ATTENTION ZEUS II USERS
The original Zeus manual ships with the Zeus II. This information sheet provides information that is
relevant to Zeus II users only. If the front of the unit does not have the Zeus II logo, the unit is an
original Zeus.
The Zeus II has the following additional features:
There are two power supplies and therefore two power cord connections
on the rear of the unit.
Simply plug in the power cords to turn the unit on.
There are two additional LEDs (PS1&2)onthefront panel which indicate
the status of the power supplies.
There is an additional connector (J28) which is used along with an RS-232
to RS-485 converter (not supplied) for trunking.
Below are figures that point out the Zeus II’s features. Located on the back of this sheet is a diagram
providing specific information regarding the connection of the Zeus II in a trunked system, as well as,
software configuration information regarding trunking.

If you don’t read anything else in this manual, at least
read these important notes:
•Make sure that the Zeus frame has adequate
ventilation. Allow at least 1 rack unit (1.75 inches, or
45 mm) of open space above and below Zeus at all
times during operation. Also, do not obstruct the
vents at both sides.
•The help file for ZEUSedit is intended to be your
primary document when learning how to use the
software. When viewing any main editing screen in
ZEUSedit press the F1 key on the computer keyboard
to get procedural information about how to use that
screen.
2 Introduction
This manual is divided into four main parts. There is a
general description and specification for Zeus starting on
page 9. Starting on page 13, are examples of how a Zeus
intercom system might be set up. We highly recommend
that you look through the example setup 1studio.zus that
starts on that page. It contains useful information about
component connections, and it also shows the most com-
monly used features of ZEUSedit. Cable wiring informa-
tion can be found starting on page 22. Finally, there are
general installation notes starting on page 25.
A Few Terms
For those users new to matrix intercom systems, or those
more familiar with TW (also called two-wire, party-line
or conference) intercom systems, it will be helpful to
define a few terms.
In TW intercom systems, the most normal configuration is
that of a single party-line, or conference, where all the in-
tercom users are interconnected on a single channel . The
users all hear one another at all times, and private conver-
sations between 2 individuals are possible only by hard-
ware changes (either manually or under system control).
Thus, in TW or party-line intercom systems, the conven-
tional usage of the term “channel” means a single connec-
tion between multiple intercom stations.
In Matrix intercom systems, the most normal configura-
tion is a point to point (P-P) connection, similar to a tele-
phone call: one user is connected to a single other user
and has a private two way conversation. Like the tele-
phone system, this is accomplished by having a dedicated
connection between each user (intercom station or key-
panel) and the matrix. In Zeus, this dedicated connection
is referred to as a channel or port. A Zeus channel (or
port) electrically consists of three pairs of wires, one pair
taking audio from the keypanel, one pair taking audio to
the keypanel, and one pair carrying 2-way control data be-
tween the matrix and keypanel. The important concept is
that EACH user or keypanel has its own dedicated chan-
nel back to the Zeus intercom matrix.
As will be shown later, through operating software, the
Zeus Intercom System can be programmed to create
party-lines or conferences, but even under those
conditions, each member of a conference has a unique
channel or port connection to the matrix.

