User Manual  


The IRT-6010-DDA serial digital data distribution amplifier provides the user with a single module to cover a wide range of distribution and monitoring functions for 3G/HD/ SD-SDI or ASI signals.

Two quad output reclocking / non-reclocking distribution amplifiers are provided on the one card. On board switch settings allow either of the inputs to feed all outputs to create a one in, eight out distribution amplifier.

Where non-reclocking is required, on-board switch settings select between reclocking and non-reclocking modes.

The IRT-6010-DDA will automatically reclock to match the input at either 3G SDI, HD SDI, SD SDI or ASI rates, or can be fixed to operate at any one of these rates. Both sides of the IRT-6010-DDA can be run independently allowing a mixture of signal types to be used.

The IRT-6010-DDA is also configurable for automatic changeover from one input to the other on loss of input signal allowing for an input Main/Standby scenario.

Due to the nature of ASI signals being phase sensitive, signal inversion is also possible for situations where an inverted ASI signal needs to be corrected.

Front edge LEDs indicate when input signals are present and whether the outputs are locked to the inputs.

An optional relay bypass rear assembly is available to switch one of the Inputs to one Output in the event of a power failure.

The IRT-6010-DDA is designed to fit the openGear® standard 2RU frames which allow a mixture of cards from various manufacturers to be mounted within the same frame.

The DashBoard™ control software is available as a free download.
