Introduction Introduction
Introduction
Thank you very much for purchasing our product of USB-402.
USB-402 is an 8 channel USB to RS485/RS422 converter that isolated bet een
each RS-485/422 serial port and a USB port. You can use 8 channels of RS-485/422
serial port from a USB port. Those 8 channels are isolated independently from USB
side.
