Raveon’s data radio products are well-suited for wireless SCADA and telemetry. Wireless SCADA systems are common for telemetry, remote control, and power grid management. VHF and UHF radio frequencies over very long range communication ability, and with the fastest transmit / receive hundreds of thousands of meters and may be polled or report-in every day on a single radio channel.
Wireless SCADA and Telemetry use radio modems to connect The Master Controller to the Slave Device.
Keep efficient and save costs, and make easier to install and update. A wireless modem with built-in Slave Device such as Raveon’s RV-M21 Tech Series telemetry modems can do.
Raveon Builds Many Wireless SCADA RTUs and Data Radios.
The RV-M21 RTU with the GPIO interface:
A M21 smart radio modem is a innovative Wireless Remote Terminal Unit (RTU)

SCADA Software
Raveon has a free open-source software app for testing and working with SCADA, Telemetry, and MODBUS products. It is called SCADA Comm User (SCU)
This SCU program is designed and built for experimenting and testing MODBUS devices such as Raveon’s Tech Series GPIO and FIO wireless RTUs.
If you would like to work with the source code, it is open to Raveon’s SCADA users, so please contact Raveon sales department.
Wireless RTU
The Tech Series has a GPIO version of the RV-M21 and RV-M22 series radio modems. They are ideal for SCADA and telemetry.
You can use MODBUS messages to control and rad these GPIO pins. (digital inputs, analog input, switched voltage output, and open drain MOSFET relay driver).
The GPIO connector on the product is a Phoenix Contact 1829387 DFK-MC type connector. 3.5mm spacing.
Wireless technologies is a cost-effective way to provide remote and localized control and transfer of live and historical data.
Implementing a wireless infrastructure is beneficial to new production sites.
It drastically reduces installation cost and time, reduce permit costs, and eliminates wiring, trenching, and running conduit. It minimizes wire failure due to degradation and other environmental factors.
Raveon data radio modems can also be used to MIMIC input to another wirleess modem’s output over many miles.
The MIMIC feature can MIMIC input to output over many miles. The change in the Master modem sends automatically to the remote Slave’s outpu.
The Slave send back an ACK to the Master so the LED on the Master shows the status of the remote Slave.
