General Purpose Input/Output Port

The CP-RIO3-05 module provides one general purpose input/output port with five general pur-
pose inputs and three general purpose outputs. The GPIO port is implemented as a 10-pin on-
board connector J10.

The following figure and table provide pinout information for the onboard GPIO connector J10.

Note ...

The GPI signals tolerate only 3.3 V signaling and the inputs have internal pull-
up resistors.

The GPI and GPO signals support LVTTL signaling.
