Use Molex Woodhead SST-DN4-104-2 only in a host that supports the documented PC/104 interface, I/O-address window and 5 V supply. Preserve the configured channel identities, DeviceNet addressing and application data before replacement.
The official ordering table identifies catalog number SST-DN4-104-2 as Molex order number 112005-0048.
Important Notice: Confirm catalog number SST-DN4-104-2 and order number 112005-0048 before installation. Isolate host and network power, record both channel configurations, and validate each DeviceNet segment independently after commissioning.
The first document presents exact-model technical data and eight engineering questions. The second is Molex official literature covering ordering, host interfaces, memory, addressing, diagnostics and environmental limits.
Connect a PC/104 controller to two separately configured DeviceNet networks.
Exchange deterministic process data between the embedded host and networked DeviceNet nodes.
Collect DeviceNet process and diagnostic data through the shared-memory host interface.
Restore the same SST-DN4-104-2 order identity while preserving host addressing and both channel configurations.
Verify both SST-DN4-104-2 and Molex order number 112005-0048 before work.
Isolate PC/104 host power and both DeviceNet network supplies before removing the card.
Record the configured I/O base address, memory window and interrupt resources before replacement.
Confirm the +5 V DC supply is within +/-5% and can support the documented 600 mA typical draw.
Preserve the channel-one and channel-two DeviceNet identities, baud rates and node configurations separately.
Protect the card and PC/104 stack from electrostatic discharge and mechanical misalignment.
Keep operation within 0 to +55 deg C and 5 to 95% non-condensing humidity.
After energization, verify power, status and communication LEDs and test both DeviceNet channels independently.