3 Zeus General Description
Zeus is a versatile, 24-channel intercom signal router and
controller which you configure from an IBM compatible
PC. You use it to create sophisticated, small- to mid-size
intercom systems. Using ZEUSedit configuration soft-
ware for Windows®, you configure the channels to meet
the unique communication needs of each user of the sys-
tem. In the simplest application, for example, you can cre-
ate a two-way communication channel between a user on
channel 1 and a user on channel 2. This is called point-
to-point communication. Or, you can configure several
channels to talk and listen to each other in a conference.
That’s called a party line. There are other, more sophisti-
cated types of communication that you can set up as well.
See Table 1.
Zeus interfaces to all types of real-world audio devices.
Yet, at the same time, it is extremely compact. That’s be-
cause it interfaces to external devices using common ana-
log audio connections, while internally all signals are
routed as digital information using a technique known as
Time Division Multiplexing (TDM). The process is simi-
lar to what is used to create normal audio compact disks
(CD’s) except that the technology used by Zeus conveys a
significantly higher quality signal. You can route profes-
sional audio signals through Zeus without fear of signal
degradation. For each intercom channel, the analog input
and output gains are independently adjustable over a wide
operating range. As a result, many common devices can
be directly connected to channels: program audio signals
from an audio mixing console; audio output from a user to
a powered paging speaker or public address system; two-
way radios; 4-wire television camera intercoms etc. This
manual will also show you how to use RTS “TW” inter-
com equipment with Zeus.
Zeus provides additional level controls which let you
fine-tune the mix for individual users. If a user wants to
monitor one or more sources at reduced levels, while
monitoring all others at normal level, this can be accom-
plished using a separate level adjustment for each source
(called crosspoint level). If a user wants to monitor one or
more party lines at reduced levels while monitoring
point-to-point communications at a normal level, there is
a party line listen level adjustment for each party line.
Zeus is compatible with the complete line of RTS intelli-
gent keypanels and the TIF-951 Telephone Interface. Key-
panels give users the ability to independently talk and
listen to other channels, to party lines, or any of the other
types of communication. Some keypanels are also
equipped with a programming keypad, which allows the
user to change key assignments or dial-out through the
TIF-951 Telephone Interface. The TIF-951 can also let a
user call in over a phone line and use a touch-tone phone
to access any of the types of communication.
The Zeus GPI (General Purpose Interface) provides eight
control inputs and eight control outputs. You can use the
inputs to activate Zeus communications from external de-
vices such as paging systems or two-way radios. You can
use the outputs to control external devices from keypan-
els, such as two-way radios, paging systems, lighting sys-
tems, etc.
You can connect popular RTS digital matrix accessories to
Zeus via the accessory connector. The LCP-102 Level
Control Panel gives you direct inward access to many
ZEUSedit features from any convenient location in the in-
tercom system. It lets you access Zeus’analog input and
output gain adjustments. And, it lets you select program
input sources for IFB’s and set the program levels. You
can also use it to set up party lines and adjust the listen
levels for individual party line members. The UIO-256
Universal I/O frame lets you expand the quantity of GPI
inputs and outputs. Zeus is also compatible with the tradi-
tional digital matrix program assign panels (PAP’s).
Together, Zeus and ZEUSedit provide many communica-
tions and diagnostic tools which let you get the most out
of your intercom system. To get an idea of the real-world
possibilities of Zeus, we suggest that you take a look at
the sample intercom systems and descriptions on the fol-
lowing pages.
Getting Started, Zeus™ DSP Intercom Matrix 9
Point-to-point (P-P) Communication between two
channels. Each channel can com-
municate independently with
every other channel.
Party Line (PL) Communication between several
users in a conference. Zeus lets
you set each user as talker only,
listener only, or both talker and lis-
tener. 24 separate party lines can
be set up.
Isolate (ISO) A means for one user to isolate
another user for private communi-
cation. (Frequently used to tempo-
rarily isolate members of party
lines.) 24 separate ISO circuits
can be set up.
Interrupt Foldback
(IFB) with Adjustable
Dimming
A means for one user to dim (re-
duce the level of) an audio source
that a second user is listening to
and then talk over that source to
the second user. The amount of
dimming is adjustable from none
to full mute. 24 separate IFB cir-
cuits can be set up.
Special List (SL) A means for one user to talk and/or
listen to several other unrelated
users at once. (Useful for group
call or zone paging.) 24 separate
special lists can be set up.

