In all other cases, the data is transferred according to
the following table, where the numbers represent the
track which is being transferred. Italicized numerals
(e.g.

connections
The DA-98HR is equipped with sophisticated facili-
ties for control and synchronization with other units.
For full details of how to operate the DA-98HR with
other DTRS units, see 8, "DTRS synchronization",
and for details of timecode synchronization, see 9,
"Operations related to timecode".
3.2.1
Analog timecode connections
The DA-98HR can be synchronized to externally-
generated timecode and is also equipped with an
internal timecode generator.
The two XLR timecode connectors
anced signals with the following polarity:

If the DA-98HR is the last unit in the chain of video
equipment, there is no need to terminate it, as this
circuit is self-terminating.
For details of how the DA-98HR can be synchro-
nized to video frame information, see 9.7, "Video
resolution".
