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.

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.

Onboard Module Configuration Switches and LEDs

The 8950ADC module can be configured locally using the rotary and
paddle switches shown in Figure 5 on page 18. The CONF and 2ND func­tion LEDs are configuration status indicators. These four components
perform the following:

• Function (rotary) switch — This switch is used to access a desired func­tion for configuration. The switch addresses two banks of functions;
each bank has 16 possible positions (0 through 9 and A through F). Not
all positions are used (see Table 5 on page 19). The alternate bank of
functions is accessed each time the Function Switch makes a complete
revolution past zero: While in Bank 1, a complete revolution past zero
accesses Bank 2; while in Bank 2, a complete revolution past zero
accesses Bank 1. The 2ND LED indicates which bank is currently being
accessed.

CONF – configuration LED

JP2

REMOTE

Note

The Function switch should be kept in the position for the selected mode (1
through 7) or in position 0 when not in use to avoid any inadvertent change
in configuration. 0 is an inactive position.

•SW2 (paddle) switch — Actuates or selects the desired setting for the
selected function when the switch is held momentarily in either the up
or down position.

•2ND LED — When on, indicates that user is accessing the second bank
of configuration parameters.

• CONF (configuring) LED — When on, indicates the module is initial­izing or processing configuration information.

Remote Configuration and Monitoring

8950ADC configuration and monitoring can be performed using a web
browser GUI interface or a networked Newton Control Panel when the
8900NET Network Interface module is present in the video frame (Gecko
8900TFN-V frame). Each of these interfaces is described below.

Note For remote access, make sure the jumper block on the module is set for both

Local and Remote access (Figure 5 on page 18).

8900NET Module Information

Refer to the 8900NET Network Interface Module Instruction Manual for
information on the 8900NET Network Interface module and setting up and
operating the Gecko 8900 frame network.

Note The 8900NET module in the frame must be running software version 3.2.0 or

higher for proper remote and control panel operation. Upgrade software and
instructions for the 8900NET can be downloaded from the Grass Valley web
site.

Newton Control Panel Configuration

A Newton Control Panel (hard or soft version) can be interfaced to the
Gecko 8900 Series frame over the local network. Refer to the documenta­tion that accompanies the Newton Modular Control System for installa­tion, configuration, and operation information.

Control panel access offers the following considerations for module config­uration and monitoring:

•Ability to separate system level tasks from operation ones, minimizing
the potential for on-air mistakes.

•Ability to group modular products—regardless of their physical loca­tions—into logical groups (channels) that you can easily manipulate
with user-configured knobs.

•Update software for applicable modules and assign frame and panel IP
addresses with the NetConfig Networking application.

•Recommended for real-time control of module configuration parame­ters, providing the fastest response time.

Note Not all module functions are available with the control panel, such as E-MEM

and factory default recalls. The available control panel controls for the
8950ADC module are listed in Table 4 on page 16.

An example of the Newton Configurator is shown in Figure 6 on page 21.

Configuration

Web Browser Interface

The web browser interface provides a graphical representation of module
configuration and monitoring.

Use of the web interface offers the following considerations:

•Provides complete access to all module status and configuration func-

tions, including naming of inputs and outputs, factory parameter and
name default recalls, E-MEM functions, slot configuration, and SNMP
monitoring controls.

•Web access will require some normal network time delays for pro-

cessing of information.

•Configuration parameter changes may require pressing

Enter, upload processing time, and a manual screen refresh to become

effective.

•Web interface recommended for setting up module signal and slot

names, E-MEMS, and reporting status for SNMP and monitoring.

Refer to the Frame Status page shown in Figure 7 on page 22. The 8900
modules can be addressed by clicking either on a specific module icon in
the frame status display or on a module name or slot number in the link list
on the left.

Service

The 8950ADC modules make extensive use of surface-mount technology
and programmed parts to achieve compact size and adherence to
demanding technical specifications. Circuit modules should not be ser­viced in the field unless directed otherwise by Customer Service.

If your module is not operating correctly, proceed as follows:

•Check frame and module power and signal present LEDs.

•Verify power at the voltage testpoints (Figure 17) and check Fuse F2 (on
the back of the module circuit board) if no voltage is detected.

•Check for presence and quality of input signals.

•Verify that source equipment is operating correctly.

•Check cable connections.

Refer to Figure 4 for the location of PWR LED and Table 2 on page 12 for
proper LED indications.

If the module is still not operating correctly, replace it with a known good
spare and return the faulty module to a designated Grass Valley repair
depot. Call your Grass Valley representative for depot location.

Refer to the Contacting Grass Valley at the front of this document for the

Status Monitoring

Status Monitoring

This section provides a summary of status monitoring and reporting for a
Gecko 8900 Series system. It also summarizes what status items are
reported and how to enable/disable reporting of each item. There are a
number of ways to monitor status of modules, power supplies, fans and
other status items depending on the method of monitoring being used.

8900 Frame status will report the following items:

• Power supply health,

• Status of fans in the frame front cover,

•Temperature,

•Module health, and

• Frame bus status.

Module health status will report the following items:

• Internal module state (and state of submodule or options enabled)
including configuration errors (warning), internal faults, and normal
operation (Pass).

LEDs

• Signal input states including valid/present (pass), not present or
invalid (warning), not monitored, and not available (no signal inputs).

•Reference input states including locked/valid (pass), not
locked/invalid (warning), and not monitored.

• Signal output states with reporting functionality (reference output).

