VI. Communication Protocol
1. Communication Basic Parameters
| Parameters | Value |
|---|---|
| Baud Rate | 9600 bps |
| Data bits | 8-bit |
| Stop bit | 1-bit |
| Parity check | No check |
| Check method | CRC-16/MODBUS |
| Polynomial | 0x8005 |
| Initial value | 0xFF |
2. Data frame structure
[起始符 0x55][设备地址（2字节）][功能码][数据地址][数据内容][CRC16]
Field description:
- Device address:
- IDUH(high byte): Superior device address, cannot be
0x00Or0xFF - IDUL(low byte): Local address, cannot be
0x00Or0xFF - Broadcast address:
0x0000(full control instruction, device does not return data) - Default address:
0xFEFE(effective after factory reset)
- Function code:
0x01: Read command (query status)0x02Write commands (configure parameters)0x03Control commands (on/off/stop, etc.)0x04: Request command (slave requests allocation of address)
- data addressDetermine the specific type of operation (see table below).
3. Core Instruction Lookup Table
Example defaults to0x12 0x34, but needs to be replaced with the target address

3. Write Command (Function Code0x02)
| Configuration Item | Data Address | Data Content | Example (Hexadecimal) |
|---|---|---|---|
| Set Address | 0x00 | New Address (2 bytes) | 55 00 00 02 00 12 34 50 7F(Set as0x1234) |
| Reverse Direction | 0x03 | 0x01Reverse) | 55 12 34 02 03 01 9D 5B |
| Close Hand Pull | 0x04 | 0x01Disable | 55 12 34 02 04 01 2C 9A |
4. Scenario Mode (A2/A3 Version Function)
| Operation | Data Address | Data Content | Example (Hexadecimal) |
|---|---|---|---|
| Set Scenario | 0x09 | 0x01~0x14 | 55 12 34 03 09 01 8D BD(Scenario 1) |
| Run Scenario | 0x0A | 0x01~0x14 | 55 12 34 03 0A 01 8D 4D(Run Scenario 1) |
| Delete Scenario | 0x0B | 0x01~0x14 | 55 12 34 03 0B 01 8C DD(Delete Scenario 1) |
4. Address Setting Process
- Slave Request Address:
- Press and hold the motor setting button for 5 seconds, the LED flashes twice, and then release.
- Slave sent:
55 FE 04 01 BB 14.
- Host assigned address:
- Host replied:
55 00 00 02 00 12 34 50 7F(assigned address is0x1234).
5. Precautions
- Calibration Requirements:
- Before using percentage control, it is necessary to perform a full open/full close operation to calibrate the stroke.
- is not calibrated (returns
0xFF), the percentage instruction is invalid.
- Broadcast instruction:
- Address set to
0x0000can control all devices in the group, but the devices do not return data.
- Error Handling:
- CRC Check Failed: Check the baud rate and terminal resistance (120 Ω should be connected at both ends).
- Motor overload: Reduce track resistance or check load.
6. Quick Reference Formula
