DU35S as Stand Alone Clock
After connecting the mains power the shown time can be set by the two buttons in the
rear panel of the case. The accuracy of the time depends on the precision of the
internal quartz base.
An automatic changeover of daylight saving can be programmed as described in
section "Daylight Saving".
DU35S as Slave Clock
The DU35S can be synchronized by a preconnected radio clock that sends time strings
periodically. When the radio clock stops sending time strings the DU35S continues by
running on XTAL.
The data transmission occurs either:
- via RS232 or
- via 20mA current loop.
It is possible to connect several DU35S' or other similar displays via series
connection to one radio clock.
Usage of the Buttons MENU and SET
The time and date, the language, the brightness, the serial parameters and the automa-
tic changeover of daylight saving can be edited by using the buttons MENU and SET.
The button MENU is used to change over from the normal operation mode into the
'set parameters' mode and to select the different menus. The button SET is used to
modify the selected parameter. When leaving the menu by pushing MENU the
modification is acknowledged. When no button is pushed for more than 30 seconds
the DU35S goes back into normal operation mode with loosing the last modification
that was not acknowledged. The menus in detail are described below.
