- 1 x Cable

Note: Please note that self-assembly is needed. Thank you!

Attention:
- For reading static pictures serial-control camera is connected via GND, RX, TX, and VCC.
- For analog video output, the CVBS port should be connected.
- TX and RX are the signals of 3.3V TTL Electric Level.
- When you use 5V to power the camera, the working current is around 100mA. So we recommend that a controlled switch to control the power supply.
- When it is used for the first time, please receive and send command after 2.5s.

Communications Protocol for the Camera (The numbers of command is hexadecimal)
1. Command to Reset: 56 00 26 00; Return: 76 00 26 00

3. Command to Read the Length of Photos: 56 00 34 01 00; Return: 76 00 34 00 04 00 00 XX YY
XX YY ---data length，XX for higher byte，YY for low byte
4. Command to Read the Data of Photos: 56 00 32 0C 00 0A 00 00 XX XX 00 00 YY YY 00 FF
Return: 76 00 32 00 00 FF D8…FF D9 76 00 32 00 00
00 00 XX XX ------start address(default: 00 00）
00 00 YY YY ------data length（higher one firstly then lower byte）
5. Command to Clear Photo Cache: 56 00 36 01 02; Return: 76 00 36 00 00
6. Command to Set Compression Ratio of Photos: 56 00 31 05 01 01 12 04 XX; Return: 76 00 31 00 00
XX recommend 36  （range:00 to FF）
7. Command to Set the Size of Photos:（default: 640*480）
56 00 31 05 04 01 00 19 11 （320*240); Return: 76 00 31 00 00
56 00 31 05 04 01 00 19 00 （640*480）
56 00 31 05 04 01 00 19 22  (160*120)
8. Command to Modify the Serial Buad Rate (Temporary):56 00 24 03 01 XX YY; Return: 76 00 24 00 00

XX YY         Rate
AE C8         9600
56  E4        19200
2A F2         38400
1C 4C         57600
0D A6        115200

Attention:
- Default baud rate: 115200
- With the baud rate modified, it will be 115200 when it is powered on again.

9. Command to Modify the Serial Baud Rate (temporary):56 00 31 06 04 02 00 08 XX YY; Return: 76 00 31 00

XX YY         Rate
AE C8         9600
