Caution: Shielded Cable Requirement
Shielded Cable is required for ALL LQ SERIES GPIO Port connectivity. Shielded Cable must be used to assure compliance with domestic and international emissions standards. Customers, Installers and or qualified Personnel failing to use shielded cables may cause radio interference in which case the user may be required to take adequate measures.
