2 / 15 page Radiometrix Ltd. UHF FM Radio Packet Modem page 2 INTRODUCTION The RPM3 is a self-contained Radio Packet Modem module that requires only a simple antenna, 5V supply and a serial I/O port on a host microcontroller or PC. The module provides all the RF circuits and processor intensive low level packet formatting and packet recovery functions required to inter-connect any number of devices with serial port in a radio network. A continuous stream of serial data downloaded by a Host microcontroller into the RPM3 serial receive buffer is transmitted by the RPM3’S transceiver and will "appear" in the serial buffer of the addressed RPM3 within radio range. Figure 2: Point to point wireless link with RPM3 + Host microcontroller 1. FUNCTIONAL DESCRIPTION The RPM3 is a connection oriented modem module for sending and receiving serial data via an RF communications link. The RPM3 handles all necessary protocol related functions of validation and retries to ensure error free and uninterrupted data is sent over the communications link. All data transfers between a pair of RPMS are fully acknowledged, thus preventing the loss of data. Bit coding and checksums are used on the data packets to ensure the validity of the received data at the remote end. Figure 3: RPM3 block diagram |
