Clarity - INT9 A/D converter Brief Description
1 Brief Description
This manual describes the use of the INT9
converter with Clarity software ver. 2.5 and
later.
INT9 is an internal 24-bit A/D converter card
that measures the voltages of chromatographic
and electrochemical detectors.
1.1 INT9 Acquisition card
• Up to 4 dataacquisition channels on one card
(one and two channel versions are also
available).
• The channels are completely independent
sigma delta integrating A/D converters, used
for processing positive and negative voltages.
• Four digital inputs.
• Eight digital outputs. The first four are also
designed as relay contacts.
• PCI Slot.
• Excellent reliability and temperature stability.
Fig. 1. INT9 Card
The INT9 card of integration converters is
a modernized successor of the PCI card INT7.

Clarity - INT9 A/D converter Brief Description
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.
Advantages of the INT9 A/D converter
• No loss of input signal during integration.
There are no time delays during which the
converter fails to integrate the input signal.
• No continuous servicing of the input analog
switches, which would otherwise cause errors
(offset, noise).
• Substantially smaller amounts of data entering
the computer due to individual data items
already representing partial integrals.
1.2 Hardware and software requirements
The INT9 A/D Converter for PCI slot can be
used with Clarity software on PC’s using the
following operating systems: MS Windows
2000/XP/Vista.
The PC must have one free PCI slot for your
INT9 card.
Caution! Full size PCI 2.0, 32 bit PCI slot is required. Low
profile or PCI Express slots cannot be used.
Hardware and Software Compatibility:
Software \ Windows Vista XP 2000 NT 98/Me
Clarity * Yes Yes Yes No No
Clarity Lite * Yes Yes Yes No No
CSW32 No No No No No
* From Clarity version 2.4.4.122

Clarity - INT9 A/D converter Installation
2 Installation
Ensure that you have Administrator access
rights to your Windows OS before you proceed
with the installation.
2.1 The INT9 Card
• Install Clarity software from the CDROM.
Caution! Install the Clarity software before inputting any
devices.
• Plug in the HW Key (described in the Getting
Started manual)
• Turn off the PC
• Plug the INT9 card into the PCI slot
• Start the PC
a) MS Windows 2000/XP/Vista and later
In Windows 2000/XP/Vista the drivers were
installed automatically
of the Clarity software.
b) Previous versions of MS Windows
In systems other than Windows 2000/XP/
Vista follow the procedure described in chapter
4.3 on pg. 23.
• 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
during the installation
Instruments.
2.2 Standard cable for Clarity station
The standard Clarity station package includes
a cable set composed of signal and starting
cables for connecting the CLARITY station to
the chromatograph.
• Signal cables
Labelled “DET1” to “DET4” (according to the
number of channels), the cables are supplied
as standard without connectors [bare stripped
6
Clarity - INT9 A/D converter Installation
and tinned endings – red (+), white (-) and
shielding (analogue ground)].
• Starting (marker) cables
Labelled “IN1” to “IN4” (correlating to channel
number) and tipped with CINCH connector
(female).
The following cables can be connected to this
CINCH connector:
• A cable terminated with free leads
shielding (digital ground)] for direct
connection to the chromatograph.
• A cable terminated with a button
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 labelled "OUT1R" to "OUT4R"
(according to the number of channels),
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 D-SUB 37-pin connector
(female).

for cases
2.3 Connection with Chromatograph
Connect the cables according to one of the
following diagrams in Fig. 2. Use the
symmetrical connection
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
chapter 5.1 on pg. 32.

Fig. 2. Connecting Clarity to chromatograph
2.3.1 Connecting 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) the 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 as INTEGRATOR
(signal approx. 1V). The level of the signal on
the output marked RECORDER is usually only
approx. 10mV.
For easier alterations of the wiring, we supply a
SV8 Terminal board with screw contacts for
INT7, INT9, U-PAD, U-PAD2 and Net-PAD
A/D converters.
Note: This SV8 Terminal Board is not suitable for
applications with small signals or with high
electromagnetic interference. This is because the SV8
Terminal Board uses leads and screw contacts that
are not shielded.

2.3.2 Connection of starting cables:
Starting input reacts to a change of the TTL
logical level (5V) 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
Method Setup - Measurement dialog (accessible
of the
from the
Instrument window using the - Method -
Measurement command).
Note: For schemes and hints describing the typical
autosampler wirings see the Device setup and
wiring chapter of the Getting Started Manual.

6. Enter the detector names in Name fields for
individual channels, set signal units.
Note: A detailed description of this dialog can be found in
chapter 3.1 on pg. 14.
7. Press the OK button.
The DataApex INT9 A/D Card will appear in
the Setup Control Modules list of the
System Configuration dialog.
8. Drag and drop the DataApex INT9 A/D Card
icon from the Setup Control Modules list
on the left side of the System C onfiguration dialog
to the desired Instrument tab on the right
side (or use the button to do so).
Fig. 4. System Configuration
9. Set the Start input and Ready output
numbers for your acquisition card according
to the wires being used for synchronization.
Note: The configuration dialog of the INT9 card (INT9 A/D
Card Setup) can be displayed any time by double-
clicking on its icon or using the Setup button.

2.4.1 Measuring on multiple Instruments
Rather than dragging the entire INT9 A/D
Card Driver icon from the Setup Control
Modules list (see Fig. 5), drag the
individual detector signals (TCD, FID in this
case) to separate Instruments . 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. 5. System Configuration – multiple Instruments
Note: Each independent Clarity Instrument must have
separate Start and Ready pins configured according
to the actual wiring.
