Prerequisites Requirements There are no specific requirements for this document. Components Used This document is not restricted to specific software and hardware versions. The information in this document was created from the devices in a specific lab environment. All of the devices used in this document started with a cleared (default) configuration. If your network is live, make sure that you understand the potential impact of any command. Conventions For more information on document conventions, see the Cisco Technical Tips Conventions. EIA/TIA232 Speed and Distance Limitations As with all signaling systems, EIA/TIA232 signals can travel a limited distance at any given bit rate; generally, the slower the data rate, the greater the distance. The table below gives the EIA/TIA232 speed and distance limitations.

2 Data Rate (Baud) Distance (Feet) Serial Cable CAB232MT Distance (Meters) This section presents the cable assembly and pinouts for the CAB232MT serial cable. Note: The cable itself identifies the Cisco router as a data terminal equipment (DTE) or data communications equipment (DCE) device to other devices in the network; for this reason, it is important to select the correct product number from the table below. The cable gender for this product (part number ) is Male Male, mode DTE. The CAB232MT cable is used in the Cisco 7000 family, Cisco 4000 series, Cisco 3600 series, Cisco 2500 series, Cisco 1600 series, Cisco access servers, and AccessPro PC cards. This cable has a male DB60 connector on the Cisco end and a male DB25 connector on the network end.
