1. Safety
Intended application
PXI Express PXCe1008 series backplane are not end-products with independent functionality according
to the EMC regulations, an operational system is achieved only by combining the backplane with
appropriate plug-in PCI/PXIe instruments. As a consequence, formal certification requirements as for
instance the CE marking do not apply to it.
The completion and final testing of the units has to be carried out, or at least supervised, by a qualified
technician. The following instructions are directed exclusively to this qualified personal, i.e. engineers,
trained and qualified electricians etc.
Make sure that the finished system complies with the safety regulations currently applicable in the
country in which it will be used.

System controller slot
The system Controller slot 1 of the backplane is a 4-Link configuration system slot as defined in the CompactPCI
Express and PXI Express Specification.
The backplane connects the system slot using three PCIe X4 links to the peripheral slots. One PCIe link of the
system slot connects to a PCIe Switch using PCIe Gen 2 X1. The PCIe to PCI bridge provides PCI connection to
the PXIe hybrid slots and the PXI legacy slots.
The PXIe hybrid slots 3 and 4 are connected to the PCI Bus. The PCIe- to PCI bridge provides a 32-bit, 33Mhz
PCI Bus.
In order to support higher data rates on the PCI bus ask Hartmann Electronic to configure the PCI bus for 32-bit,
66 Mhz operation according to cPCI specification.
The system controller slot has also connectivity to PXI_CLK10, PXI Trigger Bus and PXI Local Bus 6.
The mechanical momentary switch at the front panel transitions the PWRBTN# from open-circuit to GND to open
circuit. The system board uses this ON/OFF state to control the PS_ON# signal. The PS_ON# signal turns on the
backplane’ main power supply.
PXIe peripheral slot
The backplane provides one PXIe peripheral slot. The peripheral slot is fully compliant with the PXI-5 PXI
Express Hardware Specification. The backplane connects the System slot using PCIE Gen2 X4 to the PXIe
peripheral slot. The PXI Express peripheral slot can accept the following modules:
-A PXI Express peripheral module.
-A PXI Express hybrid peripheral module.
-A CompactPCI Express Type-2 Peripheral module.
-A CompactPCI 32-bit peripheral with +5 V V(I/O).
PXIe hybrid peripheral Slots
The PXIe 3U 8 slot backplane provides 2 PXIe hybrid peripheral slots that are fully compliant with the PXI-5 PXI
Express Hardware Specification. The PXI Express hybrid peripheral slots can accept the following modules:
-A PXI Express peripheral module.
-A CompactPCI Express Type-2 Peripheral module.
-A hybrid-compatible PXI peripheral module that has been modified by replacing the J2 connector with an
XJ4 connector installed in the upper eight rows of J2. Refer to PXI Express specification for details. The
PXI peripheral communicates through the backplane’s 32-bit PCI bus.
24 pin ATX power Input connector
To provide power input into the backplane, the backplane is equipped with a 24 Pin ATX power connector, which
is fully compliant to the ATX specification.

www.hartmann-electronic.com Rev. 1.3 11
PCIe to PCI bridge module
The backplane features a PCIe to PCI bridge Module which translates the serial PCIe bus into the parallel PCI
bus. The PCI bus is needed for the connection to legacy PXI slots and devices. In order to support legacy PXI
slots as well as PXI Express fully Hybrid slots the PCIe-PCI Bridge Module is plugged between two device slots
at the rear side of the backplane.
The bridge Module is optimized for transfers from burst capable PCI Bus masters. The Module supports 32 bit 33
MHz operation as well as 32 bit 66 MHz operation.
PXIe clock module
The Hartmann Electronic PXI Express Clock Module generates clocks, according to the PXI Express Hardware
Specification, for the synchronization of PXI Express slot cards.
The PXI Express clocks are synchronized to an internal or external high accurate 10 MHz clock source. As soon
as an external clock source is available, the VCXO-based module, automatically synchronizes to the external
source. The switching between the clock sources is realized through automatic retrieve switchover. That allows
the PXI Express Chassis user to glitch free hot plug an external clock source to a running system.

