Industrial USB RS-232/485/422
Opto-Isolated Converter
Part Number: USB-Serial-3 (DIN-Rail/Wall-Mount)
■ INTRODUCTION
The USB-Serial-3 is a rugged, industrial-grade, 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, noise problems, ground loops, remote lightning and spikes. The unit is powered from
the USB port and it features data format auto-sensing and self-adjusting; therefore, no DIP
switch or jumpers are required. The unit can be used to communicate with one loop of up to
128 units of RS485/RS422 devices. When working with RS-485 signals, the CommFront's
auto-turnaround feature eliminates the need for flow control. The unit uses the latest chipset
from Silicon Labs and is fully compatible with Windows 10/8/7/Vista/XP/Server2003/2000
(32-bit), Windows 10/8/7/Vista (64-bit), Win CE (5.0, 6.0), Mac OSX, and Linux (2.6x,
2.4.36). Note: the latest drivers (chipset: Silicon Labs' CP210x) are available at
