The RFU-2400 is a 2.4 GHz radio frequency modem that is equipped with RS-232 and RS-485 port interfaces. It’s designed to act as a wireless bridge, converting a signal between serial and wireless formats, and can be used for applications without having to install wires, allowing a host and remote sensors via wireless communication.
The RFU-2400 is IEEE 802.15.4 standard, operating on the ISM bands using a transmission frequency range of between 2405 and 2480 MHz that is separated into 5 MHz segments, thereby providing 16 channels. Two operating modes are also supported, including Peer-to-Peer (P2P) mode, allowing full-duplex communication, and Broadcast mode, which allows half-duplex functionality in multi-point communication.
