Application:
- Robotics controll
- Home automation
- Power Supply Controll
- Other
Here are some programmable codes for control command :
1. Connect the lower computer to PC, HID will be
USB_VID 0x0416
USB_PID 0x5020
HID_CMD_SIGNATURE 0x43444948
2. Open device connection, the Host computer read lower computer IO state (This state is 16BIT, each byte stands for one state, the lowest is number 1, IO )
3. The control command of the host computer:
Open the first relay IO:0X0001, Close the first relay IO:0X0000
Open the second relay IO:0X0002, Close the second relay IO:0X0000
Open the third relay IO:0X0004, Close the third relay IO:0X0000
Open the first three relays simultaneously:. 0x0007
Close the second one, open the first and third one: 0x0005
Each bit stands for IO state, 1 for open, 0 for close!
