GPI Control
The GPI control input at BNCs J7 or J8 (not both) on the rear panel is a
Ω
loop-through input to an A/D converter and a 1.21 K
When the module’s GPI function is enabled, the 8990ARC software will
recognize a GPI input voltage level to select one of four stored user-defined
modes. Looping the input to additional modules allows a single GPI signal
to set them all (up to 10 modules).
The GPI input is created by the application of a parallel resistor between
the coax center and common ground that results in a voltage lower than
+5 V to the A/D converter.
The following voltages (all ±0.4 V) will select the GPI register indicated:
• 1.25 V = GPI 1
• 2.08 V = GPI 2
resistor to +5 V.
• 2.92 V = GPI 3
• 3.75 V = GPI 4
The resistors required for these voltages are shown in Figure 4.

The configuration of the 8990ARC determines:
•Output aspect ratio (16:9/4:3),
•Display conversion modes: (see
• Bypass (no conversion),
• Pillarbox for 16:9 output or Letterbox for 4:3 output,
• Full Width for 16:9 output or Full Height for 4:3 output,
• 14:9 output,
•High or Low vertical resizing filtering – for vertical black/white or
severe chroma transitions,
• Position of converted outputs on the monitor (Tilt for vertical and Pan
for horizontal positioning),
• Blanking or passing of vertical ancillary data (VANC),
•Number of active video lines selected as data lines (None, 1, 2, or 3),
• Enable one of three Video Index Control modes allowing control from
data within the video input signal,
• Enable one of three Wide Screen Signaling (WSS) Control modes
allowing control from video source data and selection of WSS line (lines

saturated horizontal edges. Select
tical black/white or severe chroma transitions.
Output Conversion Modes
One of four output conversion modes for either 4:3 or 16:9 output aspect
ratio format can be selected with user controls as follows:
• For 4:3 format, 1 = Bypass, 2 = Letterbox, 3 = Full Height, 4 = 14:9, or
• For 16:9 format, 1 = Bypass, 2 = Pillarbox, 3 = Full Width, 4 = 14:9.
Examples of the conversion modes are shown in Figure 6 on page 15 and
Figure 7 on page 16 for both 4:3 and 16:9 formats.
Configuration
to remove ringing in lines with ver-
Low
Control of the desired video output conversion mode can be from four
sources:
•Web page, Newton Control Panel, or local control,
•GPI triggering of pre-programmed registers,
•Video Index Coding data on video input signal, or
•Wide Screen Signaling (WSS) on input signal.
When set for Remote/Local operation (Figure 9 on page 29), the web page,
Newton Control Panel and local control settings are always enabled and
always valid. GPI controls are based on these settings, stored in GPI registers, and triggered by the web page, local controls, or an customer-supplied
external device. Video Index Coding and WSS may or may not be valid
depending on the presence of information on the input signal. The status
of both WSS and Video Index Coding is reported at all times for the input
signal on the Settings web page in read-only form (
page 36).
Table 3 shows the output formatting control options and the resultant
output processing for various input signals and controls enabled.

Configuration
The output will change according to the last valid command from the
highest priority enabled control. For example, consider a case where the
Video Index is enabled and its input is invalid. The user sets the conversion
mode with the control panel to Bypass which passes the Video Index signal
through to the output. The Video Index input changes to valid and sets the
conversion mode to Letterbox. The Video Index then becomes invalid
again.
The output will remain at Letterbox until another valid enabled control
changes the conversion mode. It will not revert back to the setting set with
the control panel.
Tilt/Pan Control
Tilt and pan controls for left and right, centering, and top and bottom positioning are provided depending on the Conversion mode selected.
Video and VBI Line Handling
The module handles lines in the video input differently depending on
whether the line is an active video or a vertical interval line.
Vertical interval lines (lines 1-20/264-283 in 525 or lines 624-23/311-336 in
625) are either passed to the output unchanged or blanked by the VBI
Bypass circuit. This selection is made with the VANC Data control.
Active video lines (lines 21-263/284-525 in 525 or lines 24-310/337-623 in
625) are processed through a scaling circuit. Depending on the mode of the
module and the line number, they are either passed to the output, replaced
with a scaled version of part of the input active video, or replaced with
black fill.
If, for example, the scaling circuit is magnifying the video vertically, all
active lines are replaced with scaled lines and the portion of the scaled
video that doesn’t fit in to the active space is discarded.
If the scaling circuit is reducing the video vertically, all of the scaled video
is displayed on the output and active lines that are not covered by the
scaled video are blanked.
When information such as closed captioning data is present on one of the
first three active video lines, (lines 21/284, 22/285, and 23/286 in 525 or
lines 24/337, 25/338, and 26/339 in 625), these lines can be designated as
data lines and will be treated as part of the vertical interval passing the data
to the output when the VANC Data control is set to
Pass
.
18 8990ARC Instruction Manual
Configuration
This is done using the Data Lines control as follows:
•When the Data Lines control is set to 1, the first active line of video is
treated as part of the vertical interval and passed to the output through
the VBI Bypass circuit maintaining any data it contains.
In the active video scaling circuit, this first active video line is blanked
before the active video is processed in the scaling circuit so that no
non-video information will appear on the video output. The last active
video line is also blanked to maintain symmetry on the video output.
•When the Data lines control is set to 2, the first 2 active lines of video
are treated as part of the vertical interval in the VBI Bypass circuit.
These first 2 lines of active video are blanked before the active video is
processed in the scaling circuit. The last two lines of active video are
also blanked before the scaling circuit to maintain symmetry on the
video output.
•When set to 3, the first three lines of active video are treated as vertical
interval lines in the VBI Bypass circuit. These first 3 lines of active video
are blanked before the active video is processed in the scaling circuit.
The last three lines of active video are also blanked before the scaling
circuit to maintain symmetry on the video output.
For the exact line number of the lines that are blanked with the different
Data Lines control settings for 525 and 625 line rates, refer to the parameter
for
Active lines blanked before processing by scaling circuit
Specifications section.

