FEATURES

The RPC3G 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 RPC3G's packet buffer is

transmitted by the RPC3G’s transceiver and will "appear" in the receive buffer of all the RPC3G's within

radio range.

A data packet received by the RPC3G’s transceiver is decoded, stored in a packet buffer and the Host

microcontroller signalled that a valid packet is waiting to be uploaded.

RF specifications are provided on BiM3G-869-64, BiM3G-914-64 RF transceiver datasheet.

The RPC3G is an intelligent transceiver

modules, which enable a radio network/link

to

implemented

between

a

number of digital devices. The module

combines a BiM3G UHF RF transceiver and

a 64kbps packet controller.
