ITF Keyboard Connector The HP HIL connector provides an interface for the ITF keyboard to the system. Consult the documentation that accompanies each input device for specific information concerning its use. 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 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 J200 workstation. Peripheral devices include printers, plotters, modems, and scanners. Consult the documentation that accompanies each pointing or peripheral device for specific information 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. 1-15
