41-924-300 Compatible Cable: PCIe-to-PXI Remote Control Interface Guide
Understand how the 3 m high-speed interface cable links a host PC to a PXI chassis, why a standard CX4 or InfiniBand cable is not automatically interchangeable, and what engineers and buyers should verify before ordering a compatible replacement.
Quick answer: The 41-924-300 is a 3 m high-speed expansion cable used in the 41-924 PCIe-to-PXI remote control system. It connects the 51-924-001 PCIe interface card in a host computer to the 41-924-001 interface module installed in the system controller slot of a PXI chassis.
Important compatibility note: Do not select a replacement only because the connector resembles a CX4, InfiniBand 4X or external PCIe cable. Mechanical mating does not confirm the required pair mapping, polarity, sideband wiring, shielding, signal integrity or functional compatibility.

What Is the 41-924-300 PCIe-to-PXI Cable?
The 41-924-300 is a 3 m PXI remote control interface cable for the Pickering 41-924 system. It is described as a high-speed expansion cable for the PCIe-to-PXI remote control interface and is supplied as the standard cable length in the 41-924-001-KIT.
The cable forms the external physical link between a 51-924-001 PCIe interface card installed in the host PC and a 41-924-001 PXI interface module installed in Slot 1, the system controller slot, of a PXI chassis. It does not replace either interface card and is not an Ethernet, USB or camera-control cable.
41-924-300 Compatible Cable Assembly
High-Speed Screw-Lock Connector
Key distinction: "41-924-300" identifies a specific cable application and 3 m length. "CX4" or "InfiniBand 4X" describes a connector and cable form commonly associated with other high-speed systems. The names should not be treated as equivalent specifications.
How the PCIe-to-PXI Remote Control System Works
The 41-924 system extends a PCI Express connection from a host computer to a separate PXI chassis. The host card and PXI module bridge the two backplanes, while the external interface cable carries the high-speed differential link between them.
application
PCIe Host Link
The system uses a single-lane PCI Express link. Official documentation lists an effective signaling rate of up to 2.5 Gbit/s and describes the external channel as dual-simplex, using separate transmit and receive differential pairs.
Transparent PXI Expansion
The PCIe-to-PCI bridge presents hardware in the remote PXI chassis to the host system. The system documentation states that additional software is not required on the external chassis for the bridge itself.
Shielded External Cable
The interface depends on shielded twisted-pair construction, controlled pair routing and secure connector retention. These characteristics are essential for preserving signal integrity across the external link.
41-924-300 Compatibility at a Glance
The following table summarizes the published system requirements most relevant to cable selection. It should be used together with the target equipment model, original cable reference and an approved cable drawing.
| Compatibility Item | Published Requirement or Selection Note |
|---|---|
| Reference part number | 41-924-300 |
| Nominal cable length | 3 m |
| Host-side hardware | 51-924-001 PCIe remote control interface card |

