LTC Input (Rx) Sources Each SDI channel can select sources for its respective LTCA thru LTCD encoders from the
following:
- Audio LTC from Chan A thru D Emb 1-16 input, AES 1-16, MADI 1-64.
- RS-485 LTC from COM1 or COM2.
- Timecode source priority selection from reference VITC, VITC waveform, ATC_VITC,
ATC_LTC, or free-run timecode as source.
LTC Output (Tx)
Destinations Each respective LTCA thru LTCD encoder is independently related to each SDI input channel,
and can output LTCA thru LTCD independently (as source choices LTCA thru LTCD) to the
following destinations:
- SDI Chan A thru D VANC (as VITC waveform, ATC_VITC, or ATC_LTC as applicable for
video format).
- Output audio LTC over SDI Chan A thru D Emb 1-16 output.
- Audio LTC to AES 1-16, MADI 1-64
- RS-485 COM1 or COM2.
LTCA thru LTCD can be used as sources for any audio channel or SDI output channel.
(9372 card has only LTCA and LTCB encoders; 9371 card has only LTCA encoder.)
