i-SERIES INSTRUCTION MANUAL

Please read and follow these

instructions before operating

an i-station.

IMPORTANT SAFETY INSTRUCTIONS

For your safety, it is important to read and follow these instructions before operating an i-station:

(1) WAR NIN G: To reduce the risk of fire or electric shock, do not expose an i-station to rain or moisture. Do not operate an i-station near water, or place objects containing liquid on it. Do not expose an i-station to splashing or dripping water.

(2) For proper ventilation, make sure ventilation openings are not blocked. Install the i-station according to the directions in the Installation Chapter of this manual.

(3) Do not install an i-station near a heat source such as a radiator, heat register, stove, or other apparatus (including amplifiers) that produces heat. Do not place naked flame sources such as candles on or near an i-station.

(4) Do not defeat the safety purpose of the polarized or grounding-type plug. A polarized plug has two blades, with one blade wider than the other. A grounding-type plug has two blades and a third grounding prong. The wide blade or the third prong is provided for your safety. If the provided plug does not fit into your outlet, consult an electrician for replacement of the obsolete outlet.

(5) Protect the power plug from being walked on or pinched particularly at plugs, convenience receptacles, and the point where they exit from the i-station’s chassis.

(6) Only use attachments/accessories specified by Clear-Com Intercom Systems.

(7) Unplug the i-station during lightning storms or when unused for long periods of time.

(8) Refer all servicing to qualified service personnel. Servincing is required when:

•The i-station has been damaged in any way, such as when a power-supply cord or plug is damaged.

•Liquid has been spilled or objects have fallen into the i-station’s chassis.

•The i-station has been exposed to rain or moisture.

•The i-station does not operate normally.

•The i-station has been dropped.

Please familiarize yourself with the safety symbols in Figure 1. When you see these symbols on an i-station, they warn you of the potential danger of electric shock if the i-station is used improperly. They also refer you to important operating and maintenance instructions in the manual.

i-SERIES INSTRUCTION MANUAL

Clear-Com i-series intercom

stations are designed with

configurable front and back

panels.

OPERATION

DESCRIPTION

The i-series intercom stations for Matrix Plus 3 represent an innovative concept in intercom station design. Each station is constructed from several individual units called modules, which can be added or removed in the field, giving you exceptional flexibility in planning a station’s initial configuration and then easily changing the configuration as future operational needs change.

OPERATIONAL FEATURES

The i-series design emphasizes simplicity. No specialized training is required to operate an i-series station. Intuitive lighting indicates the status of keys for ease of use. Each key may be programmed as either a talk, a listen, or a talk-with-listen.

Features of the i-stations include:

• Configurable front-panel modules. You can choose the number of keys on a station—from 8 to 32—and add or remove keys as needed. Configurable expansion panels are available to give you access to up to 32 more keys, for a total of 64 keys in two rack units (2 RU) controlled by one station.

You have exceptional

flexibility to plan a station’s

initial configuration and then

easily customize the

configuration as future

needs change.

• Full graphic LED-backlit displays for each key on display stations.

• 16-button keypad module for DTMF dialing and station reprogramming.

• Individual crosspoint volume adjust on every station.

• Auto-sensing headset and microphone connectors.

• Access to multiple audio sources and multiple speaker and headset inputs and outputs when an auxiliary options module is installed. The auxiliary options module provides you with two relays and two GPIs (general-purpose inputs) that can be used either locally or system-wide.

• Advanced menu features allow you to assign new destinations and sources to your station directly from your station, to program IFB sources and destinations, to dial telephone interfaces, to transform your station into an assignment panel, to reset local volume levels, and more.

I-SERIES CONSTRUCTION

i-Series stations are sturdily constructed from the highest quality components. Each i-station’s chassis is constructed of cold-rolled steel. Front-panel modules and removable rack ears are cast from aluminum. All external connectors and switches are made of the highest quality components and are structurally reinforced.

i-SERIES INSTRUCTION MANUAL

1-1

Keys feature long-life LED illumination. Displays are full-graphic LCD with long-life LED backlighting. LEDs are made of non-organic materials which ensure years of trouble-free use.

i-Series internal architecture is based on the widely used Motorola M-Core processor. All audio is digitized by CODECs and routed to a DSP to be controlled as desired by the user.

All i-series stations have internal power supplies.

I-SERIES MODULES

i-Series intercom stations are designed in standardized units called modules. Because the stations are designed this way, you can add or remove components, such as keys, in the field without replacing the entire intercom station. Repairing and upgrading stations is easier, faster, and less expensive. The following sections give you an overview of i-series modules.

KEY MODULE

The key module is the basic building block of an i-series intercom station. A station can accommodate from one to four key modules which can be added or removed as needed.

Each key module has eight backlit keys that glow in either green or red to indicate their talk/listen status. Each key has a 5-character alphanumeric display that shows its currently programmed assignment. The alphanumeric name of an assignment is typically called a “label.”

Display stations feature backlit LCD displays with labels that are updated instantly as you program them from the PGM-WIN Configuration Program. Non-display stations have slots for paper labels. You can print and update paper labels from the PGM-WIN Configuration Program. A display and non-display key module are illustrated in Figure 1.

FUNCTION KEY MODULE

The function key module contains the intercom station’s basic and advanced controls. There are two types of function key modules in the i-series. The 16-key

i-SERIES INSTRUCTION MANUAL

module has a numeric keypad while the 4-key module does not, as illustrated in Figure 2.

The 4-key module contains the keys that control basic intercom functions such as switching between gooseneck/headset speakers and microphones, sending call signals, and adjusting listen levels. It has separate volume controls for intercom and program sources. The operation of the this module is discussed later in the chapter.

The 16-key module includes the basic function keys and adds a 12-button numeric keypad for dialing telephone interfaces and for programming advanced features. Advanced features allow you to:

• temporarily deactivate all latched keys on a station

• override the on/off or volume settings at a destination

• assign new sources and destinations to your station from your station

• program IFB sources and destinations

• reset microphone and sidetone volume levels

• receive a variety of information about your station on the station’s LCD displays.

These functions are described in detail later in this chapter.

