Using the SiteSync IQ Remote Transmitter as a Time Server
The SiteSync IQ Remote Transmitter with the Ethernet port can be used as a time server supporting the SNTP and Daytime
protocols and can be used to synchronize computers or other devices via the Ethernet.
To set up your computer or other device to synchronize to the SiteSync IQ Remote Transmitter, simply enter the IP address of
the Remote Transmitter as the time server address for the computer or device.
In Windows XP:
1. Right-click your clock and then click
Adjust Date/Time
.
2. Click the
Internet Time
tab. click the
Server
down arrow, and then enter the IP address of the Remote Transmitter you
wish to synchronize this computer to (example: 192.168.1.200).
3. Click
Update Now
. Windows XP will connect to the Remote Transmitter and set the computer's clock.
In Windows 7:
1. Right-click your clock and then click
Adjust Date/Time
.
2. Click the
Internet Time
tab, and then click
Change Settings
.
3. Check
Synchronize with an Internet time server
, enter the IP address of the Remote Transmitter you wish to synchronize
this computer to (example: 192.168.1.200), and then click OK.

Important Notes:
• Setting up your computer to synchronize to the Remote Transmitter via Ethernet does not account for time zone and
Daylight Saving Time settings, which must be properly set on the computer (they are not transferred via Ethernet).
• The computer or other device being synchronized to the Remote Transmitter must be on the same network as the
Remote Transmitter, or have access to it through a firewall (port 123 open for SNTP and port 13 open for Daytime
Protocol).
• If your computer is on a domain, it is set up to get the time from the domain controller and you will not be able to
perform the above tasks. Domain controllers using the Windows Time Service can be set up by your network administrator
to synchronize directly to time servers on the Internet or to the Remote Transmitter. Contact American Time Technical
Support at 866-748-3796 with any questions.
Tip: Choose the time server closest to you.

Note:
Please reference http:/tf.nist.gov/tf-cgi/servrs.cgi for the latest NIST Internet Time servers list, which includes the
status of each server.
