Section 2 - Technical Description
Functional Description
A functional block diagram is provided in Figure 2.1. The Module is powered by the +5V and +3.3V supplies from the PXI
backplane via Compact PCI connector J1. The interface to the user’s equipment is via the front panel mounted 160-pin
DIN41612, 78-pin D-type or 50-pin D-type male connector (dependent upon the module vari.
The module comprises a mother board and a daughter board populated with 1-pole electro-mechanical relays configured as
an 84x4 (40-575A), a 64x6 (40-576A), a 50x8 (40-577), a 36x12 (40-578) or a 28x16 (40-579) matrix. The relays are energised
via control signals from relay drivers U15-22 & U26-33. Each relay driver is loaded with serial data from PCI bridge U1 to
operate the required matrix crosspoint.The main PCI interface circuitry and the drivers and relays that make up one half of
the matrix are built onto the mother board. The daughter board is fitted on top of the mother board and is populated with
the drivers and relays that make up the other half of the matrix. Signals are sent between the two halves of the matrix via
an inter-PCB connector. Module configuration is determined by data stored in EPROM U8. PCI Bridge U1 is configured by
EPROM U7.

Pre-operation 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.
2. Position the chassis relative to any other equipment the module(s) will connect with. Ensure the chassis is not
connected to the electrical supply.
3. Ensure that the designated area for the chassis containing the module is of flat and solid construction to withstand
and support the combined weight of the module(s) and chassis.
!
Refer to the Warnings and Cautions at the front of this manual
Modular products require installation in a suitable PXI/LXI chassis. The module is designed for indoor use only.

Section 3 - Installation
Software Installation
First install the appropriate Pickering PXI switch card drivers by running the installer program Setup.exe (provided in a compressed zip
file), either from the CD-ROM supplied, or by downloading the latest version from our website: pickeringtest.com - the recommended
method. Setup is accompanied by a ReadMe file containing additional installation information. A single installation covers all Pickering
switching and simulation PCI, PXI and PXIe products.
When installation completes, the installed drivers’ ReadMe file is offered for display. It can also be displayed later using a shortcut on
the Programs>>Pickering menu.
If you are not a LabVIEW user you should choose the “full” version, and once that has been installed run the LabVIEW Runtime Engine
installer via the shortcut on the Programs>>Pickering menu. In the absence of LabVIEW the Runtime Engine is required to support the
Pickering Test Panels application.

Hardware Installation Electrical Connection (Chassis)
The chassis must be electrically installed in accordance with local regional electrical codes by a qualified engineer.
The chassis must be grounded.
Electrostatic discharge can damage the components on the module. To avoid such damage in handling the board refer to page vi.
Ensure that there is adequate ventilation.
The module should be installed in accordance with the following procedure:
1. Ensure that the system is turned OFF but still connected to mains so that it remains grounded.
2. Choose an appropriate slot in the rack.
3. Remove the blanking plate for the chosen slot.
4. Ensure that the injector/ejector handle is in its downward position. Align the module with the card guides on the top and bottom of
the slot.
Do not raise the injector/ejector handle whilst inserting the module as the module will not insert properly.
5. Hold the handle whilst slowly sliding the module into the card guides until the handle catches on the injector/ejector rail (refer to
Figure 3.1).
6. Raise the injector/ejector handle until the module firmly seats into the backplane. The front panel of the module should be flush with
the front panel of the chassis.
7. Secure the front panel of the module using both screws to the chassis front panel mounting rails.
8. In a system employing a remote control interface to connect an external controller to a PXI chassis or to link multiple chassis,
power-up the system as follows:
a. For a system comprising an external controller and one chassis, power up the chassis before powering up the external controller.
b. 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.
