In order to configure an CDT100 both to set up its internal parameters and also setup audio routing, the PC will need to be able
to communicate with it over the network.

While all Dante devices will be discovered regardless of the IP address setup on the PC, communication can only occur if the PC
and the device have compatible IP addresses.

By default, CDT100 is set to get a dynamic IP address. As with all Dante devices, if the CDT100 device does not find a DHCP server
to retrieve an IP address from, it will give itself an automatic private IP address (APIPA) instead.

An APIPA is always in the range 169.254.x.y.

To ensure communication, the PC can either be set to get a dynamic IP address, or be given a static IP address in the range
169.254.x.y. The PC may require a restart for the changes to take affect.

Further information on IP setup for an audio system using Dante can be found in the FAQ’s on the Audinate website
(https://www.audinate.com/resources/faqs).

CDT100 User Manual

Clockaudio 2015

4 – Device Configuration

There are two parts of the device that require software to setup:
1. The audio routing.
2. The configurable features of the device itself.
The audio routing should be carried out using Audinate’s Dante Controller, available for Windows and Mac OS X from the Audinate
website www.audinate.com along with instructions on how to use the software and setting up routes on a Dante network.

Dante Controller is a free software application that enables you to route audio and configure devices on a Dante network.
With automatic device discovery, one-click signal routing and user-editable device and channel labels.
See the overview link for more details on

Dante audio networking

4.1 - IP Address Setup

Important Notes:



When using Dante controller, the CDT100 will be shown using a default device name of CDT100-###### where ‘######’ is the
last six characters of the devices MAC address.



Failure to correctly configure IP addresses will not allow an CDT100 device to correctly authenticate in the software and while it
will show up in Dante Controller. The input and output channels won’t be visible and routing of audio to and from the CDT100
will not be possible.

Features:



View all Dante-enabled audio devices and their channels on the network..



View and edit device clock and network settings



Route audio between devices, and view the state of existing audio routes



Rename devices and channels using your own friendly names



Customize the receive latency (latency before playout)



Save and reapply audio routing presets



Edit presets offline, and apply as configurations for new network deployments



Change sample rates and clock settings



View multicast bandwidth across the network



View transmit and receive bandwidth for each device



View device performance information, including latency stats, clock stability stats and packet errors



View comprehensive, configurable event logs

4.2 – Device Identification

The device identification feature allows the user to see which device is physically being configured.

When the identify feature is active, the power LED on the active device will flash.

The Identify check box shows the state of the device identify feature. If the box is checked, the feature is active on the active unit.

If the check box is clear, the identify feature is inactive.

To change the state of the feature, simply click in the Identify check box to toggle its state from off to on or on to off.

The identify function will continue to operate until the function is turned off via the user interface or the device is powered down.

5 – Dante Daisy Chaining

Overview:

A unique feature of the CDT100 is its ability to allow daisy chaining of devices. This allows CDT100 units in close proximity to one
another to utilize a single home run of Ethernet cable back to the switch thus saving on installation costs.

Daisy chaining simply requires the new device be connected to the spare Ethernet port of the last CDT100 device in the current
chain.

Not only can the Ethernet connection be daisy chained, power can also be daisy chained too by connecting the daisy chain power
output on the last active device to the daisy chain power input on the new device.

The number of devices that can be daisy chained is limited.

The

maximum

that can ever be daisy chained is

6 devices

in a single chain.

Beyond that the number of switch hops may cause audio problems due to excessive latency and increased clock jitter.

The other limitation is the power supply, if power is also being daisy chained from device to device.

Standalone:

If power is supplied to the first device via a standalone supply, the supplies maximum power output determines the number of
devices it can support (assume 4W @ 12V DC per device).

To daisy chain a device to another CDT100:



Connect an Ethernet cable from the data only port of the CDT100 to one of the ports of the CDT 100 to be chained to supply
the network information.



To chain the power, connect the “Link out” connector to the “Link in” connector on the CDT100 to be chained.



A third unit could be chained by connecting it in the same way to the second unit and so on.

Network Configuration Note

If the CDT100 units are installed in a networked daisy-chain topology, it is highly recommended to only configure unicast flows
from each of the CDT100 devices' Dante transmitters.

The addition of multicast flows along the daisy chain can overwhelm the switches in the chain with unnecessary multicast audio
traffic resulting in potential latency and network clock synchronization issues, especially on the units installed at the end of the
daisy-chain network segment.

Additionally, if there are a significant number of multicast audio flows configured on the Dante network, it is recommended that
the core network switches that interface to the daisy-chained CDT100 network segments be configured with the appropriate
IGMP settings to shield the CDT100 chain from unnecessary multi-cast audio traffic.

CDT100 User Manual

6 – Mounting

Installation of the CDT 100 is very straight forward.
It is recommended that the unit be secured to a flat surface with a screw through each mounting flange.
Dimensions for mounting are show in the Figure 9 below.
Use a No. 6 screw of a type and size that is applicable to the surface to which the CDT100 will be attached.

All connections to the CDT 100 should be made before the power is applied.



Attach any audio sources that will be used to the inputs. The inputs are balanced so be sure to check what output type the
source to be connected uses in order to find how to connect it correctly . (see Hardware Connections section).

When powering, using an optional external supply:



Attach either Dante I/F port to a spare port on the Dante network switch using a CAT 5 cable.



Attach the power supply to the power input jack and then power up the external supply.

If all steps are performed correctly, the power light on the front should be lit. There may also be some activity on the CDT 100
Dante I/F LED indicators.

With no Dante network, both LEDs will remain off.

If an active connection is made, both LEDs will come on and if there is network activity, the yellow LED will flash

Simple Windows Name:

Clock_Audio_CDT100_Module

Summary:

This module provides control and feedback of the Clockaudio CDT100 via UDP. It also provides true feedback.

General Notes:



Pulse the Initialize input before performing any other operations.



The module utilizes a “Heartbeat” to maintain communication with the CDT100. This heartbeat will begin once preliminary
initialization is complete.



Should a heartbeat response not be received, the module will attempt to send the heartbeat two more times in succession.



If neither of these responses are received, the module will consider communication with the CDT100 to be broken, it will clear
all existing data and output signals, and will attempt to re-establish communication with the CDT100 every 10 seconds.



Once communication has been re-established, the module will automatically re-initialize.



The module will automatically subscribe for available unsolicited feedback with the CDT100 upon initialization.

Crestron Hardware Required:

3 Series Compatible only

Setup of Crestron Hardware:



Connect Crestron 3-series processor via Ethernet port of same network that CDT100 is on.



Configure IP address of both Crestron and CDT100. (Ensure subnet settings match).
