INT9 A/D converter 1 INT9 acquisition card
1 INT9 acquisition card
This manual describes the use of the INT9 A/D converter with the Clarity
software ver. 2.7 and later.
INT9 is an internal 24-bit A/D converter card that measures the voltages of
chromatographic and electrochemical detectors.
Fig 1: INT9
Brief technical overview
lUp to 4 dataacquisition channels on one card (one and two channel
versions are also available).
lThe channels are completely independent sigma delta integrating A/D
converters, used for processing positive and negative voltages.
l4 digital inputs.
l8 digital outputs. The first four are also designed as relay contacts.
lPCI Slot.
lExcellent reliability and temperature stability.
The INT9 card of integration converters is a modernized successor of the
PCI card INT7.
1.1 A/D converter types in general
Prior to collecting and processing the chromatographic signal by a
computer, the analog signal of the detector must first be converted to
digital form using an analog/digital (A/D) converter.
In principle, there are three types of A/D converters – sampling,
integrating and δΣ (Delta-Sigma) - with continuous integration). The INT9
card uses Delta-Sigma integration.

1 INT9 acquisition card Clarity Hardware
Advantages of the INT9 A/D converter
lNo loss of input signal during integration. There are no time delays during
which the converter fails to integrate the input signal.
lNo continuous servicing of the input analog switches, which would
otherwise cause errors (offset, noise).
lSubstantially smaller amounts of data entering the computer due to
individual data items already representing partial integrals.

INT9 A/D converter 3 Installation
3 Installation
Ensure that you have Administrator access rights in your Windows OS
before you proceed with the installation.
3.1 The INT9
lInstall Clarity software from the CDROM.
Caution: Install Clarity before inputting any devices.
The drivers were copied to your computer during the installation of the
Clarity software.
lPlug in the HW Key (described in the Getting Started manual).
lTurn off the PC.
lPlug the INT9 card into the PCI slot.
lStart the PC.
The drivers were installed automatically during the installation of the
Clarity software.
lThe driver is now installed, proceed to setup and wiring.
Note: When installing multiple INT9 cards, a PC restart is recommended after
the installation in order to prevent the reassignment of INT9 acquisition
channels between Clarity Instruments.
3.2 Standard cable for Clarity station
Fig 2: Cables for the Clarity station package
The standard Clarity station package with INT9 card includes a cable
composed of signal and starting cables for connecting the Clarity station
via the INT9 card to the chromatograph. The number of signal wires,
starting wires and digital output wires present corresponds to the number
of signals the INT9 card has - each signal on the card is accompanied by

a set of one signal wire, one starting wire and one digital output wire. The
2-channel INT9 card would thus have the cable with following parts:
Signal cables
Labeled DET1 and DET2, the cables are supplied as standard without
connectors [bare stripped and tinned endings – red (+), white (-) and
shielding (analogue ground)].
Starting (marker) cables
Labeled IN1 and IN2 , ended with CINCH connector (female). The
following cables can be connected to this CINCH connector:
lA cable terminated with free leads [red (+), shielding (digital ground)] for
direct connection to the chromatograph.
lA cable terminated with a button for cases where a starting contact is not
available and it is necessary to perform a manual start.
Both types of cable are supplied for each starting cable.
Digital output cables
Relay contacts labeled OUT1R and OUT2R, terminated with free leads.
These are used for synchronizing autosamplers without an AS Control
module in the ACTIVE Sequence or for controlling other devices.
At the converter end the cable is always terminated with a DB- 37F
connector (37-pin female connector).

3.3 Connection with chromatograph
Connect the cables according to one of the following diagrams in the Fig 3
on pg 6. Use the symmetrical connection only when you are sure that the
chromatograph/detector is equipped with a symmetrical output – it is
necessary to read through the instructions for the corresponding
chromatograph.
All current DataApex A/D Converters INT7,INT9,U-PAD,U-PAD2 and
Net-PAD use the same standard INT7 Connector.
Note: A description of the INT7 connector can be found in the chapter
"Tables and Specifications" on pg 40.
Fig 3: Connecting Clarity to chromatograph
3.3.1 Connection of signal cables
Signal inputs of the A/D converters are symmetrical: + (red), - (white) and
analogue ground (copper braiding).
Caution: Shielding must be connected. It serves not only as the shielding but also as
the analogue earth against which the measurement takes place. In the
case of asymmetrical output of a detector (only two connectors) shielding
must be connected to the white lead! No lead of the signal cable may
remain unconnected.
Try to connect to the detector output of the chromatograph with the largest
possible signal level, usually indicated in the chromatograph as
INTEGRATOR (signal approx. 1 V). The level of the signal on the output
marked RECORDER is usually only approx. 10 mV. For easier alterations

of the wiring, we supply a SV9 Terminal board with screw contacts for
INT7,INT9,U-PAD,U-PAD2 and Net PAD A/D converters.
Note: This SV9 Terminal Board is not suitable for applications with small
signals or with high electromagnetic interference. This is because the SV9
Terminal Board uses leads and screw contacts that are not shielded.
3.3.2 Connection of starting cables
Starting input reacts to a change of the TTL level (5 V / 0 V) or to a
connection by any contact (button, contact of relay).
The input implicitly reacts to a change from HIGH to LOW (or closing of a
contact). The input function may be altered by changing the Down option
to Up in the External Start/Stop section of the Method Setup -
Measurement dialog (accessible from the Instrument window using the
Method -Measurement command).
For schemes and hints describing the typical autosampler wiring, please
see the Connecting Autosamplers chapter of the Getting Started
Manual.