The auxiliary options module connects your i-station to a variety of audio and control inputs and outputs. It is an optional module that can be installed in the factory or in the field, depending on your needs. Located on the rear-panel of the i-station’s chassis, it provides the following functions:

• General purpose inputs

•Relay outputs

• Speaker-feed output

•Line-level output

• Hot-microphone output

• Balanced-program input

• Auxiliary microphone input

The auxiliary option module’s functions are described in detail later in this chapter.

CONSTRUCTING AN I-STATION FROM MODULES

All i-series intercom stations are constructed of selected combinations of the front- and rear-panel modules. There are a total of eleven front-panel modules and two rear-panel modules in the i-series. Figure 5 on page 1-5 shows you the eleven front-panel modules. Figure 6 on page 1-6 shows you some typical i-stations formed from the basic modules.

POWERING AN I-STATION

NON-DISPLAY KEY MODULE START-UP SEQUENCE

When a station with non-display key modules is connected to power, all keys on each key module will flash red, then green, and will revert to their programmed colors (red for talk or talk-with-listen; green for listen). If there is no communication to the Matrix, the keys will flash red once per second until communication to the Matrix is established.

DISPLAY KEY MODULE START-UP SEQUENCE

When a station with display key modules is connected to power, each of the display modules will show the following message:

Clear-Com

Vx.x.x@2000

“V.x.x.x” represents the firmware version of the panel. All keys will flash red, then green, and will show their programmed colors and labels if there is communication to the Matrix.

If there is no communication to the Matrix, the display will show the message “No connection to Matrix.” The keys will then flash red once per second until communication to the Matrix is established.

FUNCTION KEY MODULE START-UP SEQUENCE

When an intercom station is connected to power, all of the keys on the function key module will flash red, then green, and will revert to their programmed colors if there is communication to the Matrix.

If there is no communication to the Matrix, the keys will be dark until communication is established.

FRONT PANEL CONTROLS AND LIGHTS

A NOTE ABOUT TERMINOLOGY

In this manual, the term “source” refers to a device—intercom station, interface, beltpack, or a variety of other devices—that sends audio to your intercom station. It represents a “listen” path to your station. The term “destination” refers to a device to which you send audio. It represents a “talk” path from your intercom station.

The names of these sources and destinations appear in the display of your intercom station and are called “labels.” A label is a 5-character alphanumeric name that identifies a source, destination, or control function accessed by your intercom station.

i-SERIES INSTRUCTION MANUAL

1-7

ABOUT DISPLAYS

The 5-character name, or “label,” that you assign to a key is displayed next to the key on the key module. The labels on the upper row refer to their corresponding upper-row keys and the labels on the lower row refer to their corresponding lower-row keys.

Keys

Active keys are bright red or

green. Non-active keys are

dim red or green. Keys that

are not assigned are off,

with no illumination.

Alphanumeric Key Names or "Labels"

Display stations have full-graphic LED-backlit displays that you program either from the station itself or from the PGM-WIN Configuration Program. Non-display stations have metal grooves into which paper labels can be inserted. Paper labels can be printed from the PGM-WIN Configuration Program.

ABOUT KEYS

Each key on any key module can be assigned as a talk, a listen, or a talk-with-listen from the PGM-WIN Configuration Program. See the PGM-WIN Configuration Program Manual for more information.

Temporary or Latched Action

When you press a key to talk or listen, the key can be switched on either temporarily or continuously.

When you switch a key on temporarily, it is active for the particular period of time you require. Press and hold the key down for the desired length of time needed to talk or listen, then release the key to return it to its non-active state. You will only be able to talk or listen while you press the key.

1-8

Continuous or “latched” action allows you to lock a key into place, so that you can talk or listen hands-free. Quickly tap a key to “latch” or “lock” it into place to talk or listen. The key will glow brightly to indicate that it is active. The key will remain latched until you tap it again to return it to its non-active state.

Active and Non-Active Keys

When you activate a key—that is, when you press or latch the key to talk or listen— the key becomes bright red or green. When you press or latch an assigned talk key, the key lights up bright red while you talk to the destination.

i-SERIES INSTRUCTION MANUAL

When you press or latch an assigned listen key, the key lights up bright green while you listen to the source.

Otherwise, a key that is not active—that is, a key that is not being used to talk or listen— will be dimmed: dim red for a talk or talk-with-listen key; dim green for a listen key.

Table 1 shows the key colors associated with active or non-active talk, listen, or talk-with-listen keys.

KEY ACTIVE NON-ACTIVE

TALK

LISTEN

TALK-WITH-LISTEN

A talk key glows bright red when you press or latch the key to talk.

A listen key glows bright green when you press or latch the key to listen.

A talk-with-listen key glows bright red when you press or latch the key to talk.

When you activate a listen, the talk-with-listen key will glow bright green.

Table 1: Key Colors for Active and Non-Active Keys

A talk key glows dim red when it is not active.

A listen key glows dim green when it is not active.

If in talk mode, a talk-with-listen key glows dim red when not active.

There is no non-active listen mode. A talk-with-listen key always reverts to non-active talk.

ABOUT LIGHTS

A key can be programmed to light up in a variety of ways to indicate its status. These options are discussed in the following sections. If you decide to use one of these options, it must usually first be set up in the PGM-WIN Configuration Program. A table summarizing all of the light options is located at the end of the section.

i-SERIES INSTRUCTION MANUAL

Call-Waiting Light

A key will flash rapidly (four times per second) when a source calls you. When you press the key to talk, the key becomes bright red to indicate that it is active. When you release the key, it becomes dim red to indicate that it is is not active, if the source is no longer sending audio.

If a key is active when a second source calls you, the key will not flash at the call-waiting rate, but will continue to glow solidly bright red to indicate that it is active. You will know another source is calling because you will hear their audio, the answer-back key will blink, and the source’s label will appear in the display

1-9

above the answer-back key. You can answer the second source by pressing the answer-back key.

This option is set up by default in PGM-WIN, and it can be changed or cancelled if desired. Both the call-waiting light flash length and the amount of time the light flashes before the call is removed from the answer-back stack are programmable in PGM-WIN.

To configure the settings for this feature in PGM-WIN, choose Local Preferences from the Configure menu, then select Answer-Back Auto-Clear Time from the Option Description list. See the PGM-WIN Configuration Program Manual for more information.

In-Use Light

A key will double-flash once per second to indicate that a destination you are trying to call is in use.

