CV-M300
1. General
The CV-M300 is a monochrome 2/3" CCD camera designed for automated imaging applications
featuring high performance and unique functions within a uniform and compact housing.
The high-speed shutter function and asynchronous random trigger function allow the camera to capture
high quality images of fast moving objects. It is suitable for industrial applications such as on-line
inspection and measurements.
In addition to conventional random trigger modes, the newly added pulse width control shutter mode
makes it possible control the accumulation time by the trigger pulse width.

The standard camera composition consists of the camera main body, tripod mount plate and operation
manual.

6. Functions and Operations
6.1. Input/Output of HD/VD Signal
6.1.1. Input of External HD/VD Signal
As factory setting the camera can be synchronized by external HD/VD signals. The signal level must be
4.0 Vp-p ± 2.0V at the input with the 75 Ohm termination ON. To change to non-terminated input, see
instructions in “7. Mode Setting”.
If no ext. HD is connected, the camera will switch to the internal X-tal controlled HD.
If no ext. VD is connected, the camera will continue with its internal VD.
6.1.2. Output of Internal HD/VD Signal
The internal HD/VD output is 4.0 Vp-p from a 75 Ohm source.
To select this mode, see instructions in “7. Mode Setting”.
6.2. Normal Shutter Mode
When trigger select SW1-4 is OFF, the camera is in normal mode. The SW1-1, SW1-2 and SW1-3 are for
selecting the shutter speed. The range is from OFF to 1/10,000 second in 8 steps. The camera is running
continuously with an exposure as the selected shutter time.
The shutter time setting is shown in “7.1.3. Table for Shutter Time”.
6.3. External Trigger Mode
External trigger mode of CV-M300 allows 4 different driving modes, as follow.
1 Edge pre-select mode. (Asynchronous reset and exposure start by an ext. trigger)
2 Pulse width control mode. (Exposure control by the low period of the ext. trigger)
3 Start/Stop trigger mode. (Exposure start by the ext. trigger and end by the ext. VD signal)
4 Long time exposure mode. (Exposure control by the interval of the ext. VD signal)
The trigger input is AC coupled, so there is a maximum pulse width for the trigger pulse of around 60
msec. The signal level must be 4.0 Vp-p ± 2.0V. The trigger input has a fixed resistance larger than
1 kOhm and cannot be terminated with 75 Ohm by internal settings.
The following describes the details of each trigger mode.
6.3.1. Edge Pre-select Mode
The edge pre-select mode operation will only work in non-interlaced and field accumulation mode. The
CV-M300 starts the exposure (= accumulation of photoelectric charge) at the first HD pulse after the
falling edge of the ext. trigger pulse. The exposure ends after the time set by the 3 shutter switches
SW1-1 to SW1-3. The range is 8 steps from OFF (1/60 or 1/50) to 1/10,000 second.
In this mode, the EEN (Exposure ENable) pulse and WEN (Write ENable) pulses are generated and
output from the camera. The EEN pulse indicates the exposure time and can be used to control the
illumination such as strobe light. The EEN pulse is output from pin 2 of the 6-pin multi connector. The
signal level is 4.0 Vp-p from a 75 Ohm source.
The WEN pulse indicates the time period of the effective video signal output, and is useful for the timing
and interfacing of external devices such as frame grabbers. The WEN pulse is output from pin 6 of the 6pin multi connector. The signal level is 4.0 Vp-p from a 75 Ohm source.
The video must be read out before a new trigger can be applied. The interval between trigger pulses
must be longer than the time for 1 field + the shutter time. It is the limit for the field rate.

CV-M300
To use this mode
Set: SW1-4 to ON for ext. trigger shutter
SW1-5 to OFF for field accumulation
SW1-6 to ON for non-interlaced
SW1-1, 2 and 3 to shutter speed
Input: Ext. trigger to pin 5 on 6 pin multi connector.
Ext. HD to pin 6 on 12-pin multi connector. (If used).
75 Ohm termination is done with SW2-1 (HD) on PK8041 board.
Refer to Timing Chart and Cautions on next page.
Detailed switch and jumper setting is described in “7. Mode Setting”.
For connections see “5. Pin Assignment”.
Cautions in the Edge Pre-select Mode.
1. Edge pre-select mode is effective only in non-interlaced, field accumulation mode.
2. The exposure start may delay up to 1H max., when the falling edge of ext. trigger pulse is not
synchronized with the falling edge of ext. HD signal. To avoid this 1H delay and jitter, the falling edge
of the trigger pulse should be synchronized with the HD pulse as shown below. It can be the ext. HD
input or the Internal HD output.

Ext.HD
AA AA
A=4.4µS
3. The ext. trigger input is TTL level. The duration should be more than 1 H negative going. >64 µsec.
and < 60 msec. The input is AC coupled.
4. If the ext. HD input is TTL level, set SW2-1 OFF for non-terminated. See “7.2 SW2 on PK8041 Board”.
