The Ultimate Guide to Serial Cables: Connectors, Specifications, and Applications
Introduction to Serial Cables
Serial cables, commonly referred to as DB9 serial cables, RS-232 serial cables, or simply serial port cables, are essential components for connecting various peripheral devices to computers or switch boxes. These cables are designed to facilitate data transmission between devices using the RS-232 serial communication protocol. With their versatile applications, serial cables remain a crucial part of many setups, even in today's digital age.
Common Connectors and Configurations
Serial cables typically feature two types of connectors: DB9 male and DB9 female. The most common configurations include:
- DB9 Male to Male: Used to connect a peripheral device directly to a computer or switch box.
- DB9 Male to Female: Ideal for extending the length of an existing DB9 serial cable, providing more flexibility and reach.

What is a serial cable used for?
A serial cable is a cable used to transfer information between two devices using a serial communication protocol. The form of connectors depends on the particular serial port used. A cable wired for connecting two DTEs directly is known as a null modem cable. Serial cables are typically used for RS-232 communication.
How long can you run a serial cable?
Serial (RS-232) – The maximum cable length that we suggest is 50 feet. At lengths greater than 50 feet, there may be a loss in signal integrity which may affect data.
Are serial cables still used today?
Serial ports might be slow and not much use to most computer users these days, but thanks to their simplicity and reliability these ports may be with us for a long time yet. While the parallel port is now safely buried in the grave of obsolescence, it may seem odd that the humble, slow serial port is still around. Many industrial, scientific, and telecommunications applications continue to rely on serial cables for their reliability.
Are RS-232 cables still used?
Although RS-232 had been replaced by universal serial bus (USB), Ethernet and wireless technologies for connecting peripheral devices, such as modems, printers and mice, to computers, it remains in use in many industrial, scientific and telecommunications applications because of its reliability.
What is the difference between VGA and serial cable?
VGA ports (Video Graphic Array connectors) connect the monitor to a computer's video card. VGA ports have 15 holes and are similar in appearance to serial port connectors. However, VGA ports have holes, while serial port connectors have pins.
