Data Radio Modems are Great Tools for SCADA and Telemetry Systems.
Use Raveon’s RV wireless data modems for SCADA and Telemetry systems. Use all your own devices, your Controller, your Slave Devices, on your system. Wireless Modems extend the range and increase the reliability.
Use Wireless Slave Devices
To save costs and make the system easier to install and move, Raveon provides “Wireless Slave Devices”. A wireless slave device has general purpose IO connections on it, with a built in radio modem, and secure and reliable communication protocols. Use SCADA commands or MODBUS commands to communicate with Raveon’s wireless slave devices. Raveon’s Tech Series radio modems have a myriad of IO options and frequency band options, to work as wireless slave devices for Remote Terminal Units (RTUs)
The Tech Series Remote terminal Unit (RTU) modem:
GPIO Interface Options: (Configurable)
- Switched DC Power output
- Analog Inputs to measure voltage
- Open Drain Switched output driver
- Digital Input for data bits or switch status.
Raveon’s Unique Features for SCADA Applications
- Long Range. Coverage typically covers 10-100 square miles ( 16 to 160 square kilometers).
- Remote status monitoring including DC voltage, packet error statistics, modem “up time”, and receiver signal strength.
- RS-232, RS422, RS485, USB, GPIO, and ANALOG. RS232 is standard, and a myriad of other interfaces are available.
- Very fast Transmit-to-Receive turn around. 3mS attack time enables very fast polling in your wireless telemetry system.
- Easy to use. Plug-in, Turn-on, and GO. Transmit data in = Receive data out.
- Usable for Telemetry Communications. All radio modems support serial comm protocols such as MODBUS, DNP3, and many others.
- Built in protocols. Some Raveon data radios have telemetry protocols built into them, such as MODBUS.
- Secure Data. All Raveon data radio modems have built in AES encryption.
- Low Cost. Raveon’s wireless data modems are the most economical data radio modems on the market. And there are no cellular fees on private radio networks.
- Remote “PING” From any modem, a user may send a “PING” to any other radio modem to find out the link signal strength. This allows quick diagnostics, easy antenna alignment, and reduced site visits.
- Lowest current draw in industry. Most Raveon wireless modems draw less than 90mA when fully operational, and some are less than 80mA.
- Wide input voltage with high-efficiency switching voltage regulator.
- Packetized AND Streaming Data. Integrated Packetized data protocol with error correction and built-in Streaming Real-Time operation. User selectable.
- Capable of store-and-forward repeating operation.
- Small size. Extruded aluminum enclosure is small, and very rugged.
- 16 bit addressing for up to 65,525 different unique device addresses per channel. Radio channels may be shared with no interference between users.
- Supports group and broadcast transmissions. Network mask allows groups of any size.
- Easily to configure. Modems are configured using “AT” commands through the modem’s serial port or by using Raveon’s Windows-based Radio Manager configuration program. There is no need for a separate serial link to the modem to configure or manage it.
- RS-232 serial input and output. Programmable serial baud rates up to 115400 make the FireLine compatible with most every PLC, PC, and HMI device made.
- Programmable over-the-air data rates. YOU can choose how your system will work. Set the OTA data slower for extended communication range, or set it fast for lowest latency. Your choice.
Other Raveon SCADA and Telemetry Technology
SCADAcomm: The SCADAcomm software app is a free open source tool for experimenting and using MODBUS messages to communicate with slave devices that utilize MODBUS messages such as Raveon’s GPIO and FIO slaves. See AN230(ModbusMx) for information about MODBUS.
Serial IO. Raveon modems have many serial IO options. For more information about the pros and conns of various serial communicatoin methods such as RS232, RS484, RS422, USB, and Ethernet see Application Note AN236.
M7s Series Wireless Modems
Ideal for SCADA and Telemetry applications, the M7 series of products features: 1/2-5 watts of RF output in the 450-480MHz (other bands available), range of 5-50 miles, ultra-fast T-R switching time of 3mS, store-and-forward repeater capability, remote “Ping” capability, voltage, temperature, and current monitoring, and RS232/422/485 interfaces available. Perfect for SCADA, remote control, telemetry, mobile-data, and AVL applications.
Tech Series Wireless Radios
Raveon’s Tech Series M21 radios have Range capabilities of up to 50 miles for GPS tracking, data communications and SCADA. The M21 also has an even faster turn around time then the M7, and an interchangeable front I/O panel. The M21 has a new power connector that is rugged and water sealed.
Built into this product are SCADA and Telemetry commends to control and read the IO pins. A MODBUS option is available so MOSBUS protocol can be used to manage the GPIO interface and IO pins on other interfaces.
Tech Series IO connectors:
- RS-232 (DB9 Computer UART port)
- RS-422 ( Differential IO with Screw Terminals)
- RS-485 ( Differential IO with Screw Terminals)
- USB ( USB interface with Serial Converter)
- GPIO (General Purpose IO, Screw Terminals)
- Analog (DB15, Analog and RS232 serial)
Daisy Chain your network with wireless data links. Raveon’s “Daisy” modem comes as either a cellular modem, or a FCC licensed radio modem on either UHF or VHF bands. The Daisy modem is Raveon’s most compact design yet, small enough you could even use this on most drones with little to no affect on the drone itself. The Daisy modem is perfect for linking together multiple devices that would otherwise need to be wired together.
