FAQ
What is the purpose of COM port retention in this adapter?
COM port retention ensures that the adapter maintains the same COM port assignment across system reboots or reconnections. This stability is crucial for legacy software and devices that rely on consistent port identifiers, preventing configuration errors and simplifying management in multi-device setups.
Does this adapter require external power?
No, the ICUSB422 is USB bus-powered, drawing all necessary power directly from the USB port. This eliminates the need for bulky external power adapters, making the adapter more portable and easier to install in environments with limited outlet access.
What chipset does the ICUSB422 use, and why is it important?
The adapter uses the FTDI FT232RL chipset, known for its reliability and broad driver support across operating systems. This chipset enables features like COM retention and customizable baud rates, ensuring compatibility with a wide range of legacy serial devices and reducing installation headaches.
What is the maximum baud rate supported?
The ICUSB422 supports a maximum baud rate of 921.6 kilobits per second (Kbps). This speed is sufficient for most RS422/485 applications, including data acquisition, industrial control, and point-of-sale systems, balancing performance with stable communication.
Is this adapter TAA compliant?
Yes, the ICUSB422 is TAA (Trade Agreements Act) compliant. This certification makes it eligible for procurement by U.S. federal, state, and local government agencies, as well as institutions that require products manufactured in designated countries, ensuring it meets strict trade regulations.
What environmental certifications does this product have?
The adapter complies with EU RoHS (Restriction of Hazardous Substances), REACH (Registration, Evaluation, Authorization, and Restriction of Chemicals), and WEEE (Waste Electrical and Electronic Equipment Directive) standards. These certifications confirm that it meets stringent environmental and safety requirements for hazardous material restrictions and recycling.
What refresh rate or brightness details are available?
Display-oriented products are best judged through screen, connectivity, and installation specifications. Those facts help buyers confirm visual fit, mounting flexibility, and deployment suitability more clearly than generic summary text.
What input or connectivity options are listed?
1 x 9-pin DB-9 RS-422 Serial - Male.
