AMB8465 Wireless 868 MHz USB Adapter Proprietary radio data applications Key Features * USB version of the OEM radio module AMB8425 * Range up to 100 m * Communication via virtual COM port * Integrated software stack with comprehensive range of functions * Flexible addressing and network topologies with up to 255 nodes in 255 networks * Configurable data rates and RF channels Network Topologies Description The AMB8465 is a variation of the low cost radio module AMB8425 for easy connection to the PC via the USB interface. In combination with the relevant radio technology in the end device, this solution enables quick and simple realisation of PC supported radio networks and can be used for data collection or control tasks. Point-to-point The integrated radio module AMB8425 enables wireless half-duplex transmission of data. The integrated microprocessor controls data communication, handling packet and checksum formation, addressing, monitoring of channel access and resending unacknowledged packets. The host system does not have to perform any radio-specific tasks. The USB stick offers numerous configuration possibilities and 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 of the free windows application "AMBER-ACC" allows easy configuration of the operating parameters. Interfaces Point-to-Multipoint 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). Supported operating systems The drivers required for the virtual COM port are available for Windows, MAC and Linux at http://www.ftdichip.com. Scope of Application Data collection, monitoring, remote control and sensor networks. Peer-to-Peer Specifications Performance Radio Technology Range* up to 100 m RF data rate up to 500 kbps Addressing up to 255 nodes in 255 networks Frequency range 863.0 - 868.6 MHz Channel spacing 50 kHz Modulation type 2-FSK, MSK Supported topologies Point-to-Point, Point-to-Multipoint, Peer-to-Peer * Range stated is calculated assuming line-of-sight. Actual range will vary based upon specific board integration, antenna selection, and environment.
