A ready to use receiver interface for secure RF remote control
31 August 2010
The new KDEC code hopping receiver from Radiometrix is offered with a basic antenna and provides the user with a complete ready to use receiver interface, enabling quick and easy deployment of a secure RF remote control system. The ever changing 32 bit encrypted hop code is encrypted using 64 bit manufacturer code and 28 bit serial number for security.
The decoder has a standard frequency of 433.92MHz, though other frequencies can be offered on request. It is optimised for use with the company’s KFX2 key fob transmitters or KTX2 transmitter modules. If combined with either of these products, no additional parts are needed to create a wireless system suitable for high security remote control. The erasable secure learn function allows up to 16 different transmitters to be remembered.
When optimised for the five-button KFX2 transmitter, it is not possible to activate more than one output per transmission and all five of the KDEC’s 250V 8A relay outputs can be individually activated. Alternatively, when optimised for use with the KTX2, the KDEC has simple output functionality. New function-codes are fed to the relays as they are received. For both versions, momentary/latched relay action is also selected by means of a jumper link on the PCB. LED based visual indicators show which relays are in operation. The receiver is powered by a 9-16Vdc supply.
