Figure 7 PcieBiSerialDb37BA22 ID and Switch Bit Map

The DIP Switch is labeled for bit number, and '1' '0' in the silk screen. The DIP Switch
can be read from this port and used to determine which PcieBiserialDb37BA22 physical
card matches each PCI address assigned in a system with multiple cards installed.
The DIPswitch can also be used for other purposes – software revision etc. The switch
shown would read back 0x12.

The Design ID and Revision are defined by a 16 bit field allowing for 256 designs and
256 revisions of each. The BA22 design is 0x03 the current revision is 0x01.
The PCI revision is updated in HW to match the design revision. The board ID will be
updated for major changes to allow drivers to differentiate between revisions and
applications.
