The USB-Serial-3 is an industrial-grade (wide temperature range with surge & static protection) optically-isolated USB to RS-232/485/422 converter, which can be used to convert any standard USB port into a three-wire RS-232 port, a two-wire RS485 port, or a four-wire RS422/RS485 port and vice versa.

This product features opto-isolation circuitry, which effectively protects your USB devices from transient surges, ground loops and spikes.

The unit uses the latest chipset from Silicon Labs and is fully compatible with Windows 8/7/Vista/XP/Server2003/2000 (32-bit), Windows 8/7/Vista (64-bit), Win CE (5.0, 6.0), Mac OSX, and Linux (2.6x, 2.4.36).
