The AMB8376 Long-Range Radio Modems provide an easy-to-use, long range, multi-channel serial data communications link for a range of up to 18 km at line of sight or up to 3 km indoors. The modem transmits and receives half duplex serial data at rates of up to 19.2 kbps (over-the-air data rate) by means of a FM Radio Transceiver operating in the 869 MHz frequency band. It can operate as a one to one cable replacement link, in multiple master/slave arrangements or in broadcast modes.

A 8K buffer memory is provided to enable the RF modem to transmit and receive data independently of the host controller without the need for handshaking. The CTS/RTS signal may be used for flow control in duplex applications.

The radio modem parameters can be configured via serial interface by making use of AT commands or AMBER ACC software. Data can be formed into packets and passed from one modem to another. If a received data packet contains any error, then the data packet will automatically retransmitted. Both, size of data packets and number of retries are configurable. The host controller communicates with the AMB8376 radio modem using data rates between 1.2 kbps and 115.2 kbps.
