ADDENDUM: Ethernet Cross Cable Wiring Connection
P/N: 2900 - 9999993 A1
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).
