I/O Wiring and
Specifications
Since there are only 32 LEDs on the module, you
can only display the status for 32 points at one
time. In the A - B position the status of the first
group of 32 input points (A0--A17, B0--B17) are
displayed (connector 1). In the C - D position the
status of the second group of 32 input points
(C0--C17, D0--D17) are displayed (connector 2).
