5GETTING STARTED
There is no CDROM delivered with the Camera : Both User Manual (this document) and CommCam
control software have to be downloaded from the web site : This ensure you to have an up-to-
date version.
Main Camera page : www.e2v.com/cameras
On the appropriate Camera Page (EM2 or EM4) you’ll find a download link
first version of CommCam compliant is indicated in the last Chapter
CommCam download requires a login/password :
¾ Login : commcam
¾ Password : chartreuse
Setting up in the system
Vocabulary :
w = size of the sensor line (40,96mm for the 4k 10µm)
FOV = Field Of View (width of the web inspected by the sensor line) in mm.
L = Working distance (from the Lens to the Web) in mm.
f = focal distance of the lens in mm.
S = Speed of the web in mm/s
We have :
The ratio M = w/FOV is called Magnification.
The FOV is grabbed by 4096 pixels in the
width.
In order to get a ratio of 1 :1 in your image, at
the web speed of S, your line rate has to be
set :
Line Rate = (S/FOV) x 4096
Ex : if the FOV = 11 cm (110mm) and the speed
of the web is S= 0,3 m/s (300mm/s) the line
rate will be :
Line Rate = (300 /110) x 4096 = 11170 Lines/s.
If you use a 60mm lens, the working distance
will be : L = (60 x 110) / 40,96 = 161mm.
This will certainly require a macro lens.

6CAMERA SOFTWARE INTERFACE
6.1 Control and Interface
As all the e2v Cameras, the DIVIINA is delivered with the friendly interface control software
COMMCAM.UCL (as “Ultimate Camera Link”) which is based on the GenICam standard
COMMCAM recognizes and detects automatically all the UCL Cameras connected on any transport layers
(Camera Link or COM ports) of your system.
Once connected to the Camera you have an easy access to all its features. The visibility of these
features can be associated to three types of users: Beginner, Expert or Guru. Then you can make life
easy for simple users.

6.2 Serial Protocol and Command Format
The Camera Link interface provides two LVDS signal pairs for communication between the camera and
the frame grabber. This is an asynchronous serial communication based on RS-232 protocol.
The serial line configuration is:
¾ Full duplex/without handshaking
¾ 9600 bauds, 8-bit data, no parity bit, 1 stop bit.
6.2.1 Syntax
Internal camera configurations are activated by write or readout commands.
The command syntax for write operation is:
w <command_name> <command_parameters><CR>
The command syntax for readout operation is:
r <command_name><CR>
6.2.2 Command Processing
Each command received by the camera is processed:
¾ The setting is implemented (if valid)
¾ The camera returns “>”<return code><CR>
We recommend to wait for the camera return code before sending a new command.
Table 5-1. Camera Returned Code
Returned code meaning
>0 (or “>OK”) : All right, the command will be implemented
>128 Command Error (Command not recognize or doesn't exist)
>129 Error: communication failure.
>130 Error: protocol failure.
>131 Error: parameters are out of range.
>132 Error: access failure.
>133 Error: access denied.
>134 Error: initialization failure.

6.3 Camera Commands
6.3.1 Information
These values allow to identify the Camera. They can be accessed through the CommCam software in the
“Info” section
All these values are fixed in factory except the Camera User ID which can be fixed by the Customer:
•Vendor name “e2v”
ÖRead function: “r vdnm”;
Return by the camera: “e2v” (string)
ÖCan not be written
•Model Name: Camera model name
ÖRead function: “r mdnm”;
return by the camera (string) : DiviinaLM2CL
ÖCan not be written
•Camera ID : part number, serial number of the Camera
ÖRead function : “r idnb”;
Return by the camera (string 50 bytes max) :
ex : EV50YLM2CL1014-BA0-0000000000-0908P0001-AA
with :
EV50YLM2CL1014-BA0 : Part number
0000000000 : Batch number (not used for Cameras)
0908P0001 : Serial number
•“09” : Year of manufacturing
•“08” : week in the year
•“P” as Proto, “M” as Manual, “A” as automatic : type of testing

6.3.2 Setup
•Signal source : Defines if the data comes from the Sensor or the FPGA (test Pattern). This
command is available in the CommCam “Setup” section :
ÖRead function : “r srce”;
Return by the camera: “0” if Source from the Sensor and “1” if test pattern active
ÖWrite function : “w srce” <value> :
“0” to switch to CCD sensor image
“1” to switch to Test Pattern.
The Test pattern is a single ramp. The test pattern is generated in the FPGA : It’s used to point out
any interface problem with the Frame Grabber.
The test pattern is a 8bit width pattern composed with several ramps from 0 to 255 all along the
whole Camera definition. Then the number of ramps depends on the number of pixels of the Camera
Test patterns are detailed in Appendix A.
•Auto Tap Balance : Enables the Auto Tap balance. This command is available in the CommCam
“Setup” section :
ÖRead function : “r abal”;
Return by the camera: “0” if Tap balance disabled and “1” if enabled
ÖWrite function : “w abal” <value> :
“0” : Disable the auto Tap Balance
“1” : Enable the Tap balance.
How works the Automatic Tap Balance ?
The Auto Tap Balance is a Laplace filter which is applied in the FPGA. It automatically solve any
odd/even mismatch that can be visible in the image
¾Whatever the action you may have on the Odd/even Tap Gains to increase the mismatch
between the Taps, the filter will correct if enabled
¾The filter has to be disabled if the inspection is done at Nyquist frequency : Then the tap
balance has to be performed by using odd and even Tap Gains.
The Camera is delivered with the Auto Tap Balance enabled by default.

