Connecting to a Distribution Panel
By using two types of octopus cable, you can connect RJ-45 serial ports to a distribution panel
that has DB-25 connectors. This enables you to adapt RJ-45 cabling to Xyplex Telco-style
cabling. Xyplex offers octopus cables that fan out a 50-pin Telco connector to eight male or
female DB-25 connectors. These cables are available in 3', 6', 10', 25' and 50' lengths. You
can connect the unit to the distribution panel via the two octopus cables as shown in Figure 3-9.
(You might need an extension cable to connect the two cables.)
