Preface
About This Manual
This manual describes the features of 8945EDA and 8945EDA-D front modules
and their corresponding rear module (8900WE-R) in the Gecko Flex frame. As part
of this module family, it is subject to Safety and Regulatory Compliance described
in the Gecko Flex frame documentation.

8945EDA and 8945EDA-D Equalizing Distribution Amplifier
Introduction
The 8945EDA or 8945EDA-D Wideband Front Equalizing DA provides basic
equalization and distribution of a standard definition or high definition signal up to
eight outputs over 75 ohm coaxial cable in SD/ASI or HD.
The two models, 8945EDA (single) and 8945EDA-D (dual) must be installed in a
Gecko Flex frame.
Features
The features of the 8945EDA and 8945EDA-D include:
• Auto cable equalization for up to 330m of cable in the case of SD and ASI
signals and for up to 125m of cable in the case of HD signals,
• Accepts a wide range of standard definition or high definition input signal on
one electrical input (two electrical inputs in the case of 8945EDA-D),
• Non-inverted outputs allow distribution of compressed signals for handling
such as DVB-ASI,
• Eight HD or SD/ASI electrical outputs,
• Provides a bypass mode for non-supported signal rates,
• Provide alarm (signal presence detection) and status management,
• Supports SNMP MIB reporting basic board alarms, and
• Remote control and monitoring support: web pages, Newton control panel,
NetConfig management system.

Product Environment
The 8945EDA and 8945EDA-D modules are installed only in a Gecko Flex frame.
They may not be installed in older 8900 frames. The devices can be located in
broadcast centers, video production facilities, OB vans and production trucks. The
main application of those products is the distribution of the incoming SD/ASI or
HD SDI signals to the video processing devices (routers, switchers, tape recorder,
monitoring devices, etc.). Usually, those devices are located in the area of the
reception transmission signal.

Installation
Local Configuration
Installation
The front and the rear modules are delivered together as a set.
Installation of the 8945EDA or 8945EDA-D module is a process of:
• Placing the rear module in a rear frame slot,
• Placing the front module in the corresponding front slot, and
• Cabling signal ports.
The 8945EDA and 8945EDA-D modules can be plugged in and removed from a
Gecko Flex frame with power on, without disrupting operation on adjacent running
modules. When power is applied to the module, LED indicators reflect the initialization process (see Power Up on page 12).
Local configuration of the 8945EDA and 8945EDA-D consists of several switches
as shown in Figure 2.

Config Mode
Switch position
The Config Mode Switch may be on Remote (1) or Local (0).
When the switch is on the 0 position, the other switches must be manually positioned.
8436-02
When the switch is on the 1 position, the other parameters are positioned by the
web page via the NetConfig application.
