Techconnect Control is the most flexible professional AV control device available. This simple control panel controls all of your AV equipment – projectors, flat panels, amplifiers, and screens – simultaneously and only presents users with the functions they use every day. No tech support calls and no losing remote controls. All in a secure Techconnect module.

Simple Mode
Hold down the two middle buttons to put into learn mode, point the original device remote at the front of the Control, and program one code per button. “Off” is pre-set to send the code twice for projectors, and the bottom buttons send codes repeatedly when held down for volume.

Advanced Mode
Alternately, connect to a PC and use included software to allocate multiple RS-232, IR, and 12v triggers to each button. Commands for each button can be sent simultaneously, sequentially, or repeatedly if you hold the button down.

Clear caps unclip off the buttons from the front to allow label changes. A set of labels are included, and users can print their own as necessary.

Backlit buttons
Backlit buttons are easy to read. If any buttons are not used blank buttons are included which block the backlight.

Once programmed, a schedule can be setup. For example turn the digital signage in a store off at midnight every night.

Commands can be delayed up to 60 seconds. For example when you turn a projector on it takes time to warm up so the motorised screen doesn’t come down until the projector is ready.

Programs can be saved to a PC making duplication for a roll out simple.

Extension Keypad
If more than six buttons are required the software allows you to add another Control as an extension keypad which connects to the master via RS485. All commands are still held and sent by the master Control.

TC3-CTLCode Library
An integrated library of IR and RS-232 codes speed programming up. For example if you learn the codes for a projector those codes will be automatically uploaded to the database so that the next installer who needs those codes will find them in the software library.

Alternative Code Learning
IR codes can be added by using the original remote, or by copying and pasting the hex code if you have lost the remote.

The Control comes with a mains power adaptor, but can also be powered by 2 x AAA batteries (not included). A switch under the batteries selects the power source. Note: when running on battery backlights do not stay lit and 12v triggers will not be sent.

The IR receiver for learning codes is on the front panel, and is accompanied by an IR emitter which eliminates the need to run an IR cable in smaller rooms. Two external IR emitters are included; one with a 10m cable, and one with a 200mm cable.

RS-232 and 485
These two protocols use the same codes but RS-485 only requires two cables and can be run a longer distance. Note: a projector with an RS-232 port will not be able to decode RS-485 signal.

12v Trigger
Many projector screens can be controlled with a 12v (2.4w) trigger voltage. Note: Many projection screens with remote controls use RF which cannot be learned or sent by the Control.

Easy Wiring
To speed up installation it comes with a short 9-pin serial cable which plugs into the phoenix port on the Control.
