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).
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.
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.

The following cables can be connected to this CINCH connector: • A cable terminated with free leads [red (+), shielding (digital ground)] for direct connection to the chromatograph.

Clarity - INT9 A/D converter 2.3.2 Installation 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).
Clarity - INT9 A/D converter Installation 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.
Clarity - INT9 A/D converter 2.4.1 Installation 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.
Clarity - INT9 A/D converter 2.4.2 Installation 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.
Clarity - INT9 A/D converter Installation Device Manager, otherwise you will not be able to add it in the System Configuration dialog and configure its detectors to Clarity Instruments. Fig. 7. Note: Device Manager – two INT9 cards A maximum of four INT9 cards can be configured and used in Clarity simultaneously.
Clarity - INT9 A/D converter Using the INT9 card 3 Using the INT9 card There are generally two places for setting the parameters of INT9 A/D Converter in Clarity. • The INT9 A/D Card Setup dialog for setting the parameters that are set with respect to the type of connected signal. • The Method Setup – Acquisition tab for setting the parameters related to the type of analysis. 3.
Clarity - INT9 A/D converter Using the INT9 card Channel 1 (to 4) For each channel of the INT9 A/D Converter the name of the signal can be edited in the Name field and the Set Units... button can be used to change other signal parametres. 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.
Clarity - INT9 A/D converter Using the INT9 card 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: 3.2 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).
Clarity - INT9 A/D converter Using the INT9 card 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.
Clarity - INT9 A/D converter 3.2.2 Using the INT9 card Method Setup - Measurement Fig. 11. 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. 10). Start Only The external signal only starts an analysis. Triggering the input will not influence the acquisition in progress.
Clarity - INT9 A/D converter Using the INT9 card Down 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.

Clarity - INT9 A/D converter 4.2 Troubleshooting Problems with INT9 driver • “Board malfunction” If the error message "Board malfunction" appears, the card is probably incorrectly inserted or damaged. Solution: Check whether the INT9 A/D card is correctly set in the ISA slot. The card should be tucked fully and should not move in the slot. If this does not help, contact technical support to replace the damaged card.
