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

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

Page 7
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).
[red (+),
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.

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.

Clarity - INT9 A/D converter Installation
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.

Clarity - INT9 A/D converter Installation
2.4.2 Using multiple INT9 cards
When using multiple A/D cards, it will be necessary to add the INT9 card again, repeating the entire procedure described in chapter 2.4 from Step 3.
Fig. 6. System Configuration – two INT9 cards
Individual detectors from all cards can be assigned to multiple instruments and combined together arbitrarily. In this example, all signals from INT7 A/D Card, as well as all signals from INT9 A/D Card 2 and one signal (Pressure) from INT9 A/D Card 1 are assigned to the instrument 1, while the rest of the signals from INT9 A/D Card 1 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 Start and Ready
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

Supply Frequency
Allows to change the Mains Supply Frequency Suppression. It is used for suppresing the interference on the specified frequency level. This setting influences the sampling frequency as well.
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.
3.2 Method Setup
The Method Setup – Acquisition and Method Setup –
Measurement
that depend on the type of analysis (measuring conditions) are set and so it is expected that they will be specific for various types of analysis. This is the reason for them to be a part of the method.
Caution! Parameters cannot be changed during analysis.

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 displayed.
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, 1250 and 12 123 mV.
Sample Rate
Depending on Supply Frequency filter selected in the
System Configuration - INT9 A/D Card Setup
dialog, the available sampling rates are 6.3,
12.5, 25, 50, 100, 200 and 400 samples per
second (for 50Hz mains frequency filter) or 7.5,
15, 30, 60, 120, 240 and 480 samples per
second (for 60Hz mains 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.
Note: Range and Sample Rate are set individually for
each detector, as opposed to Mains Frequency set for the INT9 A/D card as a whole.

System Configuration
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.

The station reacts to changes in voltage in the relevant controlling input from high (> 3V) to low (< 0.7 V), or to contacts closed in the relay.
Up
The station reacts to changes in voltage in the relevant controlling input from low (< 0.7 V) to high (> 3V), or to contacts opened in the relay.
3.3 Digital Inputs and Outputs
The INT9 converter contains eight digital TTL outputs, where the first four are also designed as relay contacts. The converter contains four digital inputs IN1 - IN4. The first two inputs are also equipped with optocouplers.

5.2 Parameters of digital Inputs and Outputs
The card contains eight digital TTL outputs (OUT1-OUT8) with a 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
Ω
the contact resistance is 150 m onstate (closed) when there is a LOW level of a relevant digital output.
The card contains 4 digital inputs IN1 to IN4. To suppress 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 in order to excite the toggles.
