10.2 Connections & Operation
The two 44-pin HD male D-sub I/O connectors (labeled “GEN I/O A” and
“GEN I/O B” on the front of the Module) provides connection between the
user I/O devices the Control. This port provides 16 source-only outputs
(described in detail in
section 10.2.1 on page 150 ), and 16 sink or source
inputs (described in detail in section 10.2.2 on page 153 ).
