I. Basic Information

Model: PCI-CAN/2 (Series 2)

Part Number: 777357-02, 189063C-02

Bus: 32-bit PCI (5 V, 33 MHz), does not support PCIe

Ports: 2 × High-speed CAN 2.0, DB-9 connector (each port is independent)

Protocol: CAN 2.0A (11-bit ID), CAN 2.0B (29-bit ID), does not support CAN FD

Status: EOL (has been replaced by PCI-8512/2)

Driver： NI-CAN (traditional driver， not NI-XNET)

II. Core Specifications (Easy to Understand)

1) CAN Communication

Transceiver: Philips TJA1041 (ISO 11898‑2 high speed)

Baud Rate: 40 kbps ~ 1 Mbps (Standard CAN, no CAN FD)

Controller: Philips SJA1000 (CAN 2.0B compatible)

Processor: Intel 80386EX (board-mounted, handles timing frames)

Terminal Resistor: None built-in, requires external 120 Ω

Isolation: Channel-to-bus 500 VDC isolation (2-second withstand voltage)

2) Hardware and Performance

Onboard Memory: Small capacity (only basic cache, no 256 MB)

Transmission: Non-DMA, dependent on CPU interrupt (compared to 8512 with lower performance)

Synchronization: RTSI bus (7 channels triggered, 1 channel clock)

Connectors: 2 × DB‑9 (CAN_H=7, CAN_L=2, GND=3/6)

Board Type: Full-height half-length PCI card

Power Supply: +5 V, typical 850 mA (approximately 4.25 W)

Temperature: 0 °C ~ 55 °C (operating)

Size: 20.7 × 11.18 cm (8.15 × 4.4 in)

III. PCI-CAN/2 vs PCI-8512/2 (Key Differences)

Driver: PCI-CAN/2 = NI-CAN (old); 8512/2 = NI-XNET (new)

CAN FD: PCI-CAN/2 = ❌ Not supported; 8512/2 = ✅ Supported (2 Mbps)

DMA / Performance: PCI-CAN/2 = No DMA, CPU usage high; 8512/2 = DMA, zero-copy, low latency

Onboard Memory: PCI-CAN/2 = Small capacity; 8512/2 = 256 MB

Status: PCI-CAN/2 = End of Life (production discontinued); 8512/2 = Mainstream in stock

Price: PCI-CAN/2 = Second-hand / In stock; 8512/2 = New official price

IV. System Compatibility (only for legacy systems)

System: Windows 2000/XP/Me/98, LabVIEW Real-Time (old version)

Unsupported: Native Windows 10/11, Linux, NI-XNET ecosystem

Software: LabVIEW (old version), LabWindows/CVI, C/C++, VB6

V. Typical Applications (only for legacy scenarios)

CAN communication for old equipment: Industrial equipment, automotive ECU (only CAN 2.0)

Maintenance of old systems: Replace faulty cards of the same type to maintain old production lines / test benches

Basic bus monitoring: Packet capture, simple diagnosis, does not support CAN FD / high load VI. Common Questions

⚠️ PCIe cannot be used: Must use old-fashioned PCI slot; PCIe should be selected as PCIe-8512/2

⚠️ Driver compatibility issue: Windows 10/11 requires compatibility mode. It is strongly recommended to upgrade to 8512/2

⚠️ No CAN FD: New models / High-speed buses cannot be used; Must replace with 8512 series

VII. Direct replacement models (must be selected)

PCI-8512/2: PCI bus, 2-port CAN/CAN FD, isolation, NI-XNET, in stock

PCIe-8512/2: PCIe ×1, 2-port CAN/CAN FD, native support for Windows 10/1
