Introduction

General Description

The RTS ™ KP-812 keypanel fits in a standard 19” rack and is one rack space high. It has 12 keys (one listen button and one talk button make up a key): 10 keys are for intercom talk and listen, two keys are for call waiting response.
In addition, there are two encoders. One encoder is used for headset, microphone, auxilliary input, and matrix in volume adjustment. The other encoder knob is used for menu selection. The KP-812 keypanel has a stan­dard numerical keypad with four extra keys: Mic Mute, User Assignable, Page Up, and Page Down.
The KP-812 keypanels add significant new features such as digital signal processing.
KP-812 keypanels also offer a custom design LCD display with support for 16x16 Kanji, Katakana, Hiragana, and English characters.
The KP-812 keypanels are made of pressed aluminum / metal and feature state of the art audio processors and drivers. There are three different models of keypanel to choose between - Desktop, Desktop with Handset and Rackmount.

The relay 2 and 4 contacts are electrically separate, but operate in unison. The +3.3 VDC pins are connected internally through 1K resistors to +3.3 VDC and can source 3 mA. This voltage can be used with the relay contacts to create an active high output for some devices that require a +3.3 VDC signal to activate. For example, connecting pin 7 to pin 3 of the Relay 1 & 2 connec tor will result in +3.3 VDC on pin 2 when the relay is activated.

Installation

Note: To see where the DIP Switch is on the circuit board, see Figure 4, page 20.
DIP Switch Settings
Switch 1: Latch Enable/Disable
Default Setting: Open (Enable) 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 often used by a director or producer to give instructions to a listener, such as a news anchor during a television broadcast) could accidently be left on, causing confusion for the IFB listener. To prevent such acci­dents, the latching feature can be turned off.
2
NOTE: DIP Switch 1 disables latching for the entire keypanel. If you just need to disable latching for
selected keys, leave DIP Switch 1 in the “open” position. Then, disable latching for the desired keys using the “D” check boxes in the Keypanels/Ports setup screen in AZedit.
Switch 2: Enable/ Disable the adjustment of listen volumes.
Default Setting: Open (Enable) Description: Enables or disables the Key Gain item in the Key Assign menu.
Switch 3: Unused
Default Setting: Open (Enable)
KP-812 Keypanels User Manual
19
Switch 4: Call Flash Time-out
Default Setting: Closed (Infinite Tally) 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. If this DIP switch is closed the flashing light goes off as the callers talk key is closed. Otherwise, flash time can be set for 15 second time-out, or until the caller’s talk key is released. Call Flash Time-out can be set to 5 sec, 10 sec, and 15 sec.
Switch 5: Footswitch Enable/Disable
Default: Open (Disabled) Description: The optional Connector Module has a footswitch (GRP CALL) input. If the footswitch is
enabled (DIP switch 5 set to the “Closed” position), then keys that are latched on will not activate until the footswitch is closed. Latched keys are indicated by winking amber talk LEDs (on time less than off time), and when the footswitch is activated, the LEDs provide normal talk-on indication.
NOTE:
1. If the talk key is held down in the Footswitch mode, the channel will be activated until the user releases the key. The use of this function does not require the footswitch to be used.
2. If DIP switch 1 is set to the “Closed” position, nothing will latch.
3. Individual keys can be set to non-latching via AZedit. If this is done, the footswitch has no effect on the keys that have been set to non-latching.
Switch 6: Reserved
Switch 7: Reserved. Must be left in the Open position.
Switch 8: Reserved, Must be left in the Open position.

LED Indications for Intercom Keys
Note: For the Japanese model KP-812 keypanel, the talk ON LED will appear red and the Listen ON
LED will appear green.
Talk LED Indications
Each button is back lit with a Bi-colorLED as an indicator. The talk LED is the button below the display panel. The talk LED indications are as follows:
Continuous Red
Talk is on and the keypanel operator can be heard at the destination.
Continuous Green Talk LED & Flashing Display Alpha (“in-use”)
The key is off, but someone is talking to the destination. This indication is provided for any local PL, IFB, ISO, or TIF key. It does not apply to remote IFB or ISO keys. This indication is provided so keypanel operators know when critical director communications are occurring. If you activate the key, either of two things will happen:
• If you activate the key and the talk LED turns continuous red, this indicates you and the other
keypanel operator are both talk to the destination.
• IFB keys only: If the talk LED flashes green when an IFB key is activated, this indicates the
other keypanel has a higher IFB priority and you cannot talk at this time.
Note: The green “in-use” indication for TIF keys can be disabled in AZedit. In the AZedit Options
menu, select Intercom Configuration, then click on the Options tab. Place a check mark next to “Don’t generate tallies for TIF and trunk use”. Be sure to send the change to the intercom system.
Flashing Green Talk LED
You cannot talk at this time. This indication occurs when you activate a local IFB key that is already in use by a keypanel with a higher IFB priority. It also occurs when you activate any key assigned to a remote destination, but there are currently no trunks available.
KP-812 Keypanels User Manual

Flashing Red Talk LED
There is an incoming call from the destination assigned to the key. Activate the key to talk back.
Note: The duration of incoming call flash is controlled by DIP switch 4 on the KP-812 keypanels. See
Option Switch Settings
, for further information.
Amber Talk LED (on time less than off time)
This indicates that a key is ready to talk (key is on), but requires external footswitch activation to talk or the key has been selected but the handset is still on the receiver.
Listen LED Indication
Each button is back lit with a bi-color LED as an indicator. The listen LED is the button above the display panel.

