General Description

The LCP-100A Level Control Panel gives keypanel opera­tors direct access to the crosspoint gain adjustment feature
of the intercom system. It lets them adjust the individual
listen levels for 16 keypanel or expansion panel keys.

Upgrade EEPROM

The LCP-100A is compatible with all KP96, KP97, and
KP98-7 Keypanels. However, the supplied keypanel
EEPROM may need to be installed in some cases. Since the
EEPROM is different for each keypanel model, the
LCP-100A is packaged under three different catalog num­bers. See Table 1. The following paragraphs summarize the
keypanel model and EEPROM version identification, and
the procedure to replace the EEPROM. Note that the new
EEPROM changes the keypanel DIP switch functions as
summarized on page 2.

Keypanel EEPROM Version Identification

Keypanels with programming keypad: Tap key se­quence CLR-0-8. Then use the scroll up or down key to
locate the version number. It will be something like V82 or
V83G etc.

Note: If you are not able to determine the version with this
key sequence, or if the keypanel does not have a program­ming keypad, replace the EEPROM.

EEPROM Replacement

Table 2. KP96/97 DIP Switch Summary

Use normal precautions when handling static-sensitive de­vices.

1. Unplug the keypanel power cord.

2. Remove the screws from the top cover.

3. Locate the old EEPROM (U305). Observe the orienta­tion of the old EEPROM, then remove it and install the
new EEPROM in the same orientation.

4. Replace the top cover and reconnect power.

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 4

for address numbers.

Keypanel Baud Rate: Dip switch 8 sets the baud rate as
before.
