No The 1756-CP3 cable attaches the controller directly to the controller.
If you make your own cable, it must be shielded, and the shields must be tied to the metal shell (that surrounds the pins) on both
ends of the cable.
You can also use a 1747-CP3 cable from the SLC product family. This cable has a taller right-angle connector housing than that of

Yes The 1761-CBL-AP00 cable (right-angle connector to controller) or the 1761-CBL-PM02 cable (straight connector to the controller)
attaches the controller to port 2 on the 1761-NET-AIC isolator. The mini-DIN connector is not commercially available, so you
cannot make this cable.
