Jed T460 Controller

T460, a low cost RS232 remote controller (and timer) for LCD and DLP video and data projectors, LCD and Plasma flat panels, for lecture theatres, classrooms, churches or conference rooms.

The JED T460 projector 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.

The simplicity of operation of the T460 is its major advantage when installed in locations where a number of users/teachers/lecturers who are unfamiliar with A/V equipment, and without an audio/visual assistant/operator, need to run a "show".

They need to power up the projector, select a source, run a video or computer presentation or demonstrate some other program, or display a feed from a document or microscope camera on the video screen, and then close the system down again. Contrast the four buttons on this unit with the 20 or 30 on some IR remote controls, each one different from room to room. This unit is identical from room to room, even with a mix of different projectors.

And when the show is over, T460 controller does not walk out the door in the lecturer's pocket like IR remote controllers often do!


Jed T461 Audio Attenuator/Mixer

This T461 option has eight relay contact outputs which can be used to control screen up/down functions, projector access hatch controls, scissor jack lowering actuator, room lighting preset selects, etc. The relays are also controlled via the RS232 secondary link from the T460 to the T461. The relay states are displayed on front panel LEDs. (A future, taller, T461 version could include 50W stereo audio
amplifiers for complete theatre functionality.)
