2.4 Setting the BoardID Switch (SW2)
You can use the BoardID command (0x20) to get the board's unique iden-
tifier. PCM-3753I has a built-in BoardID SMD switch (SW2), which is
used to define each card's unique identifier. You can determine the identi-
fier in the register as shown in Table 2.2. When there are multiple cards
on the same chassis, this BoardID setting is useful for identifying each
card's device number. We set the PCM-3753I's BoardID switch to 0 at the
factory. If you need to adjust this setting, please see below.
