14-SLOT PXI CHASSIS 40-914
SECTION 2 - TECHNICAL DESCRIPTION
BACKPLANE
The 40-914 PXI chassis uses a 14-slot backplane which consists of 1 system slot and 13 peripheral slots (at 33 MHz)
with 20.32 mm (0.8 inch) board center-to-center spacing.
Key Features:
●Compliant with PXI specification R2.1.
●Two ATX sockets and screw terminals for +3.3V, +5V, ±12V DC output connection.
●10-layer PCB for accurate impedance control.
●ATX socket and screw terminals for DC output connection.
●64-bit PCI bus on J1 and J2, support N-1 bus-mastering I/O slots (N: Slots).
●System controller slot is located in slot 1.
●Trigger controller slot is located in slot 2, providing individual triggers to all other peripherals.
Interoperability With CompactPCI
The 40-914 backplane is interoperable with PXI-compatible products and standard CompactPCI products. This is an
important feature, as many PXI-compatible systems may not require components that do not implement PXI-specic
features. For example, you may want to use a standard CompactPCI network interface card in a PXI chassis.
The signals on the P1 connector 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 P2 and are only found on the signals that are reserved or not used in
the CompactPCI 64-bit specication. Therefore, all modules that meet the requirements of the CompactPCI 64-bit
specication will function in the 40-914.
System Controller Slot
The System Controller slot is located in Slot 1 of the chassis as dened by the PXI specication. It has three
controller expansion slots, which are used for system controller modules that are wider than one slot. As dened
in the PXI specication, these slots allow the controller to expand to the left to prevent the controller from using up
peripheral slots.
Star Trigger Slot
The Star Trigger (ST) slot is located at Slot 2. This slot has a dedicated trigger line between each peripheral slot
(see Figure 2.1). This slot is intended for modules with Star Trigger functionality that can provide individual triggers
to all other peripherals. However, if you do not require advanced trigger functionality, you can install any standard
peripheral module into this slot. Peripheral Slots - there are seven peripheral slots including the Star Trigger controller
slot. The Star Trigger Slot can also accept an external standard to replace the chassis reference clock, PXI_CLK10
supplied by the chassis.
Local Bus
The PXI backplane’s local bus is a daisy-chained bus that connects each peripheral slot with its adjacent peripheral
slots to the left and right, as shown in Figure 2.1.
For example, a given peripheral slot’s right local bus connects to the adjacent slot’s left local bus and so on. Each local
bus is 13 lines wide and can pass analog signals between cards or provide a high-speed side-band communication
path that does not affect the PXI bandwidth.
Local Bus signals may range from high-speed TTL signals to analog signals as high as 42V. Initialization software keys
adjacent boards to prohibit the use of incompatible boards. This software uses the conguration information specic
to each peripheral board to evaluate compatibility. This method is a exible way to dene local bus functionality that
is not limited by hardware keying.
Trigger Bus
The 40-914 includes the 8 trigger bus lines dened in the PXI standard to interconnect the system and peripheral
slots.

POWER SUPPLY
The 40-914 uses two hot swappable modular power supplies that have easy access from the front panel. Standard
versions are operated from the supply to the chassis which can be in the range of 90V to 260V AC. Optional power
supplies are DC operated from 36V to 72V (Option 1) or 18V to 36V (Option 2). The power supply modules provide
+5V, +3.3V, +12V and -12V DC to the PXI backplane.
When two power supplies are installed (standard conguration), either one is capable of supplying the entire system
power should the other one fail (providing the total PXI module load does not exceed the power capability of a single
power supply module). Users may insert or remove a redundant power supply from the system without interrupting
the system operation (provided the backplane load can be supplied from one power supply module). However, for
systems where the chassis is fully populated, it is recommended that the system is powered down prior to changing
a power supply.
In the event of failure, replacement power supply modules are available as spare parts from Pickering with the order
code: 44-910-003.

SECTION 3 - INSTALLATION & OPERATION
Page 3.3
pickering
14-SLOT PXI CHASSIS 40-914
INSTALLING THE CHASSIS
This section includes information on siting the chassis for the most effective cooling, as well as setting the fan
speed and connecting the saftey ground.
Site Considerations
The 40-914 is designed to operate on a bench or in an instrument rack. Determine how you want to use your 40-
914 and follow the appropriate installation instructions.
Apertures in the rear and along both sides of the chassis facilitate power supply and module cooling. As shown
in Figure 2-2, air enters through lters and fan inlets located in the lower rear of the chassis and exits through the
upper sections on both sides and through the rear.
Cooling Considerations
The area above and below the chassis should be kept clear to ensure the inlet and exhaust air paths are not
obstructed. The user should allow at least 0.5 U separation between the top and bottom of the chassis and the
other instruments in the rack.
If the chassis is placed above an instrument that vents hot air from its top cover then a mechanical separator, such
as a tray, should be used to stop the chassis from taking hot air into the chassis
The side and rear air exhausts should be kept clear of obstructions
Ensure that all unused slots in the chassis have ller panels installed, as required by the PXI standard, to ensure
the correct internal air ow.
Ensure the air lter on the bottom of the chassis is correctly installed after cleaning.

