GIA6300 Interfaces
5.1
I/O Data Concentration and Computation (provided by Main Boards)
Table XXX lists the interfaces provided by Main A and Main B in the GIA 6300. Main A and Main B in the
GIA6300 function as two independent units, and interfaces to specific units should not be split across
the boards if practical. Additionally, where practical, primary and secondary sensors should be split
between the two boards so that one board does not directly connect to both the primary and secondary
sensor for given data.

Active Low/High Discrete Inputs and Outputs
The GIA 6300 has configurable discrete I/O in order to use the pins on the external connector more
efficiently. Each discrete interface, input and output, is configurable between either active high or low.
