Progress Tones
Knowing what the terminal is trying to tell you is very important when it does not do what
you think it should. The sound of the prompt will tell you a lot, if not exactly, what is
expected or what happened. The following table describes the various audible prompts of
the Series 2000 paging Terminal.
DIP Switches and Matrix Plugs
The central software communicates to each of the peripherals through a unique address or
port number. Each Trunk, Station, and Voice card must have its address or port DIP
switch configured uniquely otherwise a bus contention will occur. While usually not
damaging, the contention will only lead to confusion. Also refer to the “Switch Settings”
sections on page 87 and page 105 for information on the DIP switches on the telephone
trunk cards and the radio station cards.
Which station or trunk card receives what command or parameter is based on the setting of
its DIP switch, not which slot it is plugged into (from the viewpoint of the PC-BUS, all
slots are the same). It is possible to “fool” the system into thinking the station in slot 15 is
really in slot 16 by swapping the DIP switch settings between these two cards. This
example may result in pages destined for channel 2 go out on what used to be the station
for channel 1.
You must be careful when doing these tricks because the operating parameters for a
particular trunk or station may be different from others and not compatible with that
