General
The DDS-3031
RS422 / RS485 bi-directional data switcher
is part of a family of "smart" switchers in
Eurocard format which may be linked and
configured by the user to cover a wide range
of switching and monitoring functions.
On board links allow several switchers to be
joined for 10 x 1, 15 x 1 or 20 x 1
operation.
The switcher may be slaved to operate in
conjunction with similar switchers for
analogue video, stereo audio and serial
digital video.
This makes the DDS-3031 ideally suited to
situations such as editing suites where
control signals need to be switched either
individually or in conjunction with video
and audio source selection.
Only the selected bidirectional path is
active at any time with unselected data
outputs reverting to tri-state. This allows
switchers to be used in multiple
combinations (subject to logical conflicts.)
The CPS-3050
local control switch panel kit converts the
switcher for stand alone operation.
The CPS-9001 remote control panel provides a
5 button control with on board addressing to
allow formation of 10 x 1, 15 x 1 or 20 x 1
combinations. The switches have tally LED's
and label inserts. Multiple panels may be
used with tally to each panel.
The DDS-3031 is fabricated in IRT's standard
Eurocard format and may be housed in a
variety of IRT Eurocard frames alongside
other standard modules.

General
The AMS-4370HD is a magnetic latching 4 port
changeover switcher using enhanced performance
relays which provide switching capabilities for
high speed data signals up to 1.4 Gb/s. It is
suitable for switching high definition video,
ASI, SDI or G.703 data streams or analogue video
signals, provided that they have characteristic
impedances of 75Ω.
The AMS-4370HD is arranged as a changeover
switch with two inputs and two outputs. No
terminations are provided on the board allowing
the switcher to be used in a wide variety of
applications and with signals of various types
and impedances.
The magnetic latching characteristic of the high
performance relay allows momentary control and
also provides for no change of path during power
loss. Remote changeoverchangeover is by a
momentary ground connection.The AMS-4370HD is
ideally suited to applications where a simple
choice between two inputs or outputs is required
and may be easily driven by detector circuits
for automatic path selection.
For best performance the outputs should be
connected to inputs with automatic cable
equalisation.
Remote indication of tally and local/remote
status is provided for integration into central
alarm and monitoring systems.
The AMS-4370HD relay card is built to the
Eurocard format and will mount in an IRT 1RU or
4000 series 3RU frame.