PXI versus PXIe: This article concerns the 41-924 PCIe-to-PXI system. Do not advertise the cable as a general PCIe-to-PXI/PXIe cable unless compatibility with the specific PXIe remote-control hardware has been independently confirmed.
Is a Standard CX4 or InfiniBand Cable Compatible with 41-924-300?
Not automatically. A cable may use a connector body that looks like a CX4 or InfiniBand 4X assembly and still be electrically unsuitable for the 41-924 interface. The connector shell is only one part of the complete interconnect.
CX4-style cable assemblies have been used for InfiniBand, 10 Gigabit Ethernet, machine vision, HS-Link, Camera Link HS and external PCIe applications. These systems can require different contact assignments, active lane usage, polarity conventions, sideband signals and shielding termination. A cable that physically plugs in can therefore fail to establish a link or may operate intermittently.
| Comparison Factor | Generic CX4 / InfiniBand Cable | 41-924-300 Compatible Configuration |
|---|---|---|
| Connector appearance | May appear mechanically similar | Must mate correctly with 51-924-001 and 41-924-001 |
| Signal assignment | Defined by the original network, imaging or proprietary application | Must match the 41-924 remote-control interface requirements |
| Differential pairs | Lane count and routing vary by application | Transmit and receive pair mapping and polarity must be verified |
| Length | Many standard and custom lengths may exist | 41-924-300 is specifically the 3 m version |
| Performance proof | May be qualified for another protocol | Should be validated for continuity, pair assignment, shielding and target-system operation |
Engineering takeaway: Connector similarity can justify using the same manufacturing platform, tooling and shielded cable architecture. It cannot, by itself, justify a compatibility claim.
41-924-100 vs. 41-924-300 vs. 41-924-700
The three published accessory references identify the cable length. Selecting the shortest practical cable generally simplifies routing and reduces unnecessary cable exposure, but the installation must still provide adequate service clearance and bend radius.
| Part Number | Published Length | Typical Selection Scenario | Procurement Note |
|---|---|---|---|
| 41-924-100 | 1 m | PC and PXI chassis installed close together | Confirm that rack service loops and connector access remain adequate |
| 41-924-300 | 3 m | Standard kit cable and general test-system installation | Use this reference when replacing the standard 3 m assembly |
| 41-924-700 | 7 m | Greater separation between host PC and PXI chassis | 7 m is the maximum published connection distance for this system |
Custom-length caution: A cable can be manufactured to a requested mechanical length, but reliable PCIe operation should not be assumed outside the published 1 m, 3 m and 7 m options. Any non-standard length requires application-specific signal-integrity and functional validation.
What Must Be Verified in a 41-924-300 Replacement Cable?
A credible replacement program should define the complete cable assembly rather than relying on connector photographs alone. The following checks are relevant to engineering approval, incoming inspection and finished-cable testing.
Connector and Retention Hardware
Confirm connector shell dimensions, keying, mating orientation, screw spacing, retention-screw thread and backshell clearance at both equipment panels.
Pin-to-Pin Wiring
Approve a controlled wiring table. Verify each contact, unused position, ground connection and sideband circuit. Do not assume that a generic straight-through CX4 pinout is correct.
Differential-Pair Routing
Maintain pair integrity through the cable and connector termination. Verify transmit/receive assignment, positive/negative polarity, pair-to-pair consistency and minimized untwist length.
Shield Termination
Confirm pair shielding, overall foil or braid construction, drain-wire routing and low-impedance shell bonding. Shield continuity should be included in the inspection plan.
Mechanical Construction
Define overall length, tolerance, cable outside diameter, minimum bend radius, strain relief, jacket material, label location and packaging requirements.
Finished-Cable Validation
Perform continuity, open, short, miswire, polarity and shield-continuity tests. For the strongest compatibility evidence, complete a functional link test with the target 51-924-001 and 41-924-001 hardware.

Installation and Power-Up Sequence
The cable is part of a PCIe bridge system, so connection and power sequencing matter. The official user manual instructs users to secure both cable ends before power-up and warns against disconnecting the interface cable while the system is operating.
- Turn off the host PC and PXI chassis before connecting the cable.
- Connect one end to the 51-924-001 interface card in the host PC.
- Tighten the cable retention screws firmly.
- Connect the other end to the 41-924-001 module in PXI Slot 1.
- Check that both connectors are fully seated and the cable is routed without excessive bending or tension.
- Confirm the interface cable is connected and secured.
- Power on the PXI chassis first.
- Power on the host PC second so that the BIOS can identify devices behind the PCI bridge and assign resources during startup.
- Shut down and power off the host PC first.
- Power off the PXI chassis second.
- Disconnect the cable only after both systems are fully powered down.
Do not hot-unplug the cable: Disconnecting the interface cable after the host PC and PXI chassis are powered can cause system errors, data loss, a system hang or a crash. If an improper disconnection occurs, reconnect the cable and reboot both systems in the correct sequence.
When Should the 41-924-300 Cable Be Inspected or Replaced?
A failed chassis connection is not always caused by the cable, but the cable should be inspected whenever the link becomes intermittent, equipment has been moved or the connectors show physical damage.
Cable-Related Warning Signs
- Damaged or missing retention screws
- Bent metal shell or damaged mating face
- Cracked backshell or separated strain relief
- Severe kinks, crushing or repeated tight bends
- Intermittent system detection when the cable is moved
- Open, short, miswire or shield-continuity failure
Other Causes to Check
- Incorrect PXI module slot
- PXI chassis powered after the host PC
- Loose connector retention screws
- Fault in the 51-924-001 PCIe card
- Fault in the 41-924-001 PXI module
- BIOS resource-allocation issue
- Chassis power or backplane problem
Information for a Replacement Quote
- Original reference: 41-924-300
- Required length and quantity
- Target card and module model numbers
- Clear photographs of both equipment ports
- Original cable photographs and label
- Wiring drawing or sample when available
- Required electrical and functional tests
Diagnostic practice: Record the power-up sequence, LED status and whether the problem follows the cable when a known-good assembly is substituted. This helps separate cable faults from host-card, PXI-module, chassis or BIOS issues.
