Configuring the optional RS-232C/Ethernet
Converter
The optional RS-232C to Ethernet Converter provides a standard RJ-45
connection. Refer to Figure 3–6 for an illustration of a RJ-45 connector and pin
identification. Cable pin-outs for standard and crossover cables are listed in
Table 3–5 and Table 3–6, respectively. For additional information about the
configuration and use of the RS-232C to Ethernet converter, refer to “Ethernet
Serial Server” on page 5-1.
