GPS Menu
The GPS menu shown below allows you to monitor the GPS status and set the parameters for UTC
Offset and Automatic Daylight Saving Time controls for Models 7400 and 9400 that have the optional
7400-GPS Option installed.
• GPS Status – Possible values are: Normal Operation; No Satellites; Antenna Open; Antenna
Shorted, Not Installed.
Normal Operation – the GPS function is operating normally.
No Satellites – This may indicate that the Avenue module is still in the process of
establishing a connection to the satellites. When first setting up the GPS functionality, it is
normal for the process to take up to one hour to establish proper satellite connections.
Antenna Open – This status means that there is a loose cable connection, either between
the 7400 module and the GPS sub-module, or between the 7400 or 9400 and the antenna.
Make sure that you have installed the GPS submodule properly and installed the H1 jumper
in the GPS position. Check the GPS sub-module connections as well as the connections to
the antenna to make sure that everything is connected properly. See the “7400-GPS Option
Field Installation Procedure” on page 17 for more information.
Antenna Shorted – This indicates that there is a short somewhere between the Avenue
Frame and the antenna.
Not Installed – The GPS sub-module is not installed on the Avenue 7400 or 9400 module.
• UTC Offset – The UTC Offset is used to configure Models 7400 and 9400 so that the time that is
loaded into the timecode generator from the GPS is properly offset to the local time zone. The
UTC in the 7400 or 9400 module follows the North American practice.
The UTC Offset available menu options are -12 to 12, offset in hours. As an example, the setting
for the Pacific Time Zone in North America (Los Angeles) is an offset of -8
Note: UTC stands for Coordinated Universal Time, formerly known as GMT (Greenwich Mean
Time)
• Auto DST – Turn this feature On or Off.
When the Auto DST function in On, timecode will automatically be adjusted forward by an
hour in the spring and back by an hour in the fall. If you want this auto functionality, leave the
Auto DST function On all year round.
If you want to adjust for Daylight Saving Time manually, turn the Auto DST function Off and
change the UTC by one hour manually on the designated dates in the spring and fall.
Note that the calendar rules used for the beginning and ending of Daylight Saving Time by
the 7400 GPS Option are based upon the practice in North America.
