correct path on the Driver CD when Windows asking for the
driver's location.

Please note that if the mode were set at "422" mode, the
other settings (AUTO, ECHO and LOOP settings) will take no
effect.
The Echo mode is useful for the application program to
detect if the RS-485 bus were in a collision. If the echoed
data was not equal to the transmitted data, then the bus
was in a collision.
If you want to set the RS-485 transceiver to "AUTO" mode,
you have to go to Windows Device Manager to turn on
this option as well. You only need to do it once and the
Windows will keep the settings afterward. Please note that
S1 and S2 have its own setting. You need to go to each
port to turn on both settings.
