Projector Controller

Demonstrating the JED T440
• T440 is a budget RS232 wired controller with
status LEDs and a variety of keyboards;
• LEDs flash during warm-up/cool-down lockout;
• Communications status read by pressing OFF.
Choose your keyboard
Code 2
Code 0
• These four are
the initial release:
there are now 9
in the family;
• Four-key for
simple ON plus
volume, or ON
with simple
channel select;
• Up to 8 keys, so
can control
screens, TV
channels etc.
Code A
Code 9
Off key/LED: Quick system check
Code 0
• The OFF LED shows in the “rest” state;
• The OFF button can be pressed in the OFF state, and
the T440 polls the projector. If the projector replies
correctly, the OFF LED flashes once;
• If NOT, it flashes three times.
ON key: System starts
Code 9
Pressing the ON key starts the projector, and the ON LED
flashes during warm-up.
The last used channel LED also glows, showing where the
system will start after warm-up (“Video” in photo.)
(An alternate channel can be chosen during warm-up, and
this LED now glows.)
System running
Code 9
After warm-up is complete, the channel setting message is
sent to the projector, as indicated by a lit channel LED.
(At this time the channel LED flashes briefly.)
Pressing another channel key changes to a new channel,
and this channel LED now pulses, and then glows.
Audio control: The yellow keys
Code 9
The yellow keys control the audio volume, either in the
projector, or the external T461 audio controller (see later).
If BOTH yellow keys are pressed together, the audio and
picture mutes. Pressing a yellow key, the ON key or the
active channel key restores both picture and sound.
Combined On/Channel key systems
(Code 5 keyboard)
(Code B-L
“landscape”)
(Code B-P
“portrait”)
Note how three keys have combined ON and channel functions. Use
these if there are two computer/VGA channels in an install.
An alternate channel can be chosen during warm-up, and this new LED
now flashes during warm-up, and then remains lit after startup.
Double-function options on source keys
by setting OPT4 switch ON
Four key, code 0
Six key, code 9
Six key, code A
Eight-key, Code E
These (above) normally give two main channels,
Computer:1 and Video:1.
With OPT4 set, each button can be pressed again
to select secondary channels, i.e. Computer:2
(eg Laptop) and Video:2 (eg S-Video)
(Note: After changing between Computer/Video, the
system defaults to the primary source for that key.)
Four key, code 2
OPT4 gives toggle between
two computer channels
Freeze-Mute
keyboard
Code A keyboard
Note the 45 degree
metal case, (available
in white or black.)
When running, this option allows the user to freeze
the display or mute the picture.
(Assumes the audio is handled externally.)
At the end of the show:
Just press OFF
Code 5
The red LED flashes for the length of the programmed
cool-down period, and then goes into steady OFF state
ready for the next cycle. (Warm-up and Cool-down time
can be manually entered at setup.)

Options SW2 SW3
Option switches 1 to 8 for special
functions, e.g. select S-Video, auto
pixel align, PIR/Timer start,
double-hit mode, reply mode,
T441/T461 audio, etc
Sw2 & 3 to set projector family code
MUST be set at install time by tech.
(This unit set to 12 hex, i.e. NEC 9600
baud family. See part B of manual.)

Passive Infra-Red (PIR)
This sensor can reset an
PIR input
internal timer, so the projector Ground
keeps running while students
are present, but it times out
and turns off when everyone
has gone home!
The PIR can also start a
projector when people enter
a show-room or gallery.

T441/T461 audio mixer / attenuator
Used if the projector:
• Does not control audio;
• Has not enough inputs; or
• Has no audio output.
T441 2-channel audio system
Four stereo lines in, one
stereo line pair out to amp.
T461 4-ch. audio system

JED 439 USB switcher
Used to switch the USB ports
from two computers in a
classroom so that either can
control an Electronic Whiteboard.
RS232 to JED439
Ground
TX command to JED 439
RX reply from JED 439
The 439 switches USB Whiteboard control
between a classroom PC and a teacher’s “guest”
laptop, when the T440 selects Computer:1 or
Computer:2. Control can be via RS232, via
contacts or via auto-sensing of 5V on the line.
It can disconnect control when Video is selected.

T440 back view: Connections 8
Easy connection option: Plug in a CAT5 cable as the
only connection from the T440 to the projector.
Then run power, RS232, PIR all down the one cable from a plug pack up
with the projector.
Or use the new T447 (below left) to connect it all together up the top,
including a signal tester. (See the LEDs which flash with communications.)

with audio control is needed.
Eight-key TV controller, Code E
This adds channel change for flatpanel TV displays, to control tuners.
How to choose a keyboard 2

These three give three channels, and have audio control
Software for the T440
The software for the T440 contains drivers for all covered projectors
and flat panels, and the code set onto the two rotary switches selects
a driver, with options for baud rate and minor code differences.
There are no specific models selected by number, as in the T460,
rather many models are covered by each setting. Typical models are
noted in the user’s manual and the “covered projector” lists by release.
One big advantage of the T440 is that you never have load each
controller at install time from a lap-top or by capture
from a hand-held IR remote … just set the switches.
As JED includes new drivers,
these are made available to
distributors, and an older T440
can be updated and a new
driver then selected.
The cable plugs into the T440’s second serial port.
JED controllers T460 and T440
The T460 is our high-end model, with a text LCD display, showing
channel names for up to eight channels. Lamp hours are displayed
at start-up, and warm-up and cool-down times are counted down.
This unit can drive the T461 audio box, and a variety of mixers and
relays for external signal control. Swipe card readers, PIR and timer
inputs are also provided.
The T464 network box allows remote monitoring from a tech centre.
