Frequently Asked Questions (FAQs)

1. Are all USB to serial cables the same?

A standard port connection uses a DB-9 pin male or female serial connector. Other industrial type USB serial adapters may use an RJ-45 connector for data signal communication. You'll also need to look at your USB port; newer computers can contain a USB Type-C port for a host connection.

2. What cable is used for serial port?

What kind of cable do I need for a serial port connection between two computers? For the type of connection we are talking about here, you need a so called 'null modem cable'. A null modem cable is an RS-232 serial cable where the transmit and receive lines are crosslinked.

3. What is a serial to USB cable?

The U209-000-R USB-to-Serial Adapter Cable allows you to connect a 9-pin RS-232 serial device to a computer or laptop with a USB Type-A port. It works with modems, digital cameras, PDAs, ISDN terminals and other devices with a serial port.

4. How many types of serial cables are there?

The RS-232 specification defines two types of serial devices, DTE and DCE. DTE normally refers to the serial port on a PC or terminal, while DCE refers to a modem or other type of communications device.
