The 'Properties' tab states the current configuration and allows the user to test it by clicking on the 'Test This Port'. The example below indicates that 'COM4' is selected and the MD22 spectrophotometer should have no problem communicating with the PREVU* and Cholesterol 1,2,3 software providing that 'COM4' is selected in that software's 'Options' window. Go to Windows 'Start' > 'All Programs' > 'Keyspan USB Serial Adapter' > 'Keyspan Serial Assistant' to access the following window that will default to the 'Adapter Status' tab indicating which communications port the adapter is mapped to.If the 'Keyspan model USA-19HS' has been installed, follow these directions: If the customer has installed a USB to serial adapter, properly connected the spectrophotometer, and still receive a communications error when opening the PREVU* and Cholesterol 1,2,3 software the adapter could very well be selecting a communications port other than the required 'COM1', 'COM2', 'COM3', or 'COM4'.

Some X-Riteproducts, such as PREVU* and Cholesterol 1,2,3, must be connected to ports mapped to 'COM1', 'COM2', 'COM3', or 'COM4' in order to communicate with the spectrophotometer. It is this 'Keyspan USB Serial Adapter Assistant' that will allow a user to change port mappings on the PC to select the required 'COM1', 'COM2', 'COM3', or 'COM4'. It ships with a software installation CD that will install drivers, a users manual, a useful Help file, as well as the 'Keyspan USB Serial Adapter Assistant'. X-Rite recommends the 'Keyspan model USA-19HS' USB to serial adapter.

In the event that a customer has purchased a serial device and is attempting to connect it to a PC that does not have a serial port but does have a USB port, a USB to serial adapter should work.
