Configuration and Monitoring
Remote Configuration and Monitoring
Configuration and monitoring can be performed using a web browser GUI
interface or a networked Newton Control Panel when the 2000NET
Network Interface module is present in the video frame. Each of these
interfaces is described below.
2000NET Module Information
Refer to the 2000NET Network Interface Module Instruction Manual for information on the 2000NET Network Interface module and setting up and
operating the Kameleon 2000 frame network.
Newton Control Panel Configuration
A Newton Control Panel (hard or soft version) can be interfaced to the
Kameleon 2000 Series frame over the local network. Control panel access
offers the following considerations for module configuration and monitoring:
•Ability to separate system level tasks from operation ones, minimizing
the potential for on-air mistakes.
•Ability to group modular products—regardless of their physical locations—into logical groups (channels) that you can easily manipulate
with user-configured knobs.
•Update software for applicable modules and assign frame and panel IP
addresses with the NetConfig Networking application.
•Recommended for real-time control of module configuration parameters, providing the fastest response time.
Note
An example of the Newton Configurator is shown in Figure 10 on page 17.
Not all module functions are available with the control panel, such as factory
default recalls. The available control panel controls for the module are listed
in Table 3 on page 14.

The web browser interface provides a graphical representation of module
configuration and monitoring.
Use of the web interface offers the following considerations:
•Provides complete access to all module status and configuration func-
tions, including factory parameter and name default recalls, slot configuration, and SNMP monitoring controls.
•Web access will require some normal network time delays for pro-
cessing of information.
•Configuration parameter changes may require pressing the

Status Monitoring
Status Monitoring
This section provides a summary of status monitoring and reporting for a
Kameleon 2000 Series system. It also summarizes what status items are
reported and how to enable/disable reporting of each item. There are a
number of ways to monitor status of modules, power supplies, fans and
other status items depending on the method of monitoring being used.
2000 Frame status will report the following items:
•Power supply health,
•Status of fans in the frame front cover,
•Temperature,
•Module health, and
•Frame bus status.
Module health status will report the following items:
•Internal module state (and state of submodule or options enabled)
including configuration errors (warning), internal faults, and normal
operation (Pass).
LEDs
•Signal input states including valid/present (pass), not present or
invalid (warning), not monitored, and not available (no signal inputs).
•Reference input states including locked/valid (pass), not
locked/invalid (warning), and not monitored.
•Signal output states with reporting functionality (reference output).
LEDs on modules in the frame and on the front of the 2000 frames indicate
status of the frame and the installed power supplies, fans in the front
covers, and modules.
When a red FAULT LED is lit on a frame front cover, the fault will also be
reported on the 2000NET or Frame Monitor module. The LEDs on the front
of these modules can then be read to determine the following fault conditions:
•Power Supply 1 and 2 health,
•Fan rotation status,
•Frame over-temperature condition,
•Frame Bus fault (2000NET only), and
•Module health bus.
282030RDA Instruction Manual
In general, LED colors used on the frame and modules indicate:
•Green – normal operation, (Pass) or signal present, module locked.
•Yellow – On continuously = active condition (configuration mode or
communication), flashing in sequence = module locator function.
Status LEDs for this module are described in LEDs on page 28. LEDs for the
2000NET module are described in the 2000NET Network Interface Instruction Manual.
Frame Alarm
Connection and use of the Frame Alarm (3 RU frames only) is covered in
detail in the 2000NET Network Interface Instruction Manual.
Web Browser Interface
Status Monitoring
When the 2000NET module is installed in the frame, a web browser GUI
can indicate frame and module status on the following web pages:
•Frame Status page – reports overall frame and module status in graph-
ical and text formats.
•Module Status page – shows specific input and reference signal status
to the module along with enabled options and module versions.
•A Status LED icon on each web page to report communication status
for the frame slot and acts as a link to the Status page where warnings
and faults are displayed (2000NET version 3.0 or later).
In general, graphics and text colors used indicate the following:
•Green = Pass – signal or reference present, no problems detected.
•Red = Fault – fault condition.
•Yellow = Warning – signal is absent, has errors, or is mis-configured.
•Grey = Not monitored (older 2000 module).
•White = Not present.
Status reporting for the frame is enabled or disabled with the configuration
DIP switches on the 2000NET module. Most module status reporting items
can be enabled or disabled on individual configuration web pages.
2030RDA Instruction Manual29
Status Monitoring
SNMP Reporting
The Kameleon Series system uses the Simple Network Monitoring Protocol
(SNMP) internet standard for reporting status information to remote monitoring stations. When SNMP Agent software is installed on the 2000NET
module, enabled status reports are sent to an SNMP Manager such as the
Grass Valley’s NetCentral application.
There are both hardware and software report enable switches for each
report. Both must be enabled for the report to be sent. Software report
switches are set on the 2000NET Configuration page for the Frame, the
2000NET module, and each module slot. Refer to the 2000NET Network
Interface Instruction Manual for installation instructions.

Input and Output Processing
The input section receives SD (standard definition) video from the passive
rear input module and sends it to signal equalizing and reclocking circuits.
The input section can also bypass the signal through the Input Selector circuits to the output amplifiers. The output amplifiers drive nine equal-phase
outputs on the passive rear module.
Microprocessor and Input Selector
The primary purpose of the microprocessor is to provide remote control
and monitoring capability for the 2030RDA. 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.
