For freestanding signs, wired communication requires trenching the data cable out to the sign site. All data cables should be trenched in 1.5" conduit. The data connection point for the sign is typically within the leg opposite from the power connection.
For Ethernet cables, it is recommended to use an outdoor grade Cat5e or Cat6 cable such as Belden 7919A or Belden 1594A. A maximum length of 330 feet can be used for Ethernet cables, or 900 feet if purchased with extender devices.
For fiber optic cables, the maximum length depends on the media converter purchased with the sign. Consult your sign specifications for maximum cable length.
For most freestanding signs, there is an included Ethernet cable that runs from your LED sign's controller to an access panel on one leg. You will be connecting your trenched Ethernet cable to this cable within the access panel, using moisture resistant connectors.
