The ES-U-3008-RM USB-to-Octal RS232 / RS422 / RS485 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 RS232, or RS422, or RS485 serial communication ports to your system. By taking advantage of the USB bus, the USB Serial Adapter makes it easier than ever to add serial ports and serial devices to your system with easy plug-and-play and hot plug features.

By plugging the USB Serial Adapter to the USB port, the adapter is automatically detected and installed. There are no IRQ & COM port conflicts, since the ports do not require any additional IRQ, DMA, memory as resources on the system. The adapter is self-powered, and has built-in switching power supply of 100 V / 240 V (input) inside the chassis.

The adapter is designed with eight external 4-pin dip switches to set RS232, RS422 or RS485 mode conveniently, without the need to open the metal chassis. Each port can be independently set to RS232, RS422, or RS485, depending on your requirement in application. The adapter is supplied with DIN rail brackets for an industrial environment. The adapter can be also mounted to a 19" rack, and the rack mount kits are included with the adapter. Termination and biasing option are available for data transmission lines.

The USB to 8 port RS232 / RS422 / RS485 Adapter provides instant connectivity to RS232,RS422, RS485 communication devices for POS, factory automation equipment, multi-drop data collection devices, bar code readers, time clocks, scales, data entry terminals, PC to PC long distance communications, ATMs and serial communicationin harsh environments. The ES-U-3008-RM USB to Industrial I/O provides industrial solution requiring single node or multi-drop communications over short and long distance.

Complete driver support for all current Windows, Linux, and  MAC-OS platforms. All drivers are downloadable for free.
