Setting the Parameter Switches
The caller ID device has two banks of parameter-controlling Dual In-Line Pin (DIP) switches located on its front
panel.
Setting Switch S1
Switches S1–1 through S1–8 select the signalling protocol of the RS232 Out connector and asssist in matching the
caller ID device’s signals with that of the communications system.
Switches S1–1 through S1–8 are all factory set to OFF. Ensure that these switches remain OFF unless you are
stacking multiple caller ID devices together. If you are stacking multiple units together, leave S1–1 through S1–6
and S1–8 OFF but set S1–7 ON.
Setting Switch S2
Switches S2–1 through S2–5 set the baud rate, data bits, and parity. Switches S2–6, S2–7, and S2–8 set the unit
address for each caller ID device when you stack multiple devices together.