The in-use light is a feature that must be set up in the PGM-WIN Configuration Program. It is not the default option. To select the option, choose Global Advanced from the Configure menu, and click the box labeled In-Use Tally. For more information, see the PGM-WIN Configuration Program Manual.

Priority-Conflict Error Light

A priority conflict error occurs if you try to call a destination that is being accessed by another caller with a higher priority.

To indicate the priority conflict, your station’s speaker will beep twice and the destination’s key on your station will flash red rapidly when you press the key to talk. You will not be able to talk to the destination until the higher priority call has ended.

Telephone Off-Hook Light

A key will flash red once per second if a telephone interface is assigned to that key, and the telephone interface is off-hook. The central Matrix will cause each key assigned to the telephone interface on every station in the system to flash at the off-hook rate whenever the telephone interface is active (off-hook) at one or more of the stations.

If you press or latch a key that is flashing at the telephone off-hook rate, the key will glow solidly bright red to indicate that the key is active. When you release the key, it will resume flashing at the telephone off-hook rate.

This telephone off-hook light is set up by default in PGM-WIN, but it can be deactivated if necessary. To access the option settings in PGM-WIN, choose Applications from the Configure menu, and click the box labeled Telephone Off-Hook Tally. For more information, see the PGM-WIN Configuration Program Manual.

1-10

i-SERIES INSTRUCTION MANUAL

Radio-Receiver Active Light

The green light on a key will flash once per second if a radio receiver is assigned to that key, and the radio receiver is active. The central Matrix will cause each key assigned to the radio receiver on every station in the system to flash at the radio-receiver active rate whenever the radio receiver is active at one or more of the stations.

If you press or latch a key that is flashing at the radio- receiver active rate, the key will glow solidly bright green to indicate that the key is active. When you release the key, it will resume flashing at the radio-receiver active rate.

The radio-receiver active light is a feature that must be set up in the PGM-WIN Configuration Program. To select this option, choose Applications from the Configure menu, and click the box labeled Receiver Active Tally. For more information, see the PGM-WIN Configuration Program Manual.

Station-Connected Light

When the station-connected light option is selected in PGM-WIN, any time a destination station is connected to the Matrix frame, its assigned key on your station will flash red once per second. This option is primarily used when a destination station is connected to the Matrix frame via a long-line link (such as an ISDN or T1 link) that might be active only at certain times.

The station-connected light is a feature that must be set up in the PGM-WIN Configuration Program. It is not the default option. To select this option, choose Local Preferences from the Configure menu, and click Station Connected Tally in the Option Description list. For more information, see the PGM-WIN

Configuration Program Manual.

Audio-Presence Light

If you assign a source to your station as a listen-only key, the key will flash green once per second if there is audio present at the source.

The audio-presence light is a feature that must be set up in the PGM-WIN Configuration Program. It is not the default option. To select this option, choose Local Preferences from the Configure menu, and click Enable Audio Presence Tally in the Option Description list. For more information, see the PGM-WIN Configuration Program Manual.

Incompatible Firmware Light

If the firmware on your station is incompatible with the Matrix, all lights on the station will blink bright red once per second, and if displays are present, they will read: “Firmware Version Incompatible.”

ANSWER-BACK FEATURE

With the answer-back feature you can reply to incoming calls from sources not assigned to keys on your intercom station. You can also call out to destinations not assigned to keys on your station.

1-12

If a second unassigned source calls you while you are speaking to the first unassigned source, the second call will be placed in the “answer-back stack,” a group of up to six waiting calls that are answered in sequence.

NOTE: All incoming calls can be answered at the answer-back key—whether from sources with assigned keys on the intercom station or from sources without assigned keys. Typically, however, only calls from sources without assigned keys are answered there.

The following sections describe how to use the answer-back feature.

Answer-Back and Clear Keys

The answer-back key is the leftmost lower key on any intercom station. The clear key is the leftmost upper key on any intercom station. (See Figure 8.) The keys are labeled “ANSWR” and “CLEAR.”

i-SERIES INSTRUCTION MANUAL

Clear Key

You cannot latch an

outgoing call from the

answer-back key. This

function is momentary only.

Clear Key

Answer-Back Key

Figure 8: Answer-Back and Clear Keys

Answering a Call with the Answer-Back Key

When a source that is not assigned to a key on your station calls you:

• The calling source’s label appears in the display above the ANSWR key.

• The ANSWR key flashes bright red to indicate a waiting call.

These conditions will continue until you press the ANSWR key to talk or until the answer-back time-out period lapses and the call is automatically removed from the answer-back stack.

NOTE: The answer-back time-out period is set in the PGM-WIN Configuration Program. It can be set between 10 and 60 seconds. After the time-out period has elapsed, the call will be removed and will no longer be available to answer.

To answer a call from an unassigned source at the answer-back key:

1. Press the ANSWR key to talk to the caller. When you press the ANSWR key, it becomes solid red to indicate that it is active. Note that the ANSWR key cannot be latched; it is a momentary

function.

2. When you complete the call, release the ANSWR key. When you release the key, it becomes dim red to indicate that it is inactive.

3. Press the CLEAR key to remove the caller’s label from the display.

• The display clears automatically when the answer-back time-out period elapses after you release the ANSWR key.

• See Figure 9 for an illustration of answering a call from an unassigned source at the answer-back key.

• The second caller’s audio will come through on your station’s speaker.

• The second call will be placed in the “answer-back stack” (a call list of up to six possible waiting calls). The second caller’s label will appear directly above the current caller’s label. The current caller’s label appears in the display directly above the ANSWR key.

• The light on the ANSWR key will flash to show that a call is waiting and that a call is currently in progress—by flashing at the call-waiting rate to show that a call is waiting; but flashing bright red–dim red instead of the usual bright red–off to show that a call is also currently in progress.

To answer a call waiting in the answer-back stack:

1. Press the ANSWR key to speak to the caller.

The new caller’s label will appear in the position directly above the ANSWR key, while the next waiting call (if there is one) will display in the position directly above it. A total of six calls can wait in the answer-back stack. Only the two most recent caller’s labels will appear in the display above the ANSWR key.

