it.

HP Parallel I/O Connector

The 25-pin HP Parallel I/O interface uses Centronics interface protocols to support
peripheral devices such as printers and plotters. Consult the documentation that
accompanies each peripheral device for specific information concerning its use.

802.3 Network Connectors

The J200 workstation has built-in ThickNet LAN AUI and TP (Twisted Pair)
connectors for the 802.3 (ETHERNET) or 10 BaseT/100 BaseT (J2240 only)
network. Connections to ThinLAN networks require an external transceiver. The
workstation automatically selects the correct network setting.

RS-232 Serial Input/Output Connectors

There are a variety of pointing devices (mouse or trackball) or peripheral devices that
can attach to the RS-232 Serial Input/Output (SIO) ports on this workstation.
Peripheral devices include printers, plotters, modems, and scanners. Consult the
documentation that accompanies each peripheral device for specific information
concerning its use.
The SIO ports are programmable, allowing functions such as bit rate, character
length, parity, and stop bits to be set. The SIO Ports are used as interfaces for serial
asynchronous devices to the CPU. The ports operates at up to a 19.2 K baud rate.
Table 1–6 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.
