About
Before you connect a device to the router serial port, you need to know the following:
• Type of device, data terminal equipment (DTE) or data communications equipment (DCE), you are
connecting to the synchronous serial interface
• Type of connector, male or female, required to connect to the device
• Signaling standard required by the device
Connecting
• You must provide or purchase separately the correct serial cable. The cable does not ship with the
router. Contact your Cisco reseller to purchase the correct cable from Cisco.
• The router RS232 interface operates as a DCE; any connection to this interface must be as a DTE.
• If you use a DB-9 connector for the serial ports, you must provide an adapter.
• You can connect a device to this port while the router is operating normally.
• The serial ports are labeled SER 1/1 and SER 1/2.
• When connecting the serial ports to devices, you must use cable glands and thread cables through
the chassis cable ports on the router. See the “External Connections and Chassis Cable Ports” section
on page 6-12 for more information.