acquisition card according to the wires being used for synchronization.
Note: The configuration dialog of the INT9 card (DataApex INT9 Setup) can be
displayed any time by double-clicking on its icon or using the Setup button.
3.4.1 Measuring on multiple Instruments
When measuring on multiple instruments using only a single INT9 to
gather data, rather than dragging the entire INT9 icon from the Setup
Control Modules list , drag the individual detector signals (FID,UV-VIS in
this case) to separate Instruments . See Fig 6 on pg 10. The Instrument
to which the particular signal is connected is listed to the right of the
detector name in the Setup Control Modules section.
Fig 6: System Configuration – multiple instruments
Note: Each independent Clarity Instrument must have separate Ext. Start
Dig. Input and Ready Dig. Output pins configured according to the actual
wiring.
Note: A larger number of Instruments can be set than the amount you have
purchased. You will not be able to measure on the surplus Instruments
(indicated by a blue symbol of the curve on the tab), but you may use them
e.g. for “offline” preparation of methods.

3.4.2 Using multiple INT9 converters
When using multiple A/D cards, it will be necessary to add the INT9 card
again, repeating the entire procedure described in the chapter
"ClarityConfiguration" on pg 8. from Step 3.
Fig 7: System Configuration – multiple INT9s
Individual detectors from all cards can be assigned to multiple instruments
and combined together arbitrarily. In this example, all signals from INT9
A/D Card 1, as well as all signals from INT9 A/D Card 2 and one signal
(Pressure) from U- PAD2 are assigned to the Instrument 1 , while the
second signal (UV) from U-PAD2 is assigned to the Instrument 2 .
While there are several cards assigned to the same instrument, it is
necessary to select which card will be used for Ext. Start Dig. Input and
Ready Dig. Output signals .
All added A/D converters (e.g. INT9 ) must have their drivers properly
installed. There must be correct number of items in the Windows OS
Device Manager, otherwise you will not be able to add it in the System
Configuration dialog and configure its detectors to Instruments.

There are generally two places for setting the parameters of the INT9 A/D
converter in Clarity:
lThe DataApex INT9 Setup dialog for setting the parameters that are set
with respect to the type of connected signal.
lThe Method Setup - Acquisition tab for setting the parameters related to
the type of analysis.
4.1 DataApex INT9 Setup
The DataApex INT9 Setup dialog sets the parameters of the INT9
converter and since it depends on the type of connected detector, it is not
going to be changed often.

4 Using the INT9 card Clarity Hardware
Channel 1 (to 4)
For each channel of the INT9 A/D Card the name of the signal can be
edited in the Name field and the Set Units... button can be used to change
other signal parameters. Effects of these changes can be seen in other
fields of the respective Channel 1 (to 4) section.
Name
This field will be used to describe the signal in the Chromatogram
window.
Inversion of Signal
Inverts the polarity of the signal from the detector. This function can
also be used for easy correction of inversely connected wires.
Bipolar
Both positive and negative voltages will be measured. Unchecking the
Bipolar option will improve the resolution of the signal by 1 bit. On the
other hand, it will also restrict the measuring of negative signals (i.e.
below zero).
Set Units...
Invokes the Detector Units dialog.
Fig 10: Detector Units
lQuantity – Field for entering a name of the y-axis in the graph of the
measured signal.
lUnits – Field for entering the unit symbol, along with the prefix.
lCoefficient – Allows to enter the coefficient between the selected units
and mV (default).
lAutoprefix – Allows to enter the unit prefix. In graphs, units will be
scaled automatically, while in the tables, units with the prefix entered
will be used.
Synchronize Start with Digital Input
Maps the INT9 A/D converter channel to selected External Start
Digital Input. It enables faster and more accurate synchronization of
channels with the start signal. Especially for short analyses the
necessary time lags at the start of the acquisition are significant. When
measuring multi-detector chromatograms it will minimize the time shift
between detector signals and thus improve the detection of peaks.

Note: In most parts of Americas, the 60 Hz mains frequency is usual, while the
rest of the world tends to use 50 Hz mains frequency (pre- set as default).
The 50 Hz frequency is common in countries using 230V power supply,
while the 60 Hz is connected to the 117V power supply.
