LOYTEC  

Version 3.1 

 

LOYTEC electronics GmbH   

4.3.9  Option 0 – Reset Device 

Select this menu item to reboot the L-Proxy. Some configuration changes require rebooting 
the device. Note that this option does not reset the configuration. 

4.3.10  Option a – Data Points 

This menu option takes the user to the data point menu. In this menu, the configured data 
points in the L-Proxy can be viewed and set. See Section 4.10 for details. 

4.4  System Configuration Menu 

The system configuration menu holds various system configuration settings. Typically, the 
system configuration menu looks like shown in Figure 12. 

System Configuration Menu

4.4.1  Option 1 – Configure Date/Time 

This menu item allows configuring L-Proxy’s system time. It provides several sub-items as 
shown in Figure 13. With menu option 

1

, the time source is defined. The following options 

are available: 

auto

, 

manual

, 

NTP

, 

LonMark

. In the 

auto

 mode, the device switches to the 

first external time source that is discovered. The option 

manual

 allows setting the time 

manually using menu items 

2

 and 

3

. In 

manual

 mode, the device does not switch to an 

external time source. Note that if 

NTP

 is selected, the NTP servers have to be configured in 

the IP setting menu (see Section 4.3.5). 

Date/Time Configuration Menu 
============================ 
 
[1]  Set time sync source: manual 
[2]  Set date            : 2008-01-29 
[3]  Set time            : 10:58:56 
[4]  Set timezone offset : +01:00 
[5]  Set DST             : none 
 
[q]  Quit without saving 
[x]  Exit and save 
 
Please choose: 

Figure 13: Configure Date/Time Menu 

The time zone offset must be defined independently of the time source. It is specified in 
menu option 

4

 and defines the offset to GMT in hours and minutes (e.g., Vienna/Austria is 

+01:00, New York/USA is –06:00). Start and end of daylight savings time (DST) is 
defined in menu option 

5

. Predefined choices are offered for Europe and USA/Canada. 

DST can be switched off completely, or set manually for other regions.
