1. General
The CV-M91 3 CCD RGB color camera is a new updated version of CV-M90. The prism is improved,
and new CCD sensors are used. The new CCD sensor has 5 dB higher sensitivity, 15 dB lower
smear and 4 dB higher dynamic range. Now there are Y/C output and input for composite sync.
Pulse width control shutter is now fully implemented.
CV-M91 is a 3 CCD RGB color camera designed for machine vision and image processing
applications where excellent resolution, high quality color reproduction are required.
The compact 3 CCD C-mount optical prism unit is designed for high color quality, and it allows
use of a wide range of C-mount lenses.
CV-M91P is the CCIR PAL version, and CV-M91N is the EIA NTSC version.

EEN (Exposure Enable) pulse indicates the duration of the shutter, and can be used for
controlling strobe illumination.
EEN will be low all the time in normal continous mode if the shutter is off.
WEN (Write Enable) pulse indicates the period of effective video signal output. It is
usefull for setting the timing with framegrabber.

5.4. Input and Output Circuits
In the following schematic diagrams the input and output circuits for video and timing signals
are shown.
Video outputs
The video output is a 75 Ω DC coupled circuit.
The video DC level for video and video + sync
are shown with 75 Ω termination.

5.5. Prism unit
For best color performance, the lens
should be designed for 1/3” 3CCD camera.
Otherwise color shading can be a problem.

6. Functions and Operations
The different camera modes and functions can be set by switches and jumpers. Some functions
like RGB setup and white clip can only be changed via RS-232C.
Function names within “ “ are names used in camera control tool.
6.1. Input/Output of Signals
6.1.1. Input/output of HD/VD
In the default setting the camera will accept external HD/VD signals on pin 6 and 7 of the 12 pin
Hirose connector. If external HD/VD is applied, the camera will synchronize to it. If no external
sync signals are applied, the camera will operate with its internal x-tal controlled sync.
The time requirements to the relation between VD and HD are shown in fig. 10.
The input is TTL level as factory setting. It can be 75 Ohm terminated by an internal switch.
Internal HD/VD signals can be output on pin 6 and 7 by internal jumper settings. The output is
TTL level from a 75-Ohm source. In trigger modes a VD pulse will only be output after an
external trigger pulse.
Refer to “7. Configuring the Camera.”
To use this mode:
Set function on PK8407: JP305 s, JP306 o for ext. VD input. Factory default.
JP308 s, JP309 o for ext. HD input. Factory default.
SW301-1(HD), SW301-2(VD) to OFF for TTL level. Factory default.
SW301-1(HD), SW301-2(VD) to ON for 75 Ω termination
JP305 o, JP306 s for int. VD output
JP308 o, JP309 s for int. HD output
Input/output: Ext. VD in or int. VD out on pin 7 on 12-pin connector.
Ext. HD in or int. HD out on pin 6 on 12-pin connector.
If only a composite VS signal is available, it is possible to enable an internal sync separator to
separate HD and VD from the composite signal.
To use this mode:
Set jumper on PK8407: JP312 s, JP313 o, JP315 o, JP318 s, JP319 o for HD/VD input. Default.
JP312 o, JP313 s, JP315 s, JP318 o JP319 s for comp. VS input.
Input Ext. VS (1Vpp ±30%) on pin 7 on 12 pin connector.
Important notes on using this mode.
• External sync system should follow the camera scanning system
• Requirements to HD/VD phase is shown in fig. 10
Fig. 10. Ext. HD and VD phase conditions.

6.1.2. Internal sync out/WEN out
On pin #7 on 9 pin sub-D connector, the factory setting is the internal composite sync signal out.
By jumper settings it can be changed to WEN out.
Refer to “7. Configuring the Camera.”
To use this mode:
Set function on PK8407: JP303 o, JP304 s for sync output. Factory default.
JP303 s, JP304 o for WEN output.
6.1.3. Internal pixel clock out
The internal pixel clock can be output on pin #9 on the 12 pin connector. As factory setting it is
not connected.
Refer to “7. Configuring the Camera.”
To use this mode:
Set function on PK8407: JP310 o, for no pixel clock out. Factory default.
JP310 s, for pixel clock out.
Important notes on using this mode.
• If not used, the pixel clock should not be output.
6.1.4. VBS out on pin#4 12 pin.
On pin #4 on the 12 pin connector, the video signal can be output as a composite signal.
Refer to “7. Configuring the Camera.”
To use this mode:
Set function on PK8404: SW604-1 on for VBS video signal out on pin #4 12 pin. Factory default.
SW604-1 off for no signal out on pin #4 12 pin.
6.1.5. Y out/VBS out on pin#6 9 pin sub-D.
The signal output on pin #6 on the 9 pin sub.D connector can be changed from Y output to
composite video output.
Refer to “7. Configuring the Camera.”
To use this mode:
Set function on PK8404: SW604-2 off, SW604-3 on for Y out on pin #6 9 pin. Factory default.
SW604-2 on, SW604-3 off for VBS out on pin #6 9 pin.
6.1.6. Green out/sync on green on pin#4 9 pin sub-D.
The green signal output on pin #4 9 pin sub-D can be changed to be composite sync on green.
Refer to “7. Configuring the Camera.”
To use this mode:
Set function on PK8404: SW604-4 off for green video out on pin #4 9 pin. Factory default.
SW604-4 on for sync on green out on pin #4 9 pin.
