6 Lower Density Versions
Custom Sizes (100s of combinations)
The 40-615A series of high density multiplexers feature a wide
range of switching configurations. It is especially useful where
a large number of small multiplexers are required. Typical
applications include signal routing in ATE and data acquisition
systems. User connections are made via a front panel 200-pin
connector.
The 40-615A can be operated as a conventional multiplexer
with break-before-make action when a new channel is selected.
Alternatively, product variants can be supplied that allow
multiple channels to be simultaneously selected.
Model 40-615A channel selection configurations have been
revised from model 40-615. The 40-615A family defaults to
single channel selection with multiple channel selection
variants defined by use of a suffix.
The 40-615A single pole high density versions include
automatic isolation switching. This connects only the currently
active multiplexer bank to the common terminal, keeping
capacitive loading and leakage current to a minimum in large
multiplexer systems. Larger multiplexers may be constructed
by daisy chaining the common signals from multiple modules.
Automatic isolation switching only applies to single channel
selection mode, for versions with multi channel selection, the
isolation relays are controlled separately from the channel
relays. To prolong contact life of the isolation relays it is
strongly advised that they are cold switched.
The 40-615A is part of a family of high density PXI multiplexer
modules all sharing similar architecture and the same 200-pin
connector, other members include the 40-610 and 40-670A
High Density Multiplexer series.
Front Panel Connector
This product is based on the obsolete Molex LFH series
connector that has been superseded by a Pickering
commissioned form, fit, function equivalent. The new
connector series is 100% compatible with the Molex
connectors allowing either gender of Pickering connector to
mate with the corresponding Molex part without issue.

SECTION 2 - TECHNICAL DESCRIPTION
FUNCTIONAL DESCRIPTION
A functional block diagram is provided in Figure 2.1. The Relay Module is powered by +5V inputs via Compact PCI
connector J1. The interface to the user test equipment is via the front panel mounted 200-pin LFH connector, J2.
The module comprises a PCB populated with relays which are two pole or single pole depending on the variant.
The relays are congured as a multiplexer with single pole isolation relays, which connect only the currently active
multiplexer bank to the analog common, thereby keeping capacitive loading and leakage currents in large multiplexer
systems to a minimum. The relays are energised via control signals from relay drivers U8 to U17. Each relay driver
is addressed by PCI bridge U1, via the control logic comprising U3 to U6, to output the required signal. Module
conguration is determined by data stored in EEPROM U7. PCI Bridge U1 is congured by EEPROM U2.

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.
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 at and solid construction to
withstand and support the combined weight of the module(s) and chassis.

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.
