TABLE 8: DEVICE CONFIGURATION DEFINITIONS

By default, HTTP uses port 80 and HTTPS uses port 443. This field is for customizable web
port.
End User
Password
This contains the password to access the Web Configuration Menu. This field is case sensi-
tive with a maximum length of 25 characters.
IP Address
The GXV-3000 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 GXV-3000 acquires its IP address
from the first DHCP server it discovers on its LAN. The DHCP option is reserved for
NAT router mode.
• To use the PPPoE feature, set the PPPoE account settings. The GXV-3000 estab-
lishes a PPPoE session if any of the PPPoE fields is set.
• Static IP mode: configure all of the following fields: IP address, Subnet Mask, De-
fault Router IP address, DNS Server 1 (primary), DNS Server 2 (secondary). These
fields are set to zero by default.
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” give DHCP server to overwrite
default NTP time server if uses have own NTP server. Default is No.
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:
• start-time;end-time;saving
• Both start-time and end-time have the same syntax:
• month,day,weekday,hour,minute
• month: 1,2,3,..,12 (for Jan, Feb, .., Dec)
• day: [+|-]1,2,3,..,31
• 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.
• 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” th 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”th iteration of the weekday (last Sunday, 3rd last Tuesday 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.
