FAQ
What is COM port retention and why is it important?
COM port retention refers to the adapter's ability to save assigned serial COM port values in built-in non-volatile memory. This is important because it allows the adapter to automatically reassign the same COM port values when reconnected, even to different USB ports. This eliminates the need for manual reconfiguration and ensures consistent device recognition, which is critical in applications where specific COM port assignments are required for software compatibility.
What is the maximum cable length and data transfer rate?
This adapter cable measures 16 inches (40 centimeters) in length, providing practical reach for desktop and workstation setups. It supports a maximum baud rate of 921.6 Kbps with a 512-byte FIFO buffer for efficient data handling. The adapter accommodates various data configurations including data bits of 5, 6, 7, or 8 and stop bits of 1, 1.5, or 2, making it compatible with a wide range of serial equipment.
Does this adapter require external power?
No, the ICUSB232PROC adapter is USB bus powered, meaning it draws all necessary power directly from the host computer's USB-C port.
