Product overview and where it fits
On vehicles, heavy equipment, and automated lines, the SimtoLink CAN FD to Ethernet bridge gateway puts CAN FD frames onto Ethernet either unchanged or mapped. Remote diagnostics, OTA, and a central waveform record sit on that path. The ARM platform can run filtering, DBC parsing, and extra stacks such as BACnet, subject to the software license.
SimtoLink supplies the bus termination, an isolated ground reference, and a baud-rate plan, together with a TLS1.2 policy and firmware signature checks. DIN-rail or in-vehicle mounts can be built to order in volume, and the isolated RS485 channels let conventional instruments sit in parallel on the same drop.
Reliability on site
For electrical safety and EMC, the gateway has passed the relevant CCC items. Ports include surge and reverse-polarity protection. Reinforced grounding and a partitioned layout reduce ground loops and common-mode noise. Outdoor or coastal sites can take a higher ingress rating and a corrosion-resistant coating.
Parameters can be loaded in batches, thresholds can be set, and the unit can keep event video or waveform records, depending on the model. Configuration and firmware go out by OTA. On site, close acceptance in three steps: a power-on self-test, clock sync on the link, and a spot check of samples. For metering or safety duty, SimtoLink helps submit the unit to a third-party metrology institute and supplies the type-test file.
Key hardware parameters
The figures below are the typical build of this gateway, for selection and for the technical clauses in a bid. A wider range, redundant power, or an intrinsically safe variant is available from SimtoLink with the Hardware Specification and the Installation and Commissioning Guide. Order codes in the family can differ slightly; the nameplate and the papers shipped with the unit govern.

| Ethernet | Single GbE | RSTP redundancy |
| Serial | 8×RS485 | Isolation 2.5kV |
| Wireless | Wi-SUN | External antenna |
| Protocol stack | BACnet/IP | Expandable |
| Operating temperature | -32～69 ℃ | Wide temperature |
| Supply | PoE+ | Redundant terminals |
| Mounting | DIN rail | Grounding required |
| Security | TLS1.2 | Firmware signature check |
Typical deployments
How this gateway is usually put to work on site, so a design can be chosen and the interface checked before rollout:
Commercial vehicles and construction machines
Engine, gearbox, and body CAN FD traffic goes to the cloud, so after-sales teams can diagnose remotely and pull a fault snapshot.
Line robots and AGVs
The control bus stays separate from the MES and SCADA Ethernet, which cuts interference from long CAN cable runs.
Storage BMS and EV chargers
Cluster CAN data is gathered into the energy-management system so events can be recorded in order.
Installation, grounding, and upkeep
- Before applying power, confirm the supply range and polarity. If there is any doubt, measure bus voltage and breaker capacity with a multimeter.
- Run the communications cable as shielded twisted pair, grounded at one end only, and do not lash it to high-power cables over a long route.
- For the first go-live, prove read and write in both directions and the threshold triggers against the platform in the lab, then move the gateway to site.
- Outdoors, give drainage and ventilation first priority, inspect the sealing faces on a regular round, and keep the lightning earth resistance inside the local code.
- In continuous service, spot-check samples and archive logs every 6 months.
Ordering, documents, and support
SimtoLink provides the hardware specification, an outline drawing, a wiring table, and a sample project. Volume orders can include a sample review and inspection at the factory. Warranty and calibration follow the contract and the documents that ship with the gateway.
