The module combines a UHF `radio transceiver and a 64kbps packet controller.
• • • • • • • • • • • • Crystal controlled PLL FM circuitry for both Tx and Rx Reliable 75 meter in-building range, 300m open ground Built-in self-test / diagnostics / status LED’s Complies with ETSI EN 300 220-3 Complies with ETSI EN 301 489-3 Single 5V supply @ < 27mA 64kbps half duplex Free format packets of 1 - 27 bytes Packet framing and error checking are user transparent Collision avoidance (listen before transmit) Direct interface to 5V CMOS logic Power save mode The RPC2A-module INTRODUCTION The RPC2A is an enhanced replacement for original RPC-433-40 transceiver.
It is a self-contained plugon 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 RPC2A's packet buffer is transmitted by the RPC2A’s transceiver and will "appear" in the receive buffer of all the RPC2A's within radio range.
A data packet received by the RPC2A’s transceiver is decoded, stored in a packet buffer and the Host microcontroller signalled that a valid packet is waiting to be uploaded.
