802.3 Network Connectors The 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. The workstation automatically selects the correct network setting. RS-232 Serial Input/Output Connector You can attach a variety of peripheral devices to the RS-232 Serial Input/Output (SIO) port on the workstation. These peripheral devices include printers, plotters, modems, and scanners. Consult the documentation that accompanies each peripheral device for specific information concerning its use. The SIO port is programmable. You can set functions such as bit rate, character length, parity, and stop bits. The SIO Port is used as an interface for serial asynchronous devices to the CPU. The port operates at up to a 19.2 K baud rate. Table 1-1 shows the SIO connector pin listings. The serial connector is a 9-pin D-sub connector. Signal names are those specified in the EIA RS-232 standard. Table 1-1.

Product Information
802.3 Network Connectors
The 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. The workstation automatically selects the correct network set-
ting.
RS–232 Serial Input/Output Connector
You can attach a variety of peripheral devices to the RS–232 Serial Input/Output
(SIO) port on the workstation. These peripheral devices include printers, plotters,
modems, and scanners. Consult the documentation that accompanies each peripheral
device for specific information concerning its use.
The SIO port is programmable. You can set functions such as bit rate, character
length, parity, and stop bits. The SIO Port is used as an interface for serial asynchro-
nous devices to the CPU. The port operates at up to a 19.2 K baud rate.
Table 1–1 shows the SIO connector pin listings. The serial connector is a 9–pin
D–sub connector. Signal names are those specified in the EIA RS–232 standard.
