9. Parameter and Working Mode Configuration

9.1 Device Address

9.1.1 Device Address Introduction

• DAM series device default address is 1
• Broadcast address 254 can be used for communication
• Address 0 cannot be used for communication
• Effective Device Address = Offset Address

9.1.2 Reading Device Address

After normal communication, enter initial device address as 254, then click "Configuration Parameters" in the software to read the current device address.



9.1.3 Setting and Reading Offset Address

Click "Read" or "Set" next to the offset address in the JYDAM debugging software to read or set the device's offset address.


9.2 Baud Rate Reading and Setting

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

11. FAQ and Solutions

11.1 RS232 Communication - Device Not Responding

Solution:
Device and host communication uses RS232 straight-through cable:

• RX to RX
• TX to TX
• GND to GND

11.2 Can Only Turn On, Cannot Turn Off

Troubleshooting:

• Check if the read address matches the actual device address
• Check if there are return commands in the debug information bar
• Verify if return commands are correct
• If address reading fails, no return commands, or abnormal return commands, check communication cables and communication converter

11.3 Multiple Devices on RS485 Bus

Important Notes:

• Each device address must be unique
• Cannot use broadcast address 254 when multiple devices are on the bus
• Broadcast address can only be used when there is only one device on the bus
• When more than 1 device exists, use DIP switch to distinguish addresses for control
• Otherwise, modules may not execute commands correctly due to communication data judgment synchronization issues