5 About the Sample Configuration Files, 1studio.zus and 2studio.zus
5.1 Introduction
Included on the ZEUSedit installation disk are two sample
intercom system configuration files. We’ve also prepared
sample system diagrams to go along with the sample files.
We’ll provide a detailed explanation for the first sample
file. The second sample file does not include anything that
can’t be found in the first example. Rather, it is included
just to give you an idea of an alternate configuration.
To view the sample files, you will first need to install the
software if you have not done so already. Insert the
ZEUSedit disk into your computer and run the
setup.exe
program on the disk. Once the installation is completed,
go ahead and run ZEUSedit. Your computer does not have
to be connected to the intercom system yet. If you get the
message saying that ZEUSedit is unable to contact an in-
tercom, just click on OK. Let’s take a brief look at the
system diagram before examining the sample files.
5.2 1studio.zus Description
Figure 3shows a plan for a television news broadcast stu-
dio based on the sample configuration file 1studio.zus .
Note that the numbered callouts in the figure refer to cable
diagrams which can be found starting on page 22. We’ll
take a few moments for a general discussion of this system
plan, and then we’ll look at the ZEUSedit configuration file
to see how it can be accomplished. The system plan in Fig-
ure 3actually requires several sophisticated communication
techniques, all of which can be accomplished by Zeus with
a minimum of extra support equipment. First, there are the
standard keypanels used by the control and support person-
nel. The KP95-0 keypanels provide 15 talk keys, each of
which can be assigned (using ZEUSedit) to talk to anyone
in the intercom system. There is also a call waiting key for
incoming messages. Since the KP95-0 does not have dis-
plays for incoming caller identification, there is a designa-
tion strip holder above the talk keys, and there is a print
feature in ZEUSedit to print out designation strips.
The KP96-7 keypanels used by some personnel have all
the features of the KP95-0 keypanels, and also include 4-
character, alphanumeric key assignment displays which
automatically update whenever the key assignments
change. There is also a separate row of keys for independ-
ent listen activation. Additionally, the KP96-7 keypanels
have programming keypads which can be used to change
key assignments, to dial out on a telephone line through
the TIF-951 Telephone Interface, and to access certain di-
agnostic features.
Zeus can easily accommodate a variety of external de-
vices. In the example, a powered studio-paging speaker is
connected to a channel output and can be accessed from
any keypanel that has a key assigned to it. There are three
RTS Model 4020M earset circuits for the on-the-air news
talent (news anchors, weather person etc.). The earsets
permit the talent to monitor the broadcast via program
signals provided from the audio mixing console. For each
talent earset, the broadcast audio can be set to dim (reduce
in level) by a preset amount whenever that talent is receiv-
ing directions from the control room, and there are three
levels of priority for director keypanels to assure that the
proper personnel can communicate with the talent as
needed. There is a telephone interface which can interface
two phone lines to the intercom system and which permits
both incoming and outgoing call routing. The personnel
with the KP96-7 keypanels can dial out through the TIF-
951 Telephone Interface as previously mentioned.
The 4-wire internal intercoms in the studio cameras can
be directly connected to intercom channels, and there are
programmable analog input and output gain adjusters
within Zeus to compensate for nonstandard levels. These
gains can be adjusted using ZEUSedit. Or, an LCP-102
Level Control Panel (not shown) can be connected to pro-
vide direct access to this gain adjustment feature from any
convenient location. Figure 3also shows the use of RTS
“TW” intercom system components: The 2-wire, single-
channel, BP-318 belt packs used by some studio person-
nel interface to Zeus through SSA-324 converters. The
PS-15 power supply and TW5W splitters distribute oper-
ating power to the belt packs on the same wires that con-
duct the audio. ZEUSedit can place the cameras and belt
packs on a common party line, while also allowing key-
panel operators to isolate any member of the party line to
convey instructions without being interrupted by any
background chatter on the party line. ZEUSedit can also
be programmed so that the person directing is not both-
ered by callers while communicating instructions.
In any studio environment, there is always the possibility
of feedback when multiple intercom stations with speak-
ers are located in close proximity to one another. This po-
tential exists, for example, between the three keypanels in
the control room, and also between the three keypanels in
the Video Room. ZEUSedit has a special feature called
“Dim Tables” which lets you eliminate this problem
should it arise.
Let’s now take a look at the ZEUSedit configuration file
for
1studio.zus .
Getting Started, Zeus™ DSP Intercom Matrix 13

☞We’re going to make a suggestion now, which we
think is important when you are starting out with
ZEUSedit: put the help file on top and make use of it
while you are learning the system. Here’s how to put
the help file on top:
1. Press the F1 key on the computer keyboard. The help
file will open.
2. In the help file, click on the Options menu and point
to “Keep Help On Top”, then select “On Top”.
3. Now you can refer to step-by-step instructions in the
help file while performing the steps in ZEUSedit. If
the help file gets in the way, just re-size it, or move it
around, or minimize it when you are not using it.
☞By the way, whenever you press the F1 key, you’ll
usually get help for the main screen that you are
viewing in the background. Now, let’s get on with the
example help file.
1. Select File, Open, then browse to
c:\Telex\Zeusedit\Setups and open filename
1studio.zus .
2. The first thing that displays is a list of available
intercom resources. Skip past this now: click OK.
3. Now click on the Port Alpha button.
4. You should now be looking at the list of names for
intercom ports. A printout of this list is shown in
Table 3. This printout was obtained using the File,
Print command in ZEUSedit. You’ll notice that most
of the “Alpha” names in the list are the same as
names in parenthesis in the studio illustration. There
isn’t a lot of space on the keypanels to display long
names, so these Alpha abbreviations will be used
instead. ZEUSedit also lets you enter a longer
description for reference purposes. When you set up
your own intercom system, you’ll create a similar list
of names for intercom ports by selecting ports and
entering names. (For help on how to do this, press the
F1 key while viewing the port alpha list.) After you
have entered your names, you can print out a listing
and distribute it to keypanel operators.
5. Now you’ve seen where names for intercom ports are
entered. You can use these names when it’s time to
assign keys on keypanels. However, the studio plan
also calls for some names which aren’t in the list: for
example, TAL1, the talent 1 earset. That’s because

