3.16 Digital I/O (CN27)
One characteristic of digital circuit is its fast response to
high or low signal. This kind of response is highly needed
for harsh and critical industrial operating environment.
That’s why we design 4-bit digital inputs and 4-bit digital
outputs on the JUKI-511P.
Digital Input and Output, generally, are control signals.
You can use these signals to control external devices that
needs On/Off circuit or TTL devices. The register address
is 240H, 260H or 280H, which is selected in BIOS SETUP.
You can read or write data to the selected address to
enable the function of digital IO.
