Installation
The 8964DEC and 8964DEC-FS module can be installed in either an 8900
Gecko or a GeckoFlex frame. An 8900V-R rear module is required for use in
the GeckoFlex frame.
Gecko 8900 Frame
Installation of the 8964DEC module in a Gecko 8900 frame is a process of:
1. Placing the module in the proper frame slot, and
2. Cabling and terminating signal ports.
The 8964DEC module can be plugged in and removed from a Gecko 8900
video frame with power on. When power is applied to the module, LED
indicators reflect the initialization process (see Power Up on page 18).
Frame Capacity
The 8964DEC module can be installed in all Gecko 8900 video frames but
with varying maximum quantities determined by frame cooling capacity.
Table 1 provides the power capacity, cooling capacity, and maximum
module count for each frame type.
Note Module capacity figures assume no other modules are in the frame.
X = Not recommended without forced air cooling.
Using the latest 8900NET (Net Card) module (version 4.3.0 or later), a link
to the 8900 Frame Status web page (Figure 11 on page 34) then select the
link to the Power Supply/Demand web page for determining the power
capacity for the frame. Using this function, the 8900NET module will deter-
mine how much power is being consumed and report back when power
has been exceeded.

8964DEC/-FS — Instruction Manual 13
Installation
GeckoFlex Frame
Installation of the 8964DEC/FS module in a GeckoFlex frame includes:
1. Installing the 8900V-R rear module into the rear of the frame,
2. Placing the 8964DEC/FS module in the corresponding front frame slot,
and
3. Cabling and terminating signal ports.
Module Installation Precautions
Please read and follow the precautions listed below before installing the
front and rear modules:
• Use standard anti-static procedures during installation. As modules
can be installed or removed when the GeckoFlex frame is powered up,
before removing the cover, please use an anti-static bracelet or heel
strap tied to a metal part of the frame.
• Install the rear module first, then install the front module.
• When installing or removing a rear module, loosen or tighten the
screws holding the retainer clips to the frame manually with the
retainer clip tool provided inside the front cover of the frame or use a
2 mm (5/64”) hex screwdriver. Please do not use an electric screw-
driver.
Note On newer 751- version GeckoFlex frames, a Rear Retainer Clip removal tool
and 2 extra retainer clips and screws for installing them are provided on the
inside of the frame cover.
• Make every effort to leave the screws holding the retainer clips in place
(do not remove them completely). They are very small and can easily
drop into other equipment causing a shorting hazard. (Two turns of the
screw should be enough to loosen the screws, 3 turns or more will
remove it.)
• When installing a rear module, tighten the screws on the retainer clips
just until snug. Do not apply more force than is necessary to seat the
rear module. Do not use an electric screwdriver. Refer to the rear
retainer screw torque specification in the Mechanical section of Table 7 on
page 61.

14 8964DEC/-FS — Instruction Manual
Installation
Rear Module Installation
All unused rear slots in a GeckoFlex frame should have a blank rear
adapter cover installed.
1. Each 8900V-R rear module or blank rear adapter cover is held in place
by two retainer clips as shown in Figure 3. Loosen (but do not remove
completely) the two screws holding each retainer clip to the frame with
a 2 mm (5/64”) hex screwdriver or the Rear Retainer Clip tool provided
(751- frames only). Pull up on the retainer to remove it, leaving the
screws in place.
CAUTION Be careful to leave the screws in place as they can be easily lost or fall into
equipment below the frame creating a shorting hazard.
2. Remove the blank rear adapter cover by inserting needlenose pliers
into the slots in the top and bottom of the blank and pulling it off.
Note To remove a rear module already installed, follow the same steps. It is helpful
to first remove the front module so the rear can be pulled out more easily.
3. Insert the rear module into the empty slot.
4. Replace each retainer clip over the two screws on both sides of the
module and push down to seat the retainer.
5. Tighten the screws for each retainer clip just until they are snug. Do not
force or torque the screws too tightly.

Configuration
Configuration
The 8964DEC can be configured locally using onboard switches or
remotely using the 8900NET network interface GUI or a networked control
panel.
Refer to the following sections for configuration instructions:
• Configuration Summary (page 20)
• Local Onboard Module Configuration (page 26)
• Remote Control and Monitoring (page 32)
Operation of these control types is explained in detail in their respective
sections of this manual. Table 8 on page 67 provides a summary in table
format of all parameters and their ranges, default values, and remote, local,
and control panel function names and locations for setting each value.
Configuration Summary
This section provides a summary of all parameters that can be configured
on the 8964DEC module. The video processing configuration is described
by what line types will be affected by the adjustments or choices made. Use
this section in conjunction with the specific configuration method instruc-
tions for each configuration type.
Video Processing Controls
The 8964DEC provides video processing controls for the decoding process
for all four channels independently. How the video data is processed
depends on what line the video is on. Some processing affects all lines,
other processing affects just the active picture lines, programmable VBI
lines or the fixed VBI lines.
Line Categories
The line categories used in the configuration of the video signal for the
8964DEC are defined as follows:
• F_Active Lines – the portion of the active video that is fixed and always
treated by the module as carrying active video (not programmable).
• P_Active Lines – lines in the active video that can be configured by the
user to carry either active video or be reserved for carrying user data.
• CVBI – the lines in the vertical interval that can be configured by the
user.
• FVBI – the line in the vertical blanking interval that are fixed and are not
configurable.
