IP Address
The GXV300x operates in two modes:
•
DHCP mode: all the field values for the Static IP mode are not used (even though
they are still saved in the Flash memory.) The GXV300x acquires its IP address
from the first DHCP server it discovers on its LAN. The DHCP option is reserved for
NAT router mode (currently NOT implemented).

Time Zone
This parameter controls the date/time display according to the specified time zone.
The “Allow DHCP Option 2 to override Time Zone setting” option allows DHCP server to

The “Allow DHCP Option 2 to override Time Zone setting” option allows DHCP server to

Daylight Savings Time
This parameter controls time displayed in daylight savings time. If set to “Yes”, then the dis-
played time will be 1 hour ahead of normal time.
The “Optional Rule” is configured to automatically adjust the Daylight Savings Time (DST)
based on the rule set in this field.
Rule Syntax:
played time will be 1 hour ahead of normal time.
The “Optional Rule” is configured to automatically adjust the Daylight Savings Time (DST)
based on the rule set in this field.
Rule Syntax:
•
start-time; end-time; saving
•
Both start-time and end-time have the same syntax: month,day,weekday,hour,minutes
o
month: 1,2,3,..,12 (for Jan, Feb, .., Dec)
o
day: [+|-]1,2,3,..,31
o
weekday: 1, 2, 3, .., 7 (for Mon, Tue, .., Sun), or 0 which means the daylight
saving rule is not based on week days but based on the day of the month.
saving rule is not based on week days but based on the day of the month.
o
hour: hour (0-23), minute: minute (0-59)
If “weekday” is 0, it means the date to start or end daylight saving is at exactly the given date.
In that case, the “day” value must not be negative. If “weekday” is not zero and “day” is posi-
tive, then the daylight saving starts on the first “day” the iteration of the weekday (e.g.: 1st
Sunday, 3rd Tuesday etc). If “weekday” is not zero and “day” is negative, then the daylight
saving starts on the last “day” the iteration of the weekday (e.g.: last Sunday, 3rd last Tues-
day etc).
The saving is in the unit of minutes. The saving time may also be preceded by a negative (-)
sign if subtraction is desired instead of addition.
The default value is set for US, the “Automatic Daylight Saving Time Rule” shall be set to
“3,2,7,2,0;11,1,7,2,0;60”
Examples
US/Canada where daylight saving time is applicable:
03,02,7,02,00;11,1,7,02,00;60
This means the daylight saving time starts from the second Sunday of March at 2AM and
ends the first Sunday of November at 2AM. The saving is 60 minutes.
In that case, the “day” value must not be negative. If “weekday” is not zero and “day” is posi-
tive, then the daylight saving starts on the first “day” the iteration of the weekday (e.g.: 1st

saving starts on the last “day” the iteration of the weekday (e.g.: last Sunday, 3rd last Tues-
day etc).
