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 or RS-422/485 interfaces. To connect these devices to modern PCs you need robust and reliable conversion solutions.
The USO9ML2 and USOPTL4 are USB to Serial Converters. The USO9ML2 provides a virtual RS-232 port while the USOPTL4 is RS-422/485 compatible. Simply plug the converter into an available USB port on your computer or USB hub and the device will show up as an additional COM port in the Windows Device Manager.
Commercial and industrial equipment such as point-of-sale peripherals, medical devices, scientific instrumentation, laboratory equipment and other devices are often used in environments where surges, spikes and ground loops are likely to occur. The built-in 2KV optical isolation provided by the USO9ML2 and USOPTL4 will protect sensitive equipment used in industrial environments.
Both models provide full speed (12 Mbps) USB 2.0 support allowing connectivity with modern computer technology.
The USO9ML2 RS-232 port uses a DB9 Male connector wired as a DTE with full hardware handshake support while the USOPTL4 provides screw terminal connections. Dip switches allow the USOPTL4 to be configured for two-wire or four-wire, RS-422 or RS-485 modes. By supporting both 2-wire RS-485 and 4-wire RS-422/485 communications, these devices are great for any application that requires long range or multi-drop capabilities.
Both converters can handle standard asynchronous data rates up to 460.8 Kbps.
Each unit comes with 1 meter USB cable and a driver disk. Drivers support Windows platforms up to Windows 7 in 32 and 64 bit implementations.
