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
l Up to 4 dataacquisition channels on one card (one and two channel
versions are also available).
l The channels are completely independent sigma delta integrating A/D
converters, used for processing positive and negative voltages.
l 4 digital inputs.
l 8 digital outputs. The first four are also designed as relay contacts.
l PCI Slot.
l Excellent 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 -
1 INT9 acquisition card Clarity Hardware
Advantages of the INT9 A/D converter
l No loss of input signal during integration. There are no time delays during
which the converter fails to integrate the input signal.
l No continuous servicing of the input analog switches, which would
otherwise cause errors (offset, noise).
l Substantially 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
l Install Clarity software from the CDROM.
Caution: InstallClarity before inputting any devices.
The drivers were copied to your computer during the installation of the
Clarity software.
l Plug in the HW Key (described in the Getting Started manual).
l Turn off the PC.
l Plug the INT9 card into the PCI slot.
l Start the PC.
The drivers were installed automatically during the installation of the
Clarity software.
l The 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
- 4 -
3 Installation Clarity Hardware
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:
l A cable terminated with free leads [red (+), shielding (digital ground)] for
direct connection to the chromatograph.
l A 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).

INT9 A/D converter 3 Installation
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 chromatogr aph
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
signalsor with high electromagnetic interference. Thisisbecause 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 – multipleinstruments
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 symbolof the curve on the tab), but you may use them
e.g. for “offline” preparation of methods.

3 Installation Clarity Hardware
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 – multipleINT9s
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:
l The DataApex INT9 Setup dialog for setting the parameters that are set
with respect to the type of connected signal.
l The 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.
Fig 9: DataApex INT9 Setup
Number of Channels
Indicates the number of data acquisition channels.
- 13 -
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
l Quantity – Field for entering a name of the y-axis in the graph of the
measured signal.
l Units – Field for entering the unit symbol, along with the prefix.
l Coefficient – Allows to enter the coefficient between the selected units
and mV (default).
l Autoprefix – 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.

Digital Output Names
Allows to change the names of digital outputs. These names will be
used in the Digital Output Control dialog in the chapter "Digital Inputs
and Outputs" on pg 20.
Fig 12: Digital Output Names
Supply Frequency
Allows to change the mains Supply Frequency Suppression. It is used
for suppressing the interference on the specified frequency level. This
setting influences the sampling frequency as well.
- 15 -
4 Using the INT9 card Clarity Hardware
Note: In most parts of Amer icas, 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.
- 16 -
INT9 A/D converter 4 Using the INT9 card
4.2 Method Setup
Parameters of the Method Setup - Acquisition and Method Setup -
Measurement dialogs depend on the type of analysis (measurement
conditions), so they can be specific for various types of analysis. This is
the reason for them to be a part of the method.
Caution: The parameters can't be changed during analysis.
4.2.1 Method Setup - Acquisition
Fig 13: Method Setup - Acquisition (INT9)
Select Detector
Selects the detector whose parameters will be set. If there is only one
detector (channel) configured on the Clarity Instrument, this control will
not be accessible.
Range
Selects the input voltage range (in mV). The selected range corresponds
to the maximum output voltage of the detector that the A/D converter can
still process.
Available ranges for INT9 card are 156, 1 250 and 12 123 mV.
Sample Rate
Depending on Supply Frequency filter selected in the System
Configuration – DataApex INT9 Setup dialog, see the chapter "DataApex
INT9 Setup" on pg 13. The available sampling rates are 6.25, 12.5 , 25,
50, 100 , 200 and 400 samples per second (for 50Hz supply frequency
- 17 -
4 Using the INT9 card Clarity Hardware
filter) or 7.5, 15, 30, 60, 120 , 240 and 480 samples per second (for 60Hz
supply frequency filter).
Higher sampling rate allows for the measurement of narrower peaks, but it
also means a larger amount of data which will affect the size of the
resulting chromatogram and the speed of its processing.
Sample rate sufficient for successful peak detection is about 20 samples
per narrowest peak.
A higher sampling rate also increases the amount of noise and will need
setting the Peak Width parameter accordingly in the Integration Table on
the Method Setup - Integration tab.
Note: Range and Sampling Rate are set individually for each detector.
- 18 -

