Connect and isolate serial/legacy equipment on your PC or laptop USB port.

Connect RS-232 or RS-422/485 devices to your USB (Universal Serial Bus) port with 3000 V RMS optical isolation protection from voltage spikes and group loops. These products draw power from the USB port so no separate power supply is required. 2 or 4 port models, USB 1.0/2.0, pluggable terminal blocks.

Simply plug the converter into an available USB port on your computer or USB hub and the device will show up as additional COM ports in the Windows Device Manager. Configured as additional COM ports, the converter is compatible with your Windows applications.

USB to RS-232 Isolated Converters

Models USO9ML2-2 and USO9ML2-4 are USB to isolated RS-232 port converters. RS-232 ports are configured with DB9 male connectors. Each port has a pair of LEDs that show when RS-232 data is being received or transmitted. The USB side is configured with a USB type-B female connector. Supports all handshake lines (RTS,CTS,DTR,DSR,DCD,RI)

USB to RS-422/485 Isolated Converters

Models USOPTL4-2 and USOPTL4-4 are USB to two and four port RS-422/485 converters. Supporting 2-wire RS-485 or a 4-wire RS-422/485 communications, these devices are great for applications requiring long-range or multi-drop capabilities. Both models use pluggable terminal blocks on the RS-422/485 side and have a pair of LEDs for each port that indicate data being transmitted or received.

Your USB Port: A Bridge Between Legacy Devices and Today's PCs, Laptops

Universal Serial Bus (USB) has become the connectivity workhorse of today's PCs, replacing the familiar serial port. But many commercial and industrial devices still use RS-232 interfaces. To connect these devices to modern PCs you need robust and reliable conversion solutions. At the same time, USB ports are becoming more common on commercial and industrial equipment such as point-of-sale peripherals, medical devices, scientific instrumentation, laboratory equipment and other devices. Sometimes these are used in environments where surges, spikes and ground loops are likely to occur. Protect your valuable equipment investments with isolation protection from B&B Electronics.
