(continued)

• Timecode Source Status Displays Displays the current status and contents of the supported external 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, Not Present is displayed.

• LTC Input Control

Selects source (RS-485 port LTC A or LTC B) to be used by card to receive

LTC.

Note: • Input LTC must be appropriately set for card to receive and process

received LTC.

• Card LTC inputs will not center inputs with DC offset. If input has DC

offset, the source may need to be capacitively coupled to remove the

offset.

• Mute LTC Control Allows RS-485 LTC output to mute upon loss of selected timecode inputs.

• When set to Enabled and input timecode is lost, RS-485 LTC output goes

to frozen state.

• When set to Disabled and input timecode is lost RS-485 LTC output keeps

counting, with count value being free-run count.

Note: If muting upon loss of a particular input format is desired, set all

Source Priority 1 thru 4 to that particular input format. If this is not

done, the card failover timecode selection may substitute another

format choice for the format not being received.

• 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 SDI ATC_VITC and

ATC_LTC are present on the input video, and only ATC_LTC is desired,

using the Removal control will remove both timecodes from the output. The

ATC_LTC timecode by itself can then be re-inserted on the output using the

other controls discussed here.)
