    Do not attempt to record from both the BNC and DIN pod connectors for any one input at the same time, or the signals will compete. Pod connectors allow the connection of ADInstruments pods – small, low- cost units for specific tasks, for use with precalibrated transducers.

  • Page 25: A Technical Aspects

    A P P E N D I X Technical Aspects This appendix describes some of the important technical aspects of the PowerLabs of the /30 series, to give some insight into how they work. You do not need to know the material here to use your PowerLab. It is likely to be of interest to the technically minded, indicating what the PowerLab can and cannot do, and its suitability for particular purposes.

  • Page 26: How It Works

    PowerLabs are also fitted with an I C expansion port. This 9-pin port allows ADInstruments front-ends to be added to the system. It provides both power and communications to allow software control of the attached hardware. The digital input and output connectors allow the PowerLab to monitor and control external devices, respectively.

  • Page 27: The Analog Inputs

    Because of these power limitations, you should not use the PowerLab as a power source for external devices other than those produced by ADInstruments. The Analog Inputs PowerLab input amplifiers have been designed with a considerable amount of computer-controlled gain (up to ×...

    Calibration facilities. It is good practice to calibrate a measuring system from transducer to output. After applying two known values to the transducer and recording both signals, use the units conversion feature of ADInstruments software to calibrate the transducer and display readings in the appropriate units.

  • Page 29: The External Trigger

    The External Trigger The external trigger provides an input for synchronizing sampling to external devices. It allows either a voltage level or a contact closure to trigger recording. Note: the trigger signal length must be at least 5 μs. When a trigger event occurs, the trigger indicator light glows yellow.

  • Page 30: Connections

    Pod Connectors The (8-pin DIN) pod connectors on Inputs 1 – 4 of the /30 series PowerLabs allow the connection of ADInstruments pods — small, low-cost units that provide alternatives to front-ends for specific tasks, for use with precalibrated transducers and so on. Transducers should not be connected directly to pod connectors, unless labeled to do so (unsuitable transducers will give a very weak signal).

  • Page 31: I 2 C Expansion Socket

    You should not attempt to run other external devices from the I C socket as it is designed for use only with ADInstruments front-ends. Only 50 mA maximum current can be provided through this bus, so it should not be used for third-party devices that draw more current.

    USB Connections Figure A–7 PowerLabs have a USB 2.0 port, and connect to a computer with USB ports or The USB icon and port a PCI USB card installed, allowing high data transfer rates to USB 2.0- compliant computers (slower transfer to USB 1.1-compliant computers). On a PC, USB 1.1 requires Windows 98 or later.
