USB to RS232 Serial Converter

US-232-11A   USB to RS232 Serial Convertor   EACH $ 39.00   13 in stock   Add to Cart

This USB-to-RS232 Serial converter cable, formerly part number US-109A, will allow any USB-equipped Windows computer to converse with an RS232 device, such as a modem,  PDA, GPS device, or RS232 serial printer. Not many vendors still carry and support RS232 devices, but here at DataPro we know that old technology never really dies.

This serial converter is most popular with marine installers and technicians, who often have to deal with GPS and radar units that still depend on the RS232 serial interface. On ships big and small, DataPro's USB-to-Serial converters have provided this essential connection, as well as in military applications and industrial installations.

This device works through port emulation: when attached to the USB port on a computer, the software drivers create an emulated RS232 port on the computer which will transparently pass data from the serial device to the awaiting software.

This unit has a 1 foot long cable and can be extended with a USB extension cable or an  RS232 serial extension cable
