ISM frequency band , requiring on application of frequency point.Carrier frequency of 433MHz(HR-1021 F433), 915MHZ(HR-1021 F915), 868MHz(HR-1021 F868).3. Long transmission distanceWithin the range of visibility, the reliable transmission distance is >1200 m 4. Multi- channelThe standard HR-1021 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-1021 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. Large data buffer zoneInterface baud rate is 9600bps with format of 8N1/8E1 and user self- definition, allowing the transmission of long data frames at one time for more flexible programming by users. (If the user needs, it can also transmit the data in unlimited length at one time).7. Low power consumption and sleeping functionFor receiving, current is <30mA, transmitting current is <100mA, and sleep current is <3uA.
