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 standards,
•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.

2.
3.
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).
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.
Verify that the module connector seats properly against the midplane.
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.

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.
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.
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.

Operation Indicator LEDs
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 illuminate for the duration of module initialization.
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.

Configuration and Monitoring
Configuration and Monitoring
The 2041EDA has no configuration requirements. There are no local
jumpers or controls on the 2041EDA module.
Remote Monitoring
2041EDA monitoring can be performed remotely using the 2000NET interface (see Figure 4). This section describes the GUI access to the module configuration and monitoring functions. Refer to the 2000NET Network
Interface Module Instruction Manual for information on setting up and
operating the 2000 frame network.
Note
The 2000 modules can be addressed by clicking on a specific module icon
in the frame status display or on a module name or slot number in the link
list on the left.
Figure 4. 2000NET GUI
The Links section lists the frame and its current modules. The selected link's Status
page is first displayed and the sub-list of links for the selection is opened. The sub-list
allows you to select a particular information page for the selected device.
The physical appearance of the menu displays shown in this manual represent the use of a particular platform, browser and version of 2000NET
module software. They are provided for reference only. Displays will differ
depending on the type of platform and browser you are using and the version
of the 2000NET software installed in your system.

Service
Power-up Diagnostics Failure
Troubleshooting
The 2041EDA modules make extensive use of surface-mount technology
and programmed parts to achieve compact size and adherence to
demanding technical specifications. Circuit modules should not be serviced in the field unless otherwise directed by Customer Service.
If the module has not passed self-diagnostics, do not attempt to troubleshoot. Return the unit to Grass Valley (see Module Repair ).
If your module is not operating correctly, proceed as follows:
Service
•Check frame and module power. If power is not present, check the fuse
on the module as illustrated in Figure 6.
•Check for presence and quality of input signals.
•Verify that source equipment is operating correctly.
•Check cable connections.

Output Processing
Driver circuits drive each of the eight serial digital outputs to the rear BNCs
J2 through J9. These outputs are non-inverting and are in-phase with each
other.
Power Supply
Power is fed from +24 V rails of the frame’s switching power supply. Each
