The OMG-USB-232 USB to serial I/O adaptors provide two, four or eight RS-232 serial ports for USB connectivity to legacy or non-USB compliant devices. OMB-USB-232 adaptors support standard PC data rates up to 460K bps.

Simply install the included software and connect the OMB-USB-232 adaptor to your USB port. The device is immediately recognized by the system. At that point, simply connect the adaptor to your target device (i.e. modem, serial printer, scale, bar code/mag stripe reader, etc.).

Now your non-USB peripherals can have the same connection simplicity and ease of use as USB aware peripherals. We include our Windows 98/ME/2000/XP and Linux drivers to simplify installation.
