Pickering PXI Fiber Optic MEMS Switching modules are
available in many high density formats with a choice of
5 different connector styles to suit most applications:
FC/APC (for optimal performance), FC/PC and SC/PC
for general applications and LC and MU for high density
applications.
The fiber optic multiplexers connect the optical channel
by redirecting the optical signal into a selected output
fiber. This is achieved using Micro-Mechanical Mirrors
driven by a highly precise mechanism and activated via
an electrical control signal.
The range of MEMS (Micro-Electro-Mechanical-Systems)
based optical switches is:
40-850 – Single or Dual 4 Channel Multiplexer
40-852 – Single 8 Channel Multiplexer
40-855 – Single, Dual, Triple or Quad 2 Channel
Multiplexer
Pickering will construct custom optical systems to
customers precise requirements. We have a large
range of electrical switching modules which can form a
complete PXI based telecom switching solution.
MEMS technology offers many advantages over
traditional Optical Prism Technology as used in module
types 40-810/815/820. MEMS offer similar optical
performance but with lower price, higher packing density,
faster operate time and much longer operating life.

FUNCTIONAL DESCRIPTION
Functional block diagrams for the 40-855 are provided in Figures 2.1 and 2.2. The Fiber Optic Switch Module is
powered by a +5V input via Compact PCI connector J1. The module comprises Fiber Optic switches which connect
an optical channel by redirecting the optical signal received at the common input into a selected output bre. This is
achieved using Micro-Mechanical Mirrors driven by a highly precise mechanism. These are activated by electrical
control signals via buffers from driver devices. The registers of the drivers are addressed by PCI bridge U1 to output
the required signal. PCI Bridge U1 is congured by EEPROM U2.

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 le), 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 le containing
additional installation information. A single installation covers all cards in the System 40, System 45 and System
50 ranges.
When installation completes, the installed drivers’ ReadMe le 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)
1. The chassis must be electrically installed in accordance with local regional electrical codes by a qualied
engineer.
2. 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 VII.
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 rmly seats into the backplane. The front panel of the
module should be ush 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 nally 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.

Software drivers are supplied for Microsoft Windows operating systems, with specic support for the following
development environments:
●Microsoft Visual Studio (VB, C++, C#)
●Borland C++
●National Instruments LabWindows/CVI
●National Instruments LabVIEW and LabVIEW RT
Windows drivers are supplied in the form of Dynamic Link Libraries, which should also be usable in any other
development environment that supports them.
Some recent drivers developed for the LXI platform are capable of addressing both PXI and LXI domains. Such
duality may be of help to users considering future migration from PXI based systems to LXI based systems, or
indeed systems containing both PXI and LXI components.
Programming for PXI
A number of different Windows drivers are available to meet particular system requirements, and should none of
these be suitable there is also the option of register-level programming. Drivers are generally ‘universal’, handling all
models in the System 40, 45 and 50 ranges; however some models that are not compliant with the Ivi Swtch class
cannot be used with the pi40iv IVI driver. The pipx40 and Pilpxi drivers are also applicable to certain models in the
System 41 (PXI Instruments) range - see these drivers’ System 41 support list.
Please note that this documentation is available in its most up-to-date form as HTML help les, fully hyperlinked for
easy access - both pipx40 and Pilpxi documents are included in the Pipx40vpp software installation.
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. It is also usable
in general-purpose programming environments such as Visual C++ and Visual Basic.
Prior installation of the VISA and IviEngine from National Instruments are required for the correct installation and
operation of this driver.
VISA Driver for Windows - pipx40
The pipx40 driver conforms to the VISA (Virtual Instrument Software Architecture) standard for programmable
instrumentation. Instrument control environments such as LabVIEW and LabWindows/CVI are based on VISA, and
pipx40 support libraries are provided for them.
Prior installation of VISA from National Instruments is required for the operation of this driver.
Where VISA is available, pipx40 can also be used in general-purpose programming environments such as Visual
C++ and Visual Basic. When IVI is not a system requirement this driver will often yield faster operation than the
pi40iv driver.
Direct I/O Driver for Windows - Pilpxi
The Pilpxi driver accesses cards directly, without using the VISA software layer, while offering similar overall
functionality to pipx40. It is most commonly used in general-purpose programming environments such as Visual
C++ and Visual Basic. Operating speed of the VISA and Direct I/O drivers is generally comparable.
