The converter will show up as an additional COM port in your PC's Windows Device Manager. Simply plug it into your PC's USB port using the included USB cable (3-ft.) then configure its DIP switches for 2- or 4-wire operation. Plus because it features 2000-volt optical isolation you can protect your PC and other equipment from dangerous spikes and surges on the RS-485/RS-422 network. Continue to use legacy commercial and industrial RS-422/485 devices without making any changes to the applications written for them. This compact device quickly converts USB port connections to RS-422/485 so you can connect legacy serial devices to a newer PC or laptop. LEDs indicate transmitting and receiving of data. Serial terminal block can be removed for easy wiring. Earthquake gives FiberSenses fiber sensing tech a profile boost. The USB to serial adapter features integrated optical isolation circuits and surge protection to protect your critical, sensitive control equipment against. USB 1.0 USB 1.1 and USB 2.0 compatible (12 Mbps). Without an external power supply the USB isolator can source up to 200mA at the device. Holds connections tight with its high-retention USB connector. The unit connects to a USB port for quick and simple installation and is powered by the USB port with no external power supply needed. Offers 2-wire RS-485 or 4-wire RS-422/RS-485 operation. 75.00 SKU ES-U-1101-MB Description Downloads Order Information The ES-U-1101-MB Optically Isolated USB-RS232 Adapter makes it easy to add an RS232 port to your computer. Great for linking older serial devices to computers or laptops with USB ports. The serial terminal block can be removed for easy wiring.Easily convert a USB port to RS-422/485 while protecting the USB port. The galvanic isolation barrier withstands potential difference up to 2500V. This product is an ideal solution to break ground loops, avoid noise coupling and protect ports from power surges and voltage spikes in applications which require high speed USB transfers. Simply plug it into your PC's USB port using the included USB cable (0.9m), then configure its DIP switches for 2- or 4-wire operation. USB 2.0 Hi-Speed Isolator withstands up to 2.5kVRMS. Plus, because it features 2000-volt optical isolation, you can protect your PC and other equipment from dangerous spikes and surges on the RS-485/RS-422 network. An optical isolator, or optical diode, is an optical component which allows the transmission of light in only one direction. This optical isolator adopts special chip technology, with high reliability and stable performance. At the same time, the optical isolator is a costeffective solution that allows users to easily switch between a serial server and a display. Large isolation, wide isolation bandwidth and tunability are demonstrated with lower power consumption. The nonreciprocal behavior is induced through an integrated electromagnet. Continue to use legacy commercial and industrial RS-422/485 devices without making any changes to the applications written for them. USB 3.0 SuperSpeed Isolator for electrical isolation ideal for measurement, industry, automotive and audio technology. Optical isolator is used for the conversion of highquality signal signals to a single source. We present recent progress in optical isolators and circulators fabricated though bonding magneto-optic garnet on an SOI wafer. USB to RS422/485 Converter with Opto-Isolation (SP390A-R3) The i240 USB controller requires two i312 power supplies when working with the i330 (Rev 2), since each side of the i330 optical isolator requires power. Using an optional USB Type A - Type B cable, simply plug the opto-isolator into the USB port and Windows will configure the device as an additional COM port. It doesn't require PCI or ISA slots, or IRQs. This compact opto-isolator enables you to attach an RS-232 device to a USB port and gain isolation from voltage spikes and ground loops.
