Pickering Interface 40-922 PXI Chassis is a fully
compliant 8 slot PXI chassis that can accept any 3U PXI
or cPCI module. The chassis is ideal for bench top use
or for use in a rack system.
The 40-922 includes all the features and performance
required by the PXI standard and supports a control
interface or embedded controller and up to 7 additional
3U peripheral modules. The control interface can be
provided by a Pickering’s 41-921 PCI to PXI interface
kit, allowing the chassis to be controlled from a PC.
The chassis is fitted with a 350W industrial grade
power supply mounted at the rear of the unit with
sufficient capacity to support PXI modules with very
high current demands.
An intelligent chassis management system monitors
the power supply voltage, internal temperature and the
cooling fan speed. The current condition of the chassis
is displayed on front panel status LEDs and can also be
monitored remotely via an RS232 port.
Two 60cfm fans insure maximum PXI module cooling
and an efficient direct convection design allows
the chassis to operate over an extended ambient
temperature range of 0°C to +55°C.
The low acoustic emissions make the chassis ideal for
applications such as office or laboratory environments
where noise levels are critical. The sound pressure level
varies between 41.6dB and 47.3dB dependant upon
the controlled fan speed which automatically responds
to the internal chassis temperature.
The 40-922 chassis can also be supplied with a
mounting frame to allow installation into a standard
19” rack. The frame increases the overall height to 5U
and allows space for cooling air to be drawn into the
underside and expelled from the top of the chassis.
The system slot is compatible with any PC-PXI bridge
and any 3 slot wide PXI controller.

SECTION 2 - TECHNICAL DESCRIPTION
BACKPLANE OVERVIEW
Interoperability with CompactPCI
The 40-922 is designed to be used with both PXI-compatible products and standard CompactPCI products. Its
backplane is compliant with PXI Specication Rev. 2.2.
The signals on Slot 1 of the backplane meet the requirements of the CompactPCI specication for both the peripheral
and system modules.
The PXI-specic signals are located on Slot 2 onwards. Signals that are reserved or not used in the CompactPCI
64-bit specication are used as PXI-specic signals. Therefore, peripheral modules that meet the requirements of
the CompactPCI 64-bit specication will function in the 40-922.
Note: Do NOT install CompactPCI peripheral modules which operate with rear I/O in 40-922 due to the possible
conict between rear I/O signals and PXI-specic signals on J2.
System Controller Slot
The System Controller slot is Slot 1 of the chassis as dened by the PXI specication. The 40-922 chassis can
accommodate a PXI system controller that occupies up to 3 slots width. As dened in the PXI specication, two
controller expansion slots allow the controller to expand to the left.
Star Trigger Slot
The Star Trigger (ST) slot is Slot 2. This slot has dedicated trigger lines between ST slot itself and slots 3 to 8.
The star trigger functionality is intended to provide a precise trigger signal to the peripheral modules by installing a
specic star trigger controller module in the ST slot. The star trigger slot can be also used as a general peripheral
slot if you do not need the star trigger functionality.
Peripheral Slots
There are 7 peripheral slots in 40-922 (including the Star Trigger controller slot). Each peripheral slot can
accommodate a 3U PXI/CompactPCI peripheral module.
Note: DO NOT install a 3U CompactPCI module with rear I/O function in the 40-922 chassis.
Local Bus
The local bus on a PXI backplane is a daisy-chained bus that connects each peripheral slot with its adjacent
peripheral slots to the left and right. Each local bus has 13 lines and can transmit analog or digital signals between
modules. It can also provide a highspeed side-band communication path that does not affect the PCI bandwidth.
In accordance with the PXI specication, the local bus connects all adjacent slots except slots 1 and 2.
Trigger Bus
The trigger bus is a 8-lines bus that connects all PXI slots in the same PCI segment. The trigger bus can be used to
provide intermodule synchronization mechanism. PXI modules can transmit trigger or clock signals to one another
through trigger bus, allowing precisely timed responses to asynchronous external events the system is monitoring
or controlling.
System Reference Clock
The 40-922 supplies the PXI 10MHz system reference clock (PXI_CLK10) to each peripheral slot for inter-module
synchronization. An independent buffer (having source impedance matched to the backplane and a skew of less
than 1ns between slots) drives the clock signal generated from a high-precision oscillator to each peripheral slot.
This common reference clock signal can be used to frequency synchronize multiple modules in a PXI chassis.

