The following lists the minimum requirements so that you can use your Zebra 3S:
A computer running Aurora Design Assistant.
An Ethernet M12-X 8-position to RJ-45 cable that supports Ethernet Cat5e or better, as well as installed and functioning Ethernet drivers.
If not using PoE+, use a Zebra 3S digital I/O and power cable with a connected power supply.
A Zebra 3S digital I/O and power cable, plus a power supply.
Note that, if PoE+ is used to power your Zebra 3S, power comes over the Ethernet (M12-X 8-position to RJ-45) cable, and not over the Zebra 3S digital I/O and power cable.
