The 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
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 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 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's
4000 series frame fitted with SNMP capability.
The HDA-4500 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. |
