CONFIGURATION SWITCHES
Important! If you change any configuration switch settings during operation, you must momentarily turn off
power to reset.
DIP Switches
DIP Switch 1
Open: Default setting. All incoming calls appear in the call waiting display (if present).
Closed: Only calls for unassigned callers appear in the call waiting display (if present).
Description: Any intercom key that is already assigned to talk/listen to a specific intercom port
will always provide an LED flash for incoming calls from that port. If a designation strip is used
the keypanel operator can identify the caller from the designation strip. Optionally, the caller's
name can also display in the call waiting window. If you don't want this to happen, set DIP switch
1 to Close.
NOTE The above description applies only to assigned keys. Whenever there is an incoming call, and
there is no key assigned to the caller, that caller's name will always display in the call waiting
window.
DIP Switch 2
Open: Default setting. 15 second flash after incoming call is received.
Closed: LED flash until caller releases key.
Description: Whenever there is an incoming call and there is a talk key assigned to the caller, the
talk LED next to that key will flash. The flash can be set for 15 second timeout, or until the
caller's talk key is released.
DIP Switch 3
Open: Default setting. Cannot answer incoming calls to TIF-951 or TIF-2000.
Closed: TIF operation enabled.
Description: The unit can answer incoming telephone calls received by an RTS model TIF-951 or
TIF-2000 telephone interface. However, it cannot perform any other telephone operations. For
example: It cannot force the TIF to hang-up at the end of a call. In many cases, the TIF units 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 leave TIF operation disabled.
DIP Switch 4
Open: Default setting. Use a panel mic (connected to the Mic connector) to talk and use the speaker
(connected to Speaker connector for MKP-4) to listen. Or, use a headset (connected to Headset connector)
to talk and listen.
Closed: Special Applications. Use a dynamic mic (connected to the Headset connector) with the
speaker (connected to Speaker connector for MKP-4). 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.

2-4 User Instructions MKP-4, BKP-4, WKP-4, TKP-4, and MKP12 Keypanels
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 latching 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 director or producer to give instructions to a listener, such as a
news anchor during a television broadcast) could accidentally be left on, causing confusion for
the IFB listener. To prevent such accidents, the latching feature can be turned off. the latching
feature can also be turned on/off using ADAMedit or ZEUSedit software. Please refer to the
respective help file to use this feature.
DIP Switch 6
Open: Default setting. 6-bit English protocol enabled.
Closed: 8-bit Katakana protocol enabled.
Description: Selects the type of protocol used for communications. The default 6-bit protocol
allows the display of English language characters. The optional 8-bit Katakana protocol allows
the display of Japanese language characters.
DIP Switch 7
Open: Default setting. Half-duplex communication disabled.
Closed: Half-duplex communication enabled.
Description: When closed the audio flowing in and out of the keypanel is in half-duplex
mode.When a talk key is depressed, audio coming in to the speaker/headphone is cut off.
Incoming audio is enabled as soon as the talk key is released. This application is seldom used.
DIP Switch 8
Open: Default setting for MKP-4, BKP-4, TKP-4 and WKP-4. Map keys as xKP-4 series.
Closed: Default setting for MKP-12. Map keys as MKP-12.
Description: When closed the four keys normally present in the xKP-4 series are remapped to the
left most keys on the MKP-12 keypanel. If this switch is in the open position on an MKP-12 the
keys will appear as 9-12 on the panel. This function corrects mapping differences between the
xKP-4 series, MKP-12, and how they relate to ZEUSedit.
Address Switch
NOTE In Zeus, ADAM CS, and ADAM intercom systems, intercom ports are arranged in groups of 8.
Within each group, each 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.
NOTE Address switch settings 0, and 9 through F are not used in ZEUS, ADAM, or ADAM CS systems.

Zeus Intercom Systems: Intercom port connectors on the Zeus back panel are arranged in three
groups of eight intercom ports. For each group, intercom port connectors are labeled ID 1, ID 2,
etc. When you connect a keypanel to Zeus, set the keypanel Address switch to match the
corresponding ID number on the Zeus back panel.
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:
1If 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.
2If 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.
ADAM CS frame with 50-pin Telco back panel: You can determine the keypanel address
from the worksheet in either of two ways:
1If 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.
2If you know the connector numbers and pin numbers that the keypanel will be connected to,
look up these numbers in the worksheet, then read across to the appropriate logical keypanel
number. Use that number to set the keypanel Address switch.
ADAM Intercom Systems: Each Audio I/O contains 1 group of 8 intercom ports per card.
However, the individual intercom ports may be broken out using various types of breakout panels
or punch blocks, and groups may not be easily identified. It may be easier to set the keypanel
Address switch using the actual intercom port numbers. To do this, refer to Table 2.1. Locate the
intercom port number to which the keypanel will be connected. Then, read across to the
“Address” column to find the Address number. Set the keypanel Address switch to this number.
Important! The MKP-4, BKP-4, TKP-4, WKP-4 and MKP-12 keypanels can support ADAM systems up to
two frames in size
