10 Appendix - Digital I/O (Pin Assignment)

The two digital I/O ports provide two digital inputs and two relay outputs that can be used
to exchange digital signals with external devices. The port numbering on the rear panel
corresponds to the numbering of the relays and digital inputs in Chromeleon.

To connect an external device to the digital I/O ports on the rear panel, use the appropriate
mini-DIN cable (part no. 6000.1004). The table lists the functions assigned to the
connector pins and the color and label of the cable wire connected to each pin.
