Conclusion
By carefully following the instructions in this Section (including the Appendix, if you
are connecting via direct serial cable or modem), you should have successfully in-
stalled the necessary Windows services and connected to your 8600. (Note that
Ethernet connections are preferred because they are easier to configure than serial
connections and are faster.) However, if you experience any problems with this pro-
cess, or have any other 8600 questions, please contact Orban Customer Service:

Synchronizing Optimod to a Network Time Server
[Skip this section if you do not wish to automatically synchronize your Optimod’s
internal clock to a network timeserver, which may be part of your local network or
located on the Internet.]
1. From the main menu, Locate to System Setup > Place/Date/Time > Time
Sync.
A) Use the
S
YNC
P
ROTOCOL
control to choose either
T
IME
P
ROTOCOL
or
SNTP.
•
Select Time Protocol if the Optimod is behind a firewall that does not pass
UDP packets. Time Protocol selects the Time Protocol as described in the
standard RFC868. This method uses TCP on port 37.
•
Select SNTP if your network timeserver supports the Simple Network Time
Protocol as described in standard RFC1769. This method uses UDP on port
123.
Ask your network administrator which protocols are available. SNTP is
slightly more accurate.
B) Locate to
S
YNC
P
ERIOD
. Using the knob, choose how often your Optimod will
automatically update its internal clock to the timeserver you selected.
The choices are
O
FF
,
8
HOURS
, and
24
HOURS
.
If the connection to the timeserver fails (due to network overload or other prob-
lems), your Optimod will try once per hour to synchronize until it is successful.
C) Locate to
O
FFSET
.
Using the knob, set it to the difference (in hours) between
your time zone and Universal Time (UTC).
UTC is also known as GMT, or Greenwich Mean Time.
