Keyboard Connectors PS/2 Keyboard Connectors The PS/2 connectors provide an interface for the keyboard, mouse, and a variety of other pointing devices, such as trackballs, to the system. Consult the documentation that accompanies each input device for specific information concerning its use. 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. You can use an HP three-button mouse, a trackball, or other options as pointing devices with your workstation by using the serial ports or the HIL port. For instructions on using your particular pointing device, see the manual that came with 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) 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. Product Information 1-15
