Board ID Setting
The comm. cards feature a built-in DIP switch for defining
the card’s board ID. When multiple cards are installed, the
board ID switch is useful for identifying the device number
of each card.
After setting each COM card, you can identify each
card installed in the system according to their device
numbers. The default board ID value is 0 (disabled).
To adjust the board ID value, configure SW1 according to
below table:
