboard operation in embed- ded system applications without the system halting under POST (power on self test).
