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.
