The Timecode Sub-Menu

The DA-88, when equipped with the SY-88 timecode card, has a complete synchronization feature set for automation systems, transfers, video post-production, and MIDI environments. The SY-88 has it's own software which has gone through a number of revisions (4.01 has been the latest since the late-90's). There is an extended SY-88 sub-menu that is "hidden." This chart describes these settings. The four most important items for most users are numbers 1, 2, 3, and 6. The rest are for controlling the DA-88 with a 9-pin video controller, etc. (For more, download the original SY-88 manual and the SY-88 v4 supplement. Also see the RC-848 remote v4 manual.) Other models made after the DA-88 have more user-friendly menus.


To enter the timecode menu:

First, put the display in TC mode: Either press the DISPLAY button until the TC light glows, or just hold DISPLAY and press the DOWN arrow.

To access the TC sub-menu, press both the UP and DOWN arrows. Then press DISPLAY to scroll down through the 23 items described in the chart below.

(To scroll up, hold the UP arrow and press DISPLAY. To exit the menu, hold DISPLAY and press the DOWN arrow.)



Before SY-88 software version 4.00 and DA-88 software 3.10, the menu only had items 1-3. In these early versions, timecode timing (selection six) is toggled by holding the UP key and pressing DIGITAL IN. Also, when in MIDI mode (dip S1 #2 =up), menu items 1-3 are the only items accessible, even if you have software version 4.

To Engage Timecode Pull-up/Pull-down:

With display in TC window, hold down the UP arrow and press Fs (sample rate selection, next to the FORMAT button). The UP and DOWN arrows will then cycle through:

...PULL OFF, PULL DOWN, PULL UP Non-Drop frame, PULL-UP Drop frame...

To change from ABS mode to TC mode:
This determines whether a slave DA-88 in a multi-DA-88 setup follows ABS coming into the sync jack or follows SMPTE coming into the TC jack (SY-88 version 4.01 only). When the display is in ABS mode, simultaneously press the UP and DOWN arrows. The arrows will then toggle between "P.in ABS" and "P.in TC." Note that this does not affect the TC jack...

To change the expected TC at the TC jack, put the display in "TC" mode, then simultaneously press the UP and DOWN arrows.

To put the DA-88/SY-88 in "MIDI mode," put S1 dip #2 up (on). To send Midi TimeCode (MTC) out, turn on internal dip S2 #8. There are also two internal dip switches that need to be on for MIDI Timecode to be output when in stop mode (S2 #6) and ff/rew (S2 #7).

Read DIP Switches and change affected menu items (DIPs are usually only referenced at start-up):

PRESS EITHER THE UP ARROW OR THE DOWN ARROW


S1 External Dip Switches


These determine how each setting will be upon startup. They can be temporarily overridden via the Timecode Submenu, but will change back upon the next restart.

Down (Default)

Up

Notes

1 75 ohm termination for the video reference input Leave the switch down if nothing is plugged into the VIDEO THRU jack. Set to up when the VIDEO THRU jack is connected.  
2 SERIAL IN: Submits the DA-88 to control signal from its RS-422 port or MIDI terminal. Selects the RS-422 port (9-pin). Selects the MIDI IN terminal. The RS-422 port can be activated only when the DA-88 is in its timecode controlled mode (not ABS time mode).
3 CHASE MODE "Rechase" mode: The SY-88 reads and compares the master and slave timecode numbers constantly to control the slave machine with respect to the master. "Free" mode: The slave machine (DA-88) is set free from the master after both achieve lock, and starts playing independently of the master.  
4 RECHASE: Determines the threshold of rechase function Each time the difference between the master and slave timecode numbers is greater than 1 second, the slave machine will be nudged back into sync. Selects a threshold of 2 seconds. Effective only when the #3 CHASE MODE switch is Down (Rechase).
5 TC OUT TIMING: To compensate for the 42 sample delay casued by the D/A converters Timecode is sent out in time with respect to the analog audio output. Timecode is sent out in time with respect to the digital audio output. IMPORTANT: This switch must be set according to the audio outputs you are actually using; eg. if analog outputs are in use, you must set the switch to Down regardless of whether the DA-88 is in regular mode or in Digital Output (Digital Dubbing) mode. For these modes, see the DA-88 manual supplement 5700142301.
6 MIDI TC source select MTC (MIDI Timecode) translated from SMPTE/EBU code read from the DA-88 tape or generated from the SY-88 is sent out the MIDI OUT jack. The MIDI OUT jack is fed with MTC derived from the timecode input. No compensation is applied to the signal.  
7 Video Sync Playback For timecode based chase and sync. The DA-88 locks to rising edges of the video frame (for video emulation). Determines, when the DA-88 is slaved to a VTR, whether sync is achieved using timecode or the DA- 88 locks to rising edges of the video frame ignoring the actual timecode numbers.
8 CONTROLLER: what's connected to the ACCESSORY RS-422 port Leave the switch at this position if your controller is “TYPE 1” and capable of transmitting a chase command. Set the switch to this position if your controller is "TYPE 2” and does not transmit any chase commands. Note: If switch #7 is in the Down position, switch #8 has no effect.
