Product Introduction
If you are still running a Windows XP or Windows 7 industrial PC with a PCI slot, you have probably seen this card before. The SST 5136-DN-PC sits inside the PC and turns it into a DeviceNet node or scanner. It does not try to do everything in software. The DeviceNet stack runs in hardware, which matters when you need stable explicit messaging, change-of-state updates, and predictable network behavior.Engineers keep this card in service because it is simple and predictable. It supports the standard DeviceNet rates of 125, 250, and 500 Kbaud, handles nodes 0–63, and works with common DeviceNet I/O blocks, VFDs, barcode readers, and valve islands. The downside is obvious: PCI slots are disappearing, drivers are aging, and replacement stock is shrinking. If your machine still depends on it, treat it like a critical spare.
Quality SOP & Tech Pitfalls
The Lab Report (SOP)Incoming inspection checks the PCB revision, connector condition, EEPROM label, and PCI edge connector for corrosion or bent pins. On the test rack, the card is seated in a PCI slot, drivers are loaded, and the DeviceNet network is brought up at 125 Kbaud first, then 250 and 500 Kbaud. The scanner checks node presence, explicit messaging, and change-of-state behavior. Insulation and continuity checks cover the 5-pin DeviceNet connector and shield path. Firmware/driver version and test results are logged before anti-static packaging.The Engineer’s Warning (Pitfalls)Do not confuse 5136-DN-PC with 5136-DNP-ISA or 5136-DN-ISA. The ISA versions will not fit a PCI slot, and the driver packages are not interchangeable. I have seen a maintenance team order the wrong “DN” card because the paperwork only said “SST DeviceNet card.” The machine sat down for two shifts while someone chased the correct PCI version.Also, do not ignore the driver and SDK version. These cards usually depend on legacy SST / Woodhead / Molex software stacks. A Windows 10 upgrade can kill a perfectly good card if the driver is not validated. Test the exact OS image before you commit.
Installation & Configuration Guide
- Pre-Installation: Shut down the PC, disconnect power, and hold the power button for 10 seconds to discharge residual voltage. ⚠️ Take photos of the existing card, DIP switches if present, cable wiring, and DeviceNet trunk/drop layout.
- Removal: Remove the PCI slot retaining screw. Release the card carefully. Label the DeviceNet cable and any shield connections. Do not yank the 5-pin connector by the wires.
- Installation: Seat the new 5136-DN-PC firmly into the PCI slot. Reinstall the retaining screw. Connect the DeviceNet 5-pin cable with correct polarity and shield termination. Verify the network has proper termination at both ends.
- Power-On & Testing: Boot the PC. Install the correct SST/Woodhead/Molex DeviceNet driver and SDK. Confirm the card appears in Device Manager or the configuration utility. Set baud rate, node address, and scanner configuration. Test communication with at least one known DeviceNet device before returning the line to production.
Compatible Replacement Models
| Compatibility | Model | Notes |
|---|---|---|
| ✅ Drop-in Replacement | SST 5136-DNP-PCI | PCI-bus DeviceNet card from the same family; verify driver compatibility and exact suffix. |
| ⚠️ Software Compatible | SST 5136-DNP-CPCI | CompactPCI form factor; same DeviceNet function but requires different chassis. |
| ⚠️ Hardware Mod Required | SST 5136-DN-ISA / 5136-DNP-ISA | ISA bus cards; will not fit PCI slots and need different drivers. |
| ⚠️ System Upgrade Path | Modern Ethernet-to-DeviceNet gateway | Requires rewiring, new configuration, and possible PLC/HMI changes. |
Frequently Asked Questions (FAQ)
Q: Is the SST 5136-DN-PC still in production?
A: No. It is a legacy PCI DeviceNet card. Available units are typically New Surplus or used. Verify condition and driver support before purchase.Q: Can I use it on Windows 10 or Windows 11?
A: Only if the manufacturer provides a compatible driver and SDK for that OS. Many legacy SST DeviceNet cards were validated on Windows XP, Windows 7, or 32-bit systems. Do not assume plug-and-play.Q: Is 5136-DN-PC the same as 5136-DNP-PCI?
A: They belong to the same SST 5136 DeviceNet family and are both PCI cards, but the exact suffix matters. Check the label, revision, and driver package before treating them as identical.Q: Does it support 1 Mbps DeviceNet?
A: The CAN physical layer supports up to 1 Mbps, but standard DeviceNet networks commonly run at 125, 250, and 500 Kbaud. Use the rate that matches your existing network and cable length.Q: Can I hot-swap this card?
A: No. It is a PCI card inside a PC. The PC must be powered down before removing or installing it.Q: What if my PC no longer has a PCI slot?
A: Then this card is not a practical fit. Consider a verified replacement PCI card for a remaining PCI slot, or migrate to an Ethernet-to-DeviceNet gateway or CompactPCI/PCIe alternative depending on the host hardware.Q: Does it come with a warranty?
A: Legacy surplus cards are typically sold with a limited functional warranty, such as 30 days to 1 year, depending on the supplier. Confirm this before ordering.