Chassis management interface
(Not scope of delivery, see ordering information)
Hartmann Electronic PXI Express Backplanes provide the ability of expanding the Chassis Management
functions with the use of a custom specific PXIe Rear Module. This Module can be plugged into a connector at
the rear side of the backplane shown in figure 2-2.
The custom PXIe rear module can be equipped with various functions:
-PXI Star Trigger I/Os
-PXI(e) timing and synchronization input and output clocks
-Fan control, power On control
-Reset control, DB-9 power monitor connector
Contact Hartmann Electronic for further information.

PCI Express backplane diagram
Figure 2-4 shows the PXIe 3U 8slot series backplane’s PCIe interface.
Slots 2, 3 and 4 are connected to the system slot using PCIe X4. These slots have up to 2 GB/s (single direction)
dedicated bandwidth (X4 Gen-2 PCI Express).
Slots 5 and 8 are connected to the system by a PCIe to PCI bridge.
PXI Local bus
The PXIe backplane local bus is a daisy-chained bus, that connects each peripheral slot with adjacent peripheral
slots to the left and right.
The backplane routes PXI Local Bus 6 between all slots. The left Local Bus 6 from Slot 1 is not routed anywhere
and the right local bus signal from slot 8 is not routed anywhere.
Local bus signals may range from high-speed TTL signals to analog signals as high as 42 V.

www.hartmann-electronic.com Rev. 1.3 14
PXI Trigger bus
All slots share eight trigger lines.
Figure 2-5 shows the PXIe 3U 8slot series backplane’s Trigger interface.

www.hartmann-electronic.com Rev. 1.3 15
System reference clock
The PXIe 3U 8slot series backplane supplies PXI_CLK10, PXIE_CLK100, and PXIE_SYNC100 independently
driven to each slot.
PXI_CLK10, PXIe_CLK100 and PXIe_SYNC100 have the default timing relationship according to PXI-5 PXI
Express Hardware Specification.
The timing relations are as shown in Figure 2-6.
The 10 MHz reference clock input is derived from an internal clock oscillator.
Figure 2-7 shows the Clock architecture of the PXIe 3U 8slot series backplane.
The PLL is connected to the 10ppm 10 MHz clock oscillator. All clock outputs are synchronous to the 10 MHz
reference clock input through the oscillator.
Each of the clocks PXI_CLK10, PXIE_CLK100, and PXIE_SYNC100 are driven with independent buffers.

www.hartmann-electronic.com Rev. 1.3 16
Interoperability with CompactPCI
The PXIe 3U 8slot series backplane allows you to flexibly use the following devices in a single PXI Express
system:
-PXI Express compatible products
-CompactPCI Express compatible Type-2 peripheral products
-PXI hybrid slot compatible products
-Standard CompactPCI peripheral products
The PCI Clock has a frequency of 33 MHz. Therefore, the M66EN Pin of the CompactPCI bus is pulled down to
Ground at the backplane. Removing the pull down resistor will enable the 32 bit, 66 Mhz operation on the PCI
bus.
Ask Hartmann Electronic for further information on 66 MHz PCI bus signaling.

www.hartmann-electronic.com Rev. 1.3 17
3. Installation
Connecting backplane chassis ground
The backplane has a gold plated mounting area at the front side. The gold plated area must conduct to
the chassis’ extruded profiles in order to conduct the chassis to the chassis ground potential.
The backplane must be screwed to the extruded profiles from the rear side of the chassis.
It is strictly recommended to tighten the backplane to the extruded profiles with a screw, for each
available backplane mounting hole. That will increase the EMI performance of the Custom PXI Express
System.
Inspecting the backplane components
During the course of handling, shipping, and assembly, pins, shrouds, mounting screws, and other items
can become damaged and/or loose.
WARNING: Before utilizing the backplane, perform a thorough inspection to ensure
the backplane and its components are not damaged.
•To inspect the backplane:
1. Visually inspect the backplane to ensure that all of the connector pins are straight, screws are tight,
and so on.

www.hartmann-electronic.com Rev. 1.3 18
Installing hardware
The backplane is designed according to the 19” sub rack specification.
Care must be taken with the integration of the backplane into a third party chassis.
Follow the instructions of your system integrator in order to develop a chassis according to the effective
specifications.
