4. 1 active small light bulb;

5. Antenna (TX433)*2;

6. 1 USB to RS485 converter;

7. Several communication cables;

8. 1 computer;

Software preparation

The E860-DTU (8080-400SL) configuration tool can be downloaded from the corresponding location on the Ebyte official website;

Product wiring and configuration preparation

Equipment wiring

1. Connect the A and B interfaces of the RS485 converter to the A and B interfaces of the synchronous switch, as shown in the figure:

2. Next, connect the synchronous switch to the power supply. The positive pole of DC8~28V is connected to the DC 8~28V (V+) of the synchronous switch, and the negative pole of DC8~28V is connected to the DC 8~28V (V-) of the synchronous switch, as shown in the figure. :

Device connection configuration tool

1. Connect the RS485 converter to the computer and open the configuration tool of the synchronization switch, as shown in the figure:

2. Select the corresponding serial number in the "Serial Port" of the configuration tool. Then click "Open Serial Port" and click "Read Parameters". A prompt box will pop up, indicating that the parameters have been read successfully, which means the connection is successful, as shown in the figure:

Note: When using the USB to RS485 converter for the first time, you need to install software and drivers. Please consult the relevant manufacturer for detailed usage.

3. Use the host computer to configure the parameters of the two synchronous switches to be consistent (including basic functions and advanced functions, this demonstration only demonstrates the 1-to-1 mode), as shown in the figure:

4. In addition to the master and slave machines needing to be set inconsistently, the DIP switches of the two synchronous switches need to be configured to be consistent in terms of channel, jog, self-locking, one-way, and two-way (after that, our equipment will have a master and a slave) The difference is that in unidirectional mode, the host can only control the slave, and the slave cannot control the host. Switching to bidirectional mode allows bidirectional control), as shown in the figure:

Equipment input and output wiring

1. Connect the self-locking switch to the synchronous switch (simulating the input source on site). We will connect the two wires of the switch to the switch public terminal and switch input 1 of the synchronous switch host, as shown in the figure:

2. Connect the active small light bulb to the synchronous switch (simulating the controlled source on site). We will connect the two wires of the active small light bulb to the common end and off output 1 of the switch output 1 of the synchronous switch slave machine respectively. The usual starting point is as shown in the figure:

3. After connecting the input and output terminals of the two synchronous switches to the corresponding equipment, we connect the TX433 antenna (which can effectively increase the communication distance) to the master and slave machines of the synchronous switch respectively, as shown in the figure:

Communication Demonstration

1. Power on the two synchronous switching devices respectively. After powering on, the POWER light is always on. After the two devices are successfully connected, the RSSI indicator light will light up. The more RSSI indicator lights light up, it proves that the communication environment is better, as shown in the figure. Show:

Note: It is recommended that devices be at least 2 meters apart during communication.

2. Next, when we press the switch button on the synchronous switch host, we can find that the input 1 indicator light lights up, and then the output OUT1 indicator light of the synchronous switch slave machine lights up. At the same time, the relay of the switch output 1 of the slave machine is closed, and the small light bulb lights up. ;At the same time, the synchronous switch host will receive the controlled success signal fed back by the synchronous switch slave, and the OUT1 indicator light of the synchronous switch host will also light up, as shown in the figure:

After the above simple demonstration, we have completed the entry-level configuration and communication routines of the E860-DTU (8080-400SL) product. This equipment can also be used in many scenarios, such as: automated factory control, water pump motor control, warehouse alarm monitoring, sprinkler irrigation, etc.
