Appendix A.3. M-Bus Connection R2 Port

The M-Bus driver allows the FieldServer to transfer data to and from devices using M-Bus protocol. The
Fieldbus connection is included with the FieldServer. The M-Bus QuickServer Gateway is configurable to
act as both a Master and a Slave M-Bus device.
The M-Bus Connector consist of a + and – terminal. Most M-Bus Devices are not polarity sensitive,
although the polarity of the M-Bus Connector is indicated on the device diagram, should it be a
requirement. The M-Bus devices communicating with the FieldServer must be configured according to the
manufacturer's instructions (e.g. primary address and readout data).
The following baud rates are supported on the R2 Port:
300, 600, 1200, 2400, 4800, 9600, 19200, 38400

Appendix A.4. Enhanced Network Security
