Scope
This manual contains instructions for installing
and operating the 6750 Proximate Interface.
The 6750 Proximate Interface can be installed in
a variety of confi gurations and the user will want to
choose the proper installation procedures for his or
her planned setup. Each 6750 Proximate Interface
is equipped with two USB ports and an Ethernet network connection.
Normally, the USB printer connection will be
used in conjunction with a standalone printer. The
1758 Printer can be used with the 6750 Proximate
Interface. A cable to connect the 6750 Proximate
Interface to the 1758 Printer is supplied
with the printer.
The USB port is also used to accept sample
weights directly from an analytical or top-loader
balance. The Interface software has been confi gured
to operate with a wide variety of balances. Parr can
supply cables for common balance connections.
An Ethernet network connection is used when
the 6750 Proximate Interface will be installed in
conjunction with a calorimeter and / or ADL or total
moisture interface devices. It may also be chosen
when longer distance communications are required.
Separate sections of this manual deal with each of
these communication ports.
Concept of Operations
The 6750 Proximate Interface is an advanced
microprocessor system designed to:
t Collect and store all individual weights obtained
during the series of steps required to determine
moisture, volatile matter, ash, Btu’s and Sulfur
for up to 1000 coal samples, with all data identifi ed by a user assigned alphanumeric sample ID
string (16 characters).
t Collect and store sample weights for Btu deter-
minations.
t Coordinate and organize all data as it becomes
available, and store it in correct order without
regard to entry sequence.
t Calculate the resulting proximate analysis for
each sample on any of four reference bases:
As-determined (AD)
As-received (AR)
Dry (DRY)
Dry, ash-free (DAF)
t Convert and report Btu and sulfur values to se-
lected moisture reference bases.
t Act as a remote Air Dry Loss or Total Moisture
Interface.
t Support data entry, storage and reporting for
two additional types of coal tests commonly
done in the same laboratory along with the
more traditional mass loss or calorimetric based
measurements.
t Free swelling index (FSI)
t Ash Fusion
t Transmit all results to a network printer, and/or
to a 40 or 80-column printer, and/or to a central
computer to obtain a consolidated printout or
report of the proximate analysis, Btu and sulfur
values for each sample.
t Produce fi nal or preliminary reports at any time
for any valid sample ID.

Proximate Interface
Preface (Continued)
The 6750 Proximate Interface does not require
a special oven, furnace or analytical balance. All
drying and ashing operations are performed in the
same oven and furnace normally used for standard
ASTM proximate analyses. The 6750 Proximate
Interface is designed to communicate with a Mettler,
Sartorius, Ohaus or most digital analytical balances
for automatic data entry. Sample weights can also
be entered manually using the touch screen keyboard on the console.
Existing laboratory procedures do not have to
be changed. Samples can be weighed and treated in
any order, with the 6750 Proximate Interface accepting data from a digital balance as generated, organizing and storing it in the correct order, under operator assigned sample IDs. The operator can override
the automatic data entry system at any time to enter
weights as percentage values, manually if necessary. Weights used to determine air-dry loss (ADL)
or total moisture can be entered manually, or the
ADL or total moisture value can be calculated and
entered separately as a percent.
Usually the 6750 Proximate Interface will be
installed adjacent to an electronic analytical balance
and connected to the Interface with a serial communications cable. After each weighing, the entry will
be shown on a LCD display of the 6750 Proximate
Interface for confi rmation before it is entered into
memory. The operator will then use the touch screen
keyboard to identify each entry test (moisture, ash,
volatile matter, Btu or air dry loss) or function (tare,
gross or fi nal weight) to which the data applies.
The 6750 Proximate Interface will also prompt the
operator to identify each entry with a valid sample
ID. Several selectable options are available to speed
data entry procedures by allowing the operator to
enter consecutive tare and gross weights automatically with a minimum number of keystrokes. Data
for up to 1000 samples can be entered before results
must be withdrawn to make room for additional
data. All data is stored in non-volatile Flash ROM
based memory.
Additional 6750 Proximate Interfaces may be
connected to the network confi gured as ADL or total
moisture interface devices at some remote location.
In this system, the primary 6750 Proximate Interface
can then be confi gured to get ADL or total moisture
data (weights) from the remote 6750 Proximate
Interface, confi gured as an ADL or total moisture
device.
If the 6750 Proximate Interface is connected to
a Parr Calorimeter via an Ethernet communications
network, sample weights for heats of combustion
determinations will be transferred automatically to
the calorimeter. Determined Btu and Sulfur values
can then be transferred back to the 6750 Proximate Interface for incorporation in fi nal reports. If
the 6750 Proximate Interface is not connected to a
calorimeter controller, Btu and Sulfur values can be
entered directly through the touch screen.
The user can select from a variety of pre-programmed options to obtain either complete or partial reports for individual samples or for a full range
of tests. A memory management system will clear
the test report memory when desired.

