2. Connect Motor via bxi_usb2can

2.1 Connect Serial Port

Use a USB-to-Type-C cable to connect the debugger to your computer:

• Type-C side to the debugger
• USB side to the computer

Find the correct COM port:

• Windows: right-click Start icon 鈫?Device Manager
• Expand "Ports (COM & LPT)"
• Find the COM port under "USB Serial Device" (e.g. COM20, COM31)

Open bxi_tool, then select the corresponding port from the top-left port dropdown. If no port appears, click refresh.

2.2 Select Target

When the debugger is connected for the first time, it outputs a target selection menu:

• Input 1~8: communicate with the motor whose can_id matches that number
• Input 9: receive output from all motors on the CAN bus, and use the latest received can_id as output ID

Example: choose 9.

2.3 Connect Motor

Connect the motor and debugger through the 2+2 interface:

• Thicker wire: power line
• Thinner wire: signal line (red = H, black = L)

Recommended power input:

• Voltage: 24~48V
• Current: 3~5A

After power-on, observe motor serial output.

3. Serial Page

Used to view motor output and basic communication information.

---

4. Debug Page

Used for MIT control debugging, command sending, and status monitoring.

---

5. Config Page

Used to modify motor parameters and communication settings.

After connecting and powering on the motor, enter the left menu Config page to edit parameters.

5.1 CAN BUS Settings

Scroll down to the CAN BUS section to modify CAN communication parameters.

Key parameters:

• can_id: motor ID (the motor receives control frames sent to this ID)
• master_id: target sender ID (the motor sends feedback to this ID)

Common operations:

• Read ID: up arrow
• Write ID: down arrow

Rules:

• Writing can_id will also update master_id = can_id | 0x010
• master_id can also be written independently
• If you want to change only can_id while keeping a specific master_id, write master_id again after updating can_id

5.2 Save Parameters

To keep parameters after power-off, use the "Save Parameters" button at the bottom-right after modification.
