USB-ID
The USB-ID is a parameter to associate the USB port (COM port number) of a PC with the driver. The COM port number is
used when setting the communication port with the
MEXE02
.
If multiple drivers are connected to a PC, the PC allocates empty COM ports to the driver in the connected order. If
the driver power is turned on again or if the UBS cable is removed and inserted, the allocated COM port numbers may
change because the order of connection recognized by the PC is changed.

When the USB-ID is set
If the "USB-ID" parameter is set, the same COM port numbers are always displayed regardless of the order of connection
because the COM port number is xed to each driver. (The USB-ID and the COM port number may not match because a
PC associates with empty COM port numbers in descending order.)

USB-PID
Although the USB-ID can x the COM port number to each driver, changing the PC will also change and disable the COM
port numbers.
Meanwhile, the USB-PID is a parameter to set an ID number to the driver itself. Even if the PC or the COM port number
is changed, the product can easily be distinguished using the
MEXE02
because the ID number of the driver is not
changed.
