Feature of SRWF-508Low Power Data RF Module:
1. low power transmission with the transmission power of 30dbm/1W.
2. ISM frequency band , requiring on application of frequency point.
Carrier frequency of 433MHz(SRWF-508F433), 915MHZ(SRWF-508F915), 868MHz(SRWF-508F868).
3. High anti- interference and low BER(Bit error Rate)
Based on the GFSK modulation mode, the high- efficiency forward error correction channel encoding technology is used to enhance data's resistance to both burst interference and random interference and the actual bit error rate of 10-5 ~ 10-6 can be achieved when channel bit error rate is 10-2.
4. Long transmission distance
Within the range of visibility, the reliable transmission distance is >2200 m when the height is greater than 2m (BER=10-).
Within the range of visibility, the reliable transmission distance is >4400 m when the height is greater than 2m (BER=10-).
Within the range of visibility, the reliable transmission distance is >2300 m when the height is greater than 3m (BER=10-).
Within the range of visibility, the reliable transmission distance is >4500 m when the height is greater than 3m (BER=10-).
5. Transparent data transmission
Transparent 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).
6. Multi- channel
The standard SRWF-508configuration provides 8 channels. If the user needs, it can be extended to 16/32 channels, meeting the multiple communication combination mode of the user.
7.Dual serial port, 3 interface modes
SRWF-508 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).
8. Large data buffer zone
Interface 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).
9. Intelligent data control and the user doesn't need to prepare excessive programs
Even for semi duplex communication, the user doesn't need to prepare excessive programs, only receiving/transmitting the data from the interface. SRWF-508 will automatically, complete the other operations, such as transmission/receiving conversion in the air, control, etc.
10. Low power consumption and sleeping function
For receiving, current is <32mA, transmitting current is <550mA, and sleep current is <30uA.
11. High reliability, small and light
Single chip radio - frequency integrated circuit and single chip MCU are used for lessened peripheral circuit s, high reliability, and low failure rate.
