2.3.3.2 Board ID Function (SW1)
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 Table 2.2.
After COM ports have been created, the COM port number will be linked to the board
ID even if the card is moved to a different PCI/PCIE slot. This is a useful function for
maintenance and mass production applications.
(PCI-1620A/PCI-1620B/PCI-1622B are SW2)
