Connections to ThinLAN networks require an external transceiver. The workstation automatically selects the correct network setting. USB Connectors The two USB (Universal Serial Bus) Series A connectors on the rear panel of the J5000 and J7000 workstations provide interfaces for the standard keyboard and mouse only. Either connector can be used for either the keyboard or the mouse. See the "Keyboard and Mouse" section on page 34 for a description of these input devices. Also consult the documentation that accompanies the keyboard and the mouse for specific information concerning the use of each device. Parallel 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 parallel peripheral device for specific information concerning its use. 26 Chapter 1
