Wurth Electronics’ AMB8465 wireless adapter easily connects a PC to a local 868 MHz wireless network via the USB interface. In combination with the relevant radio technology in the end device, this solution enables the quick and simple realization of PC-supported radio networks and can be used for data collection or control tasks, among other functions.
The integrated radio module enables a wireless half-duplex transmission of data. The integrated microprocessor controls all radio communication, handles packets, and checks on the formation, addressing, and monitoring of channel access and the resending of unacknowledged packets. The USB stick offers numerous configuration possibilities, data transfer with fast channel and address switching is also supported. It is also possible to assess the quality of the radio link using the measured field strength (RSSI value). The graphical user interface (GUI) of the free windows application “AMBER-ACC" allows easy configuration of the operating parameters.
Interfaces
The device is connected either via a virtual COM port or directly via USB using the corresponding software API. The USB controller (FTDI FT232R) supports USB 2.0 (full speed).
