HP Parallel I/O Connector
The 25-pin HP Parallel I/O interface uses Centronics interface proto-
cols to support peripheral devices such as printers and plotters. Con-
sult the documentation that accompanies each peripheral device for
specific information concerning its use.
802.3 Network Connectors
Your workstation has built-in ThickNet LAN AUI and TP (Twisted
Pair) connectors for the 802.3 (ETHERNET) network. Connections to
ThinLAN networks require an external transceiver. Your workstation
will automatically select the correct network setting.
RS-232C Serial Input/Output Connector
You can attach a variety of pointing devices (such as a mouse or
trackball), or peripheral devices to the RS-232C Serial Input/Output
(SIO) ports on the J280 workstation. Peripheral devices include print-
ers, plotters, modems, and scanners. Consult the documentation that
accompanies each pointing or peripheral device for specific informa-
tion concerning its use.
The SIO ports are programmable. You can set functions such as bit
rate, character length, parity, and stop bits. The SIO Ports are used as
an interface for serial asynchronous devices to the CPU. The ports
operate at up to a 19.2 K baud rate.
Table 1–2 shows the SIO connector pin listings. The serial connectors
are 9-pin D-sub connectors. Signal names are those specified in the
EIA RS-232 standard.
