USB to Serial User Manual About Multiport(Multi-N) USB series USB is a complex word of “Universal”, meaning all peripheral devices use the same connector, and “serial”, meaning devices are connected as a daisy chain through serial transmission. USB is an interface suggesting a solution to inconvenience and inefficiency caused by slow speed and limited device connection of existing external ports (serial or parallel).
