The GB2â¢ system uses simple 2-conductor non-polarized wiring making it ideal for new installations as well as for retrofit applications. All audio, video and data functions are fully digital and using the RAP-2150 cable you can run up to 300 meters from the entrance panel to the furthest monitor.
For CAT5 Cabling, the 4 solid color wires must be joined together as one, and the 4 striped wires must also be joined together as one to create your 2-wire cabling structure.
