RF Module SRWF-507

SRWF-507, the low-power wireless transceiver data module is used as the wireless data transceiver in short-ranges, with the small size, weight and power consumption and good stability and reliability. Narrowband low power UHF wireless data transmitters and receivers with channel spacings as low as 25 kHz:
it is mainly used as following show:
*orienting the steel wheel
*Queue management system
*intellectual over-weight detecting system
* AMR  Automatic Meter Reading
* Wireless alarm and security systems
* 433 / 868 and 915 MHz ISM/SRD band systems
* Data radio can be used for Wireless conference voting system;
* Radio modem can be used for Sports training & competition;
* Wireless sensor Industrial wireless remote control and air conditioning remote controller;
* Observation and predication of oil well and hydrological information;
* Wireless RS232/RS485 conversion/connector;
* Point to multi-point wireless network, wireless on-the-spot bus and automatic data collection system;

Technical specification of SRWF-507:
1. Transmission power is 27dbm (500mW)
 2. Transmit distance is 3000m.
3. Center frequency is 433MHZ.
4. We have three Interface mode : UART TTL / RS-232 / RS-485. The details of how to connect the interface you can read the user manual.
5. Interface baud rate is 1200/2400/4800/9600/19200bps, you can only choose one of it when you buy it.
6. We use GFSK/FSK Modulation mode and use the high- efficiency forward error correction channel encoding technology so our modules have High anti- interference and low BER(Bit error Rate) feature.             
7. The standard SRWF-507 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.
8.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.Even for semi duplex communication, the user doesn't need to prepare excessive programs, only receiving/transmitting the data from the interface. SRWF-507 will automatically, complete the other operations, such as transmission/receiving conversion in the air, control, etc.
