The USB-COM-2SM is a two-port asynchronous serial communication adapter designed for use with any computer system equipped with a USB port. Multiple peripherals such as POS, barcode scanners, scales, date-entry terminals, data acquisition modules, and automation equipment can now be recognized and used on a single USB port. Simply install the included software and connect the unit to your USB port. It instantly provides two RS-232, RS-422, or RS-485 serial ports which can be selected on a port by port basis. It is now easier than ever to add serial ports and serial devices to any application along with easy plug-and-play and hot-swapping features.

The unit enclosure is 4 inches wide by 4 inches deep by 1.8 inches high. The adapter is supplied with a 6 foot USB cable and has two male DB9 connectors with jack-screws for secure cable connections. The DB9 connectors are conveniently located at the front of the unit and feature easy-to-read LEDs indicating serial port activity. The USB connector is located at the back of the unit and also features a LED for USB status.

The USB-COM-2SM is fully compatible with both USB 1.1 and USB 2.0 ports. The OEM (board only) version provides just the board without the enclosure and is ideal for a variety of embedded OEM applications. An additional USB input header is provided on the board for OEMs along with a downstream USB port for connecting additional USB devices.
