Page 15: 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 16: 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. -
Page 17: Pickering Switch Driver Installation
Before any USB devices can be connected to the Hub and accessed, the switching part of the card must be controlled, to do this, first the Pickering standard switch driver must be installed. Select the driver required from the Pickering Switch Driver window and click “Next”: Note: Selecting the VISA Driver installs the Direct Driver at the same time. -
Page 18: Usb Driver Installation

Page 25: Programming Guide
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 26 With most drivers, before programming a Pickering card it is important to understand the basic architecture of Pickering cards. The switches on a Pickering card are organized into logical sub-units, each sub-unit containing a set of objects of similar type and use. These objects may be switches, digital outputs, digital inputs, resistors, power supplies etc, depending on the nature of the specific card.

Page 27: Card Architecture
Card Architecture The 40-738 Module contains two separate PCI devices; the USB Hub and the switching function. Both are controlled from the PXI backplane via an on-board PCI-PCI bridge. The USB Hub is controlled from the system’s PXI controller using standard Windows drivers, and the switching functions are controlled using standard Pickering switch drivers. -

Page 35: Maintenance Information
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. -
