  • Overview
2-port USB-to-Serial RS-422/485 Hub

The UC4852 is the converter that transform the USB port to your computer into two asynchronous RS-422 or RS585 serial ports. This unit supports RS422/485 Auto Detect & Switch technology so when there is defined activity on the connected serial device, the convert automatically switches to the active serial port. Compatible with both USB specification 1.1 and 2.0, these device can transfer speeds up to 115.2Kbps.

Because UC4852 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.
