Starting Up & Shutting Down
Revision R09, November 2016 29
7.2 Starting up with LAN connection
Additionally or instead of the RS 485 connection a LAN connection (Ether-
net) can be used.
Precondition: LAN cable is connected (see chapter 6.2)
Configuration: 3 IP addresses are available at the same time for communication:
1. a pre-configured fixed service address to the CHM 15k Nimbus
–
192.168.100.101 , Subnet 255.255.255.0
2. DHCP server allocation (DHCP server required)
3. user a gateway (see chapter 8.7 for configuration with
TCP/ IP access to the instrument and chapter 8.1 and 8.2 if you configure
these values using the RS485 interface)
The service address (1) can not be modified by the user. It is always available and
can be used for direct connections between a laptop and the CHM 15k Nimbus.
The address (3) can be entered in a web browser window (Fig. 13) to communi-
cate with the instrument. Fig. 17 shows the “Config Network” tab in the Firefox
web browser. Superuser authorization is required to change the user IP address
(3).
Super user password: 15k-Nimbus
The web interface was tested with the following web-browsers:
l
Internet Explorer 8 or newer
l
Firefox 3.6 or newer
l
Google Chrome
l
Apple Safari
In DHCP (2) network environments the CHM device is automatically configured.
The DHCP mode can be switched off.
A port scan utility can help to identify the IP address. Another comfortable way
is to use the RS485 connection and poll the device for the DHCP IP address by
entering:
get<SPACE><RS485No>:IPD<CR><LF>.
If available, the instrument will submit the DHCP address that can be used in a

(here with a fixed address).
