  • 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.

    MODULE ARCHITECTURE The 8-bit version of the 40-296 Potentiometer Module is available with 5 or 9 separate channels which can be programmed with values between 0Ω and 255Ω. 12-bit, 16-bit and 24-bit versions are also available which have fewer channels and a greater resistance range - see the Specifications section for details.
  • Page 25 SECTION 4 - PROGRAMMING GUIDE pickering Here are examples of using the drivers with the 8-bit versions of the 40-296.

    For PXI modules which are supported in one of Pickering Interfaces’ Modular LXI Chassis (such as the 60-102B and 60-103B) no module software update is required. If the module was introduced after the LXI chassis was manufactured the module may not be recognized, in this case the chassis firmware may need upgrading.

  • Page 43: Calibration

    The 40-296 should be tested with a 6.5 digit DMM or better. The user must use a 4 terminal resistance measurement to avoid the introduction of errors due to leads.
  • Page 44 To aid users to establish test limits the following generic tables should be used for the standard modules. The tables can be copied to record the results for each channel. Similar principles can be applied to custom modules, if guidance is needed please consult your Pickering Interfaces representative.
