DM1000 Version 2—Owner’s Manual
The source select button indicators are explained below:
A usable wordclock signal is present at this input, and it is in sync with the current
DM1000 internal clock.
No wordclock signal is present at this input.
A usable wordclock signal is present at this input, but it is out of sync with the current
DM1000 internal clock.
This input is the currently-selected wordclock source.
This input was selected as the wordclock source, but no usable signal was received.
This input cannot be selected as the wordclock source because (a) a wordclock signal
cannot be sourced from this input on this type of I/O card, or (b) no I/O card is
installed.
2 Use the cursor buttons to move the cursor to a source, then press [ENTER].
The following are possible wordclock sources:
•SLOT1/SLOT2..............These buttons select the inputs from the digital I/O cards
installed in Slots 1 and 2 as the wordclock source. Inputs are
selected in pairs (odd and even numbers in this order). The
SLOT TYPE column displays the names of any installed I/O
cards. The number of pairs depends on the type of I/O card
installed.
•WC IN............................ This button selects the wordclock signal input at the WORD
CLOCK IN connector on the rear panel.
•2TRD1........................... This button selects the 2TR IN DIGITAL 1 input as the word-
clock source.
•2TRD2........................... This button selects the 2TR IN DIGITAL 2 input as the word-
clock source.
• INT 44.1k, INT 48k,
INT 88.2, INT 96k........These buttons select the internal clock generator as the word-
clock source. The DM1000 will function as the wordclock mas-
ter.
Tip:
•The FS box displays the sampling frequency at which the DM1000 is currently operating.
•The SLOT TYPE column displays the names of any installed I/O cards.
•The IN and OUT columns indicate the number of input and output channels available for
each installed I/O card.
Note: To transfer data at higher sampling frequencies (88.2 kHz or 96 kHz) between the
DM1000 and connected external devices, you need to set the data transfer format. See page 59
for more information.
Tip: If the wordclock signal is interrupted while the DM1000 is syncing to an external device,
the DM1000 will automatically switch to an internal clock (INT 44.1k/ INT 48k/INT
88.2k/INT 96k) that is closest to the interrupted clock.
