Lon is a data standard used largely by ETC Architectural products to carry data and power to architectural outstations such as button stations, occupancy sensors and daylight sensors.
Lon is assigned different names depending on the system it is being used with:
- Paradigm and Legacy Unison: LinkPower
- Echo: EchoConnect
- SmartLink: LinkConnect
It is important to note that although the cabling is the same for all of these systems, the data carried is not the same - for example, connecting a Smartlink station to a Paradigm processor will not work!
The voltage requirements also vary depending on the system:
- Paradigm and Legacy Unison: 42vdc
- Echo: 24vdc
- SmartLink: 42vdc
- Note: AUX voltage for all systems is 24vdc
Lon is a topology free cabling system, meaning that the cable can be split, starred, daisy chained or any combination of these. The only restriction is that the total length of cabling must not exceed 1640' (500m) without use of a repeater.
ETC recommends the use of Belden 8471 cable for Lon systems. It is very important to note that DMX cable, Cat5 cable and other types will not work for Paradigm and legacy Unison. It is possible to use Cat5e cable in Echo, but it will limit your bus length to 1000 ft. (304.8m).
ETC has compiled a cable cross database that includes tested possible substitutes and whether or not they are approved. If you want to use a cable that is not on that list, it will need to be checked and approved by our Applications Engineering team.