Table 3. A printout of the Port Alpha list for the
sample intercom setup file 1studio.zus

TAL1 is not an intercom port, it’s an Interrupt
Foldback (IFB). By the way, if you aren’t familiar
with this term, you could always get a description of
it from the help file. Click on the Search button, then
follow the instructions to search for IFB.
6. Let’s assume that you are familiar with the term, and
just move on to entering a name. Click the Other
Alpha button.
7. As you can see, there are several other types of
intercom resources, in addition to intercom ports, that
can be named.
8. To name an IFB, click on the IFB Alphas radio
button, then click OK to view the list of IFB’s.
9. Using the File, Print option, the IFB list has been
printed and is shown in Table 4. The sample printout
shows that there are 24 IFB’s available, as was also
indicated in the resource list that was presented when
you first opened the sample file, but only 3 of these
IFB’s are being used: one for each of the talent
earsets. Note: To see how to enter IFB names, press
the F1 key. When you are finished, move on to the
next step.
10. The only other type of Alpha that needs to be entered
is one for the studio production party line, which will
include the cameras, the floor manager, and the
lighting director. If you want to view the party line
alphas, just click the Other Alpha button again and
select the Party Line Alphas radio button.
11. Now you’ve seen where names are entered. The next
step in configuring an intercom system is to set up
any of the special communication types that are
needed. For example, the talent IFB’s have to be
configured so that they will operate correctly after
being assigned to intercom keys. To configure an
IFB, click on the IFB button.
12. You should now be viewing the IFB configuration
list. A partial printout of it is shown in Table 5. Note
that only the first three IFB’s have been configured:
one for each talent position. The list only provides a
summary of how the IFB’s are configured. If you
want to modify an IFB’s setup, you’ll have to select it
from the list and open the Edit IFB dialogue. While
viewing the IFB configuration list, you can get help
with setup by pressing the F1 key.

13. You should now have a good idea of how to name
things and also how to set up any special types of
communication that will be needed. Recall that the
1studio.zus example calls for a party line for the
studio production personnel (the cameras, lighting
director and floor manager). As with IFB setup,
which you start by pressing the IFB button on the
toolbar, you can start party line setup by pressing the
PL button. Table 6summarizes the types of
communication that you access with toolbar buttons.
Remember, you can get help setting up each of these
types of communication by clicking its toolbar button
and then pressing the F1 key on the computer
keyboard.
14. After you have named things and set up any
additional types of communication that you will
need, you can begin to assign keypanel keys to talk
and listen to the things that you have named. Let’s
show how this looks for the director keypanel in the
example setup file
1studio.zus . Press the KP button
on the toolbar. 15. The director’s keypanel is set up on intercom port
number 1, and this is the intercom port that appears
when you first click the KP button. See Figure 4.

Table 5. A partial printout of the IFB configuration list for the sample intercom setup file 1studio.zus
The IFB configuration list shows you at a glance all the information about an IFB. The IFB’s are numbered 001 through
024. These numbers will never change. The names that you enter using the Other Alpha button, as previously described,
appear in the Alpha column. Recall how an IFB operates: The talent (news anchor, weather person etc.) can hear the
broadcast program in his or her earset. For talent 1 (TAL1) this is the PGM1 program that is coming into Zeus on the inter-
com channel 21 input and is going out on the channel 21 output to the talent earset. Now suppose the director wants to tell
the talent near the end of a commercial break that he or she is back on in 10 seconds. The director could press a key as-
signed to PGM1 to do this, but then his voice would be mixed with the commercial audio and fed to the talent. It would be
difficult for the talent to understand what is being said. That’s where the IFB comes in. Instead of pressing a key assigned
to PGM1, the director presses a key assigned to the IFB TAL1. This causes the program audio level to be dimmed (re-
duced) by the amount indicated in the Dim? column. Now the director can be clearly heard. The normal program level will
be restored when the director releases the IFB key.

