AES Sync In
(3-pin Lemo Female) AES/EBU formatted sync input. The
DF64 clocks to the signal at this port when Sync Source is set to
AES. An XLR female to LEMO adapter cable is provided.
AES Sync Out
(3-pin Lemo Male) AES/EBU formatted sync output. This
signal is active regardless of the selected sync source. A LEMO
to XLR male adapter cable is provided.
Word In
(BNC) TTL-level square wave Sync Input. DF64 Sample
rate is clocked to the signal at this port when Sync Source is set
to Word.
Word Out
(BNC) TTL-level square wave sync output. This signal is
active regardless of selected sync source.
IEEE 1394 ports (2)
(IEEE 1394) High speed communication interface to the
SC253d Pilot Computer. This interface carries real-time control
and metering data between the SC253d and the DF64. The
cable from the SC253d can be plugged into either of the two
ports.
Chassis ID Display
Each DF64 chassis must be assigned a unique ID which
identifies it among multiple frames in a system. The ID is set
using a rotary switch located on the Backplane PCB. The
System is shipped with the ID switch preset to the proper
number, so users will not normally need to access the switch.
The switch position must match that of the corresponding Digital
Pilot computer.
Sync Source LEDs
The top three LEDs in the Sync Source section indicate
the selected sync source: AES, Word, or Internal. The sync
source is changed by pressing the select button (a paper clip or
similar tool is required) Refer to the System 5 Operation Manual
for information on changing the sync source.
Sample Rate LEDs
The bottom six LEDs in the Sync Source section indicate
the sample rate that is measured by the FC-631 card. Standard
sample rates include 44.1kHz, 48kHz, 96kHz, and the 0.1% “pull-
up” and “pull-down” rates associated with each of these standard
rates. If the FC631 is locked to a non-standard sample rate, the
CUSTOM LED will be lit.
Select Button
Use this button to manually select the Sync source (and
Sample Rate, if Internal Sync is selected) Refer to the System 5
Operation Manual for information on changing the sync source.
Locked LED
Indicates that the FC631card is receiving and locked to
the selected sync source.
This LED must be lit to ensure
proper audio operation of the DF64.
.
Active LED
When lit, Indicates that the FC631 is actively controlling
the TDM bus. In a system with two FC631 cards, this LED is
