3: Installation/Configuration
ENTER (5 times) Displays “SAVE CHANGES – YES”
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 page202) 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 page84) 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.
