I. Basic Information

Model: PCI‑CAN/XS2 (Series 2, 2-port XS)

Part Number: 777499-02

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

Ports: 2 × DB-9 female connectors, each port independently configurable as XS

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

Status: EOL (around 2018)， second-hand / in stock circulation NI

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

II. Core Specifications (The main feature of XS: Software switching of 4 physical layers)

✅ 4 software selectable modes per port (Key difference)

High-Speed (High-speed): TJA1041, ISO 11898-2, 1 Mbps

Low-Speed/Fault-Tolerant (Low-speed fault-tolerant): TJA1054A, 125 kbps, bus fault automatic recovery

Single-Wire (Single-line): AU5790, 33.3 kbps, single-line vehicle network

External (External): Disable onboard transceiver, connect custom physical layer externally

?? Hardware and Electrical

Controller: Philips SJA1000 (CAN 2.0B)

Processor: Intel 80386EX (board-mounted, timing frame processing)

Isolation: Channel-to-bus 500 VDC optocoupler (2 seconds)

Terminal: No built-in 120 Ω, requires external terminal

Power Supply: +5 V, typical 900 mA (about 4.5 W)

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

Board Type: Full-height half-length PCI

Size: 20.7 × 11.18 cm (8.15 × 4.4 in)

III. PCI-CAN/XS2 vs Ordinary PCI-CAN/2

✅ XS2: 4 physical layer software switching; PCI-CAN/2: Fixed high-speed

✅ XS2: Compatible with high-speed/low-speed/single-line/external; PCI-CAN/2: Only high-speed 1 Mbps

✅ XS2: Supports multiple network adapters for old systems; PCI-CAN/2: Only standard CAN

⚠️ Both are EOL, both use NI-CAN drivers, both do not support CAN FD

IV. System Compatibility (Only legacy environment)

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

Not supported: Native Win10/11, Linux, NI-XNET, CAN FD

Software: LabVIEW (≤2017), LabWindows/CVI, C/C++, VB6

V. Typical Applications (Only for old equipment maintenance)

Multi-layer CAN network: Connect high-speed power CAN + low-speed vehicle CAN simultaneously

ECU testing for old models: Compatible with old single-line/low-speed fault-tolerant CAN bus

Upgrade of old production line: Replace the same faulty card, maintain multi-network communication

VI. Direct Replacement Model (Required, supports CAN FD + NI-XNET)

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

PCIe-8512/2: PCIe ×1, 2-port CAN/CAN FD, native Win10/11

PXI-8512/2: PCI-X bus version, suitable for chassis integration