Figure 4. The keypanel setup screen for the director’s keypanel in the example file 1studio.zus
☞
Note: To get on-line help with keypanel setup, as well as some of the terms used below, press the F1 key while viewing
any keypanel’s setup screen in ZEUSedit.
Notice that all listen keys are assigned as “AF”. This is the auto-follow special function. This means that each listen key will
automatically follow, or have the same assignment as, the talk key directly beneath it. You’ll also notice that the “R” boxes are
checked above all key assignments. This means that the key assignments are restricted and cannot be changed by the key-
panel operator. It is fairly common in many intercom systems for these two features to be set up on all intercom channels right
from the start. The quick way to do this is to set it up on one keypanel and then copy and paste the settings to the keypanel
setup screens for the remaining channels. You use Paste Special to do this. Paste Special is discussed in the on-line help for
keypanel setup.
There are a few other things to note about the key assignments. You’ll notice that the first key, PROD, does not appear in the
illustration for 1studio.zus (Figure 3). That’s because this is the production party line and not an actual intercom station. You
can look at the production party line by clicking the PL button on the toolbar. If you do, you will note that the camera operators,
the lighting director, and both floor managers are assigned as members of the production party line. The director can talk to all
of them by pressing the PROD talk key.
You may also note that the names for the keys that are assigned to camera operators (1CAM, 2CAM, 3CAM) are spelled dif-
ferently than they appear in the 1studio.zus illustration. That’s because these keys are ISO keys and not point-to-point keys.
When the director presses the 1CAM key, for example, this will cause CAM1 to drop out of the production party line (PROD).
The director can then privately direct the camera operator. You can view the ISO setups by pressing the ISO button on the
toolbar.
☞
Typically in a television broadcast environment, it is the video operator who will use the camera isolates (if you look at the
keypanel setup for VID, you will see that the 1CAM, 2CAM and 3CAM keys are assigned) but the director can also access
them. Whenever one of these ISO’s is in-use by the video operator, the display above that key on the director’s keypanel
will flash slowly and continuously. This is a cue to the director that pressing the key may break in on a conversation that is
in progress.

16. Using the 1studio.zus example, we’ve now taken you
through virtually all the steps that are typically
required to set up an intercom system. First, you
name the intercom ports and any other types of
communication (IFB’s, ISO’s etc.) that you will
need. Then you configure any special types of
communication that you have named. Then you
assign the things you’ve named and configured to
intercom keys on keypanels. There are still one or
two more things that might be required: you may
need to set up one or more dim tables, and you may
need to adjust the input or output gains for some
intercom channels. We’ll finish with a brief
discussion of these two topics.
17. In the 1studio.zus example, the director, the assistant
director, and the technical director are all located in
the same room. Their keypanels are fairly close
together, and the keypanels all have some common
key assignments. For example, they all have a key
assigned to talk to PROD, the production party line.
(You could check this by clicking the KP button on
the toolbar, and then selecting each of the three
intercom ports in turn to view the key assignments.)
Now suppose that both the director and the technical
director have their PROD talk and listen keys
activated, and the director is speaking. This will be
heard at the technical director’s keypanel speaker.
And, if the director’s microphone picks up the
speaker audio (which is actually his own voice) and
reamplifies it, this could cause feedback. To prevent
this potential problem, a dim table has been set up.
To view this dim table, click the Dim button on the
toolbar.
18. Figure 5shows the dim table that has been set up for
the control room keypanels. While viewing this
screen, press the F1 key to get help with dim table
setup.
19. To finish, we’ll discuss the analog gain adjustment.
In the 1studio.zus example, one possible use of this
adjustment might be to adjust the audio output levels
to the camera intercoms. These devices may be
operating at a different audio level than the intercom
system. As a result, any communications to the
camera operators from any keypanel might sound too
loud or soft. You adjust audio input and output gain
from the System menu (Figure 6). As with most of
the setup tables, you can get help with analog input
and output gain adjustment by pressing the F1 key
while viewing the table.
18 Getting Started, Zeus™ DSP Intercom Matrix
Figure 5. A partial view of the control room dim table for the example intercom system 1studio.zus.
All keypanels that are located in the control room have been assigned as members of the dim table, and the amount of dim-
ming has been set at -1dB; a fairly small amount. Whenever one of these keypanel operators activates a key assignment, the
volume will be reduced by 1 dB at any of the other keypanels that are listening to the same destination. Note: The name “Con-
trol Room Dim” was assigned using the Other Alpha button on the toolbar.
