Kramer Electronics FC-1ETHN user manual Addendum Ethernet Cross Cable Wiring Connection

ADDENDUM: Ethernet Cross Cable Wiring Connection

This addendum describes the correct wiring for crossover cable connections and replaces the opening paragraph in the "Connecting the ETHERNET Port directly to a PC (Crossover Cable)" section in the User Manual as follows:

Connecting the ETHERNET Port directly to a PC (Crossover Cable)

You can connect the Ethernet port of the machine to the Ethernet port on your PC, via a crossover cable with RJ-45 connectors.

Table 1 and Figure 1 define the color codes for the two existing standard types of cross cables used in the industry. Table 2 defines how to connect the wires to the connectors on both ends of the cable.

When manually connecting the ends of a cable, both connectors must follow the same standard (either EIA /TIA 568A or EIA /TIA 568B).
