Installation

Installation

Gecko 8900 Frame

The 8964ENC and 8964ENC-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.
Installation of the 8964ENC 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 8964ENC 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 8964ENC module can be installed in all Gecko 8900 video frames but with varying maximum quantities determined by frame cooling capacity.
Ta bl e 1 provides the power capacity, cooling capacity, and maximum
module count for each frame type.
Table 1. Video Frame Power Capacity
Note Module capacity figures assume no other modules are in the frame.
Using the latest 8900NET (Net card) module (version 4.3.0 or later), a link to the 8900 Frame Status web page ( 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.

8900 module slots are interchangeable within the frame. There are 10 BNC connectors in each slot’s I/O group. The functional assignment of each con nector in a group is determined by the module that is placed in that slot. The maximum number of modules a Gecko 8900 frame can accept is ten.
Figure 2 illustrates the rear connector plate for a Gecko 8900 frame.
Figure 2. Gecko 8900 Series Frame Rear Connector
To install a module in the frame:
-
1. Insert the module, connector end first, with the component side of the
module facing to the right and the ejector tab to the top.
2. Verify that the module connector seats properly against the backplane.
3. Press in the ejector tab to seat the module.

GeckoFlex Frame

Installation of the 8964ENC/FS module in a GeckoFlex frame includes:
1. Installing the 8900V-R rear module into the rear of the frame,
2. Placing the 8964ENC/FS module in the corresponding front frame slot,
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
Install the rear module first, then install the front module.
Installation
and
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.
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 screw­driver.
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 Tabl e 7 on
page 62.
8964ENC/-FS — Instruction Manual 13
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.

Operation Indicator LEDs

The front LED indicators and configuration switches are illustrated in
Figure 7. Upon power-up, the green PWR LED should light and the yellow
CONF LED should illuminate for a few seconds for the duration of module initialization.
Note When a module is first plugged into a GeckoFlex frame, the 8900NET module
(if present) may report a momentary fault. This will clear once the module has booted up.
With factory default configuration and a valid input signal connected, the green PWR LED and one of the green signal standard LEDs (525 or 625) should illuminate (refer to
Ta bl e 2 on page 19 to see the possible operating
indicator combinations).
Video input presence on each encoder channel is indicated by the CH1– CH4 green LEDs on.

Configuration Summary

The 8964ENC 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 27)
Remote Control and Monitoring (page 33)
Operation of these control types is explained in detail in their respective sections of this manual. format of all parameters and their ranges, default values, and remote, local, and control panel function names and locations for setting each value.
Ta bl e 8 on page 67 provides a summary in table
This section provides a summary of all parameters that can be configured on the 8964ENC 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 Timing and Freeze Controls
With a standard 8964ENC module with no Frame Sync the following line sync timing adjustments are available:
Horizontal Timing – adjusts the horizontal delay of the channel output in half pixels. and
Fine Phase Adjustment – adjusts the horizontal fine phase relative to the input sync reference (in percent of 37 ns).
With an 8964ENC-FS module (8964ENC with Frame Sync, see Module
Option Upgrade on page 61), the following vertical timing adjustments can
be made:
Horizontal Timing – identical to the line sync timing above.
Fine Phase Adjustment – identical to the fine phase timing above.
-
Vertical Timing – adjusts vertical delay in line increments.
20 8964ENC/-FS — Instruction Manual
Also available with the 8964ENC-FS are the following freeze controls (one must be selected from the five choices):
AutoBlue – when AutoBlue is enabled on a channel, the output will
automatically freeze to a blue screen when the input signal is lost on that channel.
AutoFreeze – when AutoFreeze is enabled on a channel, the output will
automatically freeze on the last valid field when the input signal is lost on that channel.
Field 1 – manually freeze the output signal on field 1 of the last frame.
Field 2 – manually freeze the output signal on field 2 of the last frame.
Frame – manually freeze the output signal on the last frame.
Note A field freeze provides less resolution and no motion artifacts in the output.
In frame mode, the resolution is higher since both fields are present, but the presentation of the two fields can cause motion artifacts.
Picture Enhancer Controls
Configuration
The Picture Enhancer feature is standard on the 8964ENC and 8964ENC-FS modules. This feature allows separate picture enhancement control on each channel output.
Use the following controls for bypassing or disabling picture enhancement:
Bypass – the Picture Enhancer circuitry can be bypassed to decrease the
amount of delay in the module if required.
Disable – the Picture Enhancer process can be disabled, still routing the
signal through the Picture Enhancement circuitry.
When Picture enhancement is enabled, the following controls are available:
Split screen – split the output screen to view the original video on the
left and the enhanced video on the right.
Detail level – set the amount of picture enhancement detail based on the
split screen comparison.
Overshoot protection – set the amount of clipping looking at a wave-
form monitor.

Configuration
Vertical Blanking Interval Controls
The 8964ENC provides line-by-line vertical blanking interval (VBI) pro­cessing.
Line Categories
The line categories used in the configuration of the video signal for the 8964ENC 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.
The line numbers for each category above are defined in Tab le 3 for both 525 and 625 line rates.
