Interfacing To A Video Editor - Alesis AI-2 Reference Manual

Note, that the ADAT SYNC OUT connector on the AI-2 rear panel is
unconnected for this mode of operation.
When all connections have been made, and the units powered on,
the BRC/ADAT LED on the front panel of the AI-2 should be
illuminated, to indicate that valid communication is occurring
between the units. If the LED does not light (no communications)
or is flashing (communication taking place, but with errors), then
recheck the cable connections.

3.3 INTERFACING TO A VIDEO EDITOR

The AI-2 can be used to connect ADATs to a video editing system
or other editing devices. The AI-2 provides a 9-pin SONY protocol
VTR emulation for the ADAT transport. The AI-2 offers a number of
editor specific functions such as selectable E-E and record field
options and a comprehensive track mapping menu that maps editor
track enables to selected ADAT tracks or machines.
Connect a standard RS422 cable from the 9-pin EDITOR connector
in the control section of the AI-2 rear panel to a control output port
on the editor. Connect a video reference signal to the VID IN
connector in the reference section of the AI-2 rear panel. This
video reference can be either black burst, color bars or composite
sync, at either video or sync levels. The AI-2 normally emulates the
SONY PCM-7030 DAT recorder, if the editor does not recognize
this ID then the AI-2 emulation can be set to BVU950. Consult the
Appendix for further details about emulation constants.