2. When you complete the call, release the ANSWR key.

3. Press the CLEAR key to remove the caller’s label from the display.

• The next unassigned caller’s label appears in the display above the ANSWR key.

Adjusting Program Input Volume

You receive program input at your station through the auxiliary options module, so this module must be present before you can adjust the program input. If you do not have the auxiliary options module installed on your station, the VOL/PROG knob on the function keypad will not operate.

You adjust the program input volume on your station’s speaker and headset with the program volume knob, labeled “VOL/PROG” on the function key module. Turn the knob clockwise to increase the volume, counterclockwise to decrease it.

The six LEDs located to the left of the program volume knob indicate the program volume level. As the volume goes up or down, the number of LEDs that are illuminated changes. Minimum volume is indicated by one illuminated LED; maximum volume is indicated by six illuminated LEDs.

You control the brightness of the six-segment LED with the Display Brightness settings in the PGM-WIN Configuration Program. Refer to the PGM-WIN Configuration Program Manual for more information.

Note: You can also use the program volume knob to adjust listen levels, to scroll through menu items, and to select menu items. These functions are discussed later in this chapter.

Adjusting Listen Levels

When you need to monitor several incoming sources at once, you can vary the volume of the sources by setting “listen levels.”

For example, in a control room you may be listening simultaneously to the lighting department, the sound department, and the tape editing department, but because you need to cue the director when the show is ready to go on the air, listening to the tape editing department takes highest priority. You need to adjust the volumes of the monitored sources so that the tape editing department is louder than the others. To do this, you set listen levels.

There are two ways to adjust listen levels. One method requires using two hands, while the other method requires using only one hand. Both methods are described below.

1-16

i-SERIES INSTRUCTION MANUAL

To adjust the listen level of an incoming source:

Method 1 (Two-handed)

This method works with both the 4-button and 16-button function key modules.

1. Press and hold a listen key.

2. At the same time that you are pressing and holding the listen key in step 1, rotate the VOL/PROG knob either clockwise to increase the volume of the source or counterclockwise to decrease the volume of the source.

You will be able to hear the audio as you adjust it.

3. When you have completed adjusting the volume, release the listen key. The volume will remain at the level to which you have adjusted it.

NOTE: If you try to push an active listen path higher than the maximum possible volume, you will drive the volume of all other active paths downward, thus putting more emphasis on the desired path.

SHORTCUT To quickly enter listen-level adjust mode, simply press three keys in quick succession: #GRN, 7, 5. The words "listen level" will appear in the station's leftmost display. Then proceed from step 5.

Tap any listen key or talk-with-listen key to select it.

Rotate the VOL/PROG knob clockwise to increase the source's volume

or counterclockwise to decrease the source's volume.

Figure 12: Basic Function Keys

GN MIC (GOOSENECK MICROPHONE ON/OFF)

MAIN

i-SERIES INSTRUCTION MANUAL

The gooseneck microphone key, labeled “GN MIC,” turns your station’s gooseneck microphone on or off. Press once to turn the microphone on; press again to turn the microphone off.

The gooseneck microphone is your station’s default microphone unless a headset is plugged in. When a headset is plugged in, an auto-sensing circuit in the station automatically turns the headset microphone on and turns the gooseneck microphone off. The headset microphone always takes precedence over the gooseneck microphone.

If you press a talk key while the gooseneck microphone is plugged in but off, the gooseneck microphone automatically turns on for the duration of the call. The GN MIC key glows dim green whenever the gooseneck microphone is present but off and bright green whenever the microphone is present and on. If a gooseneck microphone is not present, the GN MIC key will not illuminate. Table 4 summarizes the key colors for active and non-active microphone and speaker keys.

1-19

HS MIC (HEADSET MICROPHONE ON/OFF)

The headset microphone key, labeled “HS MIC,” turns your station’s headset microphone on and off. Press once to turn the microphone on; press again to turn the microphone off.

When a headset is plugged in to the station, the headset microphone automatically becomes active and the gooseneck microphone is switched off. To switch to the gooseneck microphone, press the gooseneck microphone key, labeled “GN MIC.” When the headset is unplugged, the gooseneck microphone automatically becomes active.

The HS MIC key glows dim green whenever a headset microphone is present but off, and bright green whenever a headset microphone is present and on. When a headset microphone is not present, the key will not illuminate. Table 4 on page 1-22 summarizes the key colors for active and non-active microphone and speaker keys.

SPKR ON (SPEAKER ON/OFF)

The speaker on/off key, labeled “SPKR ON,” functions only when a headset is plugged into the station. Pressing the speaker on/off key toggles the headset speaker on and off. Press the key once to turn the headset speaker off, and again to turn the headset speaker back on. As the headset speaker turns off, the panel speaker will turn on and vice versa.

The key glows dim green whenever the headset speaker is off, and bright green whenever the headset speaker is on.

NOTE: Unlike the microphones, both speakers can never be turned off at the same time. The panel loudspeaker is always active unless a headset or alternative speaker source has replaced it. That is why this key is non-functional when a headset is not plugged in.

LISTEN (LISTEN-ONLY/CALL SIGNAL/REMOTE TELEPHONE LINE RELEASE)

The LISTEN key has three functions:

• Activates the “monitor mode” of a “talk-with-listen” key

• Sends call signals

• Releases remote telephone lines

Figure 13 summarizes how to access these functions from the LISTEN key. The sections that follow discuss the functions in detail.

1-20

i-SERIES INSTRUCTION MANUAL

MONITOR MODE To activate the "listen" function of a "talk-with-listen" key, press the LISTEN key less than five seconds ("tap" the key)

and then tap the desired "talk-with-listen" key. The LISTEN key illuminates bright green.

2. Tap a dim-green key to activate it. The key glows bright green to indicate its change to an active listen-only key.

3. To talk to the source, press and hold the key. The key glows bright red to indicate that a talk-with-listen call is active. When

you release the key, it reverts back to its active listen-only mode (bright green). The talk-with-listen function cannot be latched; it is only active while you press the key.

To cancel the key’s monitor mode and revert back to the talk-with-listen mode:

1. Tap the LISTEN key on the function-key module.

2. Tap the desired active listen-only key (bright green). The formerly active listen-only key now glows dim red to indicate that it has

reverted back to its non-active talk-with-listen mode. If you press the key to talk, it glows bright red.

