Connect the Converter
1
Connect the converter’s USB Port to a USB port on your computer or
USB hub.
When the installation is complete the converter will appear in
Windows Device Manager as an additional COM port.
Most of the time a DB9 male will be a DTE. A DB9 female will usually
be a DCE.
A DTE device is “Data Terminal Equipment.” This includes computers,
PLCs, and most devices that are not used to extend communications.
(Think COMPUTER for DTE.)A DCE device is “Data Communications
Equipment.” This includes modems and other devices that extend
communications like RS-422/485, ber optic converters or radio
modems. (Think “MODEM” for DCE.)
USB
Port
If both devices have a DB9 male connection you will need a crossover
cable. If both devices have a DB9 female connection you will need a
crossover cable.
When one device is male and one device is female, use a straightthrough cable.
Check LEDs

When everything is installed and connected the LED will blink to let