4.2.2 Method Setup - Measurement
Fig 14: Method Setup - Measurement
External Start/Stop
Enables control from an external signal.
Note: The input used for an external start from a chromatograph can be set in
the System Configuration dialog, see Fig 4 on pg 8.
Start Only
The external signal only starts an analysis. Triggering the input will not
influence the acquisition in progress.
Start - Restart
The external signal terminates the analysis in progress and at the
same time starts a new one. The first signal starts the analysis; the
second signal terminates it and at the same time starts a new one - the
so-called continuous measurement.
Start - Stop
The external signal starts and stops an analysis. The first signal starts
the analysis; the second signal stops it, etc.
Down
The station reacts to changes in voltage in relevant controlling input
from high (> 3 V) to low (< 0.7 V), or to contacts closed in the relay.
Up
The station reacts to changes in voltage in relevant controlling input
from low (< 0.7 V) to high (> 3 V), or to contacts opened in the relay.

5 Troubleshooting Clarity Hardware
5.3.4 Reinstallation of drivers in Windows 2000
Note: Windows 2000 is supported until Clarity version 3.0 only.
After installing Clarity and the INT9 device, the Device Manager either
does not display the Chromatography Devices – DataApex Acquisition
device, Model 9.XX item at all or it displays a yellow exclamation mark
next to the item that indicates that the device is not working properly.
Fig 30: Device Manager in Windows 2000
If the " DataApex Acquisition device, model 9.XX" item is missing,
Windows has automatically installed incorrect driver.
If you are able to locate which device was mistakenly installed instead of
the INT9 driver, you can open its Properties and Update this driver. In the
manual installation process, select the correct drivers analogically to the
description in the chapter "Installing the correct driver manually" on pg
34.
If the correct driver cannot be determined, the last installed driver will have
to be removed.
Caution: This procedure can be used safely only if you did not install any other
hardware since the installation of the converter.
5.3.4.1 Deleting incorrect *.INF files in the system
Note: Be sure to have the Clarity software installed already.
l Open the C:\WINNT\INF (C:\WINDOWS\INF) folder in Windows Explorer.
Note: You may have to allow for the hidden system filesto be displayed. In menu
select Tools - Folder Options - View tab then set the Hidden Files and
Folders option to Show Hidden Files and Folders.

Fig 38: Data Acquisition disabled
Other manifestationsof this er ror are also: Method Setup - Acquisition tab missing,
Method - Acquisition command non-functional, Run, Stop, Abort and other similar
commands non- functional in the Single Analysis, Sequence or Device Monitor
windows. Possible causes are:
Description: a) You are using Clarity Offline or a Clarity DEMO version, which does not
enable the measurement of chromatograms.
Fig 39: Clarity Offline and ClarityDEMO
Solution:
Description: b) Detector is not allocated to the Clarity Instrument:
Check whether there is a blue line with the title OFFLINE displayed in the main
Clarity window under the symbols of the Instruments, or the title DEMO in
theClarity window header.
In case of Clarity DEMO, use the Windows Start menu to locate the Clarity
DEMO group in the AllPrograms section and select the Remove Clarity item there.
Then, use the correct Clarity installation CD to install the full version.
In case of the Clarity Offline station, remove the hardware key with the Offline
license and insert the hardware key with the Clarity full licence.
Solution:
Fig 40: Detector not allocated to the Instrument
Open the System Configuration dialog from the Clarity window using the System Configuration... command and check the tab of the corresponding Instrument -
Instrument X. If it has no allocated detectors, add them.
In the left-hand list Setup Control Modulesselect the correct detector connected to
the A/D card you are using and drag it to the corresponding instrument on the
right.

6.2 Parameters of digital Inputs and Outputs
Digital Outputs
The card contains eight digital TTL outputs (OUT1-OUT8) with maximum
permissible current of 20 mA at both levels. The first four outputs are also
designed as relay contacts (OUT1S1/OUT1S2- OUT4S1/OUT4S2).
The maximum permissible current is 100 mA , the maximum- switched
voltage is 100 V and the contact resistance is 150 mΩ . The relay is
onstate (closed) at level LOW of a relevant digital output.
Digital Inputs
The board contains four digital TTL inputs IN1 to IN4.
To suppress the contact bouncing the digital inputs are equipped with
monostable toggles that prolong any change affecting the input to at least
200 ms (to ensure that the station is able to detect it).
A pulse with duration of at least 1 ms is necessary to excite the toggles.
