Installation

Installation

Frame Capacity

Installation of the 8950ADC module is a simple process of:

• Placing the module in the proper Gecko video frame slot, and

•Cabling and terminating signal ports.

The 8950ADC module can be plugged in and removed from a Gecko 8900
Series video frame with power on. When power is applied to the module,
LED indicators reflect the initialization process (see

Connectors

The maximum number of 8900 modules allowed in a frame is determined
by frame cooling capacity. Table 1 provides the power capacity, cooling
capacity, and maximum 8950ADC module count for each frame type.

on page 10).

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 con­nector 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.

Installation

Cabling

Note

At the back of every hard copy manual are die-cut overlay cards that can be
placed over the rear BNCs to identify specific 8950ADC connector functions.

Analog Video Inputs

Connect analog component video inputs to input connectors J3, J5 and J7
(see Figure 3). The 8950ADC accepts Y, (B-Y), (R-Y) or GBR analog input,
with or without sync on the Y/G channel. For specific input signal types,
refer the Analog Inputs listed in the Specifications on page 33.

Loop-through External Sync Input

The External Sync Input is used to provide external sync for Y/G channel
inputs that do not have a sync component. There are horizontal and vertical
phase timing requirements for the Y/G and Sync input signals (see Using

External Sync on page 14 for timing considerations).

Connect a sync input source to one of the loop-through input connectors,
J9 or J10 (see Figure 3). The 8950ADC External Sync input accepts color
black or composite sync reference signal input. Terminate the unused con­nector into 75

Ω if the signal is not looped to other equipment.

Operation Indicator LEDs

Power Up

The front LED indicators and configuration switches are illustrated in

Figure 4. On power-up the green PWR LED should light and the yellow

CONF LED should illuminate for the duration of module initialization.

With factory default configuration and a valid input signal connected, the
green PWR LED, and one of the yellow signal standard LEDs (525 or 625)
should illuminate (refer to Table 2 on page 12 to see the possible operating
indicator combinations).

Video input presence is indicated by an illuminated VID PRES LED and the
appropriate 525 or 625 LED. The 525 or 625 LED will illuminate to indicate
detection of a 525-line or 625-line input signal. The VID PRES LED indi­cates the presence of valid composite sync on the Y/G channel or reference
input.

12 8950ADC Instruction Manual

Configuration

The 8950ADC 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 13)

• Local Onboard Module Configuration (page 18)

•Remote Control and Monitoring (page 20)

Operation of these control types is explained in detail in their respective
sections of this manual.

Configuration

Configuration Summary

This section provides a summary of all parameters that can be configured
on the 8950ADC module. Table 4 on page 16 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.

Format Selections

The 8950ADC converts any one of the following analog Color Difference or
GBR video signals to a SMPTE 259M (270 Mb/s) D1 serial component
digital signal:

•SMPTE

•GBR

• Beta (US/525)

• Beta (Japan/525)

•MII (US/525)

•MII (Japan/525)

• EBU N10 (625)

Once a format is selected, the default values for that format will be loaded
to the module. The overall factory default for the module is GBR.

8950ADC Instruction Manual 13

Configuration

Level Adjustments

The factory (default) settings for signal processing functions are set to pass
a calibrated broadcast quality signal at optimum levels. Signal video and
black output adjustments are available to correct deficiencies in the input
signal.

Once any video or black adjustments are made, it is recommended to save
these settings on the User Settings web page (

page 29). If the format is reselected from the pulldown, the Level values

will return to the factory defaults for that format.

Timing/Blanking Adjustments

The following adjustments can be made to the signal that affect timing and
blanking:

•Horizontal delay – adjust the amount of horizontal delay in ns,

User Settings Web Page

on

•SAV /EAV positions – set the position of SAV/EAV (start active
video/end active video),

• Sync source – set the sync source of the module as Y/G Channel or
External, refer to

•Vertical blanking – set vertical blanking to Short (525 and 625 = 9 lines)
or Wide (525 = 19 lines, 625 = 25 lines).

Using External Sync

below, and

Using External Sync

The External Sync source is intended to provide sync when the Y/G com­ponent signal does not contain sync. The module is not intended to provide
auto-timing or frame sync functions. Allowable horizontal and vertical
phase differences between the Y/G signal and the external sync signal vary
depending upon the presence of sync in the Y/G signal. Table 3 provides
the phase difference tolerances. Exceeding these tolerances can produce an
incorrect output signal.

Within the tolerances shown, phase adjustment can be made using the
SAV/EAV (start active video/end active video) and output video delay
line adjustment settings described in

on page 19. Function F5, 2nd bank, adjusts output horizontal phase by

setting the position of active video in the digital output within a ± 400 ns
window. Function F4, 2nd bank provides output line delay of up to 2.5 lines
in 37 ns increments.
