The tRFU-2400 is a 2.4 GHz radio frequency modem that provides RS-232, RS-485 and RS-422 port interfaces. The tRFU-2400 is designed to act as a wireless bridge to convert signals between serial and wireless formats, and is great for applications when the physical wire deployment is inconvenient. The tRFU-2400 makes it easy to build a low-cost data acquisition and control application between a host and a range of remote sensors via wireless communication.The tRFU-2400 is a spread spectrum radio frequency (RF) modem based on the IEEE 802.15.4 standard. The IEEE 802.15.4 standard is operating on the ISM bands which uses a transmission frequency range between 2405 and 2480 MHz. A total of 16 channels are available and each with a channel separation of 5 MHz. Two operating modes are also supported, including Peer-to-Peer (P2P) mode, which allows full-duplex communication, and Broadcast mode, which allows half-duplex functionality in multi-point communication.