NOTE: You must tap the LISTEN key on the function key module for each key you activate in “monitor mode.”

Sending Call Signals

A call signal is an electronic signal that is sent from one station or interface to another to get a station operator’s attention. It can be used for a variety of more technical purposes as well, such as to activate a relay to open a door, set off an alarm, or activate a public address (PA) system.

To send a call signal:

1. Press and hold the LISTEN key for between 1 and 5 seconds. The LISTEN key turns bright red to indicate that you have entered the “call-signal send” mode.

2. Press the key of the destination that you want to send the call signal to. A call signal of three loud beeps is sent to a destination each time that you

press the destination’s key.

3. To send a call signal to a new destination, press the new destination’s key. A call signal is sent to the new destination each time you press that

destination’s key.

4. To exit “call-signal send” mode, tap the LISTEN key and release.

• You can also exit “call-signal send” mode by simply not pressing a display key for five seconds. The mode will automatically time-out.

1-22

i-SERIES INSTRUCTION MANUAL

• When you exit “call-signal send” mode, the LISTEN key changes from bright red to no illumination.

You can send a call signal to any destination with a designated key on your station. If more than one destination is assigned to a key, each destination will receive the call signal. If the destination is a party line, then every station listening on the party line will receive the call signal.

NOTE: The call signal is sent at the page-override volume level, which is programmable in the PGM-WIN Configuration Program. For more information, see the PGM-WIN Configuration Program Manual .

Releasing Remote Telephone Lines

To release a telephone interface that has been left off-hook:

1. Enable “remote telephone release” for that station in the PGM-WIN Configuration Program.

Often this feature will already be set up in the Configuration Program. For more information, refer to the PGM-WIN Configuration Program Manual.

2. Press and hold the LISTEN key for more than 5 seconds. The LISTEN key turns bright green and flashes on and off.

3. While still holding the LISTEN key, press the desired telephone interface key on any key module.

The telephone interface will hang up. All audio paths to and from the telephone interface will be deactivated.

4. Release the LISTEN key to exit.

With your i-station or i-station expansion panel, you can assign an external audio source, often called a “program” source, to a destination. Typically this function is used to route “on-the-air” audio to the “talent” or announcer in a television studio application, but it can have many other uses as well.

You must set up this function in the PGM-WIN Configuration Program before you can use the i-station or the i-station expansion panel to assign external audio sources to destinations.

Note that this feature is only active when the Matrix is connected and online.

To choose assignment panel function in the PGM-WIN Configuration Program:

1. From the Configure menu, select Local Preferences. The Configure dialog box opens, with the Local Preferences tab selected.

2. In the leftmost upper area of the dialog box, select the Stations option. A list of stations in the intercom system appears.

3. Click the desired station. A list of possible options for the stations appears in the Option Description

area.

4. In the Option Description area, click either:

• Enable AP Function

When you select this option both the intercom station and its connected expansion panel will become assignment panels.

• AP Function on Expansion Panel Only

When you select this option only the expansion panel will become an assignment panel. Its connected intercom station will function as usual.

5. Click OK. Your i-series intercom station and/or expansion panel now functions as an

assignment panel. The following section describes the procedure for assigning a destination to a source from the assignment panel.

To assign a destination to a source from the i-station or expansion panel:

1. Press “4” on the i-station’s numeric keypad. All sources blink green and all destinations blink red. The words “IFB Enter”

appear in the station’s leftmost display.

2. Press a destination’s key on your station to select it. The selected destination’s key glows solid red.

3. Press a source’s key on your station to select it.

• The selected source’s key glows solid green.

• To select more than one source you must check the “Assign multiple sources to IFB from AP Panel” option on the System Preferences dialog box in the PGM-WIN Configuration Program. For more information, see the PGM-WIN Configuration Program Instruction Manual.

4. Press Enter or Return. The selected source or sources of program audio are assigned to the selected

destination. Although you can select more than one source of program audio, you can select only one destination.

PICK LIST SCROLL (#5 KEY)

The “pick list scroll” feature allows you to assign any intercom station or interface in the system to a key on your station directly from your station. You can assign the station or interface to your station as a talk key, a listen key, or a talk-with-listen key.

To do this, you first access a list of all stations and interfaces in the system on the front-panel display of your i-station. You then scroll through the list and select the station or interface that you want to assign to your station. In other words, you literally “pick” from a “list” that you “scroll” through. This feature is only available when the Matrix is connected and online.

Two procedures are described below. The first describes how to assign a remote destination to your station as a “talk” or “talk-with-listen” key. The second describes how to asssign a remote source to your station as a “listen” key.

A list of current destinations in the system appears

in the leftmost display on the station. Scroll through the list. See the procedure for more information.

Assign the selected remote station or interface to a key on your

station by tapping the desired key for less than 1/2 second to assign it as a "talk" or for more than 1/2 second to assign it as a "talk-with-listen."

For instructions see the earlier section “Setting Up GPIs (General Purpose Inputs) in PGM-WIN.”

2. Connect a logic device (such as a foot switch, a panel-mounted switch, or the logic output of another device) to the i-station’s GPI connector.

3. Switch on the logic device to shut off the audio going from the station to the frame.

Note that the “hot-microphone” output has not been shut off.

Microphone Off (Momentary)

The “Microphone Off” function allows you to set up an external logic device, such as a panel-mounted switch, a foot switch, or the logic output of some other device, to momentarily shut off the station’s microphone.

While you press and hold the switch on the remote device, the microphone is shut off, but when you release the switch, the microphone resumes normal operation.

To use a logic device to turn the station’s microphone off momentarily:

1. Select the “Microphone Off (Momentary)” option in the PGM-WIN Configuration Program.

For instructions see the earlier section “Setting Up GPIs (General Purpose Inputs) in PGM-WIN.”

2. Connect a logic device (such as a foot switch, a panel-mounted switch, or the logic output of another device) to the i-station’s GPI connector.

3. Switch on the logic device to shut the station’s microphone off momentarily. While you press and hold the switch on the logic device, the microphone is

shut off, but when you release the switch, the microphone resumes normal operation. This function cannot be latched.

Answerback Talk/Clear

The “Answerback Talk/Clear” function allows you to set up an external logic device, such as a panel-mounted switch, a foot switch, or the logic output of some other device, to function as the station’s answer-back key.

