II. Introduction
Wireless transceiver modules SRWF-1028 can be used in any standard or nonstandard user protocol.
The module has highly be avoided disturbance ability, long transmission range. In the open field the distance can reach 4500m (4800bps, use AT-6 antenna).
Low power consumption, Transmitting current 300～550mA, Receiving current 32～38mA.
The frequency is 403MHz/433MHz/470MHz/868MHz/915MHz.
User can order the channel. We can supply 8 channels normally. As the user needs we can design 16/32 channels also.
The module has TTL/RS232/RS485 interface, 7E1, 8N1, 7E2, 8E1, 8O1, 9N1 verify.
We can supply the 1200bps/2400bps/4800bps/9600bps/19200bps baud rate. Users can choose one of the baud rate as you want.
The user can also choose any antenna to match the modules.
