Feature: 1. High Performance: Adopt high receiving sensitivity (RSSI) and strong signal to noise ratio (SNR) optimization, with powerful anti interference technology. 2. Point to Point Mode 1: PC connection communication, 2 Lora modules support dual way data transceiver and mutual transmission under the same frequency. 3. Point to Point Mode 2: PLC interconnection mode, 2 Lora modules support dual way data transceiver and mutual transmission under the same frequency. 4. Point to Multi Mode: Any Lora module can be used as a master station, and other can be used as slave stations to collect sequentially device data under each Lora. 5. Relay Networking: Can realize multi level relay networking, for ultra long distance or complex environment networking, and run multiple groups of networks in the same area at the same time. Specification: Item Type: Wireless Transparent Transmission Module Model: LORA ETH Material: ABS LoRa Chip Solution: SX1268 LoRa Transmission Mode: Half duplex, transparent transmission Air Baud Rate: About 300-19200 Transmit Power: 20dbm Data Length: Cache 1024Byte Communication Interface: RS485 (terminal) LORA Module: Communication Interface: RS232, RS485, RS422 (the three communication interfaces are not independent of each other and cannot be sent and received at the same time) Baud Rate: 9600 by default; parity bit and stop bit can be set (through the host computer, up to 115200) Communication Distance: 5KM (open) Modulation Method: Lora (with FSK, OOK, GFSK) Transmission Rate: Lora mode, 0.2-37.5kbps Working Frequency Band: 410-525Mhz Data Transmission Method: Support stream mode and packet mode (convenient to use various applications) Streaming Mode: 1 serial port cannot send 1 Packet Mode: Wait for the serial port to be received once and then send it wirelessly Maximum Transmit Power: Maximum 20dbm (the larger the value, the farther the transmission distance) Receiving Sensitivity: -136dbm (the smaller the value, the farther the distance will be) Working Temperature: -40-85℃ Working Voltage: 12-36V (power supply through terminals).
