2.4 Installing I/O Equipment
2.4.1 PS/2 keyboard and PS/2 mouse
The PPC-L106T provides a PS/2 keyboard connector that supports a PS/2
style keyboard and a 5-pin DIN keyboard extension cable. In most cases,
especially in embedded applications, a keyboard is not used. The standard
PC/AT BIOS will report an error or failure during power-on self-test
(POST) after a reset if the keyboard is not present. The BIOS standard
setup menu allows you to select* "All, But Keyboard" under the "Halt
On" selection. This allows no-keyboard operation in embedded system
applications without the system halting under POST. Note that the mouse
port on the PPC-L106T is a PS/2 mouse port.
2.4.2 Mic-in, line-out
The PPC is equipped with a high quality audio interface, which provides
16-bit CD quality recording and playback as well as OPL3 compatible
FM music. It is supported by all major operating systems and is com-
pletely compatible with Sound Blaster Pro.
The audio interface includes two jacks: microphone-in and line-out (See
Fig. 1-2).
2.4.3 External VGA
The PPC-L106T can be connected to an external CRT monitor. To con-
nect an external CRT monitor, connect the monitor's VGA cable to the
PPC-102's VGA port and connect the monitor's power cable to an AC
outlet. The PPC-L106T's external CRT display (VGA) connector is a
standard 15-pin D-SUB connector commonly used for VGA.
2.4.4 Four serial COM ports
Many available peripherals, such as a serial mouse or an optional touch-
screen, require connection to a serial port. When an optional touchscreen
is ordered with a PPC-L106T, it shares COM4, and COM4 is not avail-
able as a serial port.
Note: “All but keyboard” is the default setting.
