User Manual  

GENERAL:

The DDA-4010 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 DDA-4010 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 DDA-4010 can be run independently allowing a mixture of signal types to be used.

The DDA-4010 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 panel LEDs indicate when input signals are present and whether the outputs are locked to the inputs.

Optional relay bypass rear assemblies are available to switch the Inputs to one of their respective Outputs in the event of a power failure.

Simple Network Management Protocol (SNMP) is available for remote setup and monitoring of input status and alarm states when used in an IRT frame fitted with SNMP capability.

The DDA-4010 is designed to fit IRT's 4000 series 3RU frame for use with IRT's SNMP system as well as being suitable with IRT's 1000 series 1RU Eurocard frames and may be used alongside any other of IRT's Eurocards.
