Have you had difficulty using a USB to RS-232 adapter to connect your RS-232 device to a computer? If so, you are not alone. Our customers frequently encounter issues with these adapters. In this article, I’ll briefly discuss the origin of these issues and provide you with some suggestions for successfully handling them.
The Evolution from RS-232 to USB In the old days of personal computers, one of the primary connections available was the RS-232 serial port. Apart from the parallel port, it was the primary means to connect an external device.
The connector was reduced from a 25-pin connector to a 9-pin connector, but RS-232 ports remained present on every computer for many years. Built-in RS-232 ports featured direct mapping to memory and worked at a high priority.
Data practically flowed directly to and from the software that was accessing the serial port. Program download muzica. In 1996, the Universal Serial Bus (USB) standard was introduced as a replacement for the serial connector and other connector types that were typically found on the back of computers. The USB provided smaller connectors and more data throughput than the serial and parallel interfaces it replaced.
USB devices have high throughput, but they use a shared data bus. Data is wrapped up and transferred in packets. To handle the packets and move data in and out of the program accessing the USB device, a software driver is needed. The software driver sits between the hardware and the computer program you are using, and it must be installed and working correctly. The Necessity of an Adapter With the widespread adoption of USB, most computers sold now do not have an RS-232 port. Therefore, to connect an RS-232 device (such as a ) to a computer, you need to use a USB to RS-232 adapter, such as the.
While USB to RS-232 adapters perform a necessary function, they do have some limitations. For example, there are three types of problems that you may encounter when using a USB to RS-232 adapter:.
Driver issues. Hardware issues. Performance issues Issue #1: Driver The most common problem that our customers encounter with a USB to RS-232 adapter is getting the proper driver installed.
![]()
The driver must correspond to the chip inside the cable—not to the manufacturer of the cable. For USB to RS-232 chips, there are two primary manufacturers: Prolific and FTDI. Because off-brand chips with poor drivers are unreliable, Campbell Scientific recommends and currently sells a cable using an FTDI chip. We chose this cable because it uses a chip that has a certified driver available on Windows Update.
Serial To Usb Adapter Driver
(The older cables were silver in color and did not have a driver available for Windows beyond version 7.) Tip: Test your USB adapters in the office with your field computer. When you are in the field, your computer won’t have an Internet connection to automatically download and install the driver. If the driver for your adapter is not automatically installed or cannot be installed from a CD, you will need to identify the chip in your cable and locate the driver on the Internet.
Some manufacturers identify on their packaging which chip is used inside their cable. You can also identify a cable’s chip from the Windows Device Manager by following these steps:. In the Windows Device Manager, right-click your device from the list. In the drop-down menu that opens, select Properties. In the Properties dialog box, select the Details tab. In the Property field, select Hardware Ids from the drop-down menu.
In the Value field, there is both a VID (Vendor ID) and a PID (Product ID). These IDs respectively indicate the manufacturer and the model number of the chip. In the example above, I did a quick Internet search for VID 0403 PID 6011, which revealed to me that the chip is an FT4232 manufactured by FTDI. After you know your chip type and manufacturer, you can locate and download the correct driver for your version of Windows. Issue #2: Hardware USB to RS-232 adapters are commodity pieces of computer equipment.
As much as we all wish that everything was as reliable as the CR1000, all adapter cables eventually fail. Although there are two primary companies that manufacture USB to RS-232 adapter chips, there are many cable manufacturers who offer varying levels of cable quality. Higher-quality, industrial models should last longer, but they wear out over time—just like any field tool. A poorly constructed cable could have components that fail in a short period of time—perhaps even by the time you receive the cable. I have seen several cases where old cables could no longer handle 115200 baud, but the cables still worked on low baud rates.
There have been many more cases where a USB cable stopped working half-way through a day in the field. Tip: If your field site is far from your office, take two USB to RS-232 cables with you. Lost time in the field can be a lot more costly than the purchase price of a second cable. Issue #3: Performance As mentioned previously, USB uses a shared data bus with packetized communication.
The packetized communication introduced some latency (data transfer time) that wasn’t present with built-in RS-232 ports. Unfortunately, latency makes a noticeable difference when you download large amounts of data or upload a new operating system. The driver for FTDI chips allows you to lower the latency time on packets.
To do this, you can use the Latency Timer field, which is accessed through the Windows Device Manager. Follow these steps:. From the Windows Device Manager, right-click your device from the list. In the drop-down menu that opens, select Properties. Click the Port Settings tab. Click the Advanced button. In the Advanced Settings window, navigate to the Latency Timer field, and reduce the setting to 1 for best performance.
In addition to lowering your latency time, I also recommend disabling the Selective Suspend option for your cable. The Selective Suspend option allows Windows to put your hardware to sleep, which can result in corrupt data packets.
To disable the Selective Suspend option, clear the checkbox for the Enable Selective Suspend field on the Advanced Settings window for your device. Note: The Selective Suspend option is already disabled by default in the FTDI driver. Conclusion Newer datalogger designs, such as the, feature a native USB connection. Many devices, however, will feature RS-232 connections for years to come, and we’ll need to continue using USB to RS-232 adapter cables. I hope the suggestions I’ve provided help.

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 your cables, it is recommended that you do the following:.
Test each cable individually. Use short cables when you are testing. 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: or this FAQ for USB devices:. 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. Perform a serial loopback test. See this FAQ on how to perform a RS-232 serial loopback test. To check whether or not an RS-232 serial port is working, perform an RS-232 loopback test by doing the following:. If your serial port is not female, convert it by taking a female/female cable or gender changer and plugging it into the serial port.
Take a metal paperclip or wire and cross pins 2 and 3. If you look closely at the female end, the pins should be numbered. Open a telnet session on the COM port number of the device that you are testing. To find out the COM port number, refer to the following FAQ:. Note: To open a telnet session on the COM port, you need a telnet client like PuTTY or Hyper Terminal. Windows XP comes with Hyper Terminal. When the session is open, anything you type into it you should see.
The loopback test fails when you cannot see what you are typing. If the loopback test fails, make sure that the serial cable or gender changer that you are using works and that the adapter is in the correct port. You can check multiple ports at the same time by opening multiple sessions, putting the loopback adapter on one port, and trying to type into each session. When you can see what you are typing, you know that the COM port is working and you can see which port number the physical serial port is.
Close the window for the port that you just tested to speed up the testing of the remaining serial ports. For products related to this article, click.