1-42

i-SERIES INSTRUCTION MANUAL

To use a logic device to activate the station’s answerback key:

1. Select the “Answerback Talk/Clear” option in the PGM-WIN Configuration Program.

For instructions see the earlier section “Setting Up GPIs (General Purpose Inputs) in PGM-WIN.”

2. Connect a logic device (such as a foot switch, a panel-mounted switch, or the logic output of another device) to the i-station’s GPI connector.

3. Switch on the logic device to activate the station’s answer-back key. Holding down the switch activates a talk path to the current destination in the answer-back stack.

Note that the logic switch, like the answer back key itself, cannot be latched. It functions momentarily only.

4. To clear the current call, and go to the next call in the answer-back stack, quickly press and release the switch.

Speaker Off

The “Speaker Off” function allows you to set up an external logic device, such as a panel-mounted switch, a foot switch, or the logic output of some other device, to shut off the station’s loudspeaker.

To use a logic device to shut off the station’s loudspeaker:

1. Select the “Speaker Off” option in the PGM-WIN Configuration Program. For instructions see the earlier section “Setting Up GPIs (General Purpose Inputs) in PGM-WIN.”

2. Connect a logic device (such as a foot switch, a panel-mounted switch, or the logic output of another device) to the i-station’s GPI connector.

3. Switch on the logic device to shut off the station’s loudspeaker.

You can activate all latched

keys at a station with an

external logic device, such

as a headset with a

push-to-talk switch.

PTT: Activate All Talk Keys

The PTT: Activate All Talk Keys function allows you to set up an external logic device, such as a panel-mounted switch, a foot switch, or the logic output of some other device, to activate all latched keys at your station. When the logic device is not activated, you will not be able to talk from any latched key at your station.

For example, some headsets are equipped with a push-to-talk switch on their headset cords. The push-to-talk switch can be wired to operate as logic device. When an intercom operator wants to talk to any destination with a latched key on his station, he will only be able to do so if he first pushes the push-to-talk switch on the headset cord.

To use a logic device to activate all latched talk keys:

1. Select the “PTT: Activate All Talk Keys” option in the PGM-WIN Configuration Program.

For instructions see the earlier section “Setting Up GPIs (General Purpose Inputs) in PGM-WIN.”

2. Attach a logic device (such as a foot switch, panel-mounted switch, a push-to-talk headset, and so on) to the i-station’s GPI connector.

i-SERIES INSTRUCTION MANUAL

1-43

You can install a logic device

to activate a key assigned to

a 2-way radio.

3. Switch on the logic device to activate all latched keys at your station. The logic device will activate keys latched both before and after you enabled

this function in the PGM-WIN Configuration Program

Note that the latched keys at your station may appear to be active, since their talk lights will illuminate, but they actually only activate when you switch on the connected logic device. Any controls (relays, etc.) assigned to the keys along with the audio functions are now also only activated when signaled by the remote device.

You can, however, activate a talk path on any key by pressing and holding the key in momentary mode while you talk. The PTT: Activate All Talk Keys function only affects latched keys.

PTT: Activate 2-Way Radio Talk Keys

The PTT: Activate 2-Way Radio Talk Keys function allows you to set up an external logic device, such as a panel-mounted switch, a foot switch, or the logic output of some other device, to activate all latched keys at your station that are assigned to a 2-Way Radio Interface. The PTT: Activate 2-Way Radio Talk Keys function operates similarly to the PTT: Activate All Talk Keys function, except that it only affects latched keys assigned to a 2-Way Radio Interface. All other latched keys at your station operate normally and are not activated by the logic device.

When the logic device is not activated, you will not be able to talk from any latched key assigned to a 2-way radio at your station.

For example, some headsets are equipped with a push-to-talk switch on their headset cords. In this case, when the intercom operator wants to talk to a 2-way radio from a latched key, he will only be able to do so if he first pushes the push-to-talk switch on the headset cord.

This function is valuable in applications that use 2-way radios because typically these systems transmit on only one frequency, and if more than one person transmits on the same frequency at any one time, the radio waves are interfered with so that no radio operator in the system can hear.

Using the PTT: Activate 2-Way Radio Talk Keys function allows an operator to determine precisely when he transmits audio on a 2-way radio interface.

To use a logic device to activate a key assigned to a 2-way radio:

1. Select the “PTT: Activate 2-Way Radio Talk Keys” option in the PGM-WIN Configuration Program.

For instructions see the earlier section “Setting Up GPIs (General Purpose Inputs) in PGM-WIN.”

2. Connect a logic device (such as a foot switch, panel-mounted switch, a push-to-talk headset, and so on) to the i-station’s GPI connector.

3. Switch on the logic device to activate all latched keys assigned to 2-way radios at your station.

The logic device will activate keys latched both before and after you enabled this function in the PGM-WIN Configuration Program

1-44

i-SERIES INSTRUCTION MANUAL

Note that the latched keys assigned to two-way radio keys at your station may appear to be active, since their talk lights will illuminate, but they are only active

when you switch on the connected logic device. Any controls (relays, etc.) assigned to the 2-way radio keys along with the audio functions now also are only active when signalled by the remote device.

You can, however, activate a talk path from any key assigned to a 2-way radio by pressing and holding the key in momentary mode while you talk. The PTT: Activate 2-Way Radio Keys function only affects latched keys.

Activate Talk Switch #1

The “Activate Talk Switch #1” function allows you to set up an external logic device, such as a panel-mounted switch, a foot switch, or the logic output of some other device, to activate the station’s upper leftmost talk key.

To use a logic device to activate the station’s leftmost talk key:

1. Select the “Activate Talk Switch #1” option in the PGM-WIN Configuration Program.

For instructions see the earlier section “Setting Up GPIs (General Purpose Inputs) in PGM-WIN.”

2. Connect a logic device (such as a foot switch, a panel-mounted switch, or the logic output of another device) to the i-station’s GPI connector.

3. Switch on the logic device to activate the station’s upper leftmost talk key. This feature is momentary only, so that you must press and hold the logic

device’s switch to activate the station’s talk key. When you release the switch, the station’s talk key is no longer activated. The station’s talk key cannot be latched with the Activate Talk Switch #1 option.

