Configuring a USB to Serial Converter

Last update - 6/25/2018

Some of the newer laptops of the past few years no longer have traditional RS232 serial ports, however the CROPSCAN MSR System can still be operated or connected to these laptops by use of a USB-to-Serial converter. Various brands of USB-to-Serial converters are available at most computer stores or from numerous computer related websites by mail order.

NOTE: Be sure to install the appropriate USB-to-Serial driver for the Windows operating system on your PC. You may need to visit the USB-to-Serial manufacturer's webpage for the latest windows drivers. Some of the older USB-to-Serial adapters are not compatible with the newer versions of Windows and you may need to get a newer USB-to-Serial adapter.
