1 Product Introduction

The Wireless multi-connectivity self-organizing network photovoltaic motor communication module is a wireless communication product dedicated to industrial site collection and industrial equipment control. It supports relay communication and RS485 bus.

The product utilizes Ewei interconnection technology, combined with the interconnection base station, to support RS485 data collection and upload, and wireless transmission of device control information to designated devices.

It is applicable to sensor timing collection, PLC equipment control, and can achieve wireless control of multi-node devices in industrial sites based on sensor and control information. It also enables relay transmission to expand communication coverage, save wiring construction costs, and achieve wireless multi-point information collection and equipment control, thereby simplifying industrial site wiring, reducing implementation difficulty, and saving renovation costs.

2 Product Features

• RS485 Communication
• Supports 5V power supply and RS485 interface
• Application scenario: wireless on-site communication without wiring
• Supports relay communication

3 Main Application Scenarios

In conjunction with ZhiXinDa communication positioning base stations, it can achieve RS485 data collection and upload, as well as wireless device control information transmission. It is suitable for sensor timed collection and PLC equipment control. Based on sensor and control information, it enables wireless control of multi-node devices in industrial sites, reducing cabling costs, simplifying on-site wiring, reducing implementation difficulty, and saving renovation costs.

4 Block Diagram

A block diagram illustrates the components: a printed antenna (Frequency: 2402MHz~2480MHz, Modulation Mode: GFSK), a Bluetooth module (IN612L-Q1), a power supply module, an RS485 module (SP3485EN-L/TR), and an external interface. An internal debugging interface is also shown. The external interface includes connections for GND, +5V, 485B, and 485A. Crystals for 32MHz and 32.768kHz are connected to the Bluetooth module.

This device complies with Part 15 of the FCC Rules. Operation is subject to the condition that this device does not cause harmful interference.

This device is verified to comply with Part 15 of the FCC Rules for use with cable television service.

This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) This device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation.

Note: This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses, and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment causes harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures:

• Reorient or relocate the receiving antenna.
• Increase the separation between the equipment and receiver.
• Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.
• Consult the dealer or an experienced radio/TV technician for help.

This equipment complies with radio frequency exposure limits set forth by the FCC for an uncontrolled environment.

This equipment should be installed and operated with a minimum distance of 10 cm between the device and the user or bystanders.
