5.1 Board ID Jumper J2
Jumper J2 allows the user to set the Board ID in the Board Status Register (See Section 2.1.3). This is useful to
uniquely identify a board if more than one SIO4BX2 card is in a system. When the Board ID jumper is installed, it
will read ‘1’ in the Board Status Register. The Board Status Register bit will report ‘0’ when the jumper is removed.
Refer to Figure 5-1 for Jumper J2 location.
