M-Bus (Meter-Bus)

M-Bus (Meter-Bus) is used for remote reading of heat meters and other consumption meters.

Wrong Baud Rate, polarity, or parity yields decode failure; prefer Auto Detect first. For channel-prefix differences, see Settings.

- Master: Master signal channel and polarity (Auto / Idle High / Idle Low). Default polarity: Idle High.
- Slave: Optional Slave channel and polarity when a Slave is on the bus. Field enabled (Enable) when checked. Default: cleared (channel and polarity field disabled (Disable)); when enabled, polarity Default: Idle Low.
Baud Rate:
- Auto Detect: Auto-detect baud rate; when checked, the Baud Rate list is field disabled (Disable). Default: checked.
- Baud Rate: Manual baud rate. Default: 9600.
