Transmit-Power The standard transmit power 500mW(27dB), users can customize power 1W(30dB); Receiving sensitivity: -123dbm(1200bps),-118dbm(9600bps) 2. Low power consumption DC5V Power, Receiving current <28mA, transmitting current <350mA; Sleeping current <20uA; DC7.5 or 9V for 1W Power. 3. Power model HR-1028 has three power- saving models: Awaken from Hardware, awaken from COM Port, Awaken from Air 4.IO control function HR-1028 has 2 I (control On/Off switch input), 2 OFF (control On/Off switch output), user can control remotely terminal without developing (the user need to customize this IO function) 5. ISM frequency band, no need to apply Frequency Carrier Frequency: 433MHz, also capable of 868/915MHz. 6. High Anti-Interference and Low BER (Bit error Rate) Based on the GFSK modulation mode, it adopts the efficient communication protocol. The actual bit error rate is 10 ～10 when channel bit error rate is 10 . 7. Long transmission distance The standard transmit power 500mW(27dB), within the range of visibility, the reliable transmission distance can >3000m (BER=10 /1200bps), and >2000m (BER=10 /9600bps) when place the antenna higher than 3m.. The standard transmit power 1W(30dB), within the range of visibility, the reliable transmission distance can >4500m (BER=10 /1200bps), and >3000m (BER=10 /9600bps) when place the antenna higher than 3m. 8. Transparent data transmission Transparent data interface is offered, which can be fit for nonstandard user protocol. Any false data generated in the air can be filtrated automatically (What has been received is exactly what has been transmitted). 9. Multi-channel and speed HR-1028 provides 8, 16 or 32 channels to meet the multiple communication modes of the users. Baud rate is 1200, 2400, 4800, 9600, 19200 and 38400bps. The wireless transmission speed and the connection baud rate are proportional, to satisfy the customer’s equipment. 10. Three kinds of interface modes (UART, TTL, RS232, RS485)UART, RS232, RS485 interface diversion chip, User can choose any of them.
