CV-M40
1. General
The CV-M40 is a 1/2” CCD progressive scan camera, incorporating double speed and partial
scan techniques, housed in a compact and robust package.

60 full progressive frames per second over a single video output
120 frames per second using vertical binning (half vertical resolution, pixel aspect ratio 1:2)
Internal, external, HD/VD or random synchronization
3 external trigger/readout modes : Edge pre-select, pulse width and frame-delay readout
Shutter speed 1/125 to 1/12,000
24.5 MHz pixel frequency and 31.468 kHz line frequency
Video output with or without sync.
Set-up by RS 232C or switches
Up to 233 frames per second with partial scan (user selectable)

To output int. HD/VD signal, make jumper JP9/JP11 open-circuited, and JP12/JP13 short-
circuited. All jumpers are located on PK8273 board. Please refer to 7-2-3. Jumpers on
PK8273 board.
b) Output of internal HD/VD signal
Int. HD/VD signal is effective only at 75 Ohm termination.

6-2-1.Edge pre-select mode
In this mode, the exposure starts at the falling edge of the external trigger pulse. The WEN
pulse originates from the camera.
The shutter speed is controlled by the SW1 switch on the rear panel of the camera and the RS
232C serial interface.
For details, refer to the timing charts section of this manual.
To use this mode, set up the camera as follows ;

6-2-2. Pulse width control mode
In this mode, the exposure time is controlled by the pulse width of external trigger pulse. The
exposure starts at the falling edge of the external trigger pulse and ends at the rising edge of
the external trigger pulse. The WEN pulse is generated and output from the camera.
For details, refer to the timing charts section of this manual.
To use this mode, set up the camera as follows ;
Set SW1-5 at OFF, and SW1-6 at ON to select the Pulse width control mode.

Jumpers JP1 and JP2 are used to select the gamma setting. See table below for options.
Please note that both jumpers must be in the “open” position to allow RS 232C setting of
gamma. If no setting is provided via RS 232C, the camera will default to gamma 1.0.
Do not set the jumpers both JP1/JP2 at short circuited, as it causes a serious damge to the camera.
