Transmitter receiver RS485 433MHz. Transmitter/receiver module acting as a bridge between devices. Using the module, we can perform wireless RS485 transmission between devices. I support speeds: 9600/19200/38400/115200 Default port settings 9600 8 N 1. Very convenient if we do not have the possibility of positioning a typical wired RS485 bus. Configuration of the device using the commands "DIPSWITCH" The maximum number of devices is 32 modules. Attention! In order to establish a connection between devices, we need at least 2 modules! You can choose from 16 channels of operation (426MHz ~ 508.5MHz) in the transmitter and receiver you need to set the same channel (using DIPSWITCH). Working modes The device can operate in two main modes: Transmitter < -> receiver Transmitter < -> multiple receivers Technical parameters: Supply Voltage 8-25VDC Power consumption up to 2A ! RS485 interface Frequency: 433MHz Transmission Power: -40~+20dBm Receiver Sensitivity: -114dBm Operating temperature: -25 ℃ ~ + 75 ℃ Operating humidity 10-90 % Range up to 500m (for open space) Dimensions 80x50x31mm (without antenna) Note: Due to the light and screen setting difference, the item's color may be slightly different from the pictures. Please allow slight dimension difference due to different manual measurement.