Video Index Coding
In Video Index Coding, video source data can be inserted in the video input
signal on lines 11 and 324 for 625, on lines 14 and 277 for 525, to identify the
signal line standard and aspect ratio. If this information is present and the
8990ARC Video Index Control function is enabled in one of three Video
Index Coding modes and the module output mode matches the input, the
module will pass the signal as is. If the output mode does not match, the
module will use the selected conversion mode (see
Modes
on page 17). The Video Index coding is passed through to the
Output Conversion
8990ARC output unaltered.
This module supports three modes of Video Index Coding: Standard, Modified, and Custom.
Standard Video Index Coding
Support for Standard Video Index Coding is based on the SMPTE RP-186
standard. In Standard mode, the three least significant bits (b0, b1, and b2)
of the first byte (octet) contain the aspect ratio information of the video.
Refer to Table 4 for the definition and how this information is interpreted
by the module. Note that the module ignores the line rate.

Modified Video Index Coding
In the Modified Video Index Coding (a revision of SMPTE RP-186 based on
the ARDSPCI rev 1), the definition of the first byte (octet) of the Video Index
data has been modified to hold additional information. The three least significant bits of this byte have not changed; they still contain the aspect ratio
information of the video. Refer to Table 5 for the definition of the first byte
and how it is interpreted by the module. Note that the line rate is ignored
by the module.

Wide Screen Signaling (WSS)
Wide Screen Signaling (WSS) for 625 systems is also supported on this
module. One of three WSS control modes can be selected: Standard, Modified, and Custom.
If WSS is enabled, the 8990ARC output conversion mode will be controlled
according to this input data. If Video Index Control is also enabled, the WSS
control, when present, will take precedence as explained in Table 3 on
page 17. WSS coding is passed through to the 8990ARC output unaltered.
WSS Line Selection
According to the industry standard WSS protocol, in 625-line systems the
video input signal can contain video source data on line 23. This module
has been modified to allow the line containing source data to be selected as
any line from 13-27. The module will only search for WSS data on the line
selected by the WSS control on the web page, control panel, or local control.
Standard Wide Screen Signaling
Support for standard WSS mode is based on the EN 300 294 V1.3.2
(1998-04) standard. Table 7 shows the setting for the module based on the
output mode selected and the contents of the Group 1 data in the WSS
signal.

Modified Wide Screen Signaling
Support for the Modified WSS is based on a modified version of the Standard WSS described in Standard Wide Screen Signaling on page 24. The
changes (described in the L23 specification) redefine the Group 1 bits to
match the AID bits of the Modified Video Index Coding specification. The
Group 2 bits have been redefined to match the ARD of the Modified Video
Index Coding. Both of these (AID/ARD) are described in Modified Video
Index Coding on page 21.
The operation of the module when the WSS control is enabled is the same
as when the Video Index Coding is enabled except the control information
is taken from a different part of the video and it is formatted differently.
Custom Wide Screen Signaling
Custom Wide Screen Signaling allows selection of the conversion mode
and tilt desired for each of the eight states of the least three significant bits
of the first octet with the web page controls. When the Custom mode is
selected, the LSB (Least Significant Bit) can be selected along with the
desired output mode.
Configuration
For WSS the output selections are the same as those listed for the Video
Index Coding on page 23.
GPI Control
GPI control of four GPI registers can be enabled or disabled. Each register
can be saved and recalled with local or remote controls. Once a register is
saved, it can also be recalled with a GPI trigger from an external device. See
General Purpose Interface (GPI) Connections on page 10.

