Section 1 Gecko 8900 Series Frames Introduction The Grass Valley Gecko™ 8900 Signal Processing System is a family of conversion, distribution, timing, and processing modules which provides support for a wide variety of signal processing applications.
Section 1 — Gecko 8900 Series Frames The power usage of 8900 modules varies greatly from less complex analog to higher complexity digital modules. To handle these power requirements and offer more control and monitoring flexibility, both frame types are offered in 8900TX, TF, and TFN models.
8900TX Convection System 8900TX Convection System The convection system consists of the following: • 8900TX-V/TX-A, convection frame, and one power supply • 8900PSX, redundant power supply (optional) The convection frame has a vented front cover and filter for convective air flow. This frame is used primarily for analog and a limited quantity of digital modules with a total power requirement less than 30 watts. Refer to Frame Cooling on page 21. The convection frame is illustrated in Figure 1.
Section 1 — Gecko 8900 Series Frames 8900TF Forced-air System The forced-air system (Figure 2) consists of the following: • 8900TF-V/TF-A, forced-air frame, Frame Monitor module, and one power supply • 8900PSX, 100 W redundant power supply (optional) The forced-air system has a front cover that is equipped with three fans for air circulation. The fan speed varies with the ambient frame temperature to extend fan life and reduce noise when the frame is used in cooler configurations and environments.
Frame Connections Frame Connections Two types of connector backplanes are available in the Gecko 8900 Series frames. The 8900 BNC/Video frame provides ten module slots, each with a loop-through input and up to eight connectors for input/output functions as needed for a specific module type (Figure 3). Figure 3.
Section 1 — Gecko 8900 Series Frames The power/communication backplane section of the frame (Figure 5 and Figure 6) provides: • AC power plug connections • DB-9 connector labeled RS-232 (requires the 8900NET module) with Frame Alarm connections (pins 8 and 9 of RS-232 connector) • Ethernet RJ-45 connector (requires the 8900NET module) The RS-232 port provides connection to a PC used for initial network configuration. Pins 8 and 9 of the RS-232 port can be used for Frame Alarm reporting.
Frame Cooling Network Configuration Storage Both the 8900 BNC/Video and Balanced Audio frames are equipped with IP address storage capability on the rear backplane. When an 8900NET module is installed (with version 3.0 software or later), the IP address assignments made on the 8900NET module for network configuration are stored on the frame. The current network configuration information will then stay with the frame if the 8900NET module is moved.
Section 1 — Gecko 8900 Series Frames Calculating Frame Power To calculate the power required for your frame, you must total all the power dissipated for each individual module. Table 3 provides the power dissipation for many of the modules compatible with the 8900 Video and Audio frames. For newer modules not listed, refer to the Specifications table in the specific module instruction manual. Table 3.
Frame Monitor and Network Interface Modules The total frame power required is less than 30 watts; therefore, the convection frame may be used. Table 5.

These are the ten cells located on the left side of the frame. Refer to Figure 8. Modules can be configured for up to eight outputs. The 8500 modules have six outputs. The 8800 and 8900 modules have eight outputs. Refer to individual module manuals for input/output configuration information.
Rear Connectors Rear Connectors Modules may be configured for a variety of inputs and outputs. The 8500 modules have six outputs. The 8800 and 8900 modules have up to eight outputs. Refer to individual module manuals for specific configuration information. Note Connector configuration overlays are available for many 8900 modules that do not use the standard DA configuration (one looping input and eight BNC outputs). These overlays are found at the back of the module Instruction Manual.
Section 2 — Installation Loop-through Input Connectors Input signals are routed through the rear of the frame. There is one loopthrough input for each module cell refer to Figure 9 and Figure 10 on page 27. Note No more than five digital modules should be looped. Use cables less than two meters in length, and an input cable of less than 200 meters of Belden 8281 (or equivalent). If not used for looping, the unused loop-through connector must be externally terminated.