SECTION 3 - INSTALLATION & OPERATION pickering
14-SLOT PXI CHASSIS 40-914
FAN SPEED SETTING (40-914-101)
The 40-914-101 version of the chassis is tted with 4 fans that can each be set to one of three speed settings. For
ofce and laboratory use it is recommended that the medium speed setting is used. For use in a rack where higher
temperatures may be experienced and fan noise is less of an issue, the speed can be set to high. The low speed
setting should be used with caution in applications where there is low module power dissipation and no risk of the
chassis overheating. The following procedure describes the sequence for changing the fan speed. Note: Figures
3.2 and 3.3 show an 8-slot chassis with 3 fans, the procedure for a 14-slot chassis with 4 fans is basically the same.
1. Turn off power to the chassis and remove all cabling.
2. Place the chassis on its back (with PXI slots facing upwards) to gain access to the underside.
3. Remove the 5 crosshead screws securing the fan tray to the underside of the chassis - as shown in Figure 3.2.
4. Carefully lower the fan tray by pivoting it on its lower edge, taking care not to strain the wiring to the fan assemblies.
5. Locate the 2 fan controller boards mounted on the side of two of the fans - as shown in Figure 3.3.

6. Referring to the legend on the fan controller
boards, set the speed of each fan by
removing the link from its current position
and retting it to the required setting (each
board controls two fans). The legend on the
controller board is shown in Figure 3.4.
7. Ret the fan tray and secure with the 5
crosshead screws.
8. Return the chassis to its normal orientation,
ret all cabling and apply power.

14-SLOT PXI CHASSIS 40-914
INSTALLING PXI MODULES
CAUTION
WARNING - DANGER OF ELECTRIC SHOCK
BEFORE REMOVING A MODULE FROM THE CHASSIS ENSURE THAT ALL
CONNECTIONS TO THE MODULE ARE REMOVED
Electrostatic discharge can damage the components on the module. To avoid such damage in handling
the board, touch the anti-static bag to a metal part of the chassis before removing the board from the bag.
Ensure that there will be adequate ventilation for the module when tted into the chassis.
The module should be installed in accordance with the following procedure:
1. Do not attempt to install, or remove, modules with the user connection attached. The UUT should be electrically
and mechanically disconnected from the chassis.
2. Handle all PXI modules as you would any other static sensitive device. Ensure that the bag containing the PXI
module is at the same voltage as the chassis by touching both at the same time. Store any modules being
removed in a static protection bag.
3. Ensure that the system is turned OFF but still connected to mains so that it remains grounded.
4. Choose an appropriate slot in the rack.
5. Remove the blanking plate for the chosen slot.
6. Ensure that the injector/ejector handle is in its downward position. Align the module with the module guides on
the top and bottom of the slot.
CONNECTING THE SAFETY GROUND
WARNING
THE 40-914 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.

CAUTION
Do not raise the injector/ejector handle whilst inserting the module. The module will not insert properly
unless the handle is in its downward position.
7. Hold the handle whilst slowly sliding the module into the module guides until the handle catches on the
injector/ejector rail (refer to Figure 3.5).
8. 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.
9. Screw the front panel of the module to the front panel mounting rail.
10. Power up the chassis and wait for the green Ready light.

INSTALLING AND IDENTIFYING A PICKERING PXI CHASSIS IN NI MAX
Any non-NI PXI chassis will not be identied by manufacturer and model in MAX unless the appropriate les are
added to the controller system.
This lack of identication is not usually a problem, the chassis will appear as (Unidentied) in the MAX list, but this
should not affect its performance in any way.
In order to make MAX fully identify a Pickering chassis, follow these instructions:
If you are obtaining the conguration ini les from the Pickering “Software Installation” disk then ignore steps 1, 2 and
6a, alternatively if you are downloading these les ignore step 6b.
1. Copy the required .ini le from the download location to your PC using the following link:
http://www.pickeringtest.info/downloads/drivers/Chassis/
2. Copy the les to any convenient location on your PC, for example to the Desktop.
3. Launch MAX and expand: My System, Devices and Interfaces, PXI System.
4. The Pickering chassis will appear in the list followed by the word (Unidentied).
5. Right click on the entry and select: Identify As.
6a. Select the entry appropriate for the chassis, if it is not present, then select “Other” and browse to the location
of the le downloaded above.
6b. Select the entry appropriate for the chassis, if it is not present, then select “Other” and browse to the location
of your chassis .ini le on the Pickering “Software Installation” Disk, in the folder: “\Drivers_PXI\PXI Chassis
Identication”.
7. Change the le lter to “All Files (*.*)” and select the appropriate ini le.
8. The chassis should now be correctly identifed in MAX.
