The ES-U-2002-M dual channel industrial 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 two 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 port doesn't require any additional IRQ, DMA, memory as resources on the system. The adapter is powered by the USB port, and no external power adapter is required. The adapter is designed with two external 4-pin dip switch ( one per port ) to set RS422 or RS485 mode conveniently, without the need to open the metal chassis. Both a 6-pin terminal block and a DB9 male connector are available on each port for optimal flexibility of serial connection. The adapter also provides a unique feature of supplying power output of 5 V / 150 mA through pin-5 of each terminal block to power an external serial device. The adapter is supplied with a removable wall mount / DIN rail bracket for industrial environments. Termination and biasing option are available for data transmission lines on each port. The USB-to-RS-422/485 Adapter provides instant connectivity to 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 communication in harsh environments. The ES-U-2002-M USB to Industrial I/O provides an industrial solution for single node or multi-drop communications over short and long distances.
