Connecting a chromatograph analogue output to Clarity

The Clarity Station cable (INT7) connects the station to the chromatograph and it is a set of Starting, Digital output and Analog Signal cables connected to a CANNON SUB D 27-pin connector.

  1. Install your external A/D converter like Colibrick (refer to Installing Colibrick) or an A/D converter card (refer to the specific HW manual).
  2. Switch off your chromatograph.
  3. Connect the bare wires to the chromatograph depending on your equipment, configuration and the following guidelines.
    • The Signal cables "DET 1" to "DET 4" carry the main signal from the chromatograph to the computer. The connection can be asymmetrical or symmetrical.
    • The Starting cables "IN1" to "IN4" come in pairs, one part connected to the 27-pin connector and ending on a female RCA connector and the other with a male RCA connector and free leads for connection to a starting contact or a button for a manual start.
    • The Digital Output cables "OUT 1R" to "OUT 4R" end on free leads and they can be used for synchronizing autosamplers.
    Caution: The shielding must be connected. It works not only as the shielding, but also as the analogue ground against which measurement takes place. In the case of asymmetrical output of a detector (only two leads/terminals/pins/screws) the shielding must be connected to the white lead! No lead of the signal cable may remain unconnected.
  4. Connect the CANNON SUB D 27-pin connector to the A/D convertor.
  5. Switch on your computer and your chromatograph.
