I just found an older message concerning the two ways to set up MTC between 'Tools & DM. It includes some tips about automation as well. Cut/paste:
---------------------------
First - the tracking/editing setup: (based on a DM3200; for a 4800, an additional HUI extention is required.)
1. In the 'Automation' Menu, tick the MTC/USB3 box.
2. Choose 'HUI/Emulate' in the MMC Menu; check the TRA button.
3. In Protools, set up the Peripherals as shown in the attached screen shot.
4. Again in ProTools, enable the BLUE button on the PT transport: GEN/TimeCode
In this scenario, the DM will receive MTC from PTools and display it on the meter bridge and/or TMC's meters as desired. Also, full access of all transport buttons and Function keys (along with the CTRL key if required) is available.The DM RECord button is functional as well. Ptools will respond to those commands, as well as any other HUI device ('Tranzport' etc) that's been installed.

Now - for DM Automated mixing:
1. Choose GENerate INternal in the DM's MMC menu
2. In the Automation menu, choose INTernal MTC
3. In Protools, DISable the blue MTC Generate button on the transport
4. On that same transport, ENable the two blue SYNC buttons (they should flash)
At this point, Ptools will receive MTC from the DM, but the DM's RECord key is non-functional. Also, the REWIND button's behavior will revert to a 'film-style' behavior - ie - it will rewind at slightly faster than play speed. But there IS a workaround and it works very well!!.............
You'll notice there are numerals around the DM's command keypad. These are for
jumping instantly to anywhere on the time line. Markers are set in the DM marker menu - which allows up to 10 numeric place markers to be set. In an automated mixing scenario, appropriate markers might be: RTZ (00:00:00), Verse #1 (maybe: 25 seconds in), CHORUS (insert number here), etc etc. With 10 unique marking points, it's simply a matter of punching up a pre-set - from #1 - to #10, and jumping immediately to that part of the track.
Finally - the DM's automation TIMELINE and Ptool's START time must agree. If, say the Ptools start is 5 seconds in, then the DM's MTC mark should ZERO out at that point. This is necessary, because if - in the future - you come back to remix the piece after completing subsequent projects, the start time has to be in sync for the automated file to perform as expected.
