Details

The USB-COMi-SI-M USB to RS-422 and RS-485 Adapter with Optical isolation & surge protection is a USB powered serial adapter that is automatically detected and installed once connected to your host computer. There are no IRQ & COM port conflicts, since the port do not require any additional IRQ, DMA, memory as resources on the system. No External Power Needed!

The USB-COMi-SI-M adapter is designed with an external 4-pin dip switch to set RS-422 or RS-485 modes 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.

Optical isolation and surge protection are available where the serial line of the 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 adapter is with DIN rail bracket for industrial environment. Termination and biasing options are available for data transmission lines.
