1.1	10
3.4	11	Ethernet is used for various devices within a Crestron Lighting Control system, including connecting a lighting control processor to the lighting network, connecting Zūm Net devices to the lighting network, connecting TSW touch-screen interfaces to the lighting network, and connecting the lighting network itself to a building network (building LAN).

3.1	13	== Cabling ==
1.1	14
3.4	15	All cable should be Category 5e or greater (including Category 6 and Category 6a).
1.1	16
3.4	17	The maximum length of any single ethernet run is 100 meters (328 feet). Runs longer than this will require a powered ethernet switch (such as a CEN-SW-POE-5) to be installed midway through the run to enable proper communication.

3.1	19	== Terminations ==
1.1	20
3.2	21	Cresnet Ethernet devices require the use of RJ-45 connectors.
	22
3.4	23	While either T568A or T568B termination pin-out are acceptable as long as they are used consistently, it is recommended to use the T568B pin-out for all terminations. By keeping to one standard, it is easier to stay consistent and prevent errors where the two sides of a single cable are not terminated to the same standard.
3.2	24
	25	See// Figure 1 //for the T568-B pin-out.
3.4	26
	27	When making RJ-45 terminations, take care that the wires are in the correct order and pushed all the way to the end of the connector. A crimping tool with sharp blades that have not been dulled with use also helps in making good terminations.
