T430
The T430 is a budget-priced wired (RS232 and
limited IR) remote controller for video projectors
and flat panels, allowing just simple On-Off
control, and an option of a basic toggle
channel/source selection.
This is done with just two push-buttons, as the
photo shows: just Off/On or Off/On-Source.
Ease of setup and installation has been an
important design criterion, and this has been
achieved by providing a data-base of pre-coded
projector code families in all units, so all have
identical software (which is field up-dateable).
At install time, or whenever options (or
projectors) are changed in a room, the changes are
made by selecting device families with hex
switches on the back of the unit.

T440
The T440 is a lower cost RS232 remote controller
for LCD and DLP video and data projectors, LCD and
Plasma flat panels, for budget installations in
lecture theatres, classrooms, churches or
conference rooms.
The JED T440 projector controller (and optional
T441 or T461 audio controller) offers a convenient
system to control video and data projectors from a
suitable point on a lectern, bench or wall near a
speaker's location in a hall or theatre.
Alternatively, the controller and front assembly
can be mounted on a black or white Clipsal 2000
base block, and can be wall mounted near the
operator's position.
A 45 degree white or black metal case is also
available.
The T440 has an attractive white, or black, smooth
escutcheon surrounding it, to give an overall size
of 110mm by 70mm. This covers the screw holes and
can be mounted into a lectern or desk at a
convenient point for the speaker to control video
and data projector operations. As an option, just
the adhesive backed keyboard and electronics board
can be supplied without a Clipsal plate, to allow
installers to mount the system on their own panel
to match the decor of media control desks or wall
plates in boardrooms, etc.
The T440 is wired back to the LCD projector via an
RS232 data cable, needing only three wires (TX, RX
and Ground). (A connection for a fourth wire with
9 volts on it is available as a CTS or DTR line
HIGH to the projector to enable RS232
transmission, as some projectors expect this input
to be HIGH before allowing transmission.)
The control codes for different projectors are
programmed into the T440 controller, and the
projector family needed for a particular
installation is selected on the rotary switches on
the back. Keyboard type and options are selected
on other switches on the back.

T460
The JED T460R projector controllers offer a
convenient system to control video and data
projectors from a suitable point on a lectern,
bench or wall near a speaker's location in a hall
or theatre.
The T460R is a new version of this, released
September 2011, which replaces the back-lit LCD
display with a self-emitting OLED display, giving
much higher visibility and better viewing angles.
It adds the option of four N-FET "relay" outputs
which can be used to drive screen controllers,
projector "dippers" and room light- dimming
controls.
The front panel keyboard of the T460R is shown
above, is 76mm by 58mm, and is mounted on either a
white or black Clipsal 2000 series blank power
point base or grid plate. Behind the window is a
two-line OLEDscreen showing system status. The
T460R has an attractive white, or black, smooth
escutcheon surrounding it to give an overall size
of 110mm by 70mm. This covers the screw holes and
can be mounted into a lectern or desk at a
convenient point for the speaker to control video
and data projector operations. Alternatively, the
controller and front assembly can be mounted on a
black or white Clipsal 2000 base block, and can be
wall mounted near the operator's position.
As an option, just the adhesive backed keyboard
and electronics board can be supplied without a
Clipsal plate, to allow installers to mount the
system on their own panel to match the decor of
media control desks or wall plates in boardrooms,
etc.
The T460R is wired back to the LCD projector via
an RS232 data cable, needing only three wires (TX,
RX and Ground). The control codes for many
hundreds of projectors are programmed into the
T460R controller, and a variety of customising
set-ups can be performed on the unit via the front
panel keys to select different projector makes and
models, and then to name video sources from a menu
and allocate them to various input channels on the
projector.
The control of audio level can be done in the
projector, and audio control signals are sent to
the projector along with the video source and
power control signals. If a T461 audio rack is
installed, it is controlled with a second serial
port on the T460R, and the T461 selects and
controls the audio levels in step with source
select signals sent to the video projector.
Optional keyboard background colours and keyboards
are available.
The standard key-labels for the right-hand keys
are "VOLUME UP" and "VOLUME DOWN".
