KP96/97 Keypanel DIP Switch Functions after
EEPROM Replacement
Refer to Table
and the following descriptions.
☞
Important: Any time you change the DIP switch
settings you must turn the power off-then-on to reset.
Combinations of Expansion and Level Control Panels:
Dip switches 1 and 2 select the various allowable combi-
nations of expansion panels and level control panels that
can be connected to the keypanel.
Winking On / Off: DIP switch 3 turns the winking feature
on or off. When winking is on, the LED in each listen key
will wink when the talk key directly beneath it is on. This
provides a visual reminder of any active talk paths. For
some people, this may be distracting and the feature may
be turned off.
Keypanel Address: DIP switches 4-7 set the keypanel
address as before. See Table
for address numbers.
Keypanel Baud Rate: Dip switch 8 sets the baud rate as
before.
