I. Basic Information

Model: PCIe-1427 (NI-1427)

Part Number: 779053-01

Bus: PCIe ×1 (Gen1, 250MB/s raw)

Camera Interface: Camera Link Base (1 port)

Pixel Clock: Up to 80MHz

Data Bandwidth: 225MB/s (effective)

Onboard Cache: 16KB FIFO

Status: EOL停产 (inventory / second-hand)

Driver： NI-IMAQ (traditional)， does not support IMAQdx

System： Windows 7/10 (32/64-bit)， Linux

II. Core Specifications (Easy to Understand)

✅ Camera Link Support (Only Base)

Configuration: Base (1×24-bit); Does not support Medium/Full

Splitter / Bit Depth (Valid Combinations):

1 Splitter: 8/10/12/14/16-bit, 24-bit RGB

2 Splitter: 8/10/12-bit

Maximum Resolution: 2048×2048@8-bit (80 MHz)

?? Trigger and Synchronization

External Trigger: 4 channels (15-pin D-SUB, ISO/TTL optional)

Encoder: 1 channel of orthogonal encoder input (position synchronization acquisition)

Synchronization Bus: RTSI (synchronized with DAQ / motion / CAN card)

Onboard Processing: ROI, binarization, LUT, downsampling

??️ Electrical and Physical

Connector: Camera Link MDR26 + 15-pin D-SUB (I/O/Trigger)

Isolation: Digital I/O 2500Vrms isolation

Power Supply: PCIe bus power supply (≈10W)

Temperature: 0°C ~ 55°C (operating)

Size: Full-height PCIe card (16.8×11.1cm)

III. Key Limitations (Must Read for Selection)

Only Base Mode: Does not support Medium/Full, maximum 80 MHz pixel clock

Limited Bandwidth: 225MB/s, prone to frame loss in high-resolution/high-frame-rate scenarios

Small FIFO: 16KB, requires reliance on system memory for large data streams

Driver Old: Only NI-IMAQ, does not support newer IMAQdx

No PoCL: Camera requires external power supply

IV. Typical Applications

Industrial Vision Inspection: PCB, semiconductor, electronic component appearance inspection

Scientific Imaging: Microscope, spectrometer, high-speed microscopy photography

Machine Vision Teaching / Experiment: Low-cost Camera Link entry-level solution

Maintenance of Old Systems: Replace the same faulty card to maintain the Base camera system operation

V. Alternative Models (Preferred Upgrade)

1) Direct Upgrade (Compatible with Base, higher performance)

PCIe-1430: 2×Base/1×Medium, 85 MHz, 400MB/s, in stock

PCIe-1433: 2×Base/Medium, 85 MHz, PoCL, in stock

2) Entry-level Replacement (Low cost, Base)

PCIe-1429: Base, 80 MHz, PoCL, IMAQdx, in stock

3) Network Camera Replacement (GigE Vision)

PCIe-8237: 2×GigE, IMAQdx, cost-effective high performance VI. Common Questions

⚠️ Only Base camera is supported: Medium/Full cameras cannot recognize

⚠️ High frame rate drop: Upgrade to 1430/1433 is required if the data rate exceeds 225MB/s

⚠️ Driver incompatible with new system: For Win11, choose 1429/1430 + IMAQdx as the priority option
