All versions are based on shielded twisted pair cabling and connection hardware, providing the highest level of immunity from EMI.
The heart of this system is a shielded patch panel and grounding hardware. The MICROS IDN to Ethernet patch cables, shielded faceplates, modular connectors, and patch cables, all of the same cable category, are also required at each printer location. The shielded modular connectors and patch panel connectors differ from their non-shielded counterparts by providing a method of terminating the drain wire.
