INSTALLATION

Stand-Alone Data Terminals

Data terminals and computers may be connected to the system through ADUs or a Multiple Asynchronous Data Unit (MADU) without being linked to a voice terminal. Depending on the data terminal that they connect to, some ADUs may need supplementary power for proper operation. See Figures 2-42and 2-43.

ADU Connections

1.Unpack the ADU and examine for damage.

2.At the workstation, connect the ADU connector to the RS-232C receptacle of the terminal or computer. Always tighten the screws or other fasteners on this connection. If these connections are not properly fastened, the Data Line CP port may be falsely busied out.

3.Connect a modular cord between the ADU Wall jack and the modular wall jack.
