6. Communication

The counter supports two communication channels (wireless or M-Bus).
The protocols can be different for each of the two communication channels and are pre-adjusted in the factory.

6.1 Wireless communication

The integrated wireless function is an interface for communication with wireless receivers.
The unidirectional communication is specified as:
• Send every 8 ... 256 s (variable according to max. 0.1% duty cycle (min. 8 s); depending on the protocol
length and programming)
• The communication always transmits the current measured data
• Transmission frequency: 868 MHz
• Various receivers are available to receive the protocol (e.g. Bluetooth, GPRS, LAN, etc.)
• The protocol is OMS Profile A or Profile B and is encrypted
• Reading technology: Stationary or mobile

6.2 M-Bus communication module

Communication with M-Bus is a serial interface for communication with external devices (M-Bus central controller),
e.g. Rossweiner data collector. Several meters can be connected to one central controller.
• The connection is polarity independent and galvanically separated
• M-Bus protocol in accordance with EN 1434;
• 300 or 2400 Baud (auto Baud detect)
• Connection option: 2 x 2.5 mm²;
• Current consumption: One M-Bus load
