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.

Introduction

Differences between Cronus and ADAM
Front and Rear Panel Controls and Connections
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.
TABLE 1. 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 ny combination of backcards on the Cronus, too
(for example, you can have two RJ-12 backcards and two MDR backcards.
1 ENC 1 This knob allows you to select a menu item, scroll through menus or exit out of the display menu.
2 ENC 2 This knob allows you to select a menu item, scroll through menus or exit out of the display menu.
NOTE: Only when you are in the crosspoint status menu do the left and right knob perform separate functions. The Right knob
adjusts the output port, while the Left knob adjusts the input port.
3 Display Panel LCD display showing menu options.

Front and Rear Panel Controls and Connections
4 USB 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.
5 Power 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 41).
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 & 9 LINE 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

Connections, USB
Connector and RJ-45
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 8.
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 26.

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 2 on page 4). On the first frame connect the
two outside coax ports to the two inside coax ports on frame two. For more information, see Figure 5 on page 9. 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
CLOSED: 38.4K baud (default)
Switches 2-7 Not Available
Switch 8 Reserved. Must be kept in OPEN position.

Cronus System Diagram and Frame Cabling
Cronus System Diagram and Frame Cabling
TABLE 5. The Cronus Intercom System has four frames, one Master and three Slave stations (see system diagram on left)
connected via coaxial cables (see cabling diagram at right). Each frame can support up to 32 ports, and each system can
have a maximum of 128 ports (all four frames available). By adding a connection to a Cronus Bus Expander (CBX) on
ADAM, Cronus can be linked to other Cronus Systems, increasing the number of available ports able to communicate with
one another.

I/O Gains
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.

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

1. Tap the ENC1 knob.
Configure appears.
