Installation Notes
These USB to serial converters are offered as serialized
(each unit has a unique electronic serial number) or with
locked serial numbers (each unit has the same
electronic serial number). LS models are great for
applications, such as field service, in which a pool of
converters area shared.

SEARIALIZED
– Select a serialized model if the USB to
serial Converter is to be assigned to a unique COM port.
If you plug in a converter with a different serial number,
the driver installation procedure will be initiated again.
This will also allocate another COM port and USB
Controller in Windows. This will happen even if the first
converter is not plugged in.

LOCKED SERIAL NUMBER
– Select a locked serial
number model (-LS suffix) if you desire different USB to
serial converters of the same type to share a single
COM port (one at a time). With the locked serial number
models, you only need to install the driver once,
provided two converters are not plugged in at the same
time. The locked serial number products are intended for
uses, such as field service, in which PC’s and
converters are mixed and matched.
