Wiring the Digital Inputs
The digital inputs are arranged in two isolated groups:
 I0-I9 share common CM0
 I10-I13 share common CM1
Each group may be wired together as sink or source.
Inputs I10, I11, I12 and I13 can be configured as either normal digital inputs or as high
speed inputs that can receive high speed pulse signals from sensors or shaft encoders.
High Speed Input Modes
Following are the different pin assignments for the high speed channels:
Channel 1
