2.8 POWER-UP AND OPERATIONAL CHECK

Plug in the ac power cords on the keypanel and any con-

nected expansion panels and level control panels. When

power is applied, all alphanumeric displays will first dis-

play asterisks (****) then dashes (----). After a few mo-

ments, the Talk key assignments will display. If no Talk

key assignments have yet been programmed, the displays

will continue to show dashes (----).

If the keypanel cannot establish data communications

with the intercom system, the alphanumeric displays will

continue to show asterisks (****). Check the data line

connections.

Several symptoms may occur if the logical keypanel

number is incorrectly set: 1) the keypanel may not display

the expected key assignments; 2) there may be no indica-

tion when there is an incoming call; 3) when a key is

pressed to talk, the destination may not hear the audio, or

may hear audio from a different intercom station; 4) the

displays may behave erratically. If any of these symptoms

occur, recheck the logical keypanel number DIP switches.

☞

Important! Always reset the keypanel after changing

the DIP switch settings. Do this by briefly removing

power to the keypanel.

2.9 KEYPANEL PROGRAMMING

If you previously configured the keypanel using the inter-

com system configuration software, it should be ready for

operation. Refer the station operator to the “Basic Opera-

tion” instructions in the KP96 / KP97 Operating Instruc-

tions Manual.

If the keypanel has not yet been configured you can do so

now. Run the ADAMedit or Zeus-edit configuration soft-

ware. By default, the configuration software starts up in

the “Keypanels / Ports” setup screen. For assistance with

keypanel setup, press the F1 key on the computer while

viewing that screen. Once you have configured the key-

panel as instructed and sent the changes to the intercom

system, the keypanel should be ready for operation. Refer

the station operator to the “Basic Operation” instructions

in the KP96 / KP97 Operating Instructions Manual.

This completes the standard installation procedures.

3 ELECTRICAL ADJUSTMENTS

3.1 INTERNAL JUMPERS

There are several internal jumpers which modify keypanel

operation. The jumpers are set for the following default

operations:

J201: The EXT LINE IN signal (KP-96-RC option only)

is muted when any Talk key is pressed. May be optionally

set for no mute.

J202: The speaker (or headphones) are muted by 15 dB

when any Talk key is pressed. May be optionally set to

full mute.

J203: Continuous sidetone. When using a headset, the

keypanel operators own voice will be heard at all times in

the headphones. May be optionally set for sidetone only

during talk.

J401: The microphone activates when any Talk key is

pressed. May be optionally set for continuous micro-

phone.

J402: Normal/test switch set for normal operation.

J403: The MIC PRE OUT signal (KP-96-RC option only)

is activated only when any Talk key is pressed. May be

optionally set for continuous operation.

J404-J406: The keypanel is configured for operation with

the standard dynamic, -70dB, 150-ohm gooseneck micro-

phone. May be optionally configured for other micro-

phone types.

To reset any of the jumpers, remove the top cover from

the keypanel. Locations of the jumpers are shown in Fig-

ure

8. The following paragraphs describe the alternative

settings for the jumpers.

3.1.1 J201 (EXTERNAL INPUT MUTING)

This jumper is only significant in keypanels that have the

KP-96-RC Rear Connector Plate option installed. When

pins 2 and 3 are shorted, a signal input at the EXT LINE

IN connector is muted when any Talk key is pressed.

When pins 1 and 2 are shorted, the signal is not muted

during Talk key activation.

3.1.2 J202 (SPEAKER/HDST MUTE)

When pins 1 and 2 are shorted, the speaker/headset signal

is fully muted when any Talk keys are pressed. When pins
