DIP SW1 and SW2 — Reference Select
SW1
and
SW2
are used in combination to select the reference source of the ADC-8432.
•
In the case where an external reference is used, the sample rate is determined by the
external reference. If the external reference is lost,
SW3
,
SW4
, and
SW5
dictate the
sampling rate. If the reference is re-established, the sample rate returns to the sample
rate dictated by the reference signal. The reference must be an AES or DARS signal.
•
In the case where the card uses the internally generated reference signal,
SW3
,
SW4
and
SW5
inform the card of the sampling rate to use. Refer to Table 2 for details.
Table 1
lists the combination of DIP Switch settings for
SW1
and
SW2
.
