Warning! Make sure that the red wire corresponds to pin 1 on the
connectors.
2.4.3 Parallel port connection
Normally a parallel port is used to connect a printer to a system. The
PPC-102 includes one multimode (ECP/EPP/SPP) parallel port with a
25-pin D-sub connector.
The parallel port is designated as LPT1 and can be disabled or changed to
LPT2 or LPT3 in the system BIOS setup.
The parallel port interrupt channel is designated to be IRQ7 or IRQ5. The
BIOS standard setup menu allows selection of "278H/IRQ5, 378H/IRQ7,
3BCH/IRQ7".
ECP/EPP DMA channels (DMA1 and DMA3) can be selected via the
BIOS setup.
2.4.4 PS/2 keyboard and PS/2 mouse
The PPC-102 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-102 is a PS/2 mouse port.
* Note: "All, But keyboard" is the default setting.
2.4.5 Mic-in, line-in, speaker out
The PPC-102 contains an ESS 1868 chipset, which is a single,
mixed-signal audio chip designed into the PPC-102. It provides
high-quality stereo sound and FM music synthesis, and is compatible with
Sound Blaster Pro version 3.01 voice and music functions. The PPC-102
includes Mic-in, Line-in and Speaker out capabilities as part of its I/O
adapter capabilities. These capabilities are provided under the Plug and
Play (PnP) standard, which allows PnP configuration for your equipment.