Installation
This apparatus is to be used indoors. It requires
at least 2 square feet of workspace on a sturdy
bench or table in a well-ventilated area with convenient access to an electric outlet. The supply voltage
must be within ± 10% of marked nominal voltage on
the apparatus. The supply voltage receptacle must
have an earth ground connection.
Balance Port Connections
The balance driver software in the 6750 Proximate Interface has been confi gured to operate with
a wide variety of balances. The following three balance protocols are supported:
1. Mettler
2. Sartorius
3. A & D
A fourth “generic” protocol is provided which
may, in many cases work with other balances that
are not directly supported. The user should fi rst
study the input specifi cation of the generic format
for compatibility with the intended balance if it is
not one of the fi rst three protocols listed above.
Other balances may be supported if their output
formats are compatible with the above four balances or a generic format which is supported by the
6750 Proximate Interface. Parr can supply the cables
for the balance port to balance connection. The
cables are listed in the
chapter of this manual.
Balances with an RS232C output will need to use
the 2203E RS232 to USB converter.
Data and Communications
be transferred to an Ethernet network connected
computer using the FTP File Transfer Protocol. By
default, the network interface is turned off. The
Interface can be confi gured to use DHCP (Dynamic
Host Confi guration Proticol) or have a static or fi xed
IP address. It is recommended, that any network
confi guration parameters only be set or altered after
consulting with your network administrator. Further

Installation section and Data
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 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 confi gurations.
The Proximate Interface also supports the use of
a static IP address. A static IP address can be assigned from the Network Interface page under Communication Controls.
An FTP enabled web browser can be used to
access stored test data. The URL is of the following
form:
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 address 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.
ftp://root.rootroot@10.1.5.32/../fl ash/data/
In this case, 10.1.5.32 is the IP address of the
Proximate Interface.

