Introduction

The SC50MPb serial camera is a 5 MP serial JPEG color camera module that performs as a JPEG

compressed still camera and can be attached to a wireless or PDA host. Users can send out a

snapshot command from the host in order to capture a full resolution single-frame still image. The

image is then compressed by the DSP and transferred to the host.

It can snap pictures at 2560*1920(default); 2560*1440; 2304*1296; 1920*1080; 1600*1200;

1280*960; 1280*720; 1024*768; 640*480 and they're pre-compressed JPEG images which makes

them nice and small and easy to store or transfer. Perfect for a data-logging, security, or

photography project. Startup time is 3.5 seconds.

Features

• Module dimension: 32(W) x 32(L) x 25(H)mm (the height may vary for different lens options)

• Image size: 2560*1920(default); 2560*1440; 2304*1296; 1920*1080; 1600*1200;

1280*960; 1280*720; 1024*768; 640*480

• Wide voltage and low power: Typical: 160mA@5V, Max: 400mA (when LED's are on)

• [email protected], 100mA@9V, 80mA@12V, 70mA@15V, 60mA@18V

• UART/TTL interface support up to 921600 bps, RS232 interface up to 230400bps (default

115200bps)

• WDR: 85DB

• Built-in JPEG CODEC

• Built-in lens, default 3.6mm lens, multi options

• VC0706 protocol compatible

Command Protocol (HEX format)

Once camera is powered up, it takes around 3.5 seconds to be ready for any commands, when

camera is initialized after the 3.5S delay, the camera outputs the following data, which means the

camera is ready for capturing images:

Version:PTC5M0 1.00

MEID_Num:00

ImageWidth:2560,ImageHeight:1920

1. GET VERSION：56 00 11 00

RETURN：76 00 11 00 0B 50 54 43 32 4D 30 20 31 2E 30 30

0B is the version data length 11.

50 54 43 32 4D 30 20 31 2E 30 30converts to character strings “PTC3M0 1.00”

Once the version is read, the camera is ready for communications. Version number might be different

due to regular upgrades.

2. RESET：56 00 26 00

RETURN：76 00 26 00

3. CAPTURE AN IMAGE：56 00 36 01 00

RETURN：76 00 36 00 00

Notes: when getting unclear images right after power-up, resetting or exiting power save mode,

please wait for 4s till the camera is ready for stable images.

4. READ IMAGE DATA LENGTH：56 00 34 01 II

RETURN：76 00 34 00 04 XX XX XX XX

II ----- 1 byte represents reading different image buffer, value ranges from 0 to 5, “0” represents the

current single image buffer, “1-5” represents continuous images triggered by motion detection or

capturing multi images command.

XX XX XX XX ----- image length

For example, send: 56 00 34 01 00 return: 76 00 34 00 04 00 01 4B C6

0x00014BC6 / 1024 means image data length is around 82.9K.

5. READ IMAGE DATA：56 00 32 0C II 0A SS SS SS SS LL LL LL LL 00 FF

RETURN：76 00 32 00 00 FF D8 。。。。。。 FF D9 76 00 32 00 00

II ---- 1 byte read different image buffer, value ranges from 0 to 5, “0” represents the current single

image buffer, “1-5” represents continuous images triggered by motion detection or capturing multi

images command.

SS SS SS SS ---- start address（the address must be times of 8，for example 00 00）

LL LL LL LL ---- the length of image data（high byte，low byte）

Notes: JPEG IMAGE DATA must start with FF D8 and end with FF D9.

If read all the image data at once, the start address shall be: “00 00 00 00”, the length to read is the

same as what data length item 3 above has read; the data read starts with “FF D8”, and ends with

“FF D9”.

If read the image data in multi attempts, the first start address shall be: “00 00 00 00”, each time after

the start address shall be the last frame’s end address.

Example:

Send: 56 00 32 0C 00 0A 00 00 00 00 00 01 4B C6 00 FF

Return: 76 00 32 00 00 FF D8 ... FF D9 76 00 32 00 00

56 00 32 0C 00 0A 00 00 00 00 00 01 4B C6 00 FF

It means read the image data from the address 0x00000000 with data length 0x00014BC6.

6. STOP CAPTURE：56 00 36 01 03

RETURN：76 00 36 00 00

7. SET IMAGE COMPRESSION RATIO：56 00 31 05 01 01 12 04 XX

RETURN：76 00 31 00 00

XX is default at value of 54, valid value ranges from 0x36 to 0x8f, the greater value the poorer image

quality and less image file size. Recommended values: 0x36 --- high image quality; 0x54 ---- good

image quality; 0x72 ---- low image quality. The changed value can get saved after power-off.

8. SET IMAGE RESOLUTION： (default: 1920 * 1080)

56 00 31 05 04 01 00 19 22 （160*120） RETURN：76 00 31 00 00 // image size is around 5kb

56 00 31 05 04 01 00 19 11 （320*240） RETURN：76 00 31 00 00 // image size is around 13kb

Note: after setting the desired image size, wait for 3 seconds and then the new setting would be

saved in flash. The actual file size is subject to the field complexity and depth of field.

in flash after power-off.

Warning: Please do not try to issue the commands on RS485 interfaced cameras for baud rates

over 115200bps, it will damage the camera immediately and the camera needs to be returned

to Spinel for repair at client’s cost.

10. CHANGE CAMERA ID ADDRESS: 56 YY 31 05 04 01 00 06 ZZ

RETURN：76 YY 31 00 00

YY ---- the current ID.

ZZ ---- the new ID you want to change to, range from 00 to FF.

For example, the current ID is 00 (also the default ID), in order to change it to 02, the host can issue

the command: 56 00 31 05 04 01 00 06 02

Return: 56 00 31 00 00

// once the ID has been successfully changed, the 2nd byte of each command therefore shall be 02.

// the reset command would be: 56 02 26 00

11. LED CONTROL (supported only when the LED’s is equipped on board):
