Quick Overview

USB to RS-232/422/485 Adapter with Optical isolation with 2000 volts DC & surge protection. Built-n ESD protection up to 25KV.


The USB-COMi-Si-M Now Supports RS-232 Signals RxD, TxD, GND, RTS, CTS

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 do not 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 an external 4-pin dip switch to set RS-422, RS-485 or RS-232 mode conveniently, without the need to open the metal chassis. Both a 6-pin terminal block and a DB9 male connector are available for optimal flexibility for serial connection. The adapter also provides a unique feature of supplying power output of 5V/150mA through pin-5 of the terminal block to serial device.

The adapter is with DIN rail bracket for industrial environment. Termination and biasing options are available for data transmission lines.

Optical isolation and surge protection are available with the USB-COMi-SI-M. The serial line of RS-422/485 port is optically isolated with 2000 volt DC optical isolation. The optical isolation protects your PC from spikes and surges on the RS-422/485 network, by converting the electrical pulse into an optical signal and then changing it back into an electrical pulse. The surges and spikes cannot cross the optical link. The adapter is built-in surge protector to withstand electrostatic discharge and power surges up to 25KV ESD.

The USB-to-RS-422/485 Adapter provides instant connectivity to RS-422, RS-485 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 USB-COMi-SI-M USB to Industrial I/O provides industrial solution requiring single node or multi-drop communications over short and long distance.
