The IntelliLogger model IL-80, IL-90 and IL-20 have active BBus connectors and additional
Interface Modules can be connected to increase the input/output capability.

ABLING
The BBus interconnecting cable starts at the System Base BBus connector (Figure 3-1) and
daisy chains to up to a total of 16 BBus modules. Each Interface Module has two BBus
connectors at the bottom end (Figure 3-2). For systems with multiple expansion modules, the
cable runs into one then out of the other and on to the next module.

CAT5 or better cable should be used for BBus connections. This cable is the same cable
used for Ethernet based networks and is readily available from most computer stores as well
as from Logic Beach.
The last module in IntelliLogger deployments with long BBus runs should have a BBus
terminator stub plugged into the second BBus connector. This terminator serves to minimize
signal distortion.

Each module that is connected onto the BBus must have a unique Address such that all
modules will be uniquely identified. The address is defined by configuration of the Module
BBus Address DIP switch (Figure 3-3) which is accessible at the top end of the module. 16
unique addresses can be set by the combination of the 4 switches integral in the DIP Address
switch.
As shown in Figure 3-3, all switches in the OFF position indicates an address of 00 and all
switches ON sets the address to 15. The actual address used is not critical, just ensure that
each module on the BBus has a unique address.
Note
: Interface Modules packaged within an IL-80 or IL-90 System Base
always have an address of ’00.’ This address cannot be changed. Insure
all external Interface Modules installed on the BBus network are set to
addresses other than 00.
