SDI A Output Video
The timecode source channel controls (in this example,
Timecode A) are set to receive and insert (output)
ATC_VITC as described earlier in this section.
Using the COM Routing tab, the SDI A LTC encoder
output LTCA is set to output over COM1, while COM2 is
set as an input to receive the LTCA timecode (a jumper
is required between the two ports).
Shown below is an example in which received VBI ATC_VITC timecode on SDI A is transferred (copied to) SDI B using the
two RS-485 ports on the card.
Using the Timecode B tab controls, this channel is set to receive an imported
RS-485 LTC (in this example, jumpered over from LTCA), and prioritize to only
use this timecode.

SDI B Output Video
(w/ copied timecode
import)
Because no native timecode exists in the SDI B input
stream, and ATC_VITC is desired as an output, the
Timecode B HD ATC_VITC Insertion control is set to
Enabled.
The Output Status display shows that the imported
RS-485 LTC timecode is being used to generate the
timecode output for SDI B.
