Imagine SEL-DDA1-EES DUAL DA, D TO A, HD-BNC IN/OUT; Dual...

• Dual D to A conversion
• Single/Dual SDI/ASI DA function
• Single/Dual SDI/Monitoring DA function (for SD)
• Small SDI/ASI routing switcher function
• Optional relay bypass (dual-channel capability)
• Optional SFP for optical input and output
• Optional MAGELLAN remote panels for control and monitoring

The DDA may be placed in any open Selenio slot and has its own block diagram User Interface.

If used as a VEX, it must be installed beside a frame sync or video conversion applications module and will automatically be connected. When viewing the front of the frame, the DDA is placed to the left of the FS/XD applications module (lower slot number). The block diagram in the FS or XD User Interface is updated giving the user setup, control and monitoring functions. Five back module options provide interfaces for electrical and optical inputs and outputs and relay bypass for critical signals upon power loss — one with HD-BNC electrical connections for input and output; one with HD-BNC electrical connections for input and output and dual relays; one with a dual SFP optical input with HD-BNC outputs; one with HD-BNC inputs with two dual SFP optical outputs; and one with a dual SFP optical input and two dual SFP optical outputs.

SDI interfaces utilize a Belden-type 1505A, 1694A or 1695A cable (or equivalent) with HD-BNC connectors. HD-BNC to BNC adaptor cables and a cable insertion/removal tool are available for the HD-BNC connections.

Adding Analog Composite Outputs to the Selenio Platform
The DDA’s primary function is to add two analog composite outputs per DDA module to the Selenio platform. Within the DDA, it is possible to convert one or two 270 Mb/s SDI (electrical or optical) externally connected or one internally connected (any slot in the frame) to two analog composite outputs. For HD down conversion to analog composite output, the XD module is required.

SDI/ASI Distribution Amplifier Function
The DDA can be setup to operate as a single or dual channel SDI or ASI distribution amplifier.

SDI/ASI Small Routing Switcher
The DDA can be setup to operate as a small routing switcher for SDI or ASI.

Electrical/Optical Interface
The DDA can be used as a single or dual channel electrical to/from optical interface.

Relay Bypass
As well, for critical paths to pass program signals upon loss of power, relay bypass is a requirement. The DDA supports a version for dual replay bypass for SDI upon loss of power.

The DDA can be used to provide a “passive loop through for the ENC module” by taking the program signal into DDA bypass relay input and then taking the program signal from the bypass relay output to wherever it is needed in the system design and one of the active outputs can feed the input of the ENC.

MAGELLAN remote control panels can be set up to access all parameters for Selenio processing modules. The panels with an OLED display and rotary control add the capability to make adjustments with the rotary control and view the parameter changing and view status parameters.
