About This Manual
This manual describes the features of a specific module of the 8900 Series
Modular Products family. As part of this module family, it is subject to
Safety and Regulatory Compliance described in the 8900 Series frame and
power supply documentation (see the 8900TX/8900TF/8900TFN Frames
Instruction Manual ).

8990ARC SD Aspect Ratio Converter
Introduction
The 8990ARC converts between standard (4:3) and widescreen (16:9) SD
video formats. Flexible aspect ratio control is provided on the module’s
front panel and through remote control using the 8900 web browser graphical user interface (GUI).
The 8990ARC is compact and fits in the 8900 frame which holds up to 10
modules in 2 RU. It supports 270 Mb serial digital video with outputs referenced from the input signal.
Key features include:
■
270 Mb component serial digital input and output,
■
Module is hot-swappable,
Module settings are stored in non-volatile memory,
■
■
Automatic 525/625 line selection based on video input,
■
Passes horizontal ancillary data (HANC),
Passes or blanks vertical interval ancillary data (VANC),
■
■
GPI (general purpose interface) input can recall one of four userdefined preset settings,
Optional blanking of top and bottom one, two, or three active lines, and
■
Remote control and monitoring through the 8900 frame ethernet I/F.

8990ARC SD Aspect Ratio Converter
Installation
Installation of the 8990ARC module is a process of:
Placing the module in the selected frame slot, and
■
■
Cabling and terminating signal ports.
The 8990ARC module can be plugged in and removed from an 8900 Series
frame with power on. When power is applied to the module, LED indica-
tors reflect the initialization process (see Power Up on page 5 ).
Frame Capacity
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 module count for the 8990ARC in each frame type.
Table 1. Power, Cooling, and Module Capacity of 8900 Frames
Capacity Calculated
Power (W) 60 60 100 100 100
Recommended Module Cooling (W) 30 60 30 90 90
8990ARC Modules 6 10 6 10 10
Note
Module capacity figures assume no other modules are in the frame.
If the maximum number of modules a frame can handle is less than ten,
provide as much space between the modules as possible.

Module Placement in the 8900 Frame
There are ten cell locations in the frame to accommodate either analog or
digital modules. These are the left ten locations. Refer to Figure 1.
The two cells on the right are allocated for the power supplies. For addi-
tional information concerning the Power Supply module, refer to the 8900
Power Supply manual.
The third cell from the right is allocated for the Frame Monitor or Network
Interface module. These modules provide health bus monitoring and
control options.

8900 modules are interchangeable within the module cells. There are 10
BNC connectors in each cell’s I/O group. The functional assignment of
each connector in a group is determined by the module that is placed in
that cell. The maximum number of modules an 8900 frame can accept is
ten. Figure 2 illustrates the rear connector plate for an 8900 Series frame.

Note
At the back of this manual (hard-copy only) are die-cut overlay cards that can
be placed over the rear connector BNCs to identify the specific 8990ARC connector functions.
To install a module in the frame:
Insert the module, connector end first, with the component side of the
module facing to the right and the ejector tab to the top.
Verify that the module connector seats properly against the backplane.
Press the ejector tab in to seat the module in place.

Cabling
Loop-through Input
Connect an input source to one of the loop-through input connectors, J9 or
J10 (see Figure 3). The 8990ARC input accepts SMPTE 259M 8 or 10-bit
component serial digital video. Terminate the unused connector into 75
the signal is not looped to other equipment.

General Purpose Interface (GPI) Connections
BNCs J7 and J8 accept GPI control signals that select one of four user-
defined preset settings that are stored using the onboard configuration con-
trols or the remote GUI controls. The GPI can be used with a user-provided
panel with four latching momentary switches and appropriate resistors.
No tally is provided from the module (see GPI Control on page 12 ).

Power Up
Operation Indicator LEDs
Power Up
The various front LED indicators and configuration switches are illustrated
in Figure 4. Upon 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 green signal standard LEDs (525 or 625)
should illuminate (refer to Table 2 on page 6 to see the possible operating
indicator combinations).
Video input presence is indicated by the appropriate 525 or 625 LED (indicating a 525-line or 625-line input signal has been detected). The appropriate Mode LED is on.
