4-port USB to serial RS-422/485 hub 

compliant with USB 1.1 and USB 2.0 

UC4854 is a converter that transform the USB port of your computer into 4 asynchronous RS-422 or RS-485 serial ports. UC4854 hub provides an external plug-and-play RS-422 / RS-485 serial connection for computers, notebooks, laptops, and handheld computing devices that support the USB specification.

This unit supports RS422/485 auto detect & switch technology so when there is defined activity on the connected serial device, the converter automatically switches to the active serial port. Compatible with both USB specification 1.1 and 2.0, this device can transfer data at speeds of up to 115.2 Kbps.

Because UC4854 operates with plug-and play ease (under Windows) or with the provided Linux driver via a USB port interface, it doesn't require any IRQ, DMA or I/O addressing resources. Embedded electrostatic surge protection prevents damage to serial devices caused by air discharges as high as 15,000 volts.

UC4854 provides a quick, simple, and cost-effective solution and is ideal for various communication and automation applications.
