µCAM – II Serial Camera Module
1. Description
The uCAM-II (microCAM-II) is a highly integrated
serial camera module which can be attached to any
host system that requires a video camera or a JPEG
compressed still camera for embedded imaging
applications.
The module uses a CMOS VGA colour 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) that is
suitable for a direct connection to any host micro-
controller UART or a PC system COM port.
The uCAM-II is capable of outputting both RAW
format and JPEG format images.
User commands are sent using a simple serial
protocol that can instruct the camera to send low
resolution (80x60 to 160x120) single frame raw
images for viewing or high resolution (160x128 to
640x480) JPEG images for storage or viewing.
The uCAM-II comes in a compact form factor with a
built in lens and a 5-wire connector that provides
easy access to both power and serial data.
There are 3 lenses available for this camera from 4D
Systems. A 56 degree (Standard), a 76 degree, and
a 116 degree. These are available to purchase from
4D Systems separately if required. The uCAM-II
ships with the 56 degree lens installed.
There is a locking nut on the barrel thread of the
lens, which is used to lock the focus in place once
set, to prevent it from inadvertently being changed.
2. Features

µCAM – II Serial Camera Module
4. Pin Descriptions
VCC pin 1 (uCAM-II Supply Voltage Input):
Module supply voltage input pin. This pin must be
connected to a regulated supply voltage.
4.5V to 9.0V DC range, nominal 5.0V.
TX pin 2 (Serial Transmit):
Asynchronous Serial port Transmit pin, TX. Connect
this pin to host Serial Receive (Rx) signal. The host
receives data from the uCAM-II module via this pin.
This pin outputs 3.3V logic.
RX pin 3 (Serial Receive):
Asynchronous Serial port Receive pin, RX. Connect
this pin to host Serial Transmit (Tx) signal. The host
transmits data to the uCAM-II via this pin. This pin
is 3.3V Logic however is 5.0V tolerant.
GND pin 4 (uCAM-II Ground):
Module ground pin. This pin must be connected to
ground.
5. Serial Interface - UART
The uCAM-II has a dedicated hardware UART that
can communicate with a host via this serial port.
This is the main interface used by the host to
communicate with the module to send commands
and receive back data. The primary features are:
• Full-Duplex 8 bit data transmission and
reception through the TX and RX pins.
• Data format: 8 bits, No Parity, 1 Stop bit.
• Auto detect specific Baud rates from 9600
baud up to 921600 baud.
• Selectable Baud rates up to 3686400 bps.
The uCAM-II has low voltage serial TTL levels which
can be directly interfaced to a micro-controller. The
voltage levels could be converted to RS-232 through
an external TTL to RS-232 converter to interface it
to any RS-232 port such as the one on the PC.
Please note that while the baud rate can go up to
3686400 bps, not all RS232/RS485/TTL USB
adaptors/cables can go this high. Please ensure
your hardware can handle the rate you want to use.
Please refer to sections 5.3 and 5.4 for more
information.
5.1. Single Byte Timing
A single byte serial transmission consists of the
start bit, 8-bits of data followed by the stop bit. The
start bit is always 0, while a stop bit is always 1. The
LSB (Least Significant Bit, Bit 0) is sent out first
following the start bit. Figure 3.1 shows a single
byte transmission timing diagram.
Figure 3.1: Single Byte Timing Diagram
5.2. Command Sequence Timing
A single command consists of 6 continuous single
byte serial transmissions. The following Figure 3.2
shows an example of the SYNC (AA0D00000000h)
command.

µCAM – II Serial Camera Module
Figure 3.2: SYNC Command Timing Diagram
Please refer to section 7.1 for more information
regarding synchronising the uCAM-II.
5.3. Auto-Baud Detect
The module can auto-detect the baud rate of the
incoming command. The host should make
connection with one of the following baud rates:
• 9600 bps
• 14400 bps
• 56000 bps
• 57600 bps
• 115200 bps
• 921600 bps
The module will keep using the last baud rate until
the next power cycle, or “full reset”.
Note: The baud rate can be set higher than the
baud rated determined by the Auto-Baud detect
function. Refer to Section 5.4
5.4. Setting the Baud Rates
You can set Baud rates using the Set Baud
command, refer to the table in section 6.5
Note: Baud rate changes holds until “full reset”
command is sent or Power cycle occurs. So, you can
synchronise at any of the Auto-detect Baud rate.
5.5. Sleep mode
After the camera has been idle for 15 seconds it
enters sleep (low power) mode. To wake up the
camera in this state it is necessary to send the ‘Sync’
command. If the camera is required to stay awake,
it is recommended to periodically end a ‘Sync’
command, such as every 10 seconds, to prevent the
camera going to sleep if no other commands are
being sent. If communications are occurring
between the Host and the camera, the camera will
not go to sleep until it has been idle for 15 seconds.

