Henrik Torp Nielsen - Bang & Olufsen America:
The support is A+++. The TT455-RT-238 is brilliant.
I have no software experience, but with this product I am controlling a plasma screen and a DVD player, that was just a quick test, the product is able to do so much more. The TT455-RT-238 is highly recommended.

Can also be operated by a B&O remote


BeoRemote One



Tested by Flatpanels

Very easy configuration - try it here.


Power supply

TT455-RT-238 can be used all over the world, since it is powered by a 12 volt dc adaptor.


IR Low-Power Output 1

Insert a TT-IR-ET03 - if you want to control products in a closed cabinet.
The IRLPO1 is part of the integrated IR distributor.


RS232 Comport

We offer a well-dodumented communication protol allowing you yo send IR from computers
like Crestron, Masterlink Gateway, etc.
Our Command 915 allows integrators to read all incoming Triggers.



An integrated BootLoader allows you to update the firmware


Digital in/out

Digital inputs allow the TT455-RT-238 to be controlled by buttons, switches, relays, etc.
The digital outputs can control relays directly .


IR receiver buttons input

Factory feature for this programmable socket is to read the buttons on the external B&O IR receiver. Very nice feature if the remote control is misplaced.
Alternatively it can be programmed to be a seconday IR lower power output.


IR low-power output 2

Insert a second TT-IR-ET03 - if you want to control even more products in a closed cabinet.
The IRLPO2 is part of the integrated IR distributor.


External IR receiver input

Socket for external IR receivers. This is where you would insert the B&O IR receiver.



Very powerful Atmel MEGA2561 micro-processor



The micro-processor holds your configuration and controls all Trigger/Actions handling.


Memory Map

You can change your configuration and add/remove new products/commands


High-Power Front IR Booster

High-Power Wide-Angle Dual-Band IR Booster
