Introduction

The SC20MPC 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 SC20MPC 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 1600x1200) JPEG images for storage or viewing.
The SC20MPC 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 8 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 SC20MPC 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

• Small size, low cost and low powered camera module for embedded imaging applications.
• 5V DC Power Supply (standard), optional 12V or wide voltage 9-36V per request.
• On-board EEPROM provides a command-based interface to external host via serial link.

SET IR-CUT FILTER If the SC20MPC camera is customized with IR-cut filter, the host can set the filter by issuing the following commands for day and night mode, no commands needed if the camera also comes with Spinel supplied infrared LED plate that can control the IR-cut filter switcher automatically, otherwise commands are needed.

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.
