2. Choose a timeserver.
http://tf.nist.gov/tf-cgi/servers.cgi
provides a current list of timeservers available
on the Internet. You network may also have a local timeserver; ask your network
administrator.
3. Set up timeserver parameters.
You can specify the timeserver either from your Optimod’s front panel or from
its PC Remote software. From the front panel, you can only enter the time-
server’s IP address (for example, 192.43.244.18). If you specify the timeserver
from PC Remote, you can specify either its named address (for example,
time.nist.gov) or its IP address.
4. Specify the time sync parameters from your Optimod’s front panel:

from your Windows XP computer.]
A) L
OCATE
to the S

ERVER
button and press E
NTER
.
a) L
OCATE
to C
LEAR
. Then press the E
NTER
button.
This will allow you to enter the IP address of the desired timeserver.
b) Use the L
OCATE
button, toggle to the first number and then press the
E
NTER
button; repeat until you have selected all the numbers in the IP ad-
dress. When the IP address entry is complete, toggle to
S
AVE
and press the
E
NTER
button.
B) L
OCATE
to the S
YNC
N
OW
field and press E
NTER
to test your settings. Your Op-
timod’s display should indicate that it is connecting to the IP address that you
specified. When the connection is successful, the Optimod’s clock will auto-
matically synchronize to the timeserver.
•
If the connection is not successful within five seconds, the display will indi-
cate that the connection failed. This means either that the timeserver is too
busy or that your setup cannot connect to the timeserver. Double-check the
IP address. If you are behind a firewall, make sure that port 123 is open.
•
If your connection failed, the gateway address might not be set correctly
on your Optimod. The gateway address for the timeserver connection is the
same gateway address that you set in step (1.C) on page 2-56. If you do not
know the correct gateway address, you can often discover it by connecting
a Windows computer to the same Ethernet cable that is ordinarily plugged
into your Optimod. Ascertain that the computer can connect to the Inter-
net. At the command prompt, type
ipconfig
. The computer will return
the “Default Gateway.”
5. Specify the time sync from the Optimod PC Remote software:
