Interface Description

Wiring Instructions

RS485 cascade connection method

The built-in serial port of a computer is usually RS232, which requires a 232-485 converter (active isolated converters are recommended for industrial environments). After conversion, RS485 is connected to two wires, A and B. A is connected to terminal A on the board, B is connected to terminal B on the board, and the 485 shield can be connected to GND. If there are many devices, it is recommended to use twisted pair shielded wires and adopt a chain network structure.

Interface

Communication testing

① Select the current serial port number of the device and open the serial port;

② Select the corresponding product model;

③ Change the device address to 254, click "Read Address", and the software will prompt "Read Successful" at the bottom. If the device address read is "0" and the send and command in the lower right corner of the software are correct, it means that the device has successfully communicated with the computer.

Device Address

1.1 Introduction to Equipment Address
The default address for DAM series devices is 0, and communication using broadcast address 254 is not possible with 0.
Device address=dip switch address+offset address.
Note: This device does not have a dip switch, so the device address=offset address.
1.2. Reading device address
After the device communicates normally, write the initial device address to 254, and then click "Read Address" above the software to read the current address of the device.

1.3 Setting and Reading of Offset Address

Click on "Read" or "Set" below the offset address in the DAM debugging software to read or set the offset address of the device.

1.4. Reading and Setting of Baud Rate

Click on "Read" and "Set" in the baud rate settings bar below to read and set the baud rate and address respectively. After the operation, you need to restart the device and modify the computer serial port settings.

Introduction to Working Mode Functions

1.1 Sequential Start Mode

All relay modules containing more than 1 relay have this working mode, in which the relays will start in sequence according to the delay configuration parameters after each power on.

This mode is mainly used to alleviate the problem of high-power impact at the moment of power on, similar to LED large screens. After using this mode, the LED modules will start in sequence after each power on, without causing electrical ignition or high-power impact on the power grid causing voltage drop. It has the same effect when applied to other clustered installation electrical equipment.

Configuration parameters: interval time, waiting time

1.2. Flow cycle mode

This mode is similar to the cyclic version of the "sequential start" mode, which means that after power on, all relays are sequentially closed according to the delay configuration parameters. After all relays are closed, they start to disconnect from the first relay, and after all relays are disconnected, they start to close again from the first relay.

In this mode, controlling the landscape lights can achieve the effect of turning on and off flowing water. However, due to the mechanical spring structure inside the relay, the relay generally has a lifespan of about 100000 actions, which may slightly decrease when carrying high-power loads. Therefore, this mode is not suitable for long-term frequent use, otherwise it will reduce the service life of the entire module.

Configuration parameters: interval time, waiting time

1.3. Running cycle mode

The relay board in this mode will start to pull in and disconnect from the first relay after each power on, with an interval of the configured delay time. Namely:

Relay 1 on ->Delay time ->Relay 1 off, Relay 2 on ->Delay time ->Relay 2 off, Relay 3 on ->Delay time -> .....

In this mode, there is always a relay closing at any time, but like the two cyclic action modes mentioned above, this mode also has a short lifespan, so it is not suitable for long-term frequent actions.

Configuration parameters: interval time, waiting time.

1.4. Working mode function settings

Open the "DAM Debugging Software" and click on "Read" and "Set" in the working mode settings bar below to read and set the working mode separately.

Flash on/off function and settings

1.1 Introduction to Flashing and Breaking Functions

Manual mode: For each operation of the relay, the relay will flip once (open when closed, close when open);

Flashing mode: For each operation of the relay, the relay will close for 1 second (actual time =set number * 0.1) and then automatically disconnect;

Flashing mode: For each operation of the relay, the relay will disconnect for 1 second (adjustable time) and then automatically close;

1.2. Flashing and disconnecting settings

Open the "Juying Soaring DAM Debugging Software" and click the dropdown arrow behind the relay mode to select the mode. (The later time can be set by yourself, actual time=fill in the number * 0.1 [unit: second])

Note: The flashing and disconnecting mode cannot be written into the device chip. After selecting the flashing and disconnecting mode in the software, all channels are in flashing and disconnecting mode. Single channel control can be achieved by sending a flashing and disconnecting command for a single channel, without affecting the normal control of other channels.

Modbus Register Description

This control card is mainly a coil register, which mainly supports the following instruction codes: 1, 5, 15

Instruction generation instructions

Application example and explanation: In addition to offset address, the default broadcast address for the local address is 254. When there is only one device on the bus, there is no need to worry about the dip switch address. Simply use the 254 address. When there are multiple devices on the bus, select different addresses through the dip switch and send control instructions based on address differentiation.
Note: The RS232 bus is a 1-on-1 bus, which means there can only be two devices on the bus, such as a computer and a relay board. Only the 485 bus can mount multiple devices.
The instructions can be obtained through the debugging information of "Juying Soar DAM Debugging Software".
