Locked Serial Numbers Explained
We configure our single-port USB to serial converters in two ways. In
standard format, each product has a unique serial number. “Locked serial”
format uses the same serial number that is associated with a model type.
If your converter will always be used with the same computer, the standard
serialized model is all you need. If the converter is shared among several
computers, like field service laptops, the locked serial number model lets
you plug and play without having to worry about matching the two.
