SV651 500mW Industrial anti-interference RF wireless data transmission module with TTL RS232 RS485
SV651 is an Industrial class & highly-integrated RF transceiver module, which adopts the high-performance Si4432 from Silicon Labs and industrial micro-controller. TTL / 232 /485 can be chosen corresponding to SV651-TTL / SV651-232 / SV651-485. SV651 has good sensitivity and 500mW output power to achieve long RF range and reliable RF communication. To avoid interference, SV651 provides 40 frequency channels and configurable Net ID. SV651 is flexible but easy to use, it comes with many parameters, such as frequency, data rate, output power, Net ID, Node ID. Users can configure the parameters through a PC or customer’s own device.

Operation
1) Power on Reset
After powered on reset, the TX LED (Red) and RX LED (Blue) will blink 3 times, The total reset
time is around 2s, as below:
Note:Contact us to customize if you want to shorten the POR time.
2) Sleep mode
After Power-on Reset, the module enters into sleep mode when the CS pin is pulled low. In this mode,
the current consumption is very small. In Sleep mode, the module can’t do any communication and
cant’ be set even Set Pin is pulled low. All the parameters will be kept unchanged in Sleep mode.
User can wake up the module by pulling high the CS Pin.
3) Working Mode
The CS and SET Pin is internally pulled up. Pull CS pin high or leave it open will make SV654 enter
into working mode.

FAQ:
Why module cannot communicate properly?
a) Check if the band, channel, rate, NET ID has set to the same;
b) Check if there is a power connection error;
c) Check if the module is enabled (CS high);
d) Check if the antenna connection is not correct;
e) Check if the module is damaged.
Why transmission distance is not as far as it should be?
a) Power supply ripple is too large;
b) The antenna types do not match, or not properly installed;
c) The surrounding environment is harsh, strong interference sources;
d) Surrounding co-channel interference;
Why receiving data incorrect?
a) Improper parameter settings;
b) The module data interface is bad.
