Balance Handler Strings. This key leads to
a submenu that allows balance template
to be customized for unique balances or
needs.
t
Log Balance to Display. Directs the incom-
ing data stream from the balance to a display
buffer. This function can be used to deter-
mine the data format from an unknown bal-
ance type. The display buffer is 40 characters
in length. The balance must be forced to is-
sue at least 40 characters before the contents
of the buffer are displayed.
t
Balance Port LoopBack Test. Initiates a
loopback test on the port. A special loopback
plug is required in order to perform this test.
Further information on establishing
communications for the Printer, Balance, Network
Interface, Bar Code and other Network Data Devices
can be found in the
Installation section and Data
and Communication Specifi cations section of this
manual.
Network Interface
The test data can be transferred to an Ethernet
network connected computer using the FTP File
Transfer Protocol. First you must know the IP ad-
dress of the network-connected Proximate Interface.
The network DHCP (Dynamic Host Confi guration
Protocol) server provides this address shortly after
the unit is turned on. The address can be seen on
the “Software and Hardware Info” page within the
“Program Information & Control” menu.
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 ordinary CAT 5 network cable. The unit should be
connected to the 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 connec-
tion, 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. Pro-
viding an active upstream connection to the WAN
port of most routers generally minimizes the use of
any obscure setup confi gurations.
The Proximate Interface also supports the use of
a static IP address. A static IP address can be as-
signed from the Network Interface page under Com-
munication Controls.
An FTP enabled web browser can be used to
access stored test data. The URL is of the following
form:
ftp://[email protected]/../fl ash/data/
In this case, 10.1.5.32 is the IP address of the
Proximate Interface.
