The Wireless M-Bus module "Ready to use / RTU" version is a gateway radio with a standard configuration that allows the immediate implementation of a W-MBus solution.

Pre-certified and compliant with EN13757-4: 2005 standards, the Wireless M-Bus modules embed a complete M-Bus stack.
For the S, T and R operating modes, the user has the choice of 1-12 channel transmitters for flows or throughputs ranging from 4.5 to 100kbps. Data security is ensured by a AES128 encryption system , guaranteeing highly secure data transfers over a distance of 1,000m.
