Simplex 565-413 — wired network media card, the service part number behind sales number 4100-6056.A Simplex 4100 family panel joins a network through the 4100-6014 Network Interface Card, which carries no transceiver of its own. The media card supplies one. This is the copper version: it drives twisted pair between panels point to point, so one wire fault does not bring the network down.
