Tank Cable 4 digital (part number 031858) has originally been designed for the Jayco caravans to screw into the brass threaded connection molded into the side of the water tanks. The 4 digital wiring would then plug into the Tank Cable (3m, 9m length options). The Tank Cable then plugs into the Jcontrol or Control Node for the Jhub systems.
Tank Cable 4 digital 031858 can also be used with monitors such as Trek series and RVView2, as well as with the OdysseyLink / ControlNode, connecting through the Tank Cable series.
