5280-1

Model 5280 Video DAC

MODULE OVERVIEW

The 5280 module converts serial digital component video into composite analog video. Six separate composite or two Y/C (S-video) analog video outputs are available. The following analog formats are supported:

• NTSC Composite with or without setup

• PAL Composite

A serial output BNC is provided for applications requiring the serial digital input signal to loop-through to another device.

Output timing can be adjusted relative to a reference input signal by installing the 5210

Genlock Option, a submodule that plugs onto the 5280 circuit board. Incorporating a fullframe synchronizer, the 5210 also allows the 5280 to accept serial inputs that are asynchronous to the reference.

As shown in the block diagram on the following page, the serial digital input signal first passes through serial receiver circuitry then on to EDH processing and deserializing. The serial output signal goes to a cable driver and is then AC coupled to a loop-through output

BNC on the backplane. This input signal can now be looped to another device.

The deserialized video output enters genlock timing circuitry if the optional 5210 is installed. The 5210 Genlock submodule provides fully adjustable output timing for the analog outputs from the 5280 module with respect to a reference input. The reference input can be from one of three sources: the digital input to the module, the external reference input BNC specific to that module slot, or the master reference input (a loop through BNC pair on the rear of the chassis which feeds reference to all ten modules through a buffer amplifier located on the System Control module). In the second and third cases the reference source would be a composite video signal, typically color black.

When using the 5210 submodule option, the System Control module is recommended.

With the System Control module installed in the frame, Touch Screen and Avenue PC can be used to adjust module parameters such as output timing. Without the System Control module, the output video is in time with the external reference video feeding the module.

Fine timing adjustments can be accessed by remote control using one of the Avenue remote applications. Local control of the 5280 module sets the timing of the analog outputs to be aligned with the selected input reference and is fixed.

The 5210 submodule interfaces to the circuit board of the 5280 through two 40-pin headers. Power comes from the main module + 5 and ± 8 volt regulators. Timing delay on the submodule is provided by memory ICs which are controlled by circuitry which generates timing locked to the reference input of the 5200 module (either internal or external).

The deserialized video is encoded then converted to analog before entering the analog clamp and output circuitry. The video output format desired can be chosen locally by setting the front panel switches or remotely by the Avenue applications as explained in the Front Panel Controls and Indicators section of this data pack.

5280-2

Model 5280 Video DAC

The on-board CPU can monitor and report module ID information (slot location, software version and board revision), equalization (cable length), receiver status (lock and TRS errors), power status (+5 volts or ±8 volts), ancillary data status (presence of EDH flags and CRC, frequency of errors, audio and other data) to the optional frame System Control module. This information can be accessed by the user or set to register an alarm if desired using the remote control options available.

Every function and parameter on the module can be controlled from an Avenue Touch

Screen Control Panel, or the Avenue PC Control Application. Memory registers can be used to save the complete configuration of the module, making it easy to change instantly between different configurations.

APPLICATIONS

Composite Encoder for Transmission

The 5280 can convert the output of a digital master control switcher to composite video to feed a transmitter as shown in the block diagram below. The other five composite outputs can be fed to other destinations such as a composite monitor or any other standard composite device.

Serial Digital to Composite with Re-timing

The 5280 with the optional 5210 Genlock/Frame Synchronizer installed allows output signals to be timed independently of the input. This provides timing options for applications requiring timing to a house reference, such as the application shown below. In this case, a serial digital signal is converted to analog composite by the 5280 and feeds an analog production switcher. The input signal to the switcher can then be adjusted for proper timing with respect to other sources.

INSTALLATION

5210 Genlock Option

Plug the 5210 Genlock submodule onto the two 40-pin connectors on the component side of the 5280 Composite Video DAC module. The connectors are keyed such that the submodule can only be installed to match the connector keying.

5280 DAC Module

Plug the 5280 module into any slot in the 1 RU or 3 RU frame and install the plastic overlay provided onto the corresponding group of rear BNC connectors associated with the module location. Note that the plastic overlay has an optional adhesive backing for securing it to the frame. Use of the adhesive backing is only necessary if you would like the location to be permanent and is not recommended if you need to change module locations.

This module may be hot-swapped (inserted or removed) without powering down or disturbing performance of the other modules in the system.

CABLING

Refer to the 3 RU and 1 RU backplane diagrams of the module on the next page for cabling instructions. Note that unless stated otherwise, the 1 RU cabling explanations are identical to those given in the 3 RU diagram.

MODULE CONFIGURATION AND CONTROL

The configuration parameters for each Avenue module must be selected after installation.

This can be done remotely using one of the Avenue remote control options or locally using the module front panel controls. Each module has a REMOTE/LOCAL switch on the front edge of the circuit board which must first be set to the control mode you will be using.

The configuration parameter choices for the module will differ between Remote and

Local modes. In Remote mode, the choices are made through software and allow more selections. The 5280 Parameter Table on the following page summarizes and compares the various configuration parameters that can be set remotely or locally and the default/factory settings.

If you are not using a remote control option, the module parameters must be configured from the front panel switches. Parameters that have no front panel control will be set to a default value. The Local switches are illustrated in the Front Panel Controls and

Indicators section following the 5280 Parameter Table.

Avenue module parameters can be configured and controlled remotely from one or both of the remote control options, the Avenue Touch Screen or the Avenue PC Application. Once the module parameters have been set remotely, the information is stored on the module

CPU. This allows the module be moved to a different cell in the frame at your discretion without losing the stored information. Remote configuration will override whatever the switch settings are on the front edge of the module.

For setting the parameters remotely using the Avenue PC option, refer to the Avenue PC

Remote Configuration section of this document.

For setting the parameters remotely using the Avenue Touch Screen option, refer to the

Avenue Touch Screen Remote Configuration section of this data pack following

Avenue PC.
