Quatech - USB to RS-232 Serial Adapters

Connect Multiple Serial Devices to Your Computer

If you have a thermal ticket printer connected to your computer's serial port, and you would like to add other serial (RS-232) devices, such as a receipt printer, cash drawer, debit card pin pad, or any other serial devices supported by Box Office Xpress, then you will need a serial adapter.

We have tested the above 4 port unit from Quatech with a variety of serial devices and have found it to work flawlessly. This unit plugs into a USB port and adds the appropriate number of serial ports to your computer.
