2.1.10 Digital I/O Ports
The CR200(X) has 2 digital I/O ports selectable, under program control, as
binary inputs or control outputs. These are multi-function ports including:
device driven interrupts, switch closure pulse counting, high frequency pulse
counting, and SDI-12 communications.
FIGURE. Control and Monitoring with
Digital I/O
(p. 9), illustrates a simple application wherein a port is used to
control a device while a second port monitors the state of the device.
