GETTING STARTED
The CDT100 MK3 four input Dante interface is the ideal interface for adding
microphone inputs to a Dante system.
Adding touch switches, motorized microphone controls, and LED indication
to your system is simplified with Touch Switch and ARM-C ports. The small
form factor allows the CDT-100 MK3 to be installed in close proximity to the
microphones, minimizing interference-prone analog wiring.
Up to 6 CDT100 MK3 units can be installed in a daisy chain configuration,
further reducing the amount of cabling needed.

6

Pins 1, 5, and 8 are Switch Logic Inputs (GPIOs). These are
pins that the DSP or control system reads the Hi/Low status
and reacts as programmed (3.3V, switch for Clockaudio
control devices is Pin 5)
Pins 2, 6, and 7 act as GPI/O Outputs or relays/contact
closures, that ground to Pin 3, the common ground.
PIN 3 is the Common Ground.
PIN 4 is the 12V supply for LED power and switch operation.

13
CONNECT ARM-C CONTROLLER
The ARM-C port connects to an optional ARM-C controller for use with boundary
mics that have motorized retraction features.
Connect the ARM-C device to the port labels ARM-C with a standard RJ12 cable.
Use Clockaudio Control Panel application to test ARM-C functionality.
CONNECT TO A DANTE NETWORK
Each Dante network port provides up to four channels of input to a Dante
network, and two channels of audio output from a Dante network on a single
network cable.
When using a single CDT100 MK3 (or when connecting multiple CDT100
MK3 units directly to a switch in a non-daisy chain configuration), connect one of
the CDT100 MK3 Dante Ports directly to an open port on a Dante network switch.
The second Dante Port is used for Daisy Channing CDT100 MK3 networked
audio (see Daisy Chaining configuration for details).
NETWORK CABLE RECOMENDATIONS
Shielded CAT5e or CAT6 cables are recommended for Dante Network
connections. Shielded connections will minimize interference from
lighting and other sources.

14
CONNECT POWER
Connect a 12VDC power supply (sold separately). If using multiple CDT100
MK3 devices in a daisy chain configuration, see power considerations in the
Daisy Chaining section of this manual.
Attach the power supply to the power input jack. The power light on the front
should illuminate green to indicate normal operation.There may also be
some activity on the CDT100 MK3 Dante port LED indicators.
When not connected, both LEDs will remain off. If an active connection is
made, the green LED will illuminate and blink to indicate network activity.
The second LED will illuminate yellow to indicate the network speed (on is
1Gbit, off is 100 Mbit).
DAISY CHAINING CDT100 MK3 UNITS
A unique feature of the CDT100 MK3 is the ability to connect up to 6 units
in a daisy chain configuration. Both power and network data can be daisy
chained, resulting in decreased installation costs and simplified installs.
DATA DAISY CHAINING
To connect multiple CDT100 MK3 units in a daisy chain, connect the first
unit directly to the Dante network as explained above. Connect one of the
Dante Ports on the second device to the open Dante Port on the first device.
Each additional device (up to six) can be connected in the same manner.
POWER DAISY CHAINING
Connect the first CDT100 MK3 to an adequate power supply. To supply the
proper power to each of up to 6 devices, one of the CDT100 MK3 devices
in the chain must be connected to an external power supply that provides
12VDC and appropriate voltage (see chart in the Power Considerations
section for approximate requirements).
Use the OUTPUT terminal on the first device to daisy chain power to the
INPUT terminal on the second device. Connect the first device positive
(+) OUTPUT terminal to the positive INPUT terminal on the second device.
Connect the first device negative (-) terminal to the negative INPUT terminal
on the second device.

15
POWER CONSIDERATIONS:
The number of devices supported in a daisy chain configuration will be
determined by the power supplied to the system. Ensure a proper power
supply is used when connecting multiple devices.
Single CDT100 MK3: 12VDC at ≈4W*
Two CDT100 MK3 units: 12VDC at ≈8W*
Three CDT100 MK3 units: 12VDC at ≈12W*
Five CDT100 MK3 units: 12VDC at ≈20W*
Six CDT100 MK3 units: 12VDC at ≈24W*
* CDT-100 MK3 units only, no additional connected devices
Additional power requirements must be considered when using Touch
Switch ports with the CDT100 MK3. Each Touch Switch that is connected
will increase power requirements. When using multiple units in a daisy
chain configuration, please consider the total system power requirements.
TS PORT POWER REQUIREMENTS
Each Touch Switch port with a connected LED may require between 1 watt
and 3.5 watts depending on the Touch Switch configuration. When using
multiple Touch Switches, this number must be multiplied by the number of
connected Touch Switches.

CDT100 MK3 DANTE AUDIO SETUP
Configure the audio routing via the Dante Controller (available for Windows
PCs and Mac OSX).
Each CDT100 MK3 will appear on the Dante network with a unique name for
identification and routing. The default naming will be CDT100MK3-######
with the # replaced by the last six digits of the device’s MAC address.
The CDT100 MK3 is capable of sending 4 separate channels of audio (mic
inputs) over a Dante network and receiving 2 channels of audio (outputs)
form the Dante network. Using the Dante Controller, each available channel
can be routed to a connected DSP unit, mixer, or mixing amplifier.
CONFIGURING IP ADDRESSES
By default, each device in the Dante Network will automatically be assigned
an IP address.
If the IP addresses are not configured properly, the CDT100 MK3 may
show up in the Dante controller, but input and output channels may not be
available for routing.
DOWNLOAD the Dante Controller from Audinate at www.audinate.com.
Dante Controller is a free software application that enables you to route
audio and configure devices on a Dante network.

CLOCKAUDIO CONTROL PANEL
The Clock Audio Control Panel for Windows computers provides additional
functions for setting up the CDT100 MK3. This section describes some of
the basic controls but is not intended to be exhaustive. Please consult the
Clockaudio Control Panel manual for additional functionality.
The Clockaudio Control Panel application will need to communicate to
the CDT100 MK3 over the network. All Dante devices will be discovered
regardless of the IP address setup on the PC, however, communication with
the CDT100 MK3 Windows application requires a compatible IP addresses.
By default, the CDT100 MK3 will receive a dynamic IP address. If there is
no DHCP server to assign an IP address, the device will self-assign an IP
address. This IP address will always start with 169.254.x.x.
