RPC-418-40 and RPC-433-40 are intelligent transceiver modules which enable a radio network/link to be simply implemented between a number of digital devices. The module combines a UHF radio transceiver and a 40kbps packet controller.

INTRODUCTION

The RPC 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 inter-connect an number of microcontrollers in a radio network. A data packet of 1 to 27 bytes downloaded by a Host microcontroller into the RPC's packet buffer is transmitted by the RPC's transceiver and will "appear" in the receive buffer of all the RPC's within radio range. A data packet received by the RPC's transceiver is decoded, stored in a packet buffer and the Host microcontroller signaled that a valid packet is waiting to be uploaded.