LEDs on modules in the frame and on the front of the 8900TF/TFN frames
indicate status of the frame and the installed power supplies, fans in the
front covers, and modules. (The 8900TX-V/A frames have no LED indica­tors on the front cover.)

When a red FAULT LED is lit on a frame front cover, the fault will also be
reported on the 8900NET or Frame Monitor module. The LEDs on the front
of these modules can then be read to determine the following fault condi­tions:

• Power Supply 1 and 2 health,

• Fan rotation status,

• Frame over-temperature condition,

• Frame Bus fault (8900NET only), and

•Module health bus.

36 8950ADC Instruction Manual

Frame Alarm

Status Monitoring

In general, LED colors used on the frame and modules indicate:

•Green – normal operation, (Pass) or signal present, module locked.

•Red – On continuously = fault condition, flashing = configuration error.

•Yellow – On continuously = active condition (configuration mode or

communication), flashing in sequence = module locator function.

Status LEDs for this module are described in Operation Indicator LEDs on

page 11. LEDs for the 8900NET module are described in the 8900NET

Network Interface Instruction Manual.

A Frame Alarm connection is available on pins 8 and 9 of the RS-232 con­nector on the rear of 8900 frame (Frame Monitor or 8900NET Network
Interface module required). This will report any of the status items enabled
with the 8900NET or Frame Monitor module configuration DIP switch.
Connection and use of the Frame Alarm is covered in detail in the 8900NET
Network Interface Instruction Manual.

Web Browser Interface

When the 8900NET module is installed in the frame, a web browser GUI
can indicate frame and module status on the following web pages:

• Frame Status web page – reports overall frame and module status in

graphical and text formats.

•Module Status web page – shows specific input and reference signal

status to the module along with enabled options and module versions.

•A Status LED icon on each web page to report communication status

for the frame slot and acts as a link to the Status web page where warn­ings and faults are displayed (8900NET version 3.0 or later).

In general, graphics and text colors used indicate the following:

•Green = Pass – signal or reference present, no problems detected.

•Red = Fault – fault condition.

•Yellow = Warning – signal is absent, has errors, or is mis-configured.

•Gray = Not monitored (older 8900 module).

•White = Not present.

Status reporting for the frame is enabled or disabled with the configuration
DIP switches on the 8900NET module. Some module status reporting items
can also be enabled or disabled on individual configuration web pages.

8950ADC Instruction Manual 37

Status Monitoring

SNMP Reporting

The Gecko 8900 Series system uses the Simple Network Monitoring Pro­tocol (SNMP) internet standard for reporting status information to remote
monitoring stations. When SNMP Agent software is installed on the
8900NET module, enabled status reports are sent to an SNMP Manager
such as the Grass Valley’s NetCentral application.

There are both hardware and software report enable switches for each
report. Both must be enabled for the report to be sent. Software report
switches are set on the 8900NET Configuration web page for the Frame, the
8900NET module, and each module slot. Refer to the 8900NET Network
Interface Instruction Manual for installation instructions.

Functional Description

Input Buffers/Amplifiers/Low Pass Filters

Analog to Digital Converters

Digital Signal Processor FPGA

Three-channel input Clamping Video Amplifiers support the professional
studio TV standard with 20 MHz bandwidth and > 60dB signal to noise
ratio. Black level voltage is under CPU control (DC feedback D/A con­verters). Signals are passed from the amplifiers to three identical Low Pass
Filters (LPF), where all spectral components above 15 MHz are removed
from incoming signals.

The three 10-bit ADCs have a 54 MHz sampling rate, and perform high
speed analog to digital conversion on the signals received from the LPFs.

The DSP FPGA performs the following signal processing:

• Input Signal Processor
After analog to digital conversion, the digitized video signal passes

through the Digital Input Signal Processor. This controls the gain of all
three input signals individually in the range of ± 15%. User input gain
control is also available through Embedded Processor. The clipping
circuit preludes overshooting errors in cases where either the input
signal level or amplifier gain is too high.

•Color Space Converter
The 8950ADC supports Y, (B-Y), (R-Y) or GBR input, and the Color

Space Converter automatically connects to the appropriate signal path.
The Color Space Converter converts an incoming GBR signal to Y,
(B-Y), (R-Y) according to the D1 Color space matrix.

• Sync Processor
The Sync Processor contains the H&V Extractor, Frame Pulse Extractor,

Standard Detector, and PLL Phase Detector Input Signal. (The Analog
Sync Separator and PLL Phase Detector are not part of the FPGA.)

• Filters and Decimators
The DSP FPGA performs Low Pass filtering (6 MHz bandwidth) and

decimation by 4 for all three channels. For the B-Y and R-Y channels the
DSP FPGA performs additional Low Pass filtering and decimation by 2
(3 MHz bandwidth).

•Control
The Control FPGA contains parallel communication blocks between

the embedded processor and FPGA.

40 8950ADC Instruction Manual

Functional Description

Input Phase Lock Loop (PLL) and 54 MHz clock generator

From the incoming composite sync, the PLL generates a 54 MHz clock for
oversampling. This clock also servers as a free-running clock when no
input signal is present.

Delay line

The on board delay line provides a maximum 2.5 line signal delay. The
delay time is under user control in 37 ns increments.

Serializer

The Serializer is a standard D1, 10-bit, 270 MHz serializer with embedded
Error Data Handling.

Embedded processor

The embedded processor provides the interface between the user and all
the processing logic of the 8950ADC, as well as communication between
the 8950ADC and a remote host processor.
