Ripple Control Receiver and Tone Frequency Receiver (HKV-RKV)

RKV and HKV device family

Prolan has developed its own device compatible with “Type-B” radio ripple control systems called PROLAN Radio Ripple Control Receiver (RRCR-B).

Devices developed and manufactured by Prolan are compliant with industrial de facto standards:

  • Integrated long wave radio receiver and switching clock function controlled by a microprocessor
  • Suitable for every traditional long wave controlling and switching tasks as well as for the combination of these functions
  • In case of disconnection of the long wave control it can be used as a switching clock
  • Compatible with multiple data transmission protocols

One main feature of the devices manufactured by Prolan is locating the direction of the optimal signal strength automatically. This functionality facilitates the mounting and maintenance tasks of the system.

The second generation of the device has been available since the spring of 2009 equipped with three output relays according to the Hungarian needs and Type-B protocol. Another version of the product is available equipped with 6 output relays. Both versions are also available with the Versacom protocol.

The refined versions of the devices have been available from the beginning of 2010 which can be located anywhere in the reception area of the transmitter, or can be used for controlling street-lighting systems. Development of software used to configure, test and manufacture the device was an important part of our work. The RCM test device with signal level measurement and transmitter unit facilitates the commissioning of the system.

USB Optical Reader

The USB optical reader allows reading of standard measuring systems quickly and easily, such as our RKV family of devices. Product Features: Thanks to the infrared transmission, the optical reader and the measuring device are galvanically separated. The LEDs on the backside show the operation of the device: send - green LED, reception - white LED. Connecting the USB connector most operating systems recognize the device as a virtual serial port, but in the event of an error, download the driver from the following link:  


RCM is a device for installing and testing RKV receivers manufactured by Prolan Inc. The device supports Type-A and Type-B. The RCM can also be used as a radio station so the RKV receiver can be tested even if the broadcast is paused or is of poor quality. The RCM can transmit any telegrams to the RKV receiver within 1 meter radius. During production, both the transmitter and receiver frequency can be set to the frequency of the Burgi, Lakihegy, and Mainflingen radio stations. Features of the unit: Check the functionality of the RKV receiver, check its functionality Analysis of the surrounding radio field and noise spectrum Send long-wave wireless telegrams Query the parameters of the device Download new firmware and parameter settings in a documented way Another unique feature of the device is the radio field and noise spectrum analyzer. It helps to detect environmental radio signals and noise that can be seen in graphical form, which affects the reception of RKVs. The device can modify the operating parameters of the exchangeable software on a pendrive. Newer software can be downloaded from the website so that changes made by the manufacturer Prolan Zrt. Can be followed. The box of the device is resistant to mechanical stress and is watertight in the circuit except for the connectors. It is powered by 4 AA batteries with up to 10 hours of continuous operation. The batteries can be charged with the supplied charger within 1-2 hours, but the device can also be used with an external power supply.
