SERIAL NUMBER
If you press the SET key, the display's serial number is displayed; it is significant for the
programming of messages: your must enter it while working with the message-programming program
(see the chapter on the programming of messages). The number is written also at the display's rear;
it can not be altered.
TIME ZONE
Within this menu, you can set the difference between the local time and the UTC. You can set the
algebraic sign, the hours and the minutes. The display calculates the local time according to the
formula: local time = UTC + the difference. For Central Europe, the difference amounts to +01:00 for
the standard time, and +02:00 for the Daylight Saving Time. If you wish to display the UTC time, set
both values to +00:00.
WINTER/SUMMER, SUMMER/WINTER
Here you can set the date and the hour of the automatic transition from the standard time to the
Daylight Saving Time (Summer Time) and vice versa.
You can set the exact transition moment for the current year, or universally
– for several years. In the
case of the universal setting, you set a day of the week and a date containing two asterisks ('**') in
place of the year. The transition will happen when the chosen day of the week comes for the first
time, provided the then date is later than the one set or equal to it.
Example:
In Central Europe, the transition is put into effect on the last Sunday in March, at 02:00:00 AM (local
time). The universal (default) setting is: SUN 25.03.** 02:00:00.
The transition from the Daylight Saving Time to the standard time is put into effect on the last Sunday
in October. The universal (default) setting is: SUN 25.10.** 03:00:00.
On the other hand, the settings valid only for the year 2005 are the following:
*** 27.03.05 02:00:00 and *** 30.10.05 03:00:00.
With these settings, next year it will be necessary to set the transition times anew.
IP ADDRESS, SUBNET MASK, DEFAULT GATEWAY
The display's IP address, subnet mask, and default gateway are set in accordance with the data of
the existing network to which you intend to connect the display.
A DHCP client is integrated in the display, which can set alone in relation with a DHCP server (if
provided in the network) all the proper network settings. The DHCP client is activated if
“DHCP: Y” is
chosen. If “DHCP: N” is chosen, the client is switched off and all the network settings should be set
manually.
If DHCP is switched on, then
menus »subnet mask« and »default gateway« can only be inspected
but not changed.
NTP SERVER 1, NTP SERVER 2, NTP SERVER 3
Using the SNTP protocol, the display can set its internal clock automatically. For this purpose, it must
have access to the NTP time server. In these menus, IP addresses of up to 3 NTP servers can be
set. The display is synchronized by the first available server. A setting
“0.0.0.0” means that the server
is not set.
TIME FORMAT
In newer versions it
’s possible to display time in various formats. In this menu you can choose
between two formats:
