Configuring the Time Reference
The NWE-TS requires an external time source in order to accurately encode the time-of-day into
the audio stream. A variety of external time sources are supported. Without an external time
source, the encoded time-of-day will drift over extended periods.
Specifying the Time Reference Input
The options in DashBoard enable the selection of time/date source, configuration of applicable
time-zone offsets, and Daylight Savings Time (DST) adjustment parameters such as whether the
LTC input follows DST. This section also outlines how to set the time manually, in case the time
input is temporarily unavailable.
To specify the time source
1. Select the NWE-TS node in the Tree View of the NWE-TS you want to configure.
2. Select the Configuration tab in the Device View.
3. From the Time Reference area, specify the type of time reference input by choosing one
of the following:
• System Clock — Select this option to use the date and time as reported by the
NWE-TS internal clock. Refer to the section “ To manually set the date and time
for the System Clock ” for details on configuring the internal clock.
• NTP (Network Time Protocol) — Select this option to obtain the date and time
from a NTP server via the ethernet connection on the NWE-TS rear panel. Enter an
IP address for an NTP server that is accessible through your network.
• LTC — The time of day is obtained from the timecode signal connected to the LTC
BNC connector on the NWE-TS rear panel.
4. When using an LTC input, specify whether your LTC device automatically adjusts for
Daylight Savings Time (DST) by configuring the LTC Observe DST check box as
follows:
• Select the check box if your LTC device connected to the NWE-TS automatically
adjusts for DST.
• Clear the check box if your LTC device connected to the NWE-TS does not
recognize DST. This is the default setting.
• You will also need to set the Encoder Date as outlined in step 2. in the procedure
“ To manually set the date and time for the System Clock ” below.
• You may also need to specify an offset as outlined in the section “ Specifying an
Offset ” on page 3-6.
5. From the Time Zone menu, specify the time zone your facility is located in.
6. Click Set Time Reference .
7. Verify that the Encoder Date and Encoder Time fields in the Status tab are correct.
Note
— The NWE-TS requires an NTP or LTC input for accurate timekeeping. If this is
temporarily unavailable, you can also select the free-running System Clock; however this is not
suitable for live system operation, as it will drift over time.
