9035 PRODUCT MANUAL

9035-OM (V4.4)

(continued)

Audio LTC and RS-485 LTC controls described below only appear on cards with +LTC licensed optional

feature. This feature allows bidirectional conversion between VBI-based timecode and LTC timecode on audio and RS-485
interfaces.

• Timecode Source Status Displays

Displays the current status and contents of the supported timecode
formats shown to the left.

• If a format is receiving timecode data, the current content (timecode

running count and line number) is displayed.

• If a format is not receiving timecode data, Unlocked is displayed.

• If Audio LTC is being received, the timecode running count is

displayed.

Audio LTC Source selects audio source to be used by card audio

LTC function as listed below.

• Emb Ch 1 thru Ch 16

• AES Ch 1 thru Ch 16
• Analog audio Ch 1 thru Ch 8

Note: Audio LTC Source must be appropriately set for card to receive
and process audio LTC.

• RS-485 Port LTC Control

Allows RS-485 port to be used to receive LTC, or send LTC over RS-485
port as follows:

• If RS-485 LTC is to be received via the shared RS-485 port, set the

RS-485 Port Function control to LTC In.

• If RS-485 LTC is to be outputted via the shared RS-485 port, set

the RS-485 Port Function control to LTC Output. The timecode
string carried on the LTC output is that selected using the Source
Priority
controls described on the next page.

• Incoming ATC Packet Removal Control

Enables or disables removal of existing input video ATC timecode packets
from the output. This allows removal of undesired existing timecodes from
the output, resulting in a “clean slate” where only desired timecodes are
then re-inserted into the output. (For example, if both SD VITC Waveform
and SD ATC_VITC timecode data are present on the input video, and only
ATC_VITC is desired, using the Removal control will remove both
timecodes from the output. The ATC_VITC timecode by itself can then be
re-inserted on the output using the other controls discussed here.)
