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.

Power ON/OFF Sequence
To power-on the PCIe to PXI Extension Kit:

1. Ensure that the interface cable is properly connected to the host PC and PXI chassis.

2. Power on the PXI chassis first.

3. Power on the host PC
   Caution : DO NOT remove the cable after the system and PXI chassis are powered on. Disconnecting the cable while the system is running may cause unpredictable system errors and/or system crash.
   As the PCIe to PXI Extension Kit is a standard PCIe-to-PCI bridge interface, the BIOS will identify each device behind the PCI bridge and assign resource to each one during start up. Thus users have to power-on the PXI™ chassis first in order to get appropriate resources from the BIOS.
   To power down the PCIe to PXIe Extension Kit:

4. Power down the host PC.

5. Power down the PXI chassis.

Caution : DO NOT power down the PXI chassis until the host PC is powered off. If the PXIe chassis is powered off while the host PC is on, the host PC may hang or crash.

Status LED Indicators
The LEDs on the front panel of the 51-924-001 and 41-924-001 give power status information. The LEDs light up only when the following conditions are met:

• The extension cable between the 51-924-001 (Host PC) and 41-924-001 (Extension Chassis) is properly connected.
• The extension chassis is powered on.
• The host PC is entering its Power-On Self Test (POST).

Section 4 – Troubleshooting

This section describes frequently asked questions that may assist in solving minor problems that may be encountered.

Question : What is the maximum extension length of the 41-924-001-KIT?
Answer : Pickering provides an interface cable in a 3 meter length, maximum cable length is 7 meters.
Question : When using the 41-924-001-KIT, are there any additional drivers or software required to install?
Answer : It is designed to be a standard PCI Express®-to-PCI bridge. It is not necessary to install additional drivers or software for support.
Question : How many extension chassis can I connect to a host PC by using the 41-924-001-KIT?
Answer : Due to the point-to-point architecture of PCI Express®, only one PCI Express® Bus Extension Product can be supported by one chassis. However, users can select multiple extension chassis for different purposes. For example, a
4-slot extension chassis provides small and compact form factor while an 18-slot extension chassis provides more PCI slots. Theoretically, PCI specification allows up to 255 PCI bus segments. PCI Express® Bus Extension Products do not limit the bus segment number. The maximum PCI bus segments may limited by your BIOS or operating system.
Question : Are there any compatibility problems with the 41-924-001-KIT?
Answer : The 41-924-001-KIT is designed as a standard PCI Express®-to-PCI Bridge. During PC boot up, your PC BIOS will search devices and assign resources such as, I/O, memory space and IRQ number, to each device according to its algorithm. Although PCI specification allows up to 255 bus segments in a PC system, the BIOS may not assign the correct and/or proper resource to each device in some complex PCI systems.
Because the PCI Express® specification was released in 2002, most hardware and circuit board designers as of yet do not offer multiple PCI-to-PCI bridges. Most BIOS work for simple applications but may not work for multiple PCI bus segments and a variety of resource requests. We suggest customers choose PC equipment with Intel 945, 965 or later chipsets to
adjust for these issues.
Question : If I encounter compatibility problems, what should I do?
Answer : Because most compatibility problems come from PCI resource assignments, customers should consult their PC vendors or BIOS vendors for help. Updating to the most current BIOS version may also resolve PCI resources problems.
The following list are some indications that may help customers to deal with compatibility issues:

• Disable the onboard device functions of your host PC to release IO resources.
• Remove PCI devices plugged/installed in your host PC.
• Connect an extension chassis which is single bus segment to the host PC. Plug a PCI device to an extension chassis one by one and boot each in sequence to check if your host PC can accommodate the PCI device or not.
• You may try to plug the PCI Express® extension host card to a different PCI Express® slot.

Section 5 – Maintenance Information
