3.14 Digital I/O (CN2)
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 ROCKY-512.
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 that can
be selected in BIOS SETUP Menu. You can read or write data to the
selected address to enable the function of digital IO.
