Medium Range, Lower Cost 2.4 GHz License Free Radio:

	Link PLCs to each other or an HMI computer to your field PLC. Provides a transparent serial connection between two locations.
	Link a master PLC or HMI to remote PLCs.  For poll response protocols, there is no limit to the number of remotes.
	Build a wireless Modbus system across a facility or region.  DIN-S radio is the Host, DIN-R Modbus radios with built in I/O are the slaves.

Build industrial wireless data links between RTUs, PLCs, I/O Expanders, controllers and sensors without cable over distances of up to 10 miles.  Create RTU or PLC based SCADA systems that are networked using wireless serial RS485 data multidrop connections.

Overview
Synetcom's 2.4 GHz Serial SCADA Radio Modem can be used to link SCADA devices such as PLCs.  The radio securely delivers transparent error-free serial data in adverse industrial environments, even with other in band interference (other nearby spread spectrum radios). 

Wireless I/O Application
Simple SCADA systems are easily constructed without PLC and RTU devices by connecting the SCADA Radio Modem to Synetcom's Radio Telemetry I/O Expander (DIN-IOS) module.  The combination creates high I/O count 4-20 mA current loop, discrete and relay connections between sites without cables, PLCs (and associated PLC programming expenses).  As few as one I/O point between a pair of locations can be easily and incrementally expanded to many I/O points between many locations.  Only one SCADA Radio Modem is required at each site.  No programming is required.

Installation
Serial SCADA Radio Modems are always shipped factory-configured and tested. There is no field configuration necessary. Typical installation involves simply mounting and powering the units and connecting the antennas and serial ports.

Frequency Hopping Spread Spectrum
The 2.4 GHz Radio Modem utilizes frequency hopping spread spectrum with advanced protocols that greatly increase the communications reliability in high noise and interference environments.

PLC and RTU Networking
Point to point or point to multipoint communication between Modbus host and field PLC or RTU remotes is supported with one serial Radio Modem at each location.

Repeaters
Radio Modem repeaters are used wherever either distance or major obstructions cause the radio signals to be weak. In large facilities, the repeater is typically located at the highest point so that coverage is obtained everywhere.  The control room only needs radio coverage to the repeater, greatly simplifying installation and guaranteeing low data latency - unlike meshed systems which can have very high latency.  The repeater consists of one or two SCADA Radio modems in a null data connection.  Data is processed through the Repeater in digital form so sensor reading accuracy is never affected.

System Accessories
Synetcom offers a complete line of accessories and system enhancements including:
- Antennas and coaxial cable for short and long distance applications
- Lightning and external surge / loop isolation equipment
- NEMA plastic and metal enclosures with internal DIN rail mounts - designed to house the radio, power supply and other options
- Solar panel, battery, radio enclosure optimized for installations where AC power is not available.

Transmission Range
Synetcom specifies a 10 mile (2.4 GHz 80 mW) range that includes a 20 dB margin (if the signal fades as much as 20 dB - a factor of 1/100 - the link continues to operate).  This assumes line of sight between 18 dBi dish antennas with .6 Fresnel clearance or better.  Obstructions in the line of sight path reduces range, depending on the type of obstruction.  Contact our factory for assistance.
