New Power Electric ANPE C-MBUS Communication Demonstration System User Manual

About this manual

The ANPE C-MBUS Communication Demonstration System is a hardware platform designed to showcase the C‑MBUS bus communication functions of New Power Electric's C‑MBUS chips (CMT100 and CMT001). It includes a concentrator, bus isolators, a communication module, and a PC‑based debugging software, allowing users to develop and test C‑MBUS devices.

The manual provides an overview of the system architecture, detailed installation steps, wiring diagrams, and operation instructions for each demo project. Appendices contain communication protocol specifications and circuit schematics for the module, concentrator, and RS‑232 interface. This manual is written in Chinese.

Frequently asked questions

What power source is required for the concentrator?

The concentrator needs a 24 V AC power source (AC24V/1A).

How many bus interfaces does the concentrator provide?

The concentrator offers three bus interfaces that are internally parallel.

What happens if the bus current exceeds the protection limit?

The bus isolator trips and disconnects the faulted branch when the current exceeds 500 mA.

Can the system operate without an external power supply?

Yes, the communication module can draw power from the bus, allowing operation without an external source.
