All positions accept an output module. Position eight also accepts an
input module. You can configure the input module (in position 8) to
automatically load scanned bar code data into the match code table.
This function is referred to as Autoload Input. Match code functions
are described in detail in Chapters 7 and 8.
Each decoder has two conduit holes or optional connectors for
wiring the I/O modules.
The I/O Module Board is available in several variations for factory
or customer installation. You can order the decoder with the I/O
Module Board only for customer installation of specific modules, or
with 2 DC outputs and 1 DC input for ”out of the box” applications.
