The products from the ARM Advanced Radio Modem® range use the ISM (Industrie Scientifique Médical) bands and can be used freely (free without any licence) for industrial, scientific and medical applications. This band is a good balance between range, power, and antenna size between 863MHz and 870MHz.
The ARM-SE, ARM-X, ARM-D/DA products are designed for industrial usage. Placed in an electric cabinet on a DIN rail, they adapt perfectly to all sorts of products connected in RS232 and RS485 serial ports, Ethernet or to report digital or analog I/O. With the maximum power (500mW/27dBm) the range can be up to 5 km line of sight.
Serial / Ethernet radio modem
The Ethernet ARM-SE (Advanced Radio Modem Serial + Ethernet) radio modem offers an interesting alternative to wifi. It is well adapted to a wireless connection with a long distance disrupted environment.

Digital radio modem
The ARM-D and ARM-DA radio modems are well adapted for application including a report of digital or analog states : telecontrol, supervision, monitoring, alarms.
They work in”mirror” mode (Input-output transfer in both ways, in cyclic or detection mode) or in “Modbus slave” mode, accessible in this case from a Modbus/TCP ou Modbus/RTU master, by going through an ARM-SE radio modem.
- Display panel Synchronization
- PLC state report
- Analog 4-20mA or 0-10V report
- Cranes, industrial conveyors
- Pumping station, valve control
