Introduction

Data collection between the master (concentrator) and slaves (slave devices) is performed via wireless transmission. All slave devices within a group collect data and transmit it wirelessly to the master, which then forwards it collectively to an upstream device (gateway or PC). The master module is primarily designed for secondary development integration, with functionality identical to that of a standard master. The master (concentrator) module receives measurement data from the slaves (slave devices) and forwards it to a PC or gateway via RS485 or RS232 (TTL) interface. Slave devices periodically collect measurement data and transmit it wirelessly to the master (concentrator) module. Supply voltage is selectable: 3.3V or 5V. Communication between the master (concentrator) and upstream devices uses the standard MODBUS-RTU protocol, with a default address of 0xFE (254).

Features

• Antenna comes with suction cup antenna by default; specify rod-type antenna when ordering if replacement is required
• L and N are AC220V power supply inputs for the concentrator; A and B are RS485 communication interfaces
• The master receives measurement data from slaves, forwards it to a PC or gateway via RS485 interface; slaves periodically collect measurement data and transmit it wirelessly to the master station
• Master station module dimensions and pin definitions support PCB size customization per user requirements
• Communication between master and upstream devices uses standard MODBUS-RTU protocol, default address 0xFE (254)
• Slave #1 register start address begins at 00201; each slave corresponds to 30 registers storing real-time data, slave numbers range from 1 to 200, calculation method: (slave number - 1) × 30 + 201 = slave start register address
• Energized status of the cable can be detected when the measured cable voltage exceeds 170V

Applications

• Data collection
• Data forwarding
• Secondary development
