The Serial Adapter /Serial Converter - Generally

A serial adapter, also referred to as a serial converter is a small electronic device which can convert one type of data signal into a different type of data signal. The difference between an adapter and a converter generally is that an adapter usually only adapts the physical interface of a device to match a different type of physical interface of a different device whereas a converter converts the actual data stream between two devices. Therefore we will use the term 'converter' in the following.

A serial converter typically converts data between either RS232, RS485, RS422, USB or TCP signals, however some converter designs have other special conversion features. Even the RS232 standard is an older communication protocol it is still used by many modern devices in both business and consumer markets and is also often used for personal and office devices. Actually many new devices designed today are designed with a RS232 serial port, often because RS232 is a very robust and reliable protocol which is fairly easy for program writes to integrate into their system.

Serial converters are used a lot in industrial applications as a way to communicate with factory machinery or to interface with test equipment, however in one particular area the serial converter has also become very useful for consumers who need a serial port in their personal computer. Most new computers today does not have a RS232 COM port which makes the use of a USB to serial converter useful for connecting equipment such as serial printers, scanners, scales and GPS devices, but also many types of business, office and laboratory equipment. A USB to serial converter typically can convert USB to either RS232, RS485 or RS422 signals.


When you troubleshoot issues with a serial device, there are some quick tests that you can complete to rule out potential problems. You can test to make sure that the following components are working correctly and are not the source of the issue:

  • Serial cables

  • Serial ports

  • Serial devices

To test your setup components, try the following:

  • Use the serial cable, serial port, and serial device in another setup to see if the problem is with the components or the setup.

  • Use a different serial cable, serial port, and serial device in your setup to see if the problem persists. Ideally, you should test a component that you know works in another setup.

When you test the serial ports and serial device, it is recommended that you do the following:

  • Press the Windows key + R, type devmgmt.msc, and press Enter to open Device Manager. Check to see if your device is listed under Ports (COM & LPT).

  • Make sure that the COM port number is the correct number for the serial device and that the software being used to connect the computer to the serial device uses the correct COM port number.

  • If you do not see the COM port number in Device Manager see this FAQ for PCI/PCIe expansion cards: https://www.startech.com/support/faqs/technical-support?topic=expansion-cards#pci-pcie-cannot-boot-os-or-detect-windows
    or this FAQ for USB devices: https://www.startech.com/support/faqs/technical-support?topic=expansion-cards#usb-cannot-detect-windows

  • If the device is listed with an error, follow the instructions on the website to reinstall the drivers.

Note: Some serial devices work only if the COM port number is between a certain range. For example, COM1 to COM4.
