Description

The USB to Octal Serial Adapter is designed to make serial port expansion quick and simple. Connecting to a USB port on your computer or USB hub, the USB Serial Adapter instantly adds eight RS-232/422/485 multi-electrical interface serial communication ports to your system. By taking advantage of the USB bus, the USB Serial Adapter makes it easier than ever to add 8 serial ports and serial devices to your system with easy plug-and-play and hot plug features. Adapting the new technology, the serial port expansion now takes the new bus with easy and convenient connectivity.

Plugging the USB Octal Serial Adapter to the USB port, the adapter is automatically detected and installed. There are no IRQ & COM port conflicts, since the port doesn’t require any additional IRQ, DMA, memory as resources on the system. The RS-232, or RS-422/485, port functions as native Windows COM port, and it is compatible with Windows serial communication applications. Each port is individually configurable. The adapter is designed with external switches to set RS-232, RS-422 or RS-485 ports and different operation modes conveniently. There is no need to open the chassis to set the ports.

The USB Serial Adapter provides instant connectivity to RS-232, or RS-422/485, communication devices for factory automation equipment, multi-drop data collection devices, barcode readers, time clocks, scales, data entry terminals, ATMs and serial communication in harsh environment. The USB to Serial Adapter is suitable for remote access, retail and industrial application, data collection and other applications requiring high speed RS-232, or RS-422/485, communication ports.
