Bar Code Port
The use of barcodes in the laboratory has become
a highly accurate, rapid and inexpensive way to
identify samples. When purchasing this feature,
the user must supply Parr with the MAC address of
the calorimeter (found in the Software & Hardware
Info menu screen). This allows Parr to activate the
feature key. In order to enable the calorimeter to
use the bar code feature, the feature key needs to
be entered into the instrument. Select the “Program
Information and Control” key from the Main Menu.
Next, select “Feature Key” and enter the feature key
purchased from Parr Instrument Company into the
instrument by using the touchpad. Pressing the key
labeled “ABC” allows the user to switch from up-
per case letters, to lower case letters and fi nally to
numerals. A CD containing all the necessary docu-
mentation and setup information for using both the
scanner and the printer is provided at the time of
purchase. A PC based program used for printing bar
coded labels is also provided on this CD.
Computer Connections
If the 6772 Calorimetric Thermometer is to be con-
nected to a computer, the Ethernet connection
should be used. Calorimetric Thermometer 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 Calorimetric Thermometer.
The network DHCP (Dynamic Host Confi guration
Protocol) server provides this address shortly after
the Calorimetric Thermometer is turned on. The ad-
dress can be seen on the Software & Hardware Info”
screen, under Program Info and Control Menu; see
the example screenshot. Users who don’t have a
network infrastructure can create a simple network
by connecting a router with DHCP server capability
to the Calorimetric Thermometer using an ordinary
CAT 5 network cable. The Calorimetric Thermometer
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 pri-
mary 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 confi gurations. An FTP enabled web browser
can be used to access stored test data. The URL is
of the following form:
Test Data:
ftp://root:[email protected]/../fl ash/data/
Data Log:
ftp://root:[email protected]/../fl ash/log/datalog.csv
In this case, 192.168.0.125 is the IP address of the
Calorimetric Thermometer.