Activate Talk Switch #2

The “Activate Talk Switch #2” function allows you to set up an external logic device, such as a panel-mounted switch, a foot switch, or the logic output of some other device, to activate the station’s second upper leftmost talk key (the key directly to the right of the leftmost upper key).

To use a logic device to activate the station’s second upper leftmost talk key:

1. Select the “Activate Talk Switch #1” option in the PGM-WIN Configuration Program.

For instructions see the earlier section “Setting Up GPIs (General Purpose Inputs) in PGM-WIN.”

2. Connect a logic device (such as a foot switch, a panel-mounted switch, or the logic output of another device) to the i-station’s GPI connector.

3. Switch on the logic device to activate the station’s second upper leftmost talk key.

This feature is momentary only, so that you must press and hold the logic device’s switch to activate the station’s talk key. When you release the switch, the station’s talk key is no longer activated. The station’s talk key cannot be latched with the Activate Talk Switch #2 option.

i-SERIES INSTRUCTION MANUAL

1-45

The relay outputs connector

connects an i-station to two

single-pole double-throw

(SPDT) relays.

Contact ratings for the

relays are 30 VDC at 1 A.

J5B

RELAY OUTPUTS CONNECTOR

The DB-15F connector labeled “J5B” connects your i-station to two single-pole double-throw (SPDT) relays with contact ratings of 30 VDC (volts direct current) at 1 A (ampere).

A relay is a switch that you control remotely. You program the relay in the PGM-WIN Configuration Program to close a contact whenever an intercom station’s key is pressed. When the contact is closed it completes an electronic circuit’s signal path so that a remote device, such as a light, is powered.

You can program a relay to mute a speaker, to turn on an applause light, to turn on a door lock, or for a variety of other functions. For example, to get the attention of a station operator working in a high-noise environment such as a control booth, you can program a relay to switch on a light at his station each time he receives an incoming call, thus insuring that he will not miss the incoming call.

The i-station has two relays: the mute relay and the programmable relay.

Mute Relay

The mute relay activates any time you press any talk key on your intercom station.

This relay is typically wired to decrease or shut off the volume on an room’s externally mounted loudspeaker whenever someone in the room presses an intercom station’s key to receive incoming audio, thus insuring that the station operator can hear the audio.

Both normally open and normally closed contacts are provided. They are rated at 30 VDC (volts direct current) at 1 A (ampere). The mute relay is not designed for switching mains AC line voltage. To switch an external device running on mains AC line voltage, use an external relay (or other switching mechanism) activated by the relay.

Programmable Relay

The programmable relay is controlled by the PGM-WIN Configuration Program. When you attach the programmable relay to any source or destination’s label in the intercom system through the PGM-WIN Configuration Program, whenever that label’s key is pressed on any station in the system, the relay activates as well.

Typically, a relay is used to activate an external device such as an applause light in a studio, a cue light, or a security door lock. For example, you can program a relay so that whenever anyone in the intercom system presses a key to talk to a specific station, the relay in that station will activate and turn on a visual indicator (such as a light) to get the station operator’s attention.

1-46

NOTE: You can activate a relay that is independent of any talk-or-listen function by creating a “control” label in the PGM-WIN Configuration Program. When you

i-SERIES INSTRUCTION MANUAL

activate the control label, only the relay activates. No audio signal activates in conjuction with the relay.

External Speaker Input Connector

The 1/8-inch tip/sleeve mini-connector labeled “J6” connects to and powers an external speaker. Its impedence rating is 4–8 Ohms and its power rating is 1/2 watt at 4 Ohms.

Note that when you plug an external speaker into this connector, the front-panel internal speaker is still active. You can deactivate one or both speakers through the PGM-WIN Configuration Program.

The front-panel’s main-volume knob controls the volume for both the rear-panel and front-panel speakers. The volume of both speakers is the same.

Line-Level Output Connector

The 1/8-inch tip/ring/sleeve mini-connector labeled “J7” is a line-level, transformer-balanced output of all of the audio that comes to the station from the central Matrix. All of the audio that you would hear at a station’s speaker, from all sources, is sent through this connector. The output’s volume is at line level, bypassing the station’s audio controls.

This output is typically connected to an externally powered speaker, amplifier, or ceiling speaker system.

The line-level output connector’s output impedence is 600 Ohms and its level is nominally 0 dBv. Frequency response is 50 Hz–15 kHz (± 2 dB).

Hot-Microphone Output Connector

The A3M standard XLR connector labeled “J8” provides a line-level output of the selected microphone’s audio (headset or panel) that is always “on” (or “hot”). Only the station’s microphone on/off key can override this output.

This connector’s output impedence is 600 Ohms. Its level is nominally 0 dBv. Frequency response is 50 Hz–15 kHz (± 2 dB).

A typical application is to permanently wire the station’s microphone audio output to all cameras so that the camera operators can hear the director at all times, regardless of what other tasks they are performing. This audio output can also be connected to many types of external speakers, such as external wall speakers. The purpose of this output is to provide an audio output that is always “on” and cannot be interruped by other audio sources.

NOTE: The PGM-WIN Configuration Program’s “listen” or “eavesdropping” function will accomplish the same results as the hot-microphone output. See the PGM-WIN Configuration Program Instruction Manual for more information.

Balanced Program Input Connector

i-SERIES INSTRUCTION MANUAL

The A3F standard XLR connector labeled “J9” connects an external source of audio to your station so that you can hear it in addition to the intercom audio at

1-47

your station. The external source of audio, or “program” audio, can be heard on your station’s speaker and headset, but it cannot be heard by other stations in the Matrix system.

This line-level, transformer-balanced input can be assigned in the PGM-WIN Configuration Program to either the loudspeaker, the headset, or both. Its volume is controlled by the front-panel program-volume control.

The balanced program input connector’s impedence is 8K Ohms bridging. Its frequency response is 50 Hz–15 kHz (± 2 dB).

J10

External Dynamic Microphone Input Connector

The A3F standard XLR connector labeled “J10” is a balanced input for an external dynamic microphone. It is not transformer isolated. Its input level is -40 dBv with a gain adjustment range of ± 5 dB. Impedence is 200 Ohms.

