The OMG-USB-SER USB to serial I/O adaptors provide two, four or eight RS-232/422/485 serial ports for USB connectivity to legacy or non-USB compliant devices.
Each port is individually configurable for RS-232, RS-422 or RS-485 communications via internal dip switch settings. OMB-USB-SER adaptors support standard PC data rates up to 921.6K bps. Simply install the included software and connect the OMB-USB-SER 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 XP/Vista/7 and Linux drivers to simplify installation.
