C.2 Sync
The 8-pin mini-DIN connector lab elled Sync on the rear of the DAT-Link +, version
1.6 or later, provides access to the DAT-Link +'s synchronization, sampling-rate, and
bit clocks. The pinout of the connector is shown in Table C.2 with the pin numbers,
The DSPIN and DSPOUT pins are general purp ose parallel input and output pins for
the DAT-Link +'s DSP32C processor. They are not used by any of the existing
programs, but are available for use by user DSP programs.
The READY signal is b oth an indication that the DAT-Link + is ready to begin trans-
ferring data and also an external pause control. Whenever this signal is pulled low,
either internally or externally, the DAT-Link + is paused. Playback or recording be-
gins or continues only when this signal is b oth internally released to a high state and
external equipment is not pulling it low. It is this signal that is used to synchronize
the start-time of multiple DAT-Link +'s.
The signals, MCK , SCK , and FSYNC are either inputs or outputs dep ending on the set-
ting of the DAT-Link +'s clock source and clo ck generation parameters as describ ed
