3.10 Multi-Functional output pin: DO/CMP
The PCI-8158 provides 8 multi-functional output channels: DO/
CMP0 to DO/CMP7 corresponds to 8 axes. Each of the output
pins can be configured as Digit Output (DO) or as Comparison
Output (CMP) individually. When configured as a Comparison Out-
put pin, the pin will generate a pulse signal when the encoder
counter matches a pre-set value set by the user.
The multi-functional channels are located on P1 and P2. The sig-
nal names, pin numbers, and axis numbers are shown below:
