The cable connectors, terminating resistor, and cable switch for a network station are placed in a separate box which can be unplugged as a unit from the station, so that the station itself can be physically removed from a multi-drop network without interrupting any other stations on the network. Present display terminals 10 have a non-removable system-interface panel 11 containing connectors 12 for connecting cables 13 between each other and a host computer in a multi-drop configuration, as shown in Fig. 1. Other functions are sometimes packaged within this panel, such as a switch 14 for connecting a terminating resistor in the last terminal on the cable.
