5 Mega Pixels Serial JPEG Camera SC50MPA User Manual, Rev. B (Oct 2018) For latest user manual, please visit: www.spinelelectronics.com

Introduction The SC50MPA Camera is a highly integrated serial JPEG camera module which can be attached to any host system that requires a JPEG compressed still camera for embedded imaging applications. The module uses a 1/4’’ CMOS color image sensor along with a JPEG compression chip that provides a low cost and low powered camera system. The module has an on-board serial interface (TTL/RS232/RS485) that is suitable for a direct connection to any host microcontroller UART or a PC system COM port. The SC50MPA camera is capable of outputting JPEG format images only. User commands are sent using a simple serial protocol that can instruct the camera to send high resolution (160x120 to 2592x1944) JPEG images for storage or viewing. The SC50MPA camera module comes in a compact form factor with a built in lens and PH 2.0 4Pin socket connector that provides easy access to both power and serial data. There are multi lenses available for this camera from Spinel. A 60 degree (Standard), a 150 degree, 120 degree, 90 degree, a 45 degree, a 30 degree, a 15 degree and a 8 degree. The SC50MPA ships with the 60-degree lens installed for standard order, other lenses can be installed in house before delivery for custom orders. There is a locking screw on the side of the lens mount, which is used to lock the focus in place once set, to prevent it from inadvertently being changed.

Features

TEST THE CAMERA WITH PC 1. Test with Spinel PC test tool The PC Test Tool can be downloaded from our website: www.jpegcamera.com, the application only supports window XP/7/8 as of now. The camera needs to have RS232 output or TTL to RS232 converter to connect to the serial port of the PC, or use a USB to TTL converter if the camera comes in TTL output and the computer doesn’t have a serial pot, please make sure select the default baud rate to ensure proper running. The following image illustrates the interface of the evaluation software.

2. TEST AND TROUBLESHOOTING



For any technical issue or error, please use “SSCOM serial debug tool” to test the camera and figure out the issue, the “SSCOM serial debug tool” and instruction can be downloaded from our website: www.spinelelectronics.com For questions regarding this user manual, please email to [email protected].
