FAQ: Common USB to Serial Adapter Questions
Q: What is COM Port Retention and why do I need it?
A: 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.
Q: Can I use these adapters with Windows 11?
A: Yes, all Coolgear Serial adapters use modern FTDI or Silabs chipsets with WHQL-certified drivers for full Windows 11, Mac, and Linux support.
Q: What is the difference between an isolated and non-isolated serial adapter?
A: 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.
Q: Do these adapters require an external power supply?
A: 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.
