Teac MMR-8 v3.0 - Manual (Page 21)

TASCAM MMR-8/MMP-16 Version 3.0 Owners Manual Update 21
Local Machine Response to Serial Record Commands
Serial record arm and punch in/out commands are now honored locally on each machine,
regardless of whether it is acting as an MMR Bus slave or master machine. These commands are
not propagated across the MMR Bus to other machines, and serve only to activate the machine to
which the Serial control device is directly connected.
Program Speed Play
The MMR/MMP now responds in a very controlled way to Sony Program Speed Play commands.
Previous version used a jog/shuttle mode. The status response during Program Speed Play now
indicates Play mode, with the VAR bit set in byte 2 of the Sony Status array.
Editor Mode Operation Without Video Reference
The Editor Control Mode (set via Setup Menu 000) will no longer force the Frame Reference
(Setup Menu 001) to Video, and will allow operation of the MMR/MMP without a valid video
sync reference source attached to the MMR/MMP. It is highly recommended to have such a source
when operating in this mode, and to set the Frame Reference Setup Menu to Video, but the system
will no longer require it and will allow operation even if no such source is detected. If the
controlling device is synchronizing the MMR/MMP via the serial Editor port, it is essential to
provide a video reference to insure correct operation and synchronization.
Hybrid Protocol on Serial Editor Port
The MMR/MMP internal communication protocol (TimeLine’s Hybrid Protocol) can now be
accessed via the serial 9-pin Editor control port. This is most useful for companies which want to
exercise remote control (from some other device) of MMR/MMP features not supported via any of
the other standard remote interfaces. Requests for Hybrid Protocol information and documentation
should be directed to the Marketing Director at TimeLine Vista, Inc. at (760)761-4440, or via
email request to: [email protected].
Parallel I/O Changes
Version 3.0 makes some changes to the operation of the MMR/MMP parallel control ports. These
changes are detailed here.
Dedicated Record/Rehearse ON/OFF pins
Two previously unused pins have been activated to initiate Record ON and Record OFF commands
on the Parallel Transport port. The pins activated for these commands are pin #1 for Record ON
and pin #2 for Record OFF. These pins differ from the existing Record pin in that they have no
connection to the MMR motion control unit, do not require the concurrent activation of the Play
pin, and will not affect the ONLINE status of the MMR-8. Rehearse mode may be achieved by
holding the Preview pin (pin #36) low while pulsing the Record ON pin (pin #1). The operation of
the existing Record pin (pin #35) has not changed. A chart showing the complete pin assignments
for the Parallel Tracks and Parallel Transport connectors is given at the end of this document.