Connecting Safety Ground
WARNING
THE 40-923 CHASSIS IS DESIGNED WITH A THREE-POSITION IEC CONNECTOR THAT CONNECTS
THE GROUND LINE TO THE CHASSIS GROUND. TO MINIMIZE SHOCK HAZARD, MAKE SURE YOUR
ELECTRICAL POWER OUTLET HAS AN APPROPRIATE EARTH SAFETY GROUND THAT IS CONNECTED
WHENEVER YOU POWER UP THE CHASSIS.
IF YOUR POWER OUTLET DOES NOT HAVE AN APPROPRIATE GROUND CONNECTION, YOU MUST
CONNECT THE FACTORY WIRE SAFETY GROUND TO THE CHASSIS. TO CONNECT THE SAFETY
GROUND, COMPLETE THE FOLLOWING STEPS:
1. Connect a 16 AWG (1.3 mm) wire to a chassis grounding screw using a toothed grounding lug. The wire must
have green insulation with a yellow stripe or must be non-insulated (bare).
2. Attach the opposite end of the wire to permanent earth ground using toothed washers or a toothed lug.
!
INSTALLING THE PXI CHASSIS
Site Considerations
The 40-922 is designed to operate on a bench and is supplied tted with feet that allow the front of the unit to be tilted
upwards. It should be noted that there is an air intake in the underside of the chassis therefore it is important not to
allow any restrictions underneath the unit.
The chassis can also be mounted in a 19 inch rack on a suitable equipment shelf or using Pickering’s rack mounting
hardware 63-102-001. When mounted on an equipment shelf, the unit should be allocated 5U of rack space and
must have its bottom feet inplace to ensure the correct ow of cooling air.
Figure 3.1 - Front of the 40-922 PXI Chassis

Page 3.2 8-SLOT PXI MAINFRAME 40-922
pickering
SECTION 3 - INSTALLATION
Cooling Considerations
The chassis draws cooling air for the PXI modules through an intake in the underside of the chassis directly below
the PXI slots (see Figure 3.2). It is important not to block the passage of air into this intake.
Figure 3.2 - Underside of the 40-922 PXI Chassis showing air intake for the PXI modules.
The 40-922 expels cooling air through an exhaust vent in the top panel (see Figure 3.3 below). When the chassis
is in use, make sure that this outlet is not restricted in any way.
To maintain the correct internal air ow, ensure that all unused PXI module slots in the chassis have blank front
panels tted.

pickering SECTION 3 - INSTALLATION
Figure 3.4 - Left side of the 40-922 PXI Chassis showing cooling air inlet for the power supply
The 40-922’s internal power supply draws cooling air through an inlet in the left hand side panel and expels air
through an aperture in the rear panel (see Figures 3.4 and 3.5). During installation, It is important to ensure that
these vents are not restricted and any cabling is routed away from all air inlets and outlets.
Figure 3.5 - Rear panel of the 40-922 PXI Chassis, air outlet for the power supply’s cooling fan
is above the power input connector
Fan Speed Setting
The 40-922 uses variable speed fans to adjust the cooling level in the chassis. The normal setting is for the fan
speed to be automatically controlled, this ensures that for low thermal loads and ambient temperatures the fan
speed is slow resulting in low levels of acoustic noise. As the chassis temperature rises the fan’s speed will rapidly
rise to increase the cooling. In some circumstances the fans may cycle between high and low speeds.
For most applications users should use the automatic mode, however, if the chassis includes modules with high
power dissipation, such as powers supplies or very high capacity switches carrying large currents, users may need
to set the fan speed to the permanently high speed setting to lower the stress on the high power module. Using the
high speed setting is particularly important when just a few high thermal load modules are tted since these would
take longer to heat the chassis . The fan speed setting is accessible through the Chassis Management System and
requires the use of a RS232 serial port. Once set the fan speed mode setting is stored and will be automatically set
to the requested mode when power is applied to the chassis.

SECTION 3 - INSTALLATION
Rack Mounting The Chassis
The 40-922 can be tted into a standard 19 inch equipment rack using the optional 63-102-001 Mounting Kit. The
kit consists of a frame into which the chassis is mounted that increases the overall height to 5U and allows space
for cooling air to be drawn into the underside and expelled from the top of the chassis.
For instructions on how to assemble the rack mounting kit, refer to Appendix A.
WARNING: When tting into a rack it is important to provide adequate support using side brackets or
runners, the mounting holes in the front panel anges are designed only for securing the device in the rack
and must NOT be used to support the weight of the whole device.
