The decoders can detect two standard types of communications signals.
1 - DTMF:
To send the Dtmf control code to the RXC you can use a normal encoder such as a dispatch console, a dedicated encoder or a portable radio with a Dtmf keypad.
2 - Two-tone
If you are starting with a new system you can develop your own paging and activation code scheme. Feel free to contact us if you would like some assistance in working it out.
If you intend to add an RXC into an existing code plan, you will need the tone frequencies and timings if using tone paging, or the Dtmf code strings if the system employs Dtmf signaling. If may be necessary for you to work with the activation agency or local radio service shop to coordinate the codes and pages to ensure there is no overlap.
The RXC-3000 also has features which let you verify and program the signals you receive over-the-air. The "Learn" mode detects the Two-tone or Dtmf command and assign it to a particular action. In addition, the "Live TTS" and "Live DTMF" menu items let you verify the signals and optionally record them to the log memory, or send the data to your computer screen for further analysis.
Yes. There are two ways to do this.
1) Without a computer.
2) Use your laptop.
Each relay on the RXC can switch devices and equipment which draw up to 10 amps of power.
Controlling lights, motors or other devices which need more than 10 amps is very easy. You just install a relay which can handle the necessary power, and wire the RXC to turn on and off the relay. In heavy duty applications, the relays are called "Contactors" or "Motor Starters".
Depending on your application, you may need to consult a qualified electrician to determine the correct size for the contactor. Your local electrician or electrical supply house may also have the contactor you need, or you may want to check www.AutomationDirect.com as a source for contactors and cabinets for heavy loads.
Yes. Encoders from Whelen Electronics transmit DTMF signals at a faster than normal rate. RXC decoders have no problem understanding signals even at this faster speed. Click Here for additional Dtmf timing information.
The processor, radio and all the parts of the RXC operate on 12 volts dc voltage. Since the RXC is usually installed where dc voltage is not available, a high efficiency voltage converter is installed which changes AC voltage to DC voltage. The converter will accept any AC voltage between 95 vac to 240 vac, and automatically change it to the necessary 12 volts dc. The converter also accepts either 50 hz or 60 hz power. The RXC can be "hard wired" by an electrician using conduit or flexible raceway, or many users simply attach a flexible cord to the RXC so it can be plugged directly into a standard receptacle.
Other types of power converters are also available including wide voltage DC-DC converters, isolated DC converters for railroad applications, and solar power converters.
Our radios are FCC and Canandian type accepted and registered. We welcome orders from Canada as well as other countries around the world..
