Locked Serial Numbers
Many B&B Electronics USB to Serial Converters
have a ‘locked serial number” version noted by the
model number suffix “-LS”.
The LS version locks the USB serial number. This
lets multiple devices with the same model number
be used on multiple computers without installing a
driver for each individual product.
For example, in field service applications tools are
often shared. If the serial number was not locked,
each converter would need to be installed on every
PC in the pool.

Troubleshooting
One USB port is required for each installed
device. The USB port can be native to the PC or
it can be a USB port on a USB hub that is
connected to a PC.
To verify the installation you may open the
Windows Device Manager Scroll down to Ports.
Expand the flyout window. You should
see the new ports. If there are no exclamation
points or other trouble indicators ports are
installed correctly and ready for use.
