Separate decoders provided inputs outputs. permit system expansion, eight 5B08-MUX backplanes daisy-chained system ribbon cable total channels. Jumpers each backplane (labeled J1-J9 J10-J18) determine block eight addresses assigned each backplane. Input (read) output (write) addressing completely independent; cases, Jumpers J1-J9 control inputs J10-J18 control outputs. Independent addressing might used, example, update output modules without interrupting monitoring input modules.

Series modules meet transient voltage protection standard ANSI/IEEE C37.90.1-1989. Series modules prevent damage connected system even when very large, fast transient strikes eight field lines same time. However, proper grounding backplane essential ensure full protection since, such cases, currents order ampere, with rise times order microsecond, must delivered ground. Both resistance inductance ground path critical. applications where hazards this magnitude exist, large (#10-32) ground stud provided each 5B08 backplane 5B08-MUX backplane) should connected system ground shortest practical length large diameter wire. surge withstand capability tested with less than fifty bursts second. test duration seconds widely accepted. rise time kV/µs specified each module could surge current order ampere.
