The 40-575A/576/577/578/579 are a range of high density
matrix modules able to switch up to 2 A or 300 VDC/250 VAC.
They are constructed using high quality electro-mechanical
relays for high switching confidence.
The range is as follows:
• 40-575A-001 84x4, 1-Pole Matrix
• 40-576-001 64x6, 1-Pole Matrix
• 40-577-001 50x8, 1-Pole Matrix
• 40-578-001 36x12, 1-Pole Matrix
• 40-579-001 28x16, 1-Pole Matrix
The modules are designed for switching medium voltage
and power signals. The user signal connection is via a
robust 160-pin DIN 41612, 78-pin D-type or 50-pin D-Type
connector that is fully supported by the wide range of
Pickering Interfaces cable and connector accessories.
Relay Cycle Counting
To aid with module “health” monitoring, the 40-575A is provided
with a relay cycle counting cycle feature. The number of
operations per contact are stored on the module and can be used
to determine if a relay is approaching EOL. This information could
allow system connections to be revised so that signals applied to
heavily used contacts are swapped with lightly used contacts to
prolong the working life of the relay(s).

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 (40-576), 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.

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.

Matrix Architecture
The 40-575A is a single pole switching matrix with 84 connections on the X-axis and 4 connections on the Y-axis.
Connections are made by operating the relays at the crosspoints between X and Y lines allowing single X-Y connections,
or X-X connections using a Y line as a path. The 40-576, 40-577, 40-578 and 40-579 are controlled in the same way but have
matrix sizes of 64x6, 50x8, 36x12 and 28x16 respectively. The matrix architectures are shown in the diagrams below:

NOTE: The matrix supports concurrent switch paths for X to X and Y to X connections, however connections between
different Y axis lines (e.g. Y1 to Y2) are not permitted.
The entire matrix is treated as a single programming sub-unit designated as Sub-Unit 1. Some simple examples are show
on the next page using the provided drivers: the IVI driver, the Direct IO driver, and the IVI compliant driver.

Section 4 - Programming
Programming the Matrix Using The IVI Driver, Direct I/O Driver or VISA Driver
This section provides some code fragments which show how to control the High Density Matrix using the IVI Driver, Direct
I/O Driver or the VISA Driver.
Once the drivers are installed the manual “Sys40Prg.pdf” and driver help files which fully describes these functions can
be found in the Pickering folder(s) or the Pickering entries on your Start Menu.
The card must be opened before use and closed after using the following function calls:
Direct Driver - Open with PIL_OpenCards or PIL_OpenSpeciedCard and close with PIL_CloseCards or
PIL_CloseSpeciedCards respectively.
VISA Driver - Open with pipx40_init, and close with, pipx40_close.
Setting a Matrix Crosspoint:
Using the IVI driver:
pi40iv_Connect(vi, “x1”, “y2”); //set crosspoint x1, y2 to on
pi40iv_Disconnect(vi, “x1”, “y2”); //set crosspoint x1, y2 to o
Using the Pickering Direct I/O driver:
DWORD SubUnit = 1;
PIL_ClearSub(CardNo, SubUnit); //clear all crosspoints to o state
PIL_OpCrosspoint(CardNo, SubUnit, 2, 1, 1); //set crosspoint x1, y2 to on
PIL_OpCrosspoint(CardNo, SubUnit, 2, 1, 0); //set crosspoint x1, y2 to o
Using the VISA driver:
ViUInt32 SubUnit = 1;
pipx40_clearSub(vi, SubUnit); //clear all crosspoints o state
pipx40_setCrosspointState (vi, SubUnit, 2, 1, VI_ON); //set crosspoint x1, y2 on
pipx40_setCrosspointState (vi, SubUnit, 2, 1, VI_OFF); //set crosspoint x1, y2 o
