Multi-purpose DTMF relay control

The Stheleris RRC-8D is like a swiss army knife for remote controlling technical processes. It has a 16-bit ADC LF-input to which all kind of tele-communication devices - with an ordinary audio-output - can be plugged. These can be telephones, radios, PC's with audio-out etc. The RRC-8D's asynchronous multi-threaded DTMF-decoder can be configured to interpret the input and switch 8 opto-uncoupled mechanical relays, just the way you need it.

Easy and extensive configuration

The firmware of the Stheleris RRC-8D is pre-installed and configurable just by removing the Micro-SD card and inserting it into your PC. On it you find a plain text file, which you can change to make your very own configuration. We developed a very simple imperative syntax, which allows you to reach any goal you might have. A simple example:

> DTMF 1

> PRIMARY

> activate relais 1

> deactivate relais 2

But there is more

Furthermore the Stheleris RRC-8D comes with a:

• VOX function
• DSP (Compressor, Enhancer, Bandpass)
• Audio recorder/player
• DTMF Encoder
• iTAN control protection
• Voice synthesizer

With the RRC-8D you can remote control devices, set up password protected voice-mail boxes, create radio repeaters and relays/gateways, control electric doors/gates ... or whatever you can imagine.
