RS232 Serial Camera Module

RS232 Serial Camera module
Description:
RS232 serial camera is new generation of serial camera module, which can be used to snapshot high-definition image through serial interface. Serial camera module get JPG image through a serial port, so this module can be easily integrated into the some device, and let the equipment device has image snapshot function.

Return: 7600360000
3, Read the data length of the captured image: 5600340100
Return: 76 00 34 00 04 00 00 XX YY
XX YY ------- picture data length, XX is the high byte, YY is the low byte
4, Read the picture data: 56 00 32 0C 00 0A 00 00 XX XX 00 00 YY YY ZZ ZZ
Return: 7600320000 (interval) FF D8...FF D9 (interval) 7600320000
00 00 XX XX ------ starting address (starting address must be a multiple of 8, generally 00 00)
00 00 YY YY ------ picture data length (high byte first, then low byte)
ZZ ZZ -------- interval (= XX XX * 0.01 milliseconds, preferably a small number, such as 00 0A)
Note: JPEG picture file data must begin with FF D8, and end with FF D9.
