3.8 HIM Details and Interface Types
List of HIMs with
hardware details and
interfaces
A complete list of HIMs and the interface types associated with each HIM is
shown in the table below:
Note: The maximum number of devices supported by the connection between
the DMB port on the CPU board and the DMB module(s) is 16.
Note: The maximum number of devices supported by the connection between
the DSB port on the CPU board and the DSB module(s) is dependent on
the protocol (see Devices/Port in the Protocols and HIMs tables).
Note: The hardware configuration of dispensers with multi-point fuelling
points affect the number of HIM connections required by the fuelling
point. See ‘Hardware configurations and interface connectivity’ on
page 33.
