Selecting the CPU Board and Interface Modules
9. You are now ready to connect the selected HIMs to the CPU Board.
The figure below shows the devices connected to a CPB539 board through
the HIMs and the associated serial interface cables.
Note: This illustrates that only 16 devices using the Current Loop interface
can be connected to a single port (2 of the DSB492 HIMs are daisy
chained together and connected to a single port). Under normal cir-
cumstances, we recommend that load balancing is used on the ports
when connecting multiple devices (with the same protocol) to mul-
tiple modules – this increases performance.
