HDA-4500 1.485 Gb/s serial digital video distribution Amplifier provides the user with a single standard module to cover a wide range of distribution and monitoring functions for High Definition (HD) digital signals.
As well as accepting an HD signal, the HDA-4500 1.485 Gb/s serial digital video distribution Amplifier will also accept Standard Definition (SD) rates such as SDI. ASI is also possible, however as three of the six outputs are inverted only the non-inverted output ports are suitable for ASI.
Serial digital signals suffer severe deterioration over relatively short cable distances. This is especially so with the HD high data rate.
The HDA-4500 1.485 Gb/s serial digital video distribution Amplifier provides a means of extending the working distances that can be achieved by equalising and re-transmitting the data mid route.
An on board link sets whether the HDA-4500 high definition 6 O/P distribution Amplifier will accept a either 1.485 Gb/s HD signal or a lower rate SD signal by adjusting the output driver slew rate to suit.
Front panel LEDs indicate when an input signal is present and also whether the on board link is set for HD or SD operation.
A relay alarm output, with a selectable N/O or N/C switch to ground contact, is available for indication of loss of input signal or loss of power.
An optional SNMP (Simple Network Management Protocol) plug in module is available for remote monitoring when used in conjunction with IRT Electronics ’ 4000 series frame fitted with SNMP capability.
The HDA-4500 1.485 Gb/s high definition 6 O/P distribution Amplifier is designed to fit IRT’s 4000 series frame for use with IRT’s SNMP system as well as being suitable with IRT’s standard 1000 and 3000 series Eurocard frames and may be used alongside any other of IRT’s analogue or digital Eurocards.
