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
tion Manual
).

2041RDA Wideband Rear Reclocking DA
Introduction
The 2041RDA Wideband Rear Reclocking Distribution Amplifier provides
high HDTV distribution density with eight non-inverting outputs. It has
auto-detect and reclocking capability at all SD (standard definition) and
HD (high definition) data rates. The reclocking circuit can be bypassed to
distribute compressed signals down to 4 Mbps. The 2041RDA can be
removed from the rear of the frame without powering down the frame
(hot-swappable).
The 2041RDA features include:
• Eight outputs
•Module is hot-swappable
•Automatic data rate detection
•Reclocks at 143 Mbps, 177 Mbps, 270 Mbps, 360 Mbps, or 1.5 Gbps
•Distributes transport streams in bypass mode
•Auto-equalizing up to 100 meters for reclocked HD video or a bypassed
carrier and 300 meters for reclocked SD video
• Supports networked control and monitoring

Installation
Installation
Module Placement in the 2000 Frame
Installation of the 2041RDA module is a process of:
• Placing the 2041RDA rear module in the selected rear frame slot, and
•Cabling signal ports.
The 2041RDA 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
There are twelve rear media module slot locations in the 3 RU frame to
accommodate either analog or digital modules (see Figure 1). The
2041RDA is a rear media module that can be plugged into any of the 12 rear
media module slots.

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.
All cabling to the 2041RDA module is done on the connectors on the
module at the back of the 2000 frame. Refer to Figure 3 on page 10 for a
detailed illustration of the rear connections referenced in the steps below.
Connect an HD or SD video input to BNC J10. The 2041RDA module will
accept any of the serial digital component video signals conforming to the
following SMPTE formats:
•SMPTE 292M
• 259M (143 Mbps, 177 Mbps, 270 Mbps, 360 Mbps)
•4 Mbps to 1.5 Gbps (tested with PN20 pseudonoise sequence ratio,
maximum 19:1)
•SMPTE 310M

Configuration
Local On-board Module Configuration
The 2041RDA can be configured locally using on-board jumpers or
remotely using the 2000NET network interface.
The following parameter options can be set on the 2041RDA module:
•Remote control and monitoring lockout (on-board only),
•Automatic signal locking and reclocking mode,
•Reclock/Bypass mode (enabled/disabled reclocking), and
•Manual input signal selection mode (remote only).
The 2041RDA module can be configured locally using the jumpers shown
in Figure 5 on page 14. The CONF LED indicates status of the configuration
process.
Configuration
These components perform the following:
• Jumper J24 – sets control mode for Local only or Remote and Local.
• Jumper J25 – enables or disables the reclocking function.
• CONF (configuring) LED – when on, indicates the module is initializing or processing configuration information.
Remote Control Jumper
When the jumper is placed across pins 2 and 3 of jumper block J24, module
settings are changed from the on-board jumpers only. To have both Local
and Remote access, set the jumper across pins 1 and 2.

Troubleshooting
Service
The 2041RDA 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 as directed by Grass Valley 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:
•Check frame and module power.
• If module power is not present, check fuse F1 (see Figure 11).
Module Repair
•Check for presence and quality of input signals.
•Verify that source equipment is operating correctly.
•Check cable connections.

Input and Output Processing
The input section has a parallel input path from the passive rear input
module for SD (standard definition) and HD (high definition) signal equalizing and reclocking. The input section can also bypass the signal through
the HD EQ and HD Reclocker directly to the output amplifiers. The output
amplifiers drive eight equal-phase outputs.

Microprocessor and Input Selector
The primary purpose of the microprocessor is to provide remote control
and monitoring capability for the 2041RDA. It receives signal present,
signal lock, and speed detection signals from the equalizer and reclocker
circuits. Using this information, local jumper settings, and remote control
commands, the microprocessor selects the internal signal path and gives
feedback through the LEDs and remote control bus.
