We are giving specifications below, why one should consider procuring Cisco 10 Feet Serial Cable Cables features, a general overview, description, performance specification, relevant images, a competitive price infographic, and technical information about the CAB-SS-X21MT model with compatibility.

Design and Construction

The CAB-SS-X21MT is a 10-feet data transfer cable from Cisco, designed to transfer data between X.21 interfaces. Here is an overview of the design and construction of this cable:

  • Connectors: The cable has two connectors on either end, both male, designed to connect to X.21 interfaces. The connectors are made of high-quality materials to ensure durability and longevity.
  • Cable shielding: The cable is shielded to reduce interference and improve the quality of the data transfer. The shielding also helps to protect against electromagnetic interference (EMI) and radio frequency interference (RFI).
  • Cable jacket: The jacket is made of a high-quality, flexible material that is designed to withstand wear and tear. The jacket is also resistant to temperature changes and other environmental factors that can affect the performance of the cable.
  • Cable length: The cable is 10 feet long, which makes it suitable for use in a variety of settings. The length of the cable ensures that it can be used to connect devices that are located some distance apart.
  • Data transfer rate: The cable is capable of transmitting data at high speeds, up to 10 Mbps. This makes it suitable for use in applications where fast data transfer is necessary.

Differences Between

The CAB-SS-X21MT is a Cisco 10-feet data transfer cable that is designed to transfer data between X.21 interfaces. Here are some differences between this cable and other similar cables:

  • Connector type: The CAB-SS-X21MT has two male X.21 connectors on either end of the cable, whereas other cables may have different types of connectors, such as DB-9 or DB-25 connectors.
  • Cable length: The CAB-SS-X21MT is 10 feet long, which makes it suitable for use in a variety of settings. However, other cables may be shorter or longer, depending on the specific needs of the user.
  • Data transfer rate: The CAB-SS-X21MT is capable of transferring data at speeds up to 10 Mbps. However, other cables may have different data transfer rates, depending on their design and construction.
  • Cable shielding: The CAB-SS-X21MT is shielded to reduce interference and improve the quality of the data transfer. However, other cables may not be shielded, which can affect their performance in environments with high levels of electromagnetic interference (EMI) and radio frequency interference (RFI).
  • Cable jacket: The CAB-SS-X21MT has a flexible cable jacket that is designed to withstand wear and tear. Other cables may have different types of jackets, such as PVC or plenum-rated jackets, depending on their intended use.

Troubleshooting Common Issues

The CAB-SS-X21MT is a Cisco data transfer cable used to connect routers, switches, and other network devices with X.21 interfaces. Like any other hardware, this cable may encounter problems that affect its functionality. Some common issues and their troubleshooting methods are as follows:

  • Loose or disconnected connections: Check that the connectors on both ends of the cable are firmly connected. If they are loose, try reinserting them and make sure they click into place.
  • Bent or broken pins: Inspect the connectors and ensure that none of the pins are bent or broken. If you notice any damage, you may need to replace the cable.
  • Faulty cable: If the cable is damaged or worn out, it may not work properly. Try using a different cable to see if the problem is resolved.
  • Compatibility issues: Ensure that the cable is compatible with your network devices. Check the documentation or contact Cisco support to confirm compatibility.
  • Incorrect configuration: Check that the cable is properly configured on both ends. Verify the settings for speed, clocking, and other parameters.
  • Software issues: Sometimes, the problem may not be with the cable itself, but with the software or firmware on your devices. Ensure that your devices are running the latest software and firmware versions.
  • Environmental factors: Electrical interference or other environmental factors can also cause issues with the cable. Try moving the cable to a different location or shielding it from interference sources.

About Refurbished Products

Refurbished products are typically refurbished by an Original Manufacturer or an affiliate of the manufacturer or 3rd party facility. This product may have minor blemishes due to normal product usage and doesn't necessarily come with documentation and software unless indicated, but has been well tested and generally has never had any defects.

Serial cables are mostly used for data transfer between two devices using a serial communication protocol. The type of connectors at the ends of these cables depends on the specific applications. Because of that, there are different types of serial cables in the market. That means you need to pay close attention to the connector type before making any purchase.

What is the Maximum Serial Cable Length?

There is no straightforward answer to this question because there are different factors you have to consider. The first one is the characteristics of your signal transmitter and receiver. Secondly, you have to consider the baud rate and electrical characteristics such as impedance and capacitance. All these factors influence the distance that the signal travels. And if unnecessarily long cables are used, the signal can be lost.

DTE to DCE Serial Cables

The DTE and DCE are acronyms for data terminal equipment and data communication equipment, respectively. The cables have a 9-25 pin connector on one end and a 25-25 pin connector on the other end. They are usually used for interfacing computers and modem cards where the computer is the DTE and the modem card the DCE.

Null-Modem Serial Cables

This involves the use of a null-modem configuration where two DTE devices are connected together. Three main types of null-modem cables exist depending on the pin connectors. You can find 9-9, 9-25, or 25-25 pin connectors. This configuration requires a null-modem adapter.

Other Serial Cable Types

Apart from the serial cables mentioned, there is also another category DCE to Smart Serial and DTE to Smart Serial cables. You can also find an ethernet to USB serial cable for specialized applications. If you need any of these cable types, then you can contact us at ALLHDD. We have up to 10 feet serial cable for your application.
