Linear Timecode Cabling
The NWE-TS requires a time reference to ensure accurate watermarking. NTP is the preferred
source. If this is not available, you can use the
LTC IN BNC provided on the NWE-TS rear panel.
The NWE-TS receives Linear Timecode (LTC) on this BNC and DashBoard reports the LTC
presence in the Status tab.
This section provides an overview on cabling your LTC device to the NWE-TS rear panel. Refer
to the documentation for your LTC source for specific cabling requirements for your device.
Connecting an Unbalanced LTC Input
Before cabling, ensure that the following condition is met:
• For 59.94Hz video formats, the LTC source should be set to Drop Frame timecode as
opposed to Non-Drop Frame. SMPTE Drop Frame timecode, a SMPTE standard that
maintains time accuracy between the frame rate and actual wall-clock time, will prevent a
slight drift in a facility’s house time over extended periods of time. Setting the house
SMPTE timecode generator to Drop Frame time will prevent this cumulative timing error
from affecting the time accuracy of Nielsen’s SID (Source ID) insertions in the program
feed.
To connect an LTC input
1. Locate the LTC IN BNC on the NWE-TS rear panel. Refer to Figure 2.4 for the BNC
location.

2. Connect one end of the LTC Interface Cable to the LTC IN BNC on the NWE-TS rear
panel. Ross Video does not supply this cable.
3. Connect the other end of the LTC Interface Cable to the BNC connector on your LTC
device.

Reference ” on page 3-5.
