The IBRit-rf1 radio module series allows the wireless transmission of measured values from gauges to a PC. The miniature radio modules are a technology step in the interface technology and replace gauge connection cables and interface boxes.

On the PC side the wireless communication with the gauges occurs via the radio module . The module is connected via an USB-Port to the PC and allows the communication with 1 ... 500 gauge radio modules. Optional on PC side the for COM-Ports is available. The assignment of the data from the different gauges occurs by address numbers. The address number and other individual radio module settings for the particular gauge type can be transmitted from the PC to the gauge radio modules and are stored there. The corresponding PC-Software is included in the delivery. The maximum transmission distance depends strongly on the environment. In free field the distance is approximately 650ft ( 200m ). The transmission of a measured value is triggered by pressing the data key on the gauge or radio module. The special data coding with a double checksum and the direct confirmation from the PC to the radio module guarantee an absolute data security. A transmission error, i.e. caused by a radio interference, is detected by the communication protocol between PC and gauge radio module. The data transmission is automatically repeated within 0,01 ... 0,08 seconds up to 3 times. A successful data transmission is automatically confirmed to the user by a green flashing light and short beep tone on the gauge radio module. If the measured value could not be received by the PC, then a red LED is flashing and two longer beep tones are informing the user about the error. In addition to the transmission confirmation the radio modules allow with a 3-coloured LED the displaying of the tolerance result from the transmitted measured value.
