WARNING - Hazardous Environments Symbol
This product is not specifically 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.
!
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:
• 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.
• 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.
• Outer clothing worn must be unable to generate static charges.
• Printed Circuit Boards (PCBs) fitted with these devices must be stored and transported in anti-static bags.
Warnings & Cautions
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 PXI/PXIe/LXI 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.
CAUTION - Product Documentation Symbol
Suitably qualified & trained users should ensure that the accompanying documentation is fully read and
understood before attempting to install or operate the product.
!
Safety Instructions
Safety Instructions
All cleaning and servicing requires the equipment to be isolated and disconnected from the power source and user I/O signals
(refer to the Maintenance Section).
• Appropriate manual handling procedures should be followed as dictated by the weight of the individual module or the
combined weight of the modules & chassis.
• Should a fault occur with the module or chassis, immediately isolate and disconnect the incoming power to the chassis and
the user I/O signals.
• Ensure the equipment is installed, operated and maintained by trained and authorised personnel.
• For suitably equipped products in the event of an emergency press the red “emergency stop” button situated on the front of
the unit.

Harnessing the bandwidth potential of PCI Express, the
41-924 Extension Kit enables computers with a PCIe slot to
remotely control a PXI chassis via a high-speed interface. The
extension system operates in 32-bit/33 MHz configuration
and has complete end-to-end hardware and software
transparency for the host system. Hardware installed in the
PXI chassis operates as if it is installed in the host system,
requiring no additional drivers or software.
The host system can be separated from the PXI chassis by up
to 7 meters using a high-quality shielded twisted pair cable.
Controlling PXI™ with PCI Express®
Based on PCI Express technology, the PCIe-to-PXI Extension
Kit provides bus expansion capability through its high-speed
differential signal interface. With the 41-924 Extension Kit,
users can use a PCIe slot to control an external PXI chassis.
Because the PCIe bridge is transparent, there is no need to
install any additional software on the external chassis.
The Extension Kit consists of a 50-924-001 card installed in the
host computer, a shielded interface cable, and a 40-924-001
module installed in the remote PXI chassis. The 50-924-001 has
a PCIe x1 footprint and communicates with the 40-924-001 via
the interface cable. The 40-924-001 converts the PCIe interface
into a PCI interface for the PXI slots in the extension system.
The link between host PC and the external chassis is a PCI
Express X1 link that consists of a dual-simplex communications
channel with two, low-voltage differentially driven signal pairs.
The signaling rate can be up to 2.5 Gbps in each direction. With
a shielded twisted pair cable, the maximum extension distance
is up to 7 m without decreasing signal rate.
