ENTER Saves the new network parameters, and reboots the XL-GPS
Notes:
To prevent remote network access to the XL-GPS, change Remote Lockout to
LOCK. Doing this shuts down remote access through the XL-GPS’s network port so
that the XL-GPS’s functions are available only through the keypad interface, and
through the serial port’s command line interface.
For additional information, consult the relevant topics covering the F100 commands.
Configuring the Time Display
Configure the XL-GPS to display time correctly. Use the menu-driven keypad interface, to
enter the functions and select the desired settings, as follows:
F1 Time Zone Offset: (“F: World Map of Time Zones:” on page202) Set the
number of hours difference between your time zone and UTC. For example:
- Pacific Standard Time is UTC -08:00
- Mountain Standard Time is UTC-07:00
- Central Standard Time is UTC -06:00
- Eastern Standard Time is UTC-05:00
F2 12/24-Hour Format: (“F2 12/24 Hour Format on page50) Select a 12 or 24-
hour display format. By default, the XL-GPS is set to the 24-hour display format (e.g.,
6 P.M. is displayed as 18:00).
F66 Daylight Saving Time (DST): (F66 Daylight Saving Time (DST) Mode
on page84) If needed, set when Local time enters and leaves DST.
- The factory settings for F66 apply to most users in the continental US: DST
begins at 2 A.M. on the 2
nd
Sunday of March, and ends at 2 A.M. on the 1
st
Sun-
day of November.
- DST is NOT observed in Hawaii, American Samoa, Guam, Puerto Rico, the Vir-
gin Islands, the Eastern Time Zone portion of the State of Indiana, and most of
Arizona (Navajo Indian Reservation observes DST).
- Throughout the European Union (EU), Summer Time begins and ends at 1 A.M.
UTC. It starts the last Sunday in March, and ends the last Sunday in October. In
the EU, all time zones change at the same moment.
F69 Time Mode: (“F69 Time Mode on page90) Select the type of time output on
the front panel display, F8, and F90. The four choices are as follows:
- UTC (Coordinated Universal Time) differs from GPS Time by the addition of
leap-second corrections to compensate for variations in the earth’s rotation.
