More Information

Overview Manuals Applications DeviceNet Networking Host Interface Performance & Efficiency

Features:

  • Provides two DeviceNet channels on a 16-bit PC/104 interface card.
  • Allocates 256 KB of shared memory to each network channel.
  • Uses isolated CAN interfaces with standard five-pin DeviceNet connections.
The current ordering configuration is SST-DN4-104-2, order number 112005-0048, the two-channel PC/104 DeviceNet card without the multi-server variant.

It allows an embedded host to exchange deterministic I/O and diagnostic data with two DeviceNet networks through the DN4 firmware and software interface.

Before stacking the card, reserve conflict-free memory and I/O windows, select interrupts, verify five-volt capacity, connect network power and retain both channel configurations.

Availability is subject to Apter Power inventory and sourcing confirmation.

  • Embeds dual DeviceNet connectivity in PC/104 machine-control computers.
  • Supports real-time I/O acquisition for robotics, material handling and semiconductor equipment.
  • Provides a compact platform for DeviceNet device development and network diagnostics.
  • The card supports master Group 2 client and slave Group 2 server operation.
  • DeviceNet rates of 125, 250 and 500 kbaud are selected to match the installed network.
  • Each isolated CAN channel uses shielded twisted pair and a five-pin network connector.
  • The 16-bit PC/104 bus follows PC/104 versions 2.3 and 2.4.
  • Each channel exposes shared memory through a selectable window below the one-megabyte boundary.
  • Eight I/O bytes are placed on an allowed even boundary in the published address ranges.
  • Two channels draw 600 mA typical from the regulated five-volt host supply.
  • Separate shared-memory resources let the host exchange process data without serial polling of each device.
  • The compact 95.90 by 90.20 mm board adds networking without a full-size PCI slot.
Description
SST-DN4-104-2 is the two-channel PC/104 card in the Molex Woodhead SST DN4 DeviceNet interface family. Its 16-bit PC/104 host connection follows versions 2.3 and 2.4 and presents separate network resources for two DeviceNet channels.

Each channel provides 256 KB of shared RAM, isolated CAN signaling and a five-pin DeviceNet connector. The interface supports master Group 2 client and slave Group 2 server operation at standard DeviceNet network rates.

The compact board serves embedded control, real-time data acquisition and machine-network diagnostic applications where a stackable PC/104 form factor is required. Memory windows, I/O addresses, interrupt selection, network power and firmware must be coordinated with the host.

Technical notes
SST-DN4-104-2 requires conflict-free PC/104 memory and I/O window settings; verify both channel maps before energizing the host stack.
