20 PCA-6157 User's Manual
Parallel port (CN3)
You normally use the parallel port to connect the card to a printer.
The PCA-6157 includes an on-board parallel port, accessed
through a 26-pin flat-cable connector, CN3. The CPU card comes
with an adapter cable so you can use a traditional DB-25 connector.
The cable has a 26-pin connector on one end and a DB-25 connec-
tor on the other, mounted on a retaining bracket. The bracket
installs at the end of an empty slot in your chassis, giving you
access to the connector.
SCSI-II internal connector (CN5)
The EBM3x-JA has a single 50-pin, dual in-line connector on the
board for internal SCSI devices. Connection of SCSI devices
requires special attention, especially when determining the last
drive on the SCSI chain. Refer to your device's operating manual
for detailed installation advice.
Keyboard connectors (J6, CN6)
The PCA-6157 board provides two keyboard connectors. A 5-pin
connector (J6) supports passive backplane applications. A second
6-pin mini-DIN connector (CN6) on the card mounting bracket
supports single-board-computer applications. The card comes with
an adapter to convert from the 6-pin mini-DIN connector to a
standard DIN connector.
PS/2 mouse connector (CN6)
The CN6 is a multi-function DIN connector. It can either be used for
a keyboard or a PS/2 mouse. JP6 sets the function for keyboard
input or for PS/2 mouse input. See "Jumper settings" in Chapter 1
to configure CN6 to PS/2 mouse input.
