The 8945EDA/8945EDA-D configuration and monitoring can be also performed
using a web browser GUI interface or a networked Newton Control Panel when the
8900NET Network Interface module is present in the video frame (Gecko Flex
8900FFN) . Each of these interfaces is described below.
8900NET Module Information
Refer to the 8900NET Network Interface Module Instruction Manual for information on the 8900NET Network Interface Module and setting up and operating the
Gecko Flex 8900 frame network.
Note Upgrade software and instructions for the 8900NET can be downloaded from
the Grass Valley web site.
Newton Control Panel Configuration
A Newton Control Panel (hard or soft version) can be interfaced to the Gecko Flex
frame over the local network. Refer to the documentation that accompanies the
Newton Modular Control System for installation, configuration, and operation
information.
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 Not all module functions are available with the control panel, such as factory
default recalls.

If the module has not passed self-diagnostics, do not attempt to troubleshoot.
Return the unit to Grass Valley (see Module Repair on page 25).
The Electronic Circuit Breaker
The electronic circuit breaker works during a fault condition or an overcurrent
which stops the module.
Remove the module and replace it in the frame. If the problem persists, please refer
to the Grass Valley Customer Service.

The wideband serial SD/ASI or HD signal enters the module from rear BNC J9 or
J10 to an input amplifier. It is then equalized for the specified cable lengths in the
equalizer circuit.
The SDI driver modules feed the outputs. That ensures the rise and fall time adjustment regarding the signal format selection (SD/ASI or HD mode).
The main functions of the microprocessor include:
• Providing remote control and monitoring capability for the module (through
ethernet),
• Communicating with equalizer IC to monitor signal present status,
• Relaying module status through on-board LEDs, and
• Configuring module components at power up.

Power Supply
Functional Description
Power is fed from +12 V rails of the frame’s switching power supply. Each stage
of the module receives its own, separate, highly regulated and filtered power
source. The power input is protected by hot swap function.
