The web interface was tested with the following web browsers:
•
Internet Explorer 8 or later

In the DHCP (2) network environment, the CHM 15k is configured automatically. The DHCP mode can
be switched off.
Figure 15 Firefox browser for a connection with the CHM 15k (shown here with fixed IP address).
It is possible to use the RS485 connection and query the DHCP IP address by entering:
get<SPACE><RS485Number>:IPD<CR><LF>.
If available, the device transmits the DHCP address that can be used in a second step in a web
browser to connect to the system via a LAN connection.
The user IP address can be set or queried by the user via RS485, too, using the parameter IPS instead
of IPD, e. g.:
get<SPACE><RS485Number>:IPS<CR><LF>
set<SPACE><RS485Number>:IPS=xxx.xxx.xxx.xxx<CR><LF>
For further support regarding communication please contact G. Lufft GmbH.
7.3 Shutdown
Advanced users should carefully disconnect the device from the power supply:
Users with superuser authorization should use the web interface: Log in as a superuser and
press "SHUTDOWN SYSTEM" on the device tab
RS485 users can enter the following command:
set<SPACE><RS485Number>:SHT<CR><LF>
In both cases the Linux-based system is turned off and measurement data are stored on the
local SD card.
After the soft shut down the main power can be disconnected without the risk of data loss.
To uninstall the CHM 15k and reinstall it at a different location, carry out the steps described
in sections 6.1.2 Installing on the foundation and 6.2 Electrical installation in reverse order.