Operating Instructions
Data Entry & Operation
There is a basic method for identifying and entering sample weight data into the 6750 Proximate
Interface. Settings are available through the Data
Entry Controls page to speed this process in the following situations.
t When consecutive Sample IDs are used.
t When gross and tare weights are entered con-
secutively.
t When only net weights are entered for Btu deter-
minations.
t When results are entered as percentages.
t When the same sample is used for both mois-
ture and ash determinations.
22
For dealing with these unique situations, the operator should be familiar with the data entry procedure, which is identical for air dry loss, total moisture, residual moisture, ash, volatile matter, sulfur,
Btu weights and/or values.
Parr Instrument Company
Page 24
Proximate Interface
Basic Data Entry Procedures
Pressing the SAMP ID key starts the data entry
sequence. This will prompt the operator to enter
the sample identifi cation string through the touch
screen (up to sixteen characters permitted). Next,
the operator presses the test identifi cation key,
MOIST, ASH, VM to identify the test followed by the
weight identifi cation key, TARE, GROSS, FINAL that
identifi es the weight. More than one weight identifi cation key can be selected. Most procedures call for
pressing both the tare and gross key initially.
The Interface will prompt for the tare weight of
the crucible followed by the gross weight. All this
time the Sample ID number and the selected test
and weight type(s) will be displayed. Once these
are verifi ed, the operator presses the ENTER key to
enter this identifi cation information. The display will
prompt the operator for weight information with a
prompt.
BTU Weight Entry
The 6750 Proximate Interface can be used as a
balance interface device to enter and store sample
weights for calorimetric tests. The weight entry process uses the BTU test identifi cation key followed
by pressing the gross key. Alternately the Date Entry
Controls page can be set to prompt for the tare
weight for those balances that do not have an automatic tare function.
BTU & Sulfur Value Entry
Btu and Sulfur values may be retrieved from
calorimeters or manually entered through the touch
screen. Entries on the Data Sources page controls
this choice. To enter these values, press the SAMP
ID and enter the sample identifi cation number.
Press the BTU or Sulfur key followed by ENTER. In
the retrieval mode, the appropriate value will be
transferred from a calorimeter to the display of the
Interface.
Weights are automatically transferred from the
balance when confi gured by pressing the <TRANSFER> key or they can be entered manually through
the keypad. The value can be verifi ed by the operator and entered into the 6750 Proximate Interface by
pressing the ENTER key, unless the automatic store
feature has been enabled. The basic weight entry
process is complete and can be repeated for the
next sample or weight. Moisture, ash, and volatile
matter can also be entered as percentages from the
keyboard by pressing the SAMP ID key, entering the
sample number, followed directly by ENTER which
causes a prompt for the percent value to be entered.
Once verifi ed, this value can be entered into the
Interface by pressing ENTER. If Btu values in the calorimeter or controller are preliminary values, then
any Btu or Sulfur values found by the Interface will
not be accepted. In the manual mode the operator
simply keys in the value in response to the prompt.
Btu and Sulfur values should be entered into the
Interface as “as determined values”.
www.parrinst.com
23
Page 25
Proximate Interface
Air Dried Loss or Total Moisture Entry
Air Dried Loss (ADL) or Total Moisture (TM)
weights are identifi ed with the corresponding key. A
report fi le can contain ADL or TM data but not both.
Entering one kind of data excludes the other from
being entered unless the other is cleared by editing
the report. The total moisture value is numerically
equal to moisture as received.
Settings on the Data Entry and Controls page
determine the ADL and TM prompting order for
data entry. Users having a second 6750 Proximate
Interface confi gured as an ADL or TM Interface may
obtain these data from the remote interface via the
Ethernet port. Settings on the Data Entry and Controls page control the source of the ADL or TM data.
The procedure for obtaining the ADL or Total
Moisture Weights from a remote interface is the
same as a manual entry procedure. To expedite
ADL or TM weights from a remote device, the recommended procedure is to press all three weight
identifi cation keys (TARE, GROSS and FINAL) before
the enter key when obtaining weights from a remote
6750 ADL or TM Interface. No information will be
sent, even if only one datum is requested, unless
all three weights have been entered into the remote
interface.
Ash Fusion Entry
Ash Fusion values are identifi ed with the corresponding keys. The user can choose either Ash
Fusion Oxidizing or Ash Fusion Reducing. Once this
choice is made the following four critical point temperature keys are displayed.
t IT, Initial deformation temperature
t ST, Softening temperature
t HT, Hemispherical temperature
t FT, Fluid temperature
Any number of these keys can be pressed. The
Interface will then prompt for the corresponding
value(s). Typical values for this test range from 1470
F (800 C) to 2900 F (1600 C). Values are reported to
the nearest unit. The reporting units, degrees C or F,
for the critical point temperatures is set on the Data
Entry and Controls page.
FSI Entry
Pressing the FSI key will simply initiate a prompt
for a numerical value for the free swelling index of
the sample, displayed to the nearest tenth of a unit.
The typical range of values is zero to 12.
Automatic Sample ID Increment Option
The basic data entry procedure can be modifi ed
to streamline the entry of data, and to adapt it to the
individual user’s operation procedures. One method
of modifying these procedures is through the use
of the Auto Sample ID Controls. When this option is
turned on, the Interface will automatically increment
the Sample ID by the value indicated on the Auto
Sample ID Controls page and prompt for a new set
of values each time a data entry sequence is completed.

wish to edit a batch list.
Play, Stop:
When batch list Play is selected and the batch list is
empty, a warning dialog is displayed and the batch
mode stays in the prior state. When a Sample ID
would normally be prompted for the next ID in the
batch list is displayed. When the end of the batch
list is encountered the batch mode is returned to the
Idle state.
Record, Stop:
When Record is selected all subsequent sample ID
entries are appended tot he end of the currently
selected list. Recording continues until the user
presses the stop button.

Upload:
The Upload button is used to upload copies of the
currently selected batch list to all devices specifi ed
in the network data device lists. The Upload button
is disabled when the batch list is on record mode.
Erase:
To completely erase a batch list press Erase with
batch list selected. You will be prompted to confi rm
this operation.

Balance Input Driver Specifi cations
Overview
The 6750 Proximate Interface supports input
from the three balance types indicated below. Additionally, a generic input driver is provided for
communications with balances that do not conform
to the directly supported protocols. A feature supported by all balance input drivers is the ability to
change the expected number of characters in the
data fi eld. The number of data characters indicated
for each of the drivers, below, are default values.
This feature virtually eliminates the need for balance
input drivers to be re-written in the event the balance manufacturer elects to alter the output string
of a balance when new models are introduced.
The format of an unknown balance can be determined by logging the balance output to display. In
order for the logging to produce meaningful results,
the cable connecting the balance to the balance
input port of the Interface must be correctly wired
or confi gured. In addition, the specifi cs of the data
frame, such as the baud rate, # of data bits, parity, #
of stop bits and handshaking (if used) must be the
same for both the balance and the Interface.
