Warning! All warnings in Section 2.3.1 apply here.
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-103 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.
The parallel port interrupt channel is designated to be IRQ7 or
IRQ5. The BIOS standard setup menu allows selection of
"378H/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-103 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 Key-
board" 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-
103 is a PS/2 mouse port.
Notes: (1) The 40-pin connector is a secondary channel.
(2) That part of the secondary IDE's cable which is below
45 cm in length is incorporated in the accessory box.
