Telex BKP-4, TKP-4 AND WKP-4

Closed: keypanel cannot answer incoming calls to

TIF-951.

Description: The keypanel can answer incoming tele-

phone calls received by an RTS Model TIF-951 Tele-

phone Interface. However, it cannot perform any other

telephone operations. For example, it cannot force the

TIF-951 to hang up at the end of a call. In many cases, the

TIF-951 can detect a hang up at the far end of the line and

then hang up itself. However, this may not always be the

case in all phone systems. In such cases you may wish to

completely disable keypanel operation with the TIF-951.

DIP Switch 4

Open: Default setting. Use a panel mic (connected to the

Mic connector) to talk and use the speaker to listen. Or,

use a headset (connected to Headset connector) to talk

and listen.

Closed: Special Applications. Use a dynamic mic (con-

nected to the Headset connector) with the speaker. Or, use

headphones (connected to the Headset connector) with a

panel mic (connected to the Mic connector).

Description: Typically, you will use the keypanel either

with a panel microphone and a speaker or with a headset.

The special applications setting is seldom used.

DIP Switch 5

Open: Default setting. Latching turned on.

Closed: Latching turned off.

Description: An intercom key can always be turned on for

momentary conversation by pressing and holding the key

during the conversation. There is also an electronic latch-

ing feature that lets you tap intercom keys to turn them on

or off. This permits convenient hands-free conversation.

However it can also result in a talk circuit being left on

unintentionally. For example, a key that talks to a public

address system could be accidentally left on. Or an IFB

key (a type of key assignment that is often used by a di-

rector or producer to give instructions to a listener, such

as a news anchor during a television broadcast) could ac-

cidentally be left on, causing confusion for the IFB lis-

tener. To prevent such accidents, the latching feature can

be turned off.

DIP Switches 6-8

Not used. Leave Open.

2.4.2 Address Switch

☞In Zeus, ADAM CS, and ADAM intercom systems,

intercom ports are arranged in groups of 8 or 12

intercom ports. Within each group, each keypanel

keypanel is uniquely identified by its Address switch

setting.

The Address switch has a white pointer which points to

the current switch setting. Determine the proper setting as

follows:

Important! Always reset the keypanel after changing the

Address switch setting. Do this by briefly removing

power to the keypanel.

Zeus Intercom Systems:Intercom port connectors on the

Zeus back panel are arranged in three groups of eight in-

tercom ports. For each group, intercom port connectors

are labeled ID 1, ID 2, etc. When you connect a keypanel

keypanel to Zeus, set the keypanel Address switch to

match the corresponding ID number on the Zeus back

panel. Note that address switch settings 0, and 9 through F

are not used.

ADAM CS Intercom Systems:Each Audio I/O card

contains 1 group of 8 intercom ports. However, the

method of breaking out the groups depends on the type of

connectors on the back panel. To determine the keypanel

Address switch setting, use the planning worksheets in the

ADAM CS Installation Manual. These are located near

the back of the Installation Manual:

•ADAM CS with RJ12 or DB-9 back panel: You

can determine the keypanel address from the

worksheets in either of two ways: 1) If you know the

port number that a keypanel will be connected to,

look up the port number in the worksheet, then read

across to the appropriate logical keypanel number for

that port number. Use that number to set the keypanel

Address switch. 2) If you know the connector number

(on the back of the ADAM CS frame) that the

keypanel will be connected to, look up that connector

number in the worksheet, then read across to the

appropriate logical keypanel number. Use that

number to set the keypanel Address switch. Note

that address switch settings 0, and 9 through F are not

used.
