1 INTRODUCTION
1.1 SIMOCO PULSE AIR DATA MODEM
The Simoco Pulse Air Data Modem is one of the Simoco Pulse suite of products, which enable
organisations to deploy Supervisory Control and Data Acquisition (SCADA) telemetry applications
over narrowband Private Mobile Radio (PMR). Using wireless radio infrastructure as the
communications carrier, Simoco’s Pulse solutions enable SCADA applications to be quickly and
cost effectively deployed across large operational areas.
The Simoco Pulse Air Data Modem is a DC powered, standalone unit based on the SDP600 Series
Portables Radio Transceivers that connects to a local Remote Telemetry Unit (RTU) using a serial
port. Distributed Network Protocol 3 (DNP3) control messages are wirelessly transported between
Master and Slave over a PMR system using Digital Mobile Radio (DMR) modulation and Tier III
trunking protocols.
The infrastructure end is comprised of a DMR base station that has an integrated RTU gateway,
which, via a User Datagram Protocol (UDP) Internet Protocol (IP) connection to an IP to Serial
converter, will relay any DNP3 message to and from its connected Master to and from the
applicable Slave RTU unit within the radio coverage of the base station.
