ISM frequency band , requiring on application of frequency point.Carrier frequency of 433MHz(HR-1025 F433), 915MHZ(HR-1025 F915), 868MHz(HR-1025 F868).3. Long transmission distanceWithin the range of visibility, the reliable transmission distance is >4500 m 4. Transparent data transmissionTransparent data interface is offered to suit any standard or nonstandard user protocol. Any false data generated in the air can be filtrated automatically (What has been received is exactly what has been transmitted).5. Multi- channelThe standard HR-1025 configuration provides 8 channels. If the user needs, it can be extended to 16/32 channels, meeting the multiple communication combination mode of the user.6.Dual serial port, 3 interface modesHR-1025 provides 2 serial ports and 3 interfaces, with COM1 as the TTL level UART interface and COM2 as user defined standard RS - 232/RS - 485 interface (user only needs to plug/pull 1 bit short circuiter and energize it to make the definition).7. Low power consumption and sleeping functionFor receiving, current is <32mA, transmitting current is <550mA, and sleep current is <5uA.
