  • Page 18: Special Features Of M-Bus Master Multiport 250D

    M-Bus Master MultiPort 250D has been designed with the newest cable driver technology, and is, therefore, rather insensitive to the capacity of the M-Bus network. Thus, designing an M-Bus network to be used together with M-Bus Master MultiPort 250D, the limiting factor as to possible cable length will primarily be the cable resistance in the network.

  • Page 19: Cable

    M-Bus Master MultiPort 250D 4.3.1 Cable The cable resistance and capacity must be as low as possible. The thicker the cable, the lower the resistance. The thicker the cable, the higher the capacity. An M-Bus cable must as a minimum be able to handle 50 V and 500 mA.

  • Page 24: M-Bus Addressing

    5.2 Secondary addressing (00000001-99999999) Secondary addressing uses the last 8 digits of the meter number as M-Bus ID. Kamstrup MULTICAL® meters use the customer number as their secondary addresses, which makes it possible to change the secondary address. Enhanced secondary addressing (00000001-99999999)/(00000001-99999999) The meter’s serial number is used for enhanced secondary addressing.