NOTE: Dynamic microphones generate their own power while electret microphones do not. The J10 connector cannot be modified for an electret microphone.

OPERATING AN I-STATION EXPANSION PANEL

An i-series expansion panel connects to an i-series intercom station and gives you access to 32 additional keys. Figure 26 illustrates an i-series expansion panel. Both the basic and advanced keys on an expansion panel operate the same as their corresponding keys on an i-station.

The expansion panel is available with either five-character LCD displays or with areas for paper labels. It connects to an i-station through an RJ-45 connector on the rear panel.

i-SERIES INSTRUCTION MANUAL

INSTALLATION

INTRODUCTION

This chapter describes how to install an i-series intercom station. For programming information, see the PGM-WIN Configuration Program Manual.

EQUIPMENT PLACEMENT

All i-series intercom stations require one rack unit of space (1 RU) in a standard 19-inch (48.26 cm) rack.

Put all intercom stations at a comfortable operational height. Leave at least 2 inches (5 cm) of clearance at the rear of the station’s chassis to allow for cable connectors and access to the rear-panel controls. For proper ventilation, make sure ventilation openings are not blocked.

WAR N I N G: To reduce the risk of fire or electric shock, do not expose the unit to rain or moisture.

MAINS AC POWER

Each i-station has an internal power supply, with a removable AC power cord. The power supply is “universal,” operating over a voltage range of 90 to 245 VAC and 50 to 60 Hz. The maximum dissipation is 40 W.

ADJUSTMENTS

No initial adjustments are required to set up the stations other than the standard input level adjustment made through PGM-WIN.

CONFIGURATION

Assign each station’s name and other parameters by using the Matrix Plus 3 System Configuration Program. For instructions, see the PGM-WIN Configuration Program Manual.

WIRING

i-Series intercom stations use a twisted 4-pair transmission scheme to connect them to the matrix frame using the industry standard RJ-45 connector. Refer to the Overview section of the Matrix Plus 3 Installation Manual for RJ-45 connector installation and use, and the type of cable needed for connection between stations and frames.

i-SERIES INSTRUCTION MANUAL

Each pair of the twisted 4-pair wire has the following function:

2-1

• Pair 1 transmits analog audio from the matrix port to the station.

• Pair 2 transmits digital data from the station back to the matrix card port.

• Pair 3 transmits audio from the station to the matrix card port.

• Pair 4 transmits digital data from the matrix port back to the station.

MAINTENANCE

INTRODUCTION

This chapter provides maintenance information: troubleshooting tips, block diagrams, component layout drawings, bills of materials, and schematics.

CAUTION: These servicing instructions are for use by qualified personnel only. To reduce the risk of electrical shock, do not perform any servicing other than that contained in the operating instructions unless you are qualified to do so.

GENERAL TROUBLESHOOTING

Every i-station’s microprocessor has a reset button located, as shown in Figure 1, in an unmarked hole located next to the program volume knob (labeled “VOL/PROG”). If a station acts erratically, try resetting it. Often this will clear the problem.

To reset a station, insert a small screwdriver or a piece of wire (such as a bent paper clip) into the hole and push the reset button. Another way to reset the station is to disconnect and re-connect the AC power cord.

GLOSSARY

Answer Back: The answer-back key on an intercom station allows you to respond to calls from stations or interfaces not currently assigned to a key on your station. If more than one source sends audio to you, the waiting calls are stored in the “answer-back” stack in the order they are received until you respond to them or clear them.

Call Signals: A call signal is an electronic signal sent from one station or interface to another. A call signal can be audible and/or visual. It is used to get the attention of a station operator; to control a device, such as a relay or radio transmitter; or to activate the call lights on an external Clear-Com party-line system.

Channel: A two-way talk path.

Destination: A device—intercom station, beltpack, interface, or a variety of

other devices—that you send audio to. A “talk” path is typically established from your intercom station to a destination station or interface.

Download: In traditional computer terminology, to download data means to transfer data from a large computer’s memory to the memory of another device, usually a smaller computer. In this manual, to download data specifically means to transfer data from the Matrix frame to a station, or from the PGM-WIN configuration software to the matrix frame.

ISO: The ISO function, short for “station ISOlation,” allows you to call a destination and interrupt all of that destination’s other audio paths and establish a private conversation. When you complete your call, the destination’s audio is restored to whatever was active before the interruption.

Label: A label is a five-character alphanumeric name that identifies a source, destination, or control function accessed by your intercom station. Labels appear in the displays of the intercom station. Labels can identify stations, ports interfaced to other external equipment, fixed groups, party lines, and special control functions.

Labels can contain as many as five characters, using numbers, capital letters, and all punctuation marks except the question mark. Blank spaces are not allowed as the “leading” (first) character; however, the underscore character (“_”) will appear as a space when viewed on the display screen on an i-station. Blank label names are not allowed. The PGM-WIN configuration program will replace any blank label name with its default.

All labels in the system have a factory default, and any label can be returned to the factory default by typing a “leading” space in the first position and pressing the ENTER key.

For more information on labels, including assigning them in the PGM-WIN configuration program, see the PGM-WIN Configuration Program Manual.

Metric Conversions: The following table gives common metric conversions.

U.S. to Metric Measurement Metric to U.S. Measurement

1 inch = 2.54 centimeters 1 centimeter = 0.39 inch

1 foot = 0.30 meter 1 meter = 3.3 feet

1 mile = 1.6 kilometers 1 kilometer = 0.62 miles

Sidetone: The sound of your own voice heard in your own earphone as you speak.

Source: In this manual, the term “source” refers to a device—intercom station, interface, beltpack, or a variety of other devices—sends audio into the matrix. A “listen path” is established from a station or interface.

Upload: In traditional computer terminology, to upload data means to transfer data from one computer to another. In this manual, to upload data specifically means to transfer data from an station to the Matrix frame, or from the Matrix frame to the PGM-WIN Configuration Software.

Rack Unit or RU: Standardized unit of mounting space on a rack panel. Each rack unit is 1.75 inches of vertical mounting space. Therefore 1 RU is 1.75 inches of vertical mounting space, 2 RU is 3.5 inches, 3 RU is 5.25 inches, and so on.

PGM-WIN Configuration Program: Windows-based software program that controls the central matrix circuit cards and most features of connected remote stations.
