Radio communication module PItract
PItract is a wireless data transmission device operating on the principle of a radio extension, i.e. transmits data packets captured via the RS-485 serial interface to the radio channel and retransmits them to the serial interface on the reverse side.
The packet capture for the protocol used is adapted by parameterizing the packet capture parameters via the device configuration settings, while the internal contents of the packet are not analyzed, i.e. data transmission via PItract between two devices via a serial interface is absolutely transparent (except, perhaps, the delay that is introduced during transmission over a radio channel).
PItract operates in the 2.4 GHz unlicensed frequency band (ISM), with a maximum power not exceeding 100 mW, so there is no need to obtain an additional permit to operate in this frequency range. Radio channel parameters, such as transmitter power, frequency channel number, modulation settings, and serial interface settings can be flexibly configured for a specific task of the Customer.
PItract is ideal for working with remote or moving objects. The applied latest LoRa transmission technology provides excellent sensitivity and noise immunity, which allows PItract to be used in industrial facilities that are in a difficult interference environment.
