CHAPTER 1
Introduction
General Description
RTS®Cronus is a 32-port digital matrix intercom in 2RU (rack units). Based upon an advanced DSP architecture, Cronus has
the ability to link up to four units into a single 128 port matrix. Through the use of standard video coaxial cable, the maximum
distance between the first and last Cronus system can be 300 ft., and still appear as a single matrix. However, when using the
Fiber Option card, the distance is increased up to 15 kilometers nominally. When connected as a single matrix, the individual
Cronus controls remains autonomous and independent at each matrix for the highest reliability.
Features
USB Connectivity
Convenient front panel access, as well as traditional rear access for system
programming. Note, you may use either the front panel access or the rear panel access
at a time.
NOTE: The USB drivers for Cronus are installed with the AZedit software. You
can find the folder at C:\Telex\AZedit\V20606. The drivers are bundled in
version 2.06.06 or later.
Advanced DSP Digital signal processing designed to support audio signal processing on all 32 ports
(inputs).
Modular Architecture The modular architecture allows for port expansion from 8 to 32 ports giving each
user expandable systems in the field.
Redundant Power Supply Each chassis is powered by two power supplies, either of which can sufficiently power
all the equipment ALONE. This provides constant power and disaster recovery even
with the failure of one power supply.

Differences between Cronus and ADAM
Front and Rear Panel Controls and Connections
NOTE: For more information on a VOIP option card (RVON-C) for the Cronus, See “RVON-C RTS Voice Over
Network for Cronus” on page 37.
Cronus ADAM
Most practical for small to medium systems. Most practical for more complex systems because the
number of users is much higher.
In small to medium-sized broadcast company, Cronus would
be used like an ADAM. Uses ASIC technology
Cronus is scalable - can keep adding on to the original
configuration (up to four systems maximum) ADAM has both a redundant power supply and a redundant
Master Controller card.
Cronus has a redundant power supply.
Has one USB port with front and rear access.
Has capability for Ethernet connection
Cronus has individual data drives, meaning the address does
not need to be set at the keypanel.
FIGURE 31. Controls, Connections, and Cronus backcard. There are two Cronus backcards, an MDR backcard and an RJ-12 backcard. You can have
up to four backcards installed on Cronus. You can have any combination of backcards on the Cronus, too (for example, you can have two RJ-12
backcards and two MDR backcards.

3 Display Panel LCD display showing menu options.
4USB
Connection
There are two USBUSB connections on the Cronus; one on the front panel and one on the back
panel (J7). Cronus system can use the USB port connect with a PC. This allows for the most
flexibility when planning where to use the system. In a rack unit where the back is inaccessible,
or on a desktop where the back is accessible. Note, only one USB connector can be used at a
time.
5Power 1 &
Power 2
The power source indicator is a green LED light displaying that power is ON. The Cronus has a
redundant power source. This means there are two power supplies, so if power supply 1 fails,
power supply 2 will take over powering the system.
6Keypanel
Ports
(backcard)
One Cronus frame can have 32 ports through the use of either an RJ-12 backcard or an MDR
backcard. In all, the Cronus system supports a maximum of 128 ports available for keypanels.
You can also mix and match the backcards (for example, you can have 2 MDR backcards with 2
RJ-12 backcards on the same frame). The MDR backcard is primarily used to connect the three
compatible breakout panels, XCP-32-DB9, XCP-48-RJ45 and the XCP-48-Telco (See
“Breakout Panels” on page 83).
NOTE: Using an MDR backcard (9002-7770-005), you can utilize a DB-9 breakout panel (XCP-32-DB9 9000-7515-
000). One DB-9 breakout panel can support all four AIO cards within Cronus.
7 &
9LINE 1 and
LINE 2
Cronus has two power sources; a primary source (LINE 1) and a redundant power source (LINE
2). Both power sources are running at the same time, so that if the primary source fails the
redundant source will be able to power Cronus.
8 Fans There are two fans to cool the power supplies

Connectors
There are three ways to connect to a PC from the Cronus, through a DB-9 serial connection (10),
USB connector (11), or an RJ-45 (Ethernet) connection (12). There are six DB-9 serial ports,
however only five of the serial ports are used (J1, J2 [reserved], J3, J4, and J5) and one is
undefined (J6).
NOTE: J1 will always be connected to AZedit. For more information on AZedit baud rates, see
“DIP Switch Settings” on page 10.
13 DB-25
Connection General Purpose Input Output connection.
NOTE: The pin-out of this connection is not the same as Zeus, ADAM, or ADAM CS.
14 Coaxial and
Fiber
Connection
There are four coaxial or two fiber connections used to connect the frames together. See, figure
4B for the configuration illustration. Requires optional licensing firmware. Contact Telex
Customer Service for more information. When contacting Customer Service be sure to have the
MAC address for each unit. For information on how to obtain the MAC address, see “Finding
the MAC Address for Cronus” on page 30.

