    Unused slots in the PXI/LXI chassis are populated with blanking plates to prevent access to user I/O signals that may be present. Blanking panels are available to order from Pickering in a variety of slot widths. If the product is not used in this manner for example by using an extender card then additional care must be taken to avoid contact with exposed signals.

    SECTION 2 - TECHNICAL DESCRIPTION pickering GUIDANCE ON USING THE MODULE Sense Line Configuration The sense lines for the 41-750 ensure that the module can regulate the voltage at a remote load. The sense lines are manually configured in one of two ways using jumpers on the PCB: If one or both the sense lines are not connected to the load the battery simulator closes down the ●...
  • Page 15 SECTION 2 - TECHNICAL DESCRIPTION pickering Transient Load Response The 41-750 has been designed to provide very fast recovery from transient loads. However, if the load has an excessively large capacitive component then charging this capacitance can limit the response time. The power supply includes an internal 22µF load.

  • Page 19: Installation

    Modular products require installation in a suitable PXI/LXI chassis. The module is designed for indoor use only. PREOPERATION CHECKS (UNPACKING) 1. Check the module for transport damage and report any damage immediately to Pickering Interfaces. Do not attempt to install the product if any damage is evident.

  • Page 20: Hardware Installation

    For a system comprising more than one chassis, turn ON the last chassis in the system followed by the penultimate, etc, and finally turn ON the external controller or chassis containing the system controller. 9. For Pickering Interfaces modular LXI installation there is no requirement to use any particular power up sequence.

    2. Follow the on screen instructions, selecting a different target directory if required. It is recommended that it be installed to the default Pickering directory created during driver installation (usually C:\Pickering). 3. Once installed a new program group should be available on the Programs\Pickering Interfaces Ltd menu location.

    IVI Driver for Windows - pi40iv The pi40iv IVI (Interchangeable Virtual Instrument) driver supports all Pickering Interfaces PXI switch cards that are consistent with the Iviswtch class model - as are the great majority of cards in the System 40/45/50 ranges. It integrates well with LabWindows/CVI and LabVIEW, and is fully compatible with Switch Executive.
  • Page 24 Pickering LXI products include an SSH interface which allows remote command line access to control cards, or, using a suitable package, programmatic control. The user is advised to visit the Pickering web site for further details of all the above drivers, where documentation, example programs, and further help with driver choice are available.

  • Page 25: Programming The Module

    PROGRAMMING THE MODULE The 41-750 Battery Simulator uses the same driver software as the Pickering range of switches, pilpxi or pipx40, requiring version 2.51 or later. There is no IVI driver available for this unit at present. For full detail of the range of driver functions available the user is advised to refer to documentation for the switch drivers pilpxi and/or pipx40.
