The FRPC2 is intelligent transceiver modules which enable a radio network/link to be simply implemented between a number of digital devices. The module combines a UHF BiM2-433-160 radio transceiver and a 160kbit/s packet controller.

INTRODUCTION
The FRPC2 is a self-contained plug-on radio port which requires only a simple antenna, 5V supply and a byte-wide I/O port on a host microcontroller (or bi-directional PC port). The module provides all the RF circuits and processor intensive low level packet formatting and packet recovery functions required to interconnect an number of microcontrollers in a radio network.

A data packet of 1 to 60 bytes downloaded by a Host microcontroller into the FRPC2's packet buffer is transmitted by the FRPC2's transceiver and will "appear" in the receive buffer of all the FRPC2's within radio range.

A data packet received by the FRPC2's transceiver is decoded, stored in a packet buffer and the Host microcontroller signaled that a valid packet is waiting to be uploaded.
