RS485-LORA-M

Description

The RS485-LORA-M (relay support) module provides a transparent RS485 data interface, which can adapt to most standard or non-standard user protocols.

➤In the data transmission state, transparent data transmission is performed. In this state, the LORA module sends the device data received from the RS485 serial port directly from the air; all data received from the air is directly sent to the device from the RS485 serial port.
➤RS485-LORA-M is a LORA module that works in the “410-525MHz” frequency band, half-duplex communication, and supports data transmission when used as a relay.
➤According to the forwarding function, the serial port only supports RS485 signals.
Parameter
➤LORA module features: pure radio frequency module, supports sending and receiving data signals
➤LORA chip solution: SX1268 (cannot be used with SX1278 modules)
➤Working frequency band: 410-525Mhz, support ISM frequency band, the default is 433Mhz, channel spacing 2Mhz is appropriate
➤LORA transmission mode: half-duplex, transparent transmission
➤Modulation method: LORA modulation and demodulation technology
➤Transmission power: Maximum transmission power (factory default) 22dbm, generally the default is set to maximum
➤Communication interface: RS485 terminal) serial port
➤Serial port parameters: serial port baud rate 1200-115200, 14 serial communication formats
➤Air baud rate: about 300~31250, the smaller the air baud rate, the longer the communication distance, but the transmission rate is also slow
➤Working voltage: DC9-28V, recommended 12V or 24V, terminal wiring power supply, power supply anti-reverse connection
➤Current parameter
1. When waiting for DC12V, 15ma; when DC24V, 4ma
2. Transmit (momentary) When the transmit power is 22dbm, 50ma (DC12V), or 24ma (DC24V)
3. Receive (instantaneous) 22ma (DC12V) or 12ma (DC24V)
➤Data length: When the capacity of a single packet exceeds the 255Byte of the internal ring FIFO buffer of the module, it will be automatically packaged and sent; the maximum buffer capacity is 1024Byte
➤Communication distance: 3000m in clear open space (air baud rate 1200), installation height 2 meters above the ground
➤Working environment: Working temperature: -40~+85℃; Storage temperature: -40~+125℃
➤Antenna interface: RF-SMA suction cup antenna, characteristic impedance 50Ω
➤Size 80*30*50 (L*W*H, overall size except for antenna and DIN rail card holder, unit: mm)

The RS485-LORA-M wireless serial port digital transparent transmission module is a device that allows for remote communication between two devices using RS485 and LoRa technology. It has an RS485 interface on one side and a LoRa interface on the other and is capable of transparently transmitting data between the two. The module also supports a relay function, which means it can be used to control a device remotely by sending signals over the network. The RS485-LORA-M module is useful in situations where it is necessary to communicate with a device that is located a long distance away or in a hard-to-reach location. It allows you to transmit data over long distances without the need for physical cables or wires.
