Product F.A.Q.

Still need help? Reach out!

Do these adapters require an external power supply?
Most of our single and dual-port models are USB bus-powered. High-density rackmount models (8-port+) feature integrated or external power supplies for maximum signal integrity.
What is the difference between an isolated and non-isolated serial adapter?
Isolated adapters use optical barriers to physically separate the electrical signals. This protects your computer from 2,500V surges and ground loops common in factory environments.
Can I use these adapters with Windows 11?
Yes, all Coolgear Serial adapters use modern FTDI or Silabs chipsets with WHQL-certified drivers for full Windows 11, Mac, and Linux support.
What is COM Port Retention and why do I need it?
COM Port Retention ensures that your assigned COM port number remains the same every time you plug in the adapter or reboot your PC. This prevents software communication errors and eliminates the need to manually reconfigure your application settings whenever hardware is moved.
How do I clean and reinstall my FTDI drivers?

How can I change my device’s COM port?
View Answer
1. Click on Start and navigate to the Control Panel
  
  Locate and click on Device Manager
  
  Under “Ports (COM & LPT)” you will find your serial device titled “USB Serial Port” along with its current COM Port.
  
  Right click on “USB Serial Port” and click on Properties.
  
  Navigate to the “Port Settings” tab and click on “Advanced…”
  
  Once there, the “COM Port Number:” can be changed with a dropdown menu to select the port number.
  
  Click your desired port number (i.e. COM2) and click “OK”.
  
  Click “OK” once more.
  
  Your serial device is now assigned to your chosen COM Port.
How do I check to ensure the COM port is listed properly in Windows?
View Answer
To ensure your serial device is installed properly, complete the following:
1. Press Windows Key + R to open the Device Manager. Once Run comes up, type “devmgmt.msc” into the text field and press Enter.
2. Expand the section labeled, Ports (COM & LPT).
3. You should now see a COM number in brackets to the right of each port. If the device is installed properly, no exclamation points or question marks should be present next to the device.
I have everything hooked up, but nothing is functioning correctly.
View Answer
To rule out potential issues, quickly test your individual components to ensure that they are working correctly individually, and are not the source of the problem:
- Serial cables
- Serial ports
- Serial devices
Test your components by:
- Hook up the serial cable(s), serial port(s), and serial device(s) in a different setup to see if the issue stems from a particular component, or the setup as a whole.
- Replace the serial cable, port, or device within your setup to further troubleshoot the issue’s origin.
When testing cables:
- Test each cable individually.
- Use short cables when you are testing.
When testing serial ports and devices:
- Press the Windows key + R, in Run, type devmgmt.msc, and press Enter to open the Device Manager. You can then check to see if your device is listed under Ports (COM & LPT).
- Ensure 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 the device is listed with an error, follow the instructions on the website to reinstall the drivers.
Serial communication is not functioning correctly, how can I tell if the problem caused by the adapter or my serial software application?

View Answer
Older serial communication applications make use of legacy hardware addresses, often incompatible with PCI, PCIe, and USB to Serial products. Contact the software provider to troubleshoot.
