2 Installation Clarity
2.4.2 Chromatograph
Connect cables according to one of the diagrams in Fig 4 on pg 7. Use a
symmetrical connection only if 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,
Colibrick, and Net PAD use the same standard INT7 Connector.
Note: The INT5 cable (obsolete type) requires a reduction to the INT7 card,
which can be ordered separately (p/n A57).
Detailed description of individual connectors wiring is provided in the
Reference Guide in the chapter Technical Specification.
Principles of connection of signal cables:
Signal inputs of the A/D converters are symmetrical: + (red), - (white),
analogue earth (copper braiding).
Caution: The shielding must be connected. It works not only as the shielding, but
also as the analogue earth against which 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 output of the chromatograph detector with the largest
possible level of signal, usually indicated as INTEGRATOR (signal
approx. 1V). The level of the signal on the output marked RECORDER is
only about 10mV.
