Tira-2.1: Remote Control Receiver/Transmitter

Available Now

In many situations, it is necessary to be able to transmit IR signals from a PC. For example, if you use a PC as a TIVO or ReplayTV device, it would be great if a PC could automatically switch channels on a cable box. Also, in many home automation applications a PC needs to control various equipments around the house. Most of the equipment can be controlled by IR signals. That's why we decided to develop Tira, the Transmitting InfraRed Adapter.
It works with a popular program Girder and allows to capture IR codes right from the original remote and reproduce them later. Of course, it allows you to control applications running on a PC, as Ira-2 does.

62x40mm

Features

USB interface for easy installation
Remotely wakes up PC from standby mode
Receives and transmits arbitrarily long sequences
Two IR LEDs will provide higher power, allowing you to control equipment from a greater distance
3.5mm jack for connecting additional IR emitters
Transmitter supports wide range of modulation frequencies: 18-80kHz
Capable of "learning" IR codes in the same range of frequencies
Compatible with most existing remote controls (see details)
Compact and elegant design

Principal Parts

Two IR LEDs for transmitting IR codes

Short range sensor for capturing IR codes

Long range, 38KHz IR receiver

USB "B" Connector

3.5mm jack for connecting external emitters (Center pin "+", sleeve "-")

OEM Version

Tira 2.1 OEM version is the same device electronically, but comes without a plastic enclosure. It is intended for installation inside a PC. Four pin (0.100" spacing) USB connector is provided, and external emitter can be connected to the two pin connector. Click here to view mechanical dimensions and layout of the Tira 2.1 OEM board. 1.5ft USB cable for connecting to mainboard is optionally supplied.

Remote Control Extender

Tira can be used as a remote control extender. If you connect another Tira (or Ira-2) to the same computer, the second device can be used as an IR input, and all IR codes received by the second device will be immediately reproduced by the main Tira.
This way not only you can control your PC from two rooms, but also control all other equipment from two rooms. read more...

Remote control Compatibility

Tira is designed to work with most remote controls. In fact, we believe it will work with ALL remote controls using modulation frequency in the range of 32kHz to 42kHz. Is it good or bad? Well, at this time we know of only two companies that use frequency out of the range. Those are "Bang & Olufsen" and "Vidikron". All other brands must work.
