dSPACE DS814-09 Link Board

The dSPACE DS814-09 Link Board is an interface card designed for hardware-in-the-loop (HIL) simulations and rapid control prototyping (RCP) applications. It facilitates communication between host PCs and dSPACE Expansion Boxes, enabling spatial partitioning of the Peripheral High-Speed (PHS) bus across multiple I/O boards. The DS814-09 mounts directly within an expansion box and connects to compatible host PC link boards via high-speed serial, optical, or Ethernet connections.

## Technical Specifications

• **Model:** DS814-09
• **Data Transfer Rate:** Up to 100 MBit/s
• **Host PC Interface:** 16-bit ISA slot
• **Installation:** Slave interface card installed in dSPACE Expansion Box
• **Power Supply:** +5 V ±5%, 150 mA from PC
• **Physical Dimensions:** 158 × 80 × 18 mm (6.3 × 3.1 × 0.7 in.)
• **Form Factor:** Insert Link Card

## Key Features

• Supports multiple connection types—high-speed serial links, optical connections, and Ethernet (100 Mb/s technology)
• Enables distributed I/O architecture across expansion boxes without central PHS bus bottleneck
• ISA slot interface for legacy host PC integration
• Compatible with dSPACE Release 5.2 and later software
• Operates with Pentium III at 800 MHz minimum (Pentium 4 at 1.6 GHz or higher recommended)

## Typical Applications

• Distributed HIL test systems requiring spatial partitioning of I/O resources
• Real-time control prototyping with multi-box expansion architectures
• Systems requiring extended I/O connectivity beyond single-box capacity

## Compatibility & Integration

The DS814-09 functions as the expansion box endpoint and requires a complementary link board installed in the host PC (DS813, DS815, DS817, DS819, or DS821 depending on host interface type). This paired architecture enables flexible communication topology across dSPACE AutoBoxes and Expansion Boxes. The board integrates with dSPACE hardware-in-the-loop environments where PHS bus partitioning improves system scalability and real-time performance.
