RS-485, CAN and Ethernet Communication Board Development
Add communication interfaces to existing controller boards, including transceivers, isolation, protection, drivers and board-to-board integration testing. For machine manufacturers who need to add networking interfaces to existing equipment.
Development Scope
Add communication interfaces to existing controller boards, including transceivers, isolation, protection, drivers and board-to-board integration testing.
- Who This Service Is For
- Machine manufacturers who need to add networking interfaces to existing equipment
- Deliverables to Agree
- Communication board design information, firmware and interface test records.
Project Inputs
Information is used to determine interfaces, implementation conditions, and scope of work.
- Existing motherboard interfaces, voltages, connectors and space dimensions
- Speed and cabling conditions for RS-485, CAN or Ethernet
- Isolation, electromagnetic environment, power supply and motherboard driver interface
Deliverables and Acceptance
- Delivery Documentation
- Communication board design information, firmware and interface test records.
- Versions and Reproducibility
- The delivery list records the target hardware, software version, build or deployment steps, interface configuration and test records to facilitate subsequent integration testing and maintenance.
- Check pin definitions, logic levels and transmit and receive timings
- Check the sending and receiving results under the agreed cable length and speed
- Test recovery after disconnection, bus exception and reconnection
The acceptance is carried out based on the equipment, version, environment, samples and indicators confirmed by both parties; the scope of source code and design documents, prototype materials, third-party fees and subsequent maintenance are listed in the project documents.
Frequently Asked Questions
Does adding a communication board require changes to the main board?
An add-on board can be evaluated when interfaces, power capacity and mounting space are available. Otherwise, the main-board interface or mechanical design may need changes. Schematics and prototypes establish the modification scope first.
What information is required to determine the scope of development?
Please provide: Existing motherboard interfaces, voltages, connectors and space dimensions; Speed and cabling conditions for RS-485, CAN or Ethernet; Isolation, electromagnetic environment, power supply and motherboard driver interface. Missing information can be addressed through interface checks or a focused feasibility test before the scope is agreed.
