Echelon 35100 ISA Network Interface Card with FTM-10 SMX — LonWorks / LON Platform
Engineering Background
The Echelon 35100 is a full-featured ISA-bus LonWorks Network Interface Card (NIC) designed for PC-based LON network management, commissioning, and monitoring applications. Paired with the FTM-10 SMX free-topology transceiver module, this card enables reliable communication across mixed-topology LonWorks segments — making it a proven tool for building automation integrators, OEM developers, and system commissioning engineers.
Product Positioning
Targeted at engineers maintaining legacy LON infrastructure or developing LonWorks-based control systems, the 35100 ISA NIC provides a direct hardware interface between a host PC and a LonWorks TP/FT-10 network. It is compatible with Echelon’s LonMaker Integration Tool, LNS, and third-party LON network management software. Konmask.com supplies verified surplus units with full functional testing documentation available upon request.

System Architecture & Signal Flow
The 35100 ISA NIC operates as a LON network node from the host PC’s perspective. The onboard Neuron chip handles the full LonWorks protocol stack (Layers 1–6), communicating with the host via the ISA bus using Echelon’s Host Application Programmer’s Interface (HAPI). The FTM-10 SMX transceiver module connects to the TP/FT-10 twisted-pair network segment, providing differential signal transmission at 78 kbps. The host PC runs LNS or compatible software to issue network management commands, configure node variables, and monitor network health — all routed through the 35100 NIC as the network interface gateway.
Signal Flow: Host PC Application → ISA Bus → Neuron 3150 (HAPI) → FTM-10 SMX Transceiver → TP/FT-10 Network Segment → LON Field Devices

Technical FAQ
Q: Is the 35100 compatible with modern Windows operating systems?
A: The 35100 ISA NIC requires a physical ISA slot, which is not present on modern motherboards. It is designed for use with legacy industrial PCs or ISA-bus embedded systems running Windows XP/7 or compatible LNS environments. For modern PC integration, consider Echelon’s USB or PCIe LON NICs.
Q: Can the FTM-10 SMX transceiver be replaced or upgraded?
A: Yes. The FTM-10 SMX is a plug-in transceiver module. It can be replaced with other compatible Echelon transceiver modules (e.g., FTT-10A) if a different physical medium is required, subject to board compatibility.
Q: What is the maximum cable length for TP/FT-10 with FTM-10 SMX?
A: In a free-topology configuration, the total wire length is up to 500 meters. In a bus topology, up to 2,700 meters is achievable with appropriate termination.
Q: Does Konmask provide a certificate of conformance?
A: Yes. A certificate of conformance and inspection report can be provided upon request for B2B and OEM orders.
Q: Is this product RoHS compliant?
A: As a legacy surplus component, RoHS compliance status follows the original Echelon manufacturing specification. Please contact us for documentation if required for your compliance program.
