ISM frequency band , requiring on application of frequency point.Carrier frequency of 433MHz(HR-1020 F433), 915MHZ(HR-1020 F915), 868MHz(HR-1020 F868).3. Long transmission distanceWithin the range of visibility, the reliable transmission distance is >800 m when the antenna height is greater than 3m (BER=10-3@1200bps). 4. Multi- channelThe standard HR-1020 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. 5.Dual serial port, 3 interface modesHR-1020 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).6. Low power consumption and sleeping functionFor receiving, current is <20mA, transmitting current is <40mA, and sleep current is <20uA.
