NI wireless sensor network (WSN) measurement nodes are shipped with a built-in, 2-position MINI-COMBICON power connector and an 18-position, side-entry, screw-terminal I/O connector. The NI WSN-3284 kit contains four extra 18-position screw-terminal connectors and labels, including two top-entry connectors and two side-entry connectors. You also can obtain four extra 2-position power connectors to use with NI WSN Ethernet gateways or measurement nodes.
In addition, NI offers a power connector backshell kit that contains a strain relief attachment for the 2-position power connector on the Ethernet gateway and measurement nodes. This attachment clips on the MINI-COMBICON connector and includes a zip tie to hold the power cable in place.
