SI4432-433MHz 470MHz- aluminum housing-SV6500-Mesh 5W mesh network RF module
SV-MESH series are ultra long-distance MESH network data transceiver modules, which adopts the high-performance Silicon Labs Chips. They have NODE and ROUTER working modes, can be as repeaters automatically. It is easy to build a network without a blind area or distance limitation. To avoid interference, SV-MESH provides 40 frequency channels and configurable Net ID. SV-MESH 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 PC or customer’s own device

Functional description:
Note:
1)When worked with TTL or RS232 interface, the serial port of modules should cross match with the serial port of customer’s device(TXD(A+) to RXD, RXD(B-) to TXD).
2)For RS485 interface, the serial port of module match the serial port of customer’s device(A to A, B to B)
3)The ground pin of the module and device should be connected together
Typical connection as below
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:
The CS and SET Pin is internally pulled up. Pull CS pin high or leave it open will make modules enter into working mode, the serial and RF are both in receiving mode then.
In NODE working mode, SV6500-MESH module stays in receiving mode and wait for the series signal and RF signal. SV6500-MESH module can connect with any device which is a standard TTL interface.
-
When the RF signal comes, SV6500-MESH module will check the input RF signals if there is any error, and then transmit the received data out via series port automatically if no errors found.
-
When one packet is transmitted successfully, the Red LED will blink once.
-
When one packet is received and verified with no problem, the Blue LED will blink once.
The easiest way to test the module is by using computer(PC software)
3.Router mode
When set as ROUTER, in working mode, SV-MESH module can repeat the RF signal in the same network automatically to extend the distance.
Normally, Router module is connected with the external power supply to keep a long time in receiving mode and repeat the signal to extend the range
1) To ensure the normal working of the ROUTER, the node should send the data with the minimal time interval between adjacent packets. The time interval is different from the data length, RF data rate and baud rate.
When the RF data rate is the same as the baud rate, and the data length is 56bytes, the minimal time interval as below:

FAQ:
A. Why module cannot communicate properly?
1) Check if there is a power connection error;
2) Check if the module is enabled (CS / SET both high);
3) Check if the band, channel, rate, NET ID has set to the same;
4) Check if the module is damaged(light is on?)
B. Why transmission distance is not as far as it should be?
1) Power supply ripple is too large;
2) The antenna types do not match, or not properly installed;
3) The surrounding environment is harsh, strong interference sources;
4) Surrounding co-channel interference;
C. Why receiving data incorrect?
1) Check if the interface compatible with the device;
2) Improper parameter settings.
3) The module data interface is bad.