Onboard Configuration Switches and LEDs
The 8990ARC module can be configured using the on-board rotary and
paddle switches shown in Figure 9. The CONF LED is a configuration
status indicator.
These three components perform the following:
• Function (rotary) switch — Addresses one of 16 possible positions (0
through 9 and A through F) to access a desired function for configuration. Not all positions are used (see Table 9 on page 30).
Note The Function switch should be kept 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.
• CONF (configuring) LED — When on, indicates the module is initializing or processing configuration information.

Remote Configuration and Monitoring
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 9 on page 29).
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.
Configuration
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
module are listed in Table 8 on page 26.
An example of the Newton Configurator is shown in Figure 10 on page 32.

Use of the web interface offers the following considerations:
•Provides complete access to all module status and configuration functions, including naming of input, factory parameter and default recalls,
slot configuration, and SNMP monitoring controls.
•Web access will require some normal network time delays for processing 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 and reporting status for SNMP and 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)
Status Monitoring
including configuration errors (warning), internal faults, and normal
operation (Pass).
• 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
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.
8990ARC Instruction Manual 43
Status Monitoring
Frame Alarm
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 Table 2 on page 13. 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 the 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 page – reports overall frame and module status in graphical and text formats.
•Module Status 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 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.
•Grey = 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. Most module status reporting items
can be enabled or disabled on individual configuration web pages.
44 8990ARC Instruction Manual
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 page for the Frame, the
8900NET module, and each module slot. Refer to the 8900NET Network
Interface Instruction Manual for installation instructions.

Service
The 8990ARC Digital to Analog Converter 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 otherwise directed 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 (see Figure 20) and check Fuse F1
if no voltage is detected.
•Check for presence and quality of input signals.
•Verify that source equipment is operating correctly.
•Check cable connections.
•Check output connections for correct I/O mapping (correct input connector is used for the corresponding channel output).
Refer to Figure 5 on page 12 for the location of PWR LED and Table 2 on
page 13 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 Contacting Grass Valley at the front of this document for the Grass
Valley Customer Service Information number.

Input and Ancillary Data Processing
The input signal is deserialized and enters the control Field Programmable
Gate Array (FPGA). Sync is detected and is used to H-lock the system 27
MHz clock. All horizontal and vertical interval data is routed through the
ancillary date (ANC) bypass FIFO to delay match the re-sized active
picture data and is multiplexed back, with the re-sized data, to the parallel
data output. This output is serialized and output through 4 buffers and
connectors.

Active Picture Processing
The active picture portion is routed through the H and/or V re-sizing
portion shown. Depending on the mode and input format selected, H and
V will be scaled up or down. The maximum delay for this processing is
50 8990ARC Instruction Manual
required for vertical magnification, where the starting position of the
output will be at last 3/4 position in the input picture. The worst case is 4:3
input and mode 3 (full-width) with the vertical position set at the bottom
of the field. In all modes, the overall delay will be fixed at this worst case
for each line rate.
H & V Re-sizing Algorithm
Scaling up (magnify) creates more pixels or lines in a selected region than
is available in the input and therefore requires a horizontal or vertical position adjustment. It is accomplished by periodically holding off the reading
of data from the input FIFO, while re-computing a new pixel/line in its corresponding poly-phase filter.
Scaling down (shrink) decimates pixels or lines from the entire source
image and results in a blanked region in the output, which is adjusted
using the horizontal or vertical position adjustment. It is accomplished by
periodically holding off the writing of data to the output FIFO, while
re-computing a new pixel/line in its corresponding poly-phase filter.
Functional Description
In modes 2 and 3 only one operation is performed, H or V scale up or down.
In mode 4, the 14:9 sub-image both scaling up and scaling down are done
independently and simultaneously.
Vertical Resize Filtering
All the poly-phase filters used for vertical magnification or shrink have
maximum bandwidth. Video sources with high contrast or chroma saturated horizontal edges will produce some filter ringing within a few lines
above and below the edge. One example of such an edge is contained in the
SMPTE color bar test pattern. If this effect needs to be eliminated, then
linear-interpolators can be used in these vertical processing modes in the V
Process BW configuration selection. The consequence of this selection is
having a reduced vertical bandwidth.
Video Index Information Coding Support
Video source data can be inserted on lines 11 and 324 in 625 line rate or lines
14 and 277 in 525 line rate systems per SMPTE RP-186 specification. The
very first section of this coding region, Class 1.1, data octet 1, encodes
options on the source of being 525/625 line and 4x3 or 16x9 format. If the
input to the 8990ARC contains this section of coding and the Video Index
Control function is enabled, the mode will automatically change to 1 (no
processing) if the input format and selected output format are the same. It
will revert to the previous, 2 through 4 selection when either the input
format changes or the user changes the desired output format.
