Computer Connections
If the 6400 Calorimeter is to be connected to a
computer, the Ethernet connection should be used.
Test data can be transferred to an Ethernet network
connected computer using the FTP File Transfer
Protocol. First, you must know the IP address of
the network-connected calorimeter. The network
DHCP (Dynamic Host Configuration Protocol) server
provides this address shortly after the calorimeter is
turned on or a static IP address can be assigned. The
address can be seen on the “Software & Hardware
Info” screen, under Program Info and Control Menu
(see the example screenshot on page 41). Users
who don’t have a network infrastructure can create
a simple network by connecting a router with DHCP
server capability to the calorimeter using an ordi-
nary CAT 5 network cable. The calorimeter should
be connected to LAN side of the router. The PC in
turn is also connected to the LAN side of the router
using a similar CAT 5 cable. A D-Link 614+ router
is recommended for this purpose. For this router,
operated without a WAN connection, the primary
DNS address of the router (WAN setup) must be
set to the IP address of the router found on the
LAN setup page. Other routers behave differently
in the absence of a WAN connection. Providing an
active upstream connection to the WAN port of most
routers generally minimizes the use of any obscure
setup configurations. An FTP enabled web browser
can be used to access stored test data. The URL is
of the following form:
ftp://root:[email protected]/../flash/data/
The datalog file can be accessed at:
ftp://root:[email protected]/../flash/log/
datalog.csv
In this case, 192.168.0.125 is the IP address of the
calorimeter.
The following screenshot illustrates the contents of the calorimeter data directory as presented by a web browser.
You can drag and drop or copy and paste test data files (with the csv suffix) from the web browser window
to any convenient folder or directory on the PC.
