KAM-HD-MULTI—Instruction Manual 11
Installation
Installation
Installation of the Kameleon HD module is a process of:
• Placing the dual-height KAM-HD-MULTI-UR or KAM-HD-MULTI-BR
rear module in a rear frame slot (no other rear modules can be used),
• Placing the media module in the corresponding front slot, and
• Cabling and terminating signal ports.
The Kameleon HD module can be plugged in and removed from a 2000
Series frame with power on. When power is applied to the module, LED
indicators reflect the initialization process (see Power Up on page 16).
Note The Kameleon HD must be installed in a 2000T1DNG or 2000T3NG frame
(2000NET and 2000GEN module installed) for access to a frame reference.
Module Placement in the 2000 Frame
There are twelve slot locations in both the front and rear of a Kameleon
3RU frame to accommodate Kameleon HD modules. The
KAM-HD-MULTI module requires a dual height rear module, either the
KAM-HD-MULTI-UR or the KAM-HD-MULTI-BR, that uses two rear
module slots allowing up to 4 modules per 3 RU frame, 2 in a 1 RU frame.
Dual-height modules can be placed in any rear slot as long as there is room
in the frame.
To install a Kameleon HD module set in a 2000 Series frame:
1. Locate a vacant slot in the rear of the 3 RU frame (Figure 1) or the
2000T1DNG frame (Figure 2 on page 12).

Quick Start Procedure
Quick Start Procedure
Follow the procedure below for a quick start method configuration for the
Kameleon HD module:
1. Go to the E-MEM web page (page 85) to select a preset audio
configuration if your audio needs match one of the four preset modes
explained in Audio Preset Configurations on page 23, or set the audio
configuration on the I/O Config web page (I/O Config Web Page on
page 43)
2. Go to the I/O Config web page (page 43) to name inputs and outputs.
3. Go to the System Config web page (page 47) to configure the input
video type (HD or SD), the video input rate, and the output timing
source. Split Screen controls are also available on this page as well as on
the HD Video Proc, SD Video Proc, and Color Correction web pages.
4. If not already connected, connect all input and output signals and
verify component and signal presence and condition on the Status web
page (page 38).
5. Go to the Functional View web page (page 50) to use the block diagram
links to configure each function in turn. Video processing must be
enabled on the System Config web page or with the Newton control
panel before adjustments can be made.
Note Next,Functional View,and Back links are provided to help you navigate
through a logical configuration sequence.
6. Use the Slot Config web page (page 92) to assign Slot Configuration
information such as slot name and asset number. Also link to the
2000NET module web pages to enable and disable Frame Health and
SNMP trap reporting.
7. Use E-MEM memory (page 85) to store or recall configurations as
necessary.
Note Always recall factory defaults after a software update.
8. Refer to Updating Software on page 97 for information on updating
software.

Configuration and Adjustments
Configuration and Adjustments
Kameleon HD configuration and monitoring can be performed using a web
browser GUI interface or a networked Newton Control Panel. This section
provides an overview of each of these controls along with the configuration
parameters available with each type of control device. It also provides an
overview of the audio configurations available on this module.
Audio Overview
There are a number of audio paths through the KAM-HD-MULTI module
that can be utilized depending on the type of audio application required.
This section gives an overview of the overall audio system and describes
the best uses of each of the audio paths and how to use the audio preset
configurations.
Audio Input Sources
Embedded audio in the SD or HD video input stream is automatically
demultiplexed and copied at the input of the module. Any or all of the eight
demuxed audio streams can be selected to be input streams to the audio
timing circuitry or bypass timing and processing completely, depending on
the type of audio and the application, and be sent directly to the AES out-
puts. The embedded audio can also be passed to the video output of the
module unmodified. Audio capabilities for different audio types are sum-
marized in Table 2 on page 20.
Up to eight external AES audio inputs can be connected to the rear module,
depending on the audio configuration set on the I/O Config web page (I/O
Config Web Page on page 43).
Eight audio sources, can be selected from the list of demuxed inputs
and/or the external AES inputs to make up the audio that can be multi-
plexed into the output video stream or output to external AES outputs
depending on the I/O configuration of the rear module and other module
configuration setups.

20 KAM-HD-MULTI—Instruction Manual
Configuration and Adjustments
KAM-HD-MULTI audio capabilities are summarized in Table 2 below:
The KAM-HD-MULTI module can use a rear module with either balanced
or unbalanced AES audio connectors. Eight audio streams can be con-
nected in the following configurations set on the I/O Config web page:
• 8 inputs/0 outputs – when the module is set for 8 inputs and no out-
puts, all eight audio connectors on the rear module become inputs for
external AES audio.
• 4 inputs/4 outputs – when the module is set for 4 inputs and 4 outputs,
4 audio connectors become inputs for AES audio and 4 audio connec-
tors become AES audio outputs on the rear module. Refer to the I/O
Config web page for the specific rear module connector numbers.
• 0 inputs/8 outputs – when the module is set for 8 inputs and no out-
puts, all eight audio connectors on the rear module become inputs for
external AES audio.
AES C/U/V Bits Pass Through
The control bits that are part of each subframe of AES data are defined as
C(Channel status), U (User), and V (Valid) bits and the Z bit, which carries
the start position of the AES block frame. For the control and status bits in
the CUV positions of each audio channel, and the Z marker for each stream
(pair of channels), there is a buffer on the module that handles the asyn-
chronous timebase slips between the input and output AES stream fre-
quency.
This buffer will drop or repeat an entire block (occurring every 192 sam-
ples) of CUV bits when the two timebases cross a block boundary rather
than drop or repeat individual bits from the block.