Determining the Master System From the Slave Systems
By default, Cronus is set to operate in stand alone mode. You will need a license file to link Cronus frames together. In order
to link 2 or more Cronus systems together, each must have the optional linking firmware installed. To purchase the firmware,
contact RTS sales.
Setting the master frame is done through the display panel menu, as well as cabling the frames together.
To configure the master frame, do the following:
1. From the display panel of the frame you want to configure, tap the ENC1 knob.
SET FRAME ID appears.
2. Tap the ENC1 knob once.
SLAVE appears.
3. Tap ENC1.
AUTO CONFIG appears.
4. Turn the ENC1 knob to select Auto Config, Frame ID 2, Frame ID 3, or Frame ID 4.
NOTE: Once you have set the Master frame you can set the rest of the frames by using autoconfig.
To cable Cronus, use the coaxial connectors located on the back panel (see Figure 32 on page 6). On the first frame connect
the two outside coax ports to the two inside coax ports on frame two. For more information, see Figure 35 on page 11. This
determines the master frame and the first slave. Repeat this procedure with the two remaining frames.
In the way the system is cabled, the master is indicated by the two inside coax ports left open. The two coax ports on the
master frame are used to connect to the matrix (ADAM system).
NOTE: Cronus has an internal mixing card, when not connected to an ADAM, that acts as a Master Controller. However,
when Cronus is connected to the ADAM, the Matrix system card acts as a slave to the ADAM controller(s).
DIP Switch Settings
Switch 1: AZedit Baud Rate
Default
Setting: CLOSED (38.4K; 38,400 kbps)
Description: Baud rate is a measure of the communications speed for a serial port. Baud is measured
in bits per second or bps. By default, AZedit is set for COM1 and 38.4K.
NOTE: The baud rate set with Switch 1 must match the baud rate set in AZedit. To
see what the baud setting is in AZedit, do the following:
1. Open AZedit.
The Keypanels/Ports screen appears.
2. From the Options menu, select Communications.
The Communications screen appears showing the AZedit session connection
configurations.
Settings OPEN: 9600 baud

Set Frame ID
In a single frame Cronus system, the frame will always be Stand Alone (or the Master frame). In a multi-frame system, the first
time Cronus is powered on, each frame will show as Frame 1 and will need to be configured, either manually or by autoconfig,
to designate which frame it is.
To set the FRAME ID, do the following:
1. Tap the ENC1 knob.
Configure appears.
2. Tap the ENC1 knob.
Frame ID appears.
3. Tap the ENC1 knob.
Set Frame ID displays.
4. Tap the ENC1 knob.
SLAVE Frame Set Slave ID displays.

5. Tap the ENC1 knob.
Auto Config displays. You can either have auto-config set the frame or you can manually set the frame ID by turning
the ENC1 knob to scroll through the Frame ID options.
6. Turn the ENC1 knob to scroll through the choices (Auto Config, Frame ID 2, Frame ID 3, or Frame ID 4).
7. Tap the ENC1 knob to make your selection.
IFB Program INs
I/O Gains
I/O Gain is the level of audio at which you hear and are heard. There may be occasions where you need to adjust the gain for
some specific intercom port. For example, a belt pack operator may want to monitor a party line, but at a lower level than the
normal intercom volume. Or, a beltpack operator may want to listen to the background music coming from some intercom
input port, but at a reduced level.
To set Gain from the front panel of Cronus, do the following:
1. Tap the ENC1 knob.
Configure appears.
2. Tap the ENC1 knob.
Frame ID appears.
3. Turn the ENC1 knob to I/O Gains.
4. Tap the ENC1 knob.
Select Port appears. There are 32 ports from which to select.
5. Turn the ENC1 knob to the port you want.
6. Tap the ENC1.
IN Gain and OUT Gain appears.
7. Use the ENC1 knob to adjust the IN Gain.
OR
Use the ENC2 knob to adjust the OUT Gain.
NOTE: You can change the gain levels in AZedit and see the results on Cronus almost immediately. For
more information on gain levels, see Figure 32 on page 6.
Vox Thresholds
Vox Threshold is the level of audio at which a channel becomes active. When the threshold is set, the microphone will not
turn on until the set audio level hits the set threshold. This prevents a channel from staying active when no one is around in a
high activity area.
To set and enable Vox Thresholds from the front panel of Cronus, do the following:
1. Tap the ENC1 knob.
Configure appears.
2. Tap the ENC1 knob.
Frame ID appears.
3. Turn the ENC1 knob to Vox Thresholds
Threshold appears.
4. Tap the ENC1 knob.
Select Port appears.
5. Turn the ENC1 knob to the port to be set.
You can set the thresholds on all 32 ports on the Cronus.
6. Tap the ENC1 knob to select the port.
7. Turn the ENC1 knob to set the threshold level (-127 dB to 0.0 dB)
