This document is an application note on the communication interface design of the ZNE module developed by Guangzhou ZHIYUAN Electronics CO., LTD. The document describes the scope of application, module introduction, and interface circuit design, including module power supply design, Ethernet interface, serial interface, etc.
The document describes the communication interface design for ZNE series modules, including Ethernet and serial interface circuitry. It is intended for developers integrating the ZNE‑10, ZNE‑10T, ZNE‑100, ZNE‑100T, ZNE‑100PT, ZNE‑100TI, ZNE‑200 and ZNE‑200T modules.
Key sections cover power supply requirements, Ethernet connector wiring (RJ45, 10BaseT/100BaseT), serial options (TTL, RS‑232, RS‑485), pin functions, and safety notes. The manual also provides a disclaimer and contact information for sales and service. This manual is written in Chinese.
| Supply voltage range | 48V~5.2V |
|---|---|
| Typical supply current | ≥100 mA |
| Ethernet speed | 10 Mbit/s (10BaseT) and 100 Mbit/s (100BaseT) |
The modules use an RJ45 connector that follows the 568B wiring standard.
A series limiting resistor should be placed on each communication pin, and pull‑up resistors can be added to TXD and RXD as needed.
