Preface
About This Manual
This manual describes the features of a specific 2000 Series module in the
Kameleon Media Processing System. As part of this module family, it is
subject to Safety and Regulatory Compliance described in the 2000 Series
frame and power supply documentation (see the 2000 Series Frames
Instruction Manual).

2041EDA Wideband Rear
Equalizing Distribution
AmpliÞer
Introduction
The 2041EDA Wideband Rear Equalizing DA provides basic equalization
and distribution of a single standard or high definition wideband signal
(4 Mb/s to 1.5 Gb/s) to eight outputs. The single module resides in any
rear slot of a Kameleon 2000 Series frame and is independent of any front
card for operation.
The features of the 2041EDA include:
•Auto equalization of both SD and HD signals,
•Accepts a wide range of standard or high definition input signal stan-
dards,
•Use of non-inverted outputs allow distribution of compressed signals
such as SMPTE 310M and DVB-ASI,
• Ideal for monitoring or distributing reclocked signals from adjacent
2000 modules, and
•Remote control and monitoring support.

Installation
Installation
Installation of the 2041EDA module is a process of:
• Placing the module in a rear frame slot, and
•Cabling signal ports.
The 2041EDA module can be plugged in and removed from a Kameleon
2000 Series frame with power on. When power is applied to the module,
LED indicators reflect the initialization process (see
Power Up
on page 10).
Module Placement in the 2000 Frame
There are twelve rear cell locations in the 3 RU frame to accommodate
either analog or digital modules. The 2041EDA rear module plugs into any
one of the rear slots of the Kameleon 2000 frame.
1.
Install the module by inserting it into any rear slot of the frame as
illustrated in Figure 1.
2.
Verify that the module connector seats properly against the midplane.
3.
Secure the module to the rear of the frame with the two screw locks on
either side of the back panel using a crossblade screwdriver.

Installation
Cabling
Cabling to the 2041EDA module is done on the BNCs on the rear of the
module. Refer to Figure 2 for a detailed illustration of the rear connections
referenced below.
Inputs
The 2041EDA will accept any of the video standards listed in the Input
specifications in Table 3 on page 14. Connect a video input to BNC J10.
Outputs
The 2041EDA outputs conform to the video standards listed in the Output
specifications in Table 3 on page 14.
Connect video destinations to any of the eight outputs at connectors J2 – J9.
Terminate any unused outputs.
Note
BNC J1 is not used on this module. On earlier versions of the 2041EDA
labeled with part number 671-5248-00, BNC J1 provided an output.

Power Up
Power Up
The on-board LED indicators are illustrated in Figure 3. Upon power-up,
the green PWR LED should light and the yellow CONF LED should illumi-
nate for the duration of module initialization.
Operation Indicator LEDs
With a valid input signal connected, the green on-board PWR LED,
SIG_PRES LED and the SIG LED (visible from the rear) should be on. Refer
to Table 1 on page 11 to see a complete list of possible operating conditions
and the resulting indicator status.
