SV6500-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 network without blind area or distance limitation. To avoid the interference, SV6500-MESH provides 40 frequency channels and configurable Net ID. SV6500-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.
4 bytes Net ID
Default 2 bytes Node ID
Serial parameters configurable
TTL/RS232/RS485/USB for option

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
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 arround 2s, as below:
Note：Contact us to customize if you want to shorten the POR time
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 stay in receiving mode and wait for the series signal and RF signal. SV6500-MESH module can connect with any device which is standard TTL interface.
When series signal comes, SV6500-MESH module will check the input series signal if there is any error, and then transmit the received data out via RF automatically if no errors found.
When 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 using computer（PC software）
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 external power supply to keep long time in receiving mode and repeat the signal to extend the range
★To ensure the stability and correctness of communication, please notice the following tips:
1) To ensure the normal working of ROUTER, the node should send the data with minimal time interval between adjacent packets. The time interval is different from the data length, RF data rate and baud rate.
When RF data rate is the same as baud rate, and the data length is 56bytes, the minimal time interval as below:
