2 Introduction
This guide describes how to install, use and maintain I-Series™ user panels from ClearCom®
I-Series user panels are fully compatible with both the Eclipse and Eclipse HX digital
matrix systems. Each panel is constructed from several individual units called modules,
which can be added or removed in the field. This enables you plan the panel’s initial
configuration and easily update the configuration as future operational needs change.
The standard configurations include 8, 16 or 32 key panels. Up to five E-1410E expansion
panels can be connected to a single I-Series user panel.

2.2.1 Labels
The names of the sources and destinations appear in the display of your user panel and
are called labels. A label is a 5-character alphanumeric name that identifies a source,
destination, or control function accessed by your user panel.
The label is displayed next to the key on the key module. The labels on the upper row refer
to the corresponding upper-row keys and the labels on the lower row refer to the
corresponding lower-row keys.
Figure 2-1: Labels on a key module
Note: Display modules have full-graphic LED-backlit displays that you program using the Eclipse
/ Eclipse HX configuration software (ECS / EHX). Non-display modules have metal
grooves into which paper labels can be inserted. Paper labels can be printed from ECS /
EHX.

I-Series Panels User Guide
3.2 Chassis assembly
The chassis of the I-Series user panel is constructed of cold-rolled steel. The front-panel
modules and removable rack ears are cast from aluminum. All external connectors and
switches are structurally reinforced.
The keys feature long-life LED illumination, and the displays are full-graphic LCD with
long-life LED backlighting.
The internal architecture of I-Series panels is based on the Motorola M-Core processor. All
audio is digitized by CODECs and routed to a DSP that can be controlled as desired by
the user.
All I-Series user panels have internal power supplies.
3.3 Modules
I-Series user panels are designed in standardized units called modules.
Modules make it easier to add or remove components (such as keys) in the field, without
replacing the entire user panel. This makes upgrading (or repairing) panels easier, faster,
and less expensive.
Note:
For more information about using modules, see [put link here].
3.3.1 Key module
The key module is the basic building block of the I-Series user panel. A panel can host up
to four key modules.
The eight backlit keys in each key module are:
• Lit red to indicate talk status.
• Lit green to indicate listen status.
Each key has a 5-character alphanumeric display that shows its currently programmed
assignment. The alphanumeric name of an assignment is called a label.
ECS / EHX, the configuration software for Eclipse / Eclipse HX, is used to program the
labels for I-Series panels featuring backlit LCS displays.
User panels without display screens have slots for paper labels.

4 Using I-Series panels
This chapter describes how to use the I-Series panels, including:
• Powering up I-Series panels.
• Front panel lights and controls.
• Key module lights.
• Answer-back (reply key) functionality.
• Volume controls.
• Upgrading I-Series panels.
Tip:For a brief description of all the 1-Series panels covered by this guide, including
product numbers, see
Table 1: I-Series user panels covered by this guide.
4.1 Powering up I-Series panels
4.1.1 Powering up panels with non-dis play key modules
When a panel with non-display key modules is connected to power, the keys on each key
module flash red, then green.
The keys then revert to their programmed colors (red for Talk or Talk-with-Listen, or
green for Listen).
Note:
If there is no communication with the Eclipse / Eclipse HX matrix, the keys will flash red
once per second until communication to the matrix is established.
4.1.2 Powering up panels with display key modules
When a panel with display key modules is connected to power, each of the display
modules will show the following message:
Clear-Com
Vx.x.x@2000
Where V.x.x.x represents the firmware version of the panel.
All keys will flash red, then green, and then display their programmed colors and labels if
there is communication with the matrix.
17
I-Series Panels User Guide
If there is no communication to the matrix, the display will show the following message:
No connection to Eclipse.
The keys will then flash red four times per second until communication to the Eclipse /
Eclipse HX matrix is established.
4.1.3 Powering up panels with a func tion key module
When an I-Series panel is connected to power, all of the keys on the function key module
will flash red, then green, and then revert to their programmed colors if there is
communication with the matrix.
Note:
If there is no communication to the matrix, the keys will remain dark until communication is
established.
4.2 Front panel controls and lights
Each key on any key module can be assigned as a talk, a listen, or a talk-with-listen in
ECS / EHX, the configuration software for the Eclipse / Eclipse HX matrix system.
For more information, see the ECS User Guide / EHX User Guide.
4.2.1 Non-latching keys
If the key is non-latched, the key remains active for talk or listen for as long as you hold
down the key. Release the key to return the key to its non-active state.
4.2.2 Latching keys
Latching allows you to lock a key into place, so that you can talk or listen hands-free.
Quickly tap a key to latch it for talk or listen. The key will glow brightly to indicate that it is
active. The key will stay latched until you tap it again to return it to its non-active state.
4.2.3 Active and Non-Active Keys
When you activate a key (by pressing or latching the key to talk or listen) the key is lit:
• Bright red, for a talk or talk-with-listen key.
• Bright green, for a listen key.
The key lights up bright red while you talk to the destination. When you press or latch an
assigned listen key, the key lights up bright green while you listen to the source.
A key that is not active (that is, a key that is not being used to talk or listen) is lit:
• Dim red for a talk or talk-with-listen key.
• Dim green for a listen key.

