M-Bus (if fitted)
After power-up, the unit defaults to the baud rate and primary address set in the M-Bus Menu (see
page 25). Both the baud rate and primary address may be changed later over the M-Bus network.
The secondary address is the unit serial number padded with two zeros.
Characters are configured as 8 data bits, 1 parity even bit and 1 stop bit, and the following bit rates
are supported: 300, 2400 and 9600 baud.
The U1000 MKII will only respond to M-Bus requests while operational, while the flow reading,
volume total, energy total, power or temperature screens are displayed.
The M-Bus module supports the following functions:
•
Acknowledge Function

Slave Select Function
