Digital I/O Lines
The KUSB-3100 module provides 8 dedicated digital input lines and 8
dedicated digital output lines.
Using DT-Open Layers, you can specify the digital line that you want
to read or write in a single-value digital I/O operation. Refer to
for more information about single-value operations.
A digital line is high if its value is 1; a digital line is low if its value is
0. On power up or reset, a low value (0) is output from each of the
digital output lines.
Note:
You can also read or write to the digital I/O lines using direct
register calls. Refer to
for more information on these
calls.
Resolution
The resolution of the digital ports on the KUSB-3100 module is fixed
at 8-bits.