4.2.4 Alternative text key
The EHX software can cofigure an alternative text key called Show Alt Text to enable text
to change between normal text and alternate text.
The Show Alt Text key can be placed anywhere on the panel. This key can be placed on
all shift pages concurrently if desired to allow easy access.
When selected it will turn red, and the panel will show the alternate text.
Alias, VSM and PM text labels will override whichever state the panel is in.
One possible use of alternate text is to set up a dual language configuration on the panel,
for example to allow panels to display Arabic by default in a particular Middle Eastern
broadcast installation. English speakers could then select the Show Alt Text key on a
panel to see the English equivalents to the Arabic labels.

Bright green, when pressed /
latched for listen
Dim red, when pressed /
latched for talk.
There is no non-active listen
mode. A talk with listen key
always reverts to non-active
talk.
Another use could be that both the role name and user name could be configured for each
panel or beltpack port. This would allow panel users to see either the name or the role
depending on the Alt Text mode selected.
4.3 Using keys to indicate status
A key can be programmed to light up in a variety of ways to indicate its status.
Note:
If you decide to use one of the following options, it must usually first be set up in ECS /
EHX, the configuration software for the Eclipse / Eclipse HX system.
4.3.1 Call waiting light (ANSWR key)
When a s ource ca lls an I-Series panel, the ANSWR key will flash bright red at the call
waiting rate (four times per second). The source will be displayed in the call waiting stack
above the ANSWR key.
Audio from the source can be heard at the I-Series panel.
Note:
If any other key on the panel is assigned to the source this key will also flash at the call
waiting rate.
19
I-Series Panels User Guide
When you press the ANSWR key (or another key assigned to the source and flashing) to
talk, the ANSWR key and any other key assigned to the source stops flashing and is lit
bright red to indicate that the call is active.
When you release the key to take the call it becomes dim red to indicate that it is not
active.
Note:
Any other key associated with the call is also displayed dim red.
If a call is being answered when a second source calls you, the ANSWR key wil l not flash
at the call-waiting rate, but will continue to glow solidly bright red to indicate that:
• The key is active.
• The new call has been added to the call waiting stack on the ANSWR key.
If there is a key on the I-Series panel assigned to the source of the new call this will flash
bright red at the call rate. Audio from the stacked call will not be heard. Further calls will
also be added to the answerback stack until the limit of eight calls is reached.
To answer the second call, the first call must be terminated by releasing the key pressed
to answer the first call.
The first call will then be cleared from the call waiting stack when:
• The Answerback Auto Clear timeout threshold is reached.
• You press the CLEAR key.
The ANSWR key will then flash red at the call waiting rate to signal the next call is
waiting.
4.3.1.1 Answerback Auto Clear
The Answerback Auto Clear option sets the timeout before the current call is removed
from the answer-back stack, after the call has been ended. The Answerback Auto Clear
timeout option is set in ECS / EHX to a value between 1 – 60 seconds (or Off).
For more information, see the ECS / EHX User Guide.
4.3.2 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 lig ht opt ion is set in ECS / EHX. For more information, see the ECS / EHX User Guide.
4.3.3 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 of f-hook. The Eclipse / Eclipse HX matrix will cause each key
assigned to the telephone interface on every panel in the system to flash at the off-hook
rate whenever the telephone interface module (TEL-14) is active (off-hook) at one or more
of the panels.
20
I-Series Panels User Guide
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.
The telephone off-hook light is set in ECS / EHX. For more information, see the ECS /
EHX User Guide.
4.3.4 Radio-receiver active light
The light on a key will flash red once per second if a radio receiver is assigned to that key,
and the radio receiver is active.
The Eclipse / Eclipse HX matrix will cause each key assigned to the radio receiver on
every panel in the system to flash at the radio-receiver active rate whenever the radio
receiver is active at one or more of the panels.
If you press or latch a key that is flashing at the radio-receiver active rate, the key will glow
solidly red 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 requires:
• That the radio receiver is connected using a FOR-22 interface module.
• Enabling in ECS / EHX, in the Advanced Settings > Tallies options for the FOR-
22 interface module.
For more information, see the ECS / EHX User Guide.
4.3.5 Panel connected light
When the Station Connected Tally option is selected in ECS / EHX (under Advanced
Settings > Global Settings), the key assigned to a destination panel willflash red once
per second on your user panel, whenever that destination panel is connected to the
Eclipse / Eclipse HX matrix.
The Station Connected Tally is set up in ECS / EHX. For more information, see the ECS / EHX User Guide.
Note:
This option is primarily used when a destination panel is connected to the matrix using a
long-line link that might be active only at certain times.
4.3.6 Audio-presence light
If you assign a source to your panel 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 set up in ECS / EHX. For more information, see the ECS / EHX User Guide.

4.5 Answer-back (ANSWR)
None (solid)
With the answer-back feature you can reply to incoming calls from sources not assigned
to keys on your I-Series panel. You can also call out to destinations not assigned to keys
on your panel.
Tip: The answer-back feature is known as the Reply key on V-Series panels.
If a second unassigned source calls you while you are speaking to the first unassigned
source, the second call is placed in the answer-back stack, a group of up to eight waiting
calls that are answered in sequence.
All incoming calls can be answered at the answer-back keys, whether from sources with
assigned keys on the intercom panel 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.