Intercom Key Operation

Basic Intercom Key Operation

The upper button of an intercom key is on continuously (if assigned). The lower button activates the talk (if assigned). If there is no talk assignment for an intercom key, the talk button will not activate. If there is no listen assignment, the listen button will not activate.
For momentary activation of a key, press and hold the key. Then, release it when finished.
For latching operation (if enabled), tap the button; it will turn on and remain on. Tap the button again to turn it off when finished.
Note: Latching may be turned off for the entire keypanel by setting DIP switch 1 on the keypanel to the “closed” position. Latching may be disabled for individual keys on a keypanel using AZedit or the latching menu (Menu>KeyOption>Latching). Click the KP button in the AZedit toolbar to open the Keypanels / Ports setup screen. Select the intercom port where the keypanel is connected. Place a check mark in the check box marked “D” for any keys where you want to disable latching. Be sure to send your changes to the intercom system.

Operation of Intercom Keys with Auto Functions

Note: Assignment of keys with auto functions is described in the programming sections that follow.
Descriptions of the auto functions are also contained in the Glossary.
Operation of keys with auto functions is as follows:
Talk + auto follow
Talk and listen can be activated separately. The listen assignment listens to whatever is assigned to the talk key.
Talk + auto listen
Both talk and listen will activate when talk is activated.
Talk + auto mute
Listen will turn off when talk is activated.
Talk + auto reciprocal
Listen will always be on, and talk may be turned on or off.
Talk + auto table
If an IFB talk key has an auto-table listen assignment, talk and listen can be independently activated. The listen key listens to whatever is defined as the IFB Listen Source for the IFB that is assigned to the talk key. For an assignment other than IFB, auto-table acts like auto-follow.
Note: A full explanation of the auto-table feature is beyond the scope of this manual. For further information, search for IFB in AZedit help, then read the topics
Setup Procedures
.
IFB Auto-Table Description
and
IFB
All Call Key
Activating the key will also activate all keys to the left of it (up to, but not including another all call key).
Talk + DIM
If a point-to-point key has the DIM function as a level 2 talk assignment, activating the key will cause the crosspoint levels to diminish for any other intercom ports that are currently listening to the same destination and that are in the same DIM table.
Note: A full explanation of DIM tables is beyond the scope of this manual. For further information, search for “dim table” in AZedit help.

Operation of Intercom Keys with Options

Group Option Keys
Activating the master key in a key group will activate all keys in that group according to each key’s individual key assignment. Activating a slave key will not affect any other keys in the group.
Solo Key
Activating a key that has the solo option will cause all other keys to turn off until the solo key is again turned off.
Exclusive Key
Activating a key that has the exclusive option will cause all other keys to turn off and stay off after the exclusive key is turned off.

Operation of Intercom Talk Keys with the Speaker DIM Setting

Activating any talk key will cause the speaker or headphone volume at this keypanel to diminish by the amount specified in the Dim menu item on the Service menu.
Note: Do not confuse this with the Talk+DIM auto function previously described. Talk+DIM affects the speaker or headphones on the other keypanels when a particular talk key is activated on this keypanel. Speaker DIM affects the speaker or headphone level on this keypanel when any talk key on this keypanel is activated.

Operation of Intercom Keys assigned to TIF Ports

If an intercom key is assigned to talk to an intercom port that is designated as a TIF port in AZedit, tapping the talk button will activate the KP-812’s dialing menu. See
Telephone Operation
.
Note: You designate an intercom port as a TIF port by checking the Port is TIF check box in AZedit. In AZedit, click the KP button on the toolbar to access Keypanels / Ports setup. Select the intercom port where the TIF is connected, then click Edit. Select the Advanced tab. Select the Port is TIF check box. Remember to send the changes to the intercom system.

Muting the Microphone

Tap the Mic Mute key to turn the microphone muting ON or OFF. The Mic Mute LED indicator acti­vates with a blinking green light.
Note: While muting is on, you cannot be heard on the intercom, by anyone on the telephone, or by any device connected to the mic preamp output of the optional connector module.

Call Waiting Operation

Occasionally, a keypanel may call, and there will not be a key assigned to talk back to that caller. In this case, the caller’s name appears in the back.
To clear a name from a Call Waiting Window, tap the listen key above the assignment.
If two call waiting windows are configured on the keypanel, the first call will display in the left window. If a second call comes into the keypanel, it will display in the right call waiting window. Once the first call is complete the call in the right call waiting window moves to the left call waiting window. However, if the first call waiting window key is latched on and a call is waiting in the second call waiting window and a third call comes in, then the second call is dropped and the third call displays in the right call waiting window.
Call Waiting Window
. Press the appropriate key to talk
30
Note: By default, only the names of callers who are not currently assigned to intercom keys will appear in the Call Waiting Window. This is a configuration option in the Master Controller.