6.1. INITIAL (AA01h)
The host issues this command to configure the image size and Image Format. After receiving this command, the
module will send out an ACK command to the host if the configuration was successful. Otherwise, a NAK
command will be sent out.
6.1.1. Image Format
The uCAM-II can support 4 different image formats as follow:
8-bit Gray Scale (RAW, 8-bit for Y only)
03h
16-bit Colour (RAW, CrYCbY)
08h
16-bit Colour (RAW, 565(RGB))
04h

6.3. SNAPSHOT (AA05h)
The uCAM-II will hold a single frame of still picture data in its buffer after receiving this command. This snapshot
can then be retrieved from the buffer multiple times if required.
6.3.1. Snapshot Type
Compressed Picture (JPEG)
00h
Uncompressed Picture (RAW)
01h
6.3.2. Skip Frame Counter
The number of dropped frames can be defined before capture occurs. “0” keeps the current frame, “1” captures
the next frame, and so on.
6.4. SET PACKAGE SIZE (AA06h)
The host issues this command to change the size of the data package which is used to transmit the compressed
JPEG image data from the uCAM-II to the host. This command should be issued before sending SNAPSHOT or
GET PICTURE commands to the uCAM-II.
Note: The size of the last package varies for different JPEG image sizes.
6.4.1. Package Size
The default size is 64 bytes and the maximum size is 512 bytes.
ID : Package ID, starts from zero for an image
Data Size : Size of image data in the package
Verify Code : Error detection code, equals to the lower byte of sum of the whole package data except the verify
code field. The higher byte of this code is always zero. i.e. verify code = lowbyte(sum(byte[0] to byte[N-2]))
Note 1:
Once the host receives the image size from the uCAM-II, the following simple equation can be used to calculate
the number of packages that will be received according to the package size set. The package settings only apply
for compressed JPEG images.
Number of packages = Image size / (Package size – 6)
Note 2:
As the transmission of an uncompressed (RAW) image does not require the package mode, it is not necessary to
set the package size for an uncompressed image. All of the pixel data for the RAW image will be sent continuously
until completion.

7. Command Protocol
This section outlines command usage and protocol transaction between the host and the uCAM-II module.
ACK and NAK responses are typical as replies from the Camera after sending a command, however silence is
also possible if the camera has gone to sleep. Please refer to Section 6.9 and 6.10 for ACK/NAK information.
7.1. Synchronising the uCAM-II
Send the SYNC command until receiving the ACK command from uCAM-II (usually an ACK command is received
after sending the SYNC command 25 times). This must be performed following a power-up.
Note 1:
The host should send the SYNC command one by one continuously until receiving the ACK and SYNC commands
back from the uCAM-II module. Sometimes up to 25 to 60 SYNC commands maybe required before the module
will respond. After receiving the response, the host should reply with the ACK command to finalise the
synchronisation process.
Note 2:
After synchronising and establishing a communications link with the uCAM-II, allow up to 1-2 seconds before
capturing the first image. The uCAM-II needs this time to allow its AGC and AEC circuits to stabilise, otherwise
the received image luminance maybe too high or too low.
Note 3:
The SYNC command is used to wake the camera up from Sleep (see Section 5.5), and is also used to keep the
camera awake by periodically sending this command. Periodically sending commands is only required if no
commands have been sent. If communications are occurring between the Host and the Camera, the camera will
stay awake. When they stop for 15 seconds, the camera will go to sleep and will require waking with the SYNC
command.

8. Lens Information
9. Troubleshooting
Q) Cannot connect to the camera, SYNC always fails
A) Unplug the camera and plug it in again, try to SYNC again. If this fails, then the power supply you are
using may have a slow rise time. Testing of power supplies with a rise time of under 5uS resulted in
correct operation. Power supplies with a rise time of greater than about 50uS resulted in trouble to
SYNC. Change your power supply and try again.
Q) Cannot focus the camera on the target
A) Please refer to the table in section 8, and ensure you are using the correct lens for the distance to the
object. Twist the lens in or out to adjust the focus, and secure using the lock nut.
Q) Camera no longer responding to Serial Commands
A) The uCAM-II will go to sleep after 15 seconds of sitting idle. Sending the SYNC Command will wake the
camera from sleep, and will enable normal operation once again.
Q) Camera not responding to anything
A) In rare situations the uCAM-II may stop responding. Restarting the uCAM-II by powering off and on
again should restore correct operation.

11. 4D Systems - Workshop 4 IDE
Workshop 4 is comprehensive software IDE that provides an integrated software development platform for all
of the 4D family of processors and modules. The IDE combines the Editor, Compiler, Linker and Downloader to
develop complete 4DGL application code for the relevant modules, and provides tools for modules which are
not programmed.
When using the uCAM-II with Workshop 4, a test application called “4D uCAM-II Demo” will be available to test
the camera.
The following image illustrates how to connect the uCAM-II to a PC to use when testing the module with
Workshop 4, using the 4D Programming Cable.
