T460R: Serial projector controller with OLED text display
Go to T460R
This controller has two RS232 serial ports for device control, and provides user messages on a bright OLED text display to inform users of system status (warm-up, cool-down, current source (by user-defined name), current audio volume (numerically) and mute and freeze status.) The display also shows lamp and filter hours, and can control aspect ratio, microphone volume and the screen.
Setup is done on-board after entering a pin number, giving access to 18 menus, much like a mobile phone. Users can roll the current source through up to eight channels. (Unused ones are skipped.)
The new T460R-R4 (option) has four N-FET 'relay' outputs for screen control, dippers and room lamp dimming. The use of these "relay" outputs can be altered during the setup process, and they could be actuated for a particular source (e.g. to operate a video switch or USB switch) or used to turn on system, audio amplifier or projector mains power when the ON button is pressed, and turn it off at the end of the OFF countdown time.
T460R units are available with a range of keyboards ... three sample ones are shown in these photos. The "metallic" one looks great on boardroom walls, and the other two have been popular in schools and universities.

T470 family: Corporate 4, 6, 8 or 10 button controllers
(New product, initial release Jan 2012) Go to T470
The JED T470 is a new controller from JED, manufactured in Melbourne, and designed to run simple Audio/Visual installations in an intuitive way.
It communicates with the projector or LCD panel via RS232, but an IR option is also available. It fits in standard Australian power point fittings, but by design does NOT have a removable front, suiting certain Australian state requirements for school use.
It is much simpler to use and set up than LCD displays and provides keys, which can be relabelled to suit the installation, and a switch action with a mechanical “click” to the operator’s finger. White indicator LEDs show channel selections above each key. (It is available with four, six eight or ten key options, and a white or metallic case finish.)
The T470 controller can be used stand-alone as a simple, low-cost controller, or teamed with a T452 expander box. This option provides screen relay outputs, security and PIR inputs, IR outputs, and extra ports to talk to video switchers, audio mixers and amplifiers. Two T470 controllers can run via one T452, giving a master-slave setup from two points in a hall.
No programming is needed … setup is done via the keys, via a PC application or via switches on the T452 expansion unit. Each unit contains a data base for hundreds of projectors and panels. |

T440 family: Economical 4, 6 or 8 button controllers
Go to T440
These controllers use red and green LEDs to show system status, and select between one to five sources for the display device. They also have two RS232 serial ports, controlling the display from one and auxiliary audio controllers, relay boxes or USB switchers from the second port. There are also three "'Relay" outputs for screen control and either a USB switcher control or system power control.
Green LEDs flash during warm-up or during channel change, and a red LED (by the OFF button) flashes during cool-down. Source buttons can be single hit (Computer, Video) or can be double-hit, so pressing a button again toggles between Computer1/Computer2 or between Video1/Video2. Yellow buttons control audio level, either in via the projector, or via an external audio mixer/attenuator. See the T441 or T461. (Pressing both yellow keys together provides audio/video mute.)
The eight-button version provides for a TV source as well, and two extra (blue) keys are provided for TV channel Up/Down control as well. It also provides one or two Computer channels and one or two Video channels .
Setup of a T440 (and the T430, following) is simply done by setting a two-digit display device code into rotary numbered switches on the back. Other options are set on a DIP switch.

T430: A low cost, simple controller with one or two sources
Go to T430
This simple 2-button controller is usually associated with Interactive Whiteboards, where it simply controls projector On and Off functions.
Two keyboard options are available: KB1 has just On and Off keys, and KB3 option allows the On-Source key to toggle the projector between a primary source (e.g. computer) and a secondary source (e.g. a laptop or a DVD player.) It has only one serial port and no screen control outputs, although it has a "relay" output which can be used for either a USB switcher control or system power control.
It has a PIR input to provide automatic projector closedown if everybody leaves the room without manually shutting the system down.
