SV6500 MESH 433mhz /470mhz rf module kits TTL RS232 RS485  5W High Power Wireless Transceiver  8km Ultra-long   Network node  rf Module

Include in the package:

 1pcs SV6500-MESH-433mhz TTL interface rf module 

 1pcs SW433-XP1M Sucker Antenna

 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 network without blind area or distance limitation. To avoid the 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.

Electrical Specification

  Note: High quality 3.3V LDO is integrated, and Pin CS / SET is 3.3V interface. TXD/RXD is also 3.3V for SV6500.

Application circuit

The typical schematic circuit is as below:

Note: The ground pin of the module and device should be connected together.

Typical application: 

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 arround 2s, as below:

Note:Contact us to customize if you want to shorten the POR time

2.Working mode
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, SV-MESH module stay in receiving mode and wait for the series signal and RF signal. SV610-MESH module can connect with any device which is standard TTL interface.
When series signal comes, SV610-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, SV610-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)

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 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:

How to connect Antenna: The antenna is important in the communication. For this module, the match impedance is 50 Ohm. We have many kinds of antenna for customer to choose, please contact the corresponding sales engineer for help, or find the antenna in our website.

 Tips for antenna:

*Don’t close to the ground, metal, magnet, big current;

*If you are using the sucker antenna, pull the wire as straight as possible, the sucker foundation should stick with metal

1)  USB bridge board

Th        Tere are 3 type of USB bridge, which is SU108-TTL/ SU108-232 / SU108-485.SU108 -TTL is for TTL Interface, SU108-232 is for 232 Interface, SU108 - 485 is for 485 Interface. User should select the right USB bridge corresponding to the RF module.
