WARNINGS AND CAUTIONS
WARNING - HAZARDOUS ENVIRONMENTS SYMBOL
This product is not specically designed for use in hazardous environments, for example in explosive
atmospheres. If the product is to be used in hazardous environments we recommend that the user
ensures suitable protective measures are taken.
!
WARNING - DANGER OF ELECTRIC SHOCK SYMBOL
This module may contain hazardous voltages. Before removing the module from the rack remove all
supplies and disconnect user I/O signals.
Unused slots in the host chassis are populated with blanking plates to prevent access to user I/O
signals that may be present. Blanking panels are available to order from Pickering in a variety of
slot widths. If the product is not used in this manner for example by using an extender card then
additional care must be taken to avoid contact with exposed signals.
Not to be used in safety critical circuits, refer to the Pickering Interfaces’ terms & conditions of sale.
This module must not be used for the switching of Mains Circuits. For the switching of voltages up
to the module’s full specication, Secondary Circuit power supplies and the Device Under Test must
be fully isolated from the Mains Circuit and the safety earth.
The host chassis must be correctly installed and be connected to mains or factory safety ground,
please refer to your chassis installation manual.
Diagram Showing Separation Between The Mains Circuit and Secondary Circuit / DUT
For the purposes of this document, a Mains Circuit is an installation classied as Overvoltage
Category II up to 300V. Separation between the Secondary Circuit and Mains Circuit is achieved
by a transformer in which the primary windings are separated from the secondary windings by
reinforced insulation, double insulation, or a screen connected to the protective conductor terminal.
CAUTION - HANDLING OF ELECTROSTATIC-SENSITIVE DEVICES SYMBOL
Certain semiconductor devices used in this equipment are liable to damage due to static voltage.
Observe the following precautions when handling these devices in their unterminated state, or
sub-assemblies containing these devices:
1. Persons removing sub-assemblies from equipment using these devices must be earthed by a
wrist strap and a resistor at the point provided on the equipment.
2. Soldering irons used during the repair operations must be low voltage types with earthed tips and
isolated from the mains voltage by a double insulated transformer.
3. Outer clothing worn must be unable to generate static charges.
4. Printed Circuit Boards (PCBs) tted with these devices must be stored and transported in
anti-static bags.

The 40-635A 2 Amp Multiplexer module is available in 9 standard
and 9 half density congurations. All congurations use high quality
electro-mechanical signal relays allowing each channel to switch
current up to 2A and voltage up to 300VDC/250VAC.
The module is suitable for signal routing in ATE and data acquisition
systems. Larger multiplexers may be constructed by daisy chaining
the common signals from multiple modules. Connections are made
via a front panel 78-pin D-type connector.
The 40-635A can be operated as a conventional multiplexer
with break-before-make action when a new channel is selected.
Alternatively, 2-pole, 4-pole and 8-pole variants of the multiplexer
can be supplied that allow multiple channels to be simultaneously
selected.
Note: The multiple channel selection option is not available for
1-pole versions of the 40-635A multiplexer.
The 40-635A channel selection congurations have been revised
from the 40-635. The 40-635A module defaults to single channel
selection with multiple channel selection variants dened by use of
a sufx.

FUNCTIONAL DESCRIPTION
A functional block diagram is provided in Figure 2.1. The Multiplexer Module 40-635A is powered by a +5V input via
Compact PCI connector J1. The interface to the user test equipment is via the front panel mounted 78-pin D-type
connector, J2. The module comprises a PCB populated with up to 36 electro-mechanical relays depending on the
version of the module. Wire links are used to factory congure the module into one of nine different multiplexer
congurations. The relays are energised via control signals from relay drivers U8 to U10. The relay drivers are
addressed by PCI bridge U1 to output the required signal. Module conguration is determined by hardwired links
and data stored in EEPROM U7. PCI Bridge U1 is congured by EEPROM U2.

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.