6.3.3 Exposure and Synchronization
•Synchronisation Mode:Timed or Triggered, it defines how the grabbing is synchronized.This
command is available in the CommCam “Exposure” section :
ÖRead function : “r sync”;
Return by the camera:
•0 : Free Run or “Timed” mode
•1 : Ext Trig with Integration time set in the Camera
•2 : Ext ITC (Integration Time Controlled) : The same Trig signal defines the line period and
its low level defines the integration time
•3: Ext Trig with two trig signal : CC2 defines the start of the integration and CC1 defines
the Stop of the integration.
ÖWrite function : “w sync” <value>
Timing Specifications
This table is for all the synchronization modes.

Exposure Mode Timed : Free Run
This mode doesn’t require an external trigger.
In this case, the line period (Lp) can be defined in the Camera (see below) but the real line period of the
camera depends also on the exposure time (tint) set:
¾If tint > tper, the line period is equal to tint
¾If tper > tint, the line period is equal to tint
Ext Trig with integration time set in the camera
This mode requires an external trigger ( via CC1) but the exposure time is the one defined in the Camera.

Ext Trig with Integration Time Controlled (ITC) with one Trig
This mode requires an external trigger ( via CC1). Both exposure time and line period are defined by this
Trig signal :
¾The exposure time during the low level of the Trig Signal
¾The line period between two rising edges of the Trig Signal
Ext Trig with Integration Time Controlled (ITC) with two Trigs
This mode requires two external triggers ( via CC1 and CC2):
¾CC2 controls the starting of the exposure time
¾CC1 controls the end of the exposure time.
The line period is defined by the one of the CC2 Trig signal.
If the line period of the Trig signal provided to the camera is bigger than the exposure
time set in the camera, the “short trig pulses” will be ignored : The exposure set in the
camera defines the minimum line period possible.

•Exposure time:Defines the integration time when set in the Camera.This command is available in
the CommCam “Exposure” section :
ÖRead function : “r tint”;
Return by the camera : Integer from 4 to 65534µs (by step of 1µs)
ÖWrite function : “w tint” <value> ;
This value of integration time is taken in account only when the synchronisation mode is “free run” (0)
or “Ext Trig with Integration time set” (1). Otherwise it’s ignored.
•Line Period:Defines the Line Period of the Camera in Timed mode.This command is available in the
CommCam “Exposure” section :
ÖRead function : “r tper”;
Return by the camera : Integer from
Tpermin to 65535 (by step of 1µs)
Tpermin depends on the number of pixels on the sensor :
28µs for the 1K Pixels cameras (35,714kHz)
55µs for the 2K pixels cameras (18,182kHz)
105µs for the 4k pixels cameras (9,523 kHz)
ÖWrite function : “w tper” <value> ;
The Tper min value is not displayed in CommCam for each camera but any attempt to set to a lower
value then this will be refused by the camera.
In the same way, it’s impossible to set the line period at a lower value than the exposure time.
Note that if the exposure time is increased and set at a lower value than the line period, this last one
will be automatically adjusted at the value of the exposure time : This modification won’t appear in
CommCam without disconnect/reconnect

6.3.4 Gain and Offset
•Analog Global Gain:Set the Amplification Gain.This command is available in the CommCam “Gain &
Offset” section :
The Value set is also copied in the both odd and even Gains.
ÖRead function : “r gain”;
Return by the camera: Value from 0 to 880 corresponding to a Gain range of 0 to 31dB by step of
0,0351dB
ÖWrite function : “w gain” <int> ;
•Analog odd/even Gains per Tap:A separate command for each sensor is also available for each
sensor Tap.These commands are available in the CommCam “Gain & Offset” section :
Gains Management and Auto Tap Balance
The Global Gain is a “virtual” global command which affects both Odd and Even Gains in the same time.
Each value set in the Global Gain erases Odd and Even Gain values.
This gain has to be used when the Auto Tap balance is activated as a “friendly” mode to set quickly the
gain level in the Camera without taking care of the Tap balance which is automatically done by the
Laplace filter.
¾The Value set for the Global Gain is copied in both Odd and Even Gains
¾The value set for the Odd Gain is copied in the Global Gain value
¾Whatever the action you may have on the Odd/even Tap Gains to increase the mismatch
between the Taps, the filter will correct if enabled. But an individual action on the Odd Gain
will increase the global gain in the same way.
¾In CommCam the odd/gains Values are not refreshed after the setting of the Global gain
command : You have to refresh them individually with a right click on the value.
