Serial Transition Cables
Cisco does not recommend that you attempt to manufacture your own serial cables (because of the
small size of the pins on the DB-60 serial connector). To order a cable, refer to the section “Obtaining
Service and Support” at the end of this document. To manufacture your own cable, refer to the cable
pinouts provided in the section “Cable, Pinout, and Port Specifications.”
EIA/TIA-232 Connections
The EIA/TIA-232 standard supports unbalanced circuits at signal speeds up to 64 kbps. The serial
port (labeled “SERIAL”) supports synchronous connections. The console and auxiliary ports also
use an EIA/TIA-232 connection; however, the console and auxiliary ports support asynchronous
connections.
The network end of the EIA/TIA-232 serial transition cable (not included) provides a DB-25
connector, as shown in Figure 3. The end that connects to the serial port on the rear panel of the
router has a DB-60 connector. EIA/TIA-232 serial transition cables are available with a DB-25 plug
or receptacle in either DTE or DCE mode. To order a cable, refer to the section “Obtaining Service
and Support.”
