CV-M30  
1. General  
The CV-M30 camera revision D is an updated version with a new CCD sensor ICX-418ALL-6 with  
improved specifications. The revision D camera can only operate in double speed.  
CV-M30 is a monochrome CCD video camera designed for industrial video sensing applications.  
The camera operates with double speed scanning, where the horizontal and vertical frequencies  
is doubled compared to a standard camera. The image-capturing speed is the double.  
The CV-M30 also offers an attractive partial scanning mode for higher frame rates. The partial  
scanning is with full horizontal scanning and 50% or 33% in the vertical direction.  
The camera is also equipped with a pulse width control mode, where the accumulation time is  
controlled by the low period of the external trigger pulse.

6. Functions and Operations  
6.1. Input of External HD/VD Signals  
As factory setting the camera can be synchronized by external HD/VD signals. The external  
supplied HD/VD signal should follow the same standard as the camera setting for speed, scanning  
and interlace. The signal level must be 4.0 Vp-p ±2.0V with 75 Ohm termination on. The  
termination can be switched off with the internal switch SW1 on the PK8212 board.  
The VD input terminal is used for external trigger signal input in the random trigger modes.  
If no external HD is connected, the camera will switch to the internal HD.  
If no external VD is connected, the camera will continue with its internal VD.  
For settings, see “7. Mode Setting.”  
6.2. Continuous Operation  
For applications that not require asynchronous trigger, but run in continuous mode, this mode is  
used. SW1-7 Trigger is set to Normal (OFF). The camera can operate in normal or double speed.  
It is set by with Sw1-5 or at pin 1 on 6 pin connector. The exposure time is selected with SW1-1  
to SW1-3. The read out can be 2:1 interlaced, non-interlaced or partial scan. It can be set by  
SW1-4 and SW1-6. Partial scanning can only operate in non-interlaced mode. Maximum field rate  
with partial scan and double speed is 360 fields per second.  
To use this mode  
Set:  
SW1-7 to OFF for normal shutter  
SW1-4 to and SW1-6 to interlaced, non interlaced.1/2 partial or 1/3 partial  
SW1-1, SW1-2 and SW1-3 to shutter speed.  
Input:  
If external synchronizing is used, input HD and VD.  
Ext. VD to pin 5 on 6 pin connector or pin 7 on 12 pin connector..  
Ext. HD to pin 6 on12-pin connector.  
75 Ohm termination is done with SW1-1 (HD) and SW1-2 (VD) on PK8212 board.  
Refer to “6.5.Timing Chart”  
For settings, see “7. Mode Setting.”  
6.3. External Trigger Mode  
This camera has two external trigger modes.  
1. Edge Pre-select Mode. (Asynchronous reset and exposure start by an external trigger.)  
2. Pulse Width Control Mode. (Asynchronous reset and exposure controlled by the low  
period of the external trigger.)

CV-M30  
6.3.1. Edge Pre-select Mode  
The edge pre-select mode will work in non-interlaced and field accumulation mode with partial  
scanning and double speed. The CV-M30 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 accumulated signal will be  
read out as a single field 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. For partial scanning the longest shutter time are not available.  
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 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.  
To use this mode  
Set:  
SW1-7 to ON for ext. trigger shutter  
SW1-4 to OFF and SW1-6 to ON for non interlaced mode  
SW2-1 on PK8212 board ton OFF for Edge Pre select mode  
SW1-1, SW1-2 and SW1-3 to shutter speed  
Ext. trigger to pin 5 on 6 pin connector or pin 7 on 12 pin connector.  
Ext. HD to pin 6 on12-pin connector. (If used).  
Input:  
75 Ohm termination is done with SW1-1 (HD) and SW1-2 (Trig) on PK8212 board.  
Refer to “6.5.Timing Chart”.  
Detailed switch 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 in non-interlaced, field accumulation mode. Double speed  
and partial scan can be used.  
2. The exposure start may delayed 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.  
Fig. 7. External trigger and HD relations  
3. The ext. trigger input is 75 Ohm terminated as factory setting. The voltage level of the ext.  
trigger has to be 4.0 Vp-p ± 2.0 V. The duration should be more than 1 H negative going. >32  
µsec. and < 1000H. The input is AC coupled.  
4. If the ext. HD input and ext. trigger input are from a TTL source, set SW1-1 (HD) to OFF and  
SW1-2 (ext. trigger) to OFF for non-terminated.

CV-M30  
6.3.2. Pulse Width Control Mode  
The pulse width control mode will only work in non-interlaced field accumulation mode.  
The exposure is controlled by the low period of the ext. trigger pulse. The CV-M30 starts the  
exposure at the first HD pulse after the falling edge of the ext. trigger pulse. The exposure ends  
at the first HD pulse after the rising edge of the ext. trigger. The Shutter can be controlled to be  
within the range from >1H (>32 usec.) to <1000H. The AC coupling causes the upper limit.  
The accumulated signal will be read out as a single field before a new trigger can be applied.  
The interval between trigger pulses must be longer than the time for 1 field + the trigger low  
time. It is the limit for the field rate.  
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 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.  
To use this mode  
Set:  
SW1-7 to ON for ext. trigger mode.  
SW1-4 to OFF and SW1-6 to ON for non interlaced mode.  
SW2-1 on PK8212 board ton ON for Pulse Width Control mode.  
Ext. trigger to pin 5 on 6 pin connector or pin 7 on 12 pin connector.  
Ext. HD to pin 6 on12-pin connector. (If used).  
Input:  
75 Ohm termination is done with SW1-1 (HD) and SW1-2 (Trig) on PK8212 board.  
Refer to “6.5.Timing Chart”.  
Detailed switch setting is described in “7. Mode Setting”.  
For connections see “5. Pin Assignment”.  
Cautions in the Pulse Width Control Mode.  
1. Pulse width control mode is effective in non-interlaced, field accumulation mode. Double  
speed and partial scan can be used.  
2. The exposure start may delayed 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.  
Fig. 8. External trigger and HD relations  
3. The ext. trigger input is 75 Ohm terminated as factory setting. The voltage level of the ext.  
trigger has to be 4.0 Vp-p ± 2.0 V. The pulse width should be >1H (>32 usec.) to <1000H.  
3. If the ext. HD input and ext. trigger input are from a TTL source, set SW1-1 (HD) to OFF and  
SW1-2 (ext. trigger) to OFF for non-terminated.

6.4. Other Functions  
6.4.1. Double Speed Mode  
The CV-M30 camera revision D operates only with double speed scanning.  
Double speed is 120 fields per second. (V= 119.88Hz. H=31.468 kHz).  
To use this mode.  
Set:  
6.4.2. Partial Scanning Mode  
To obtain a higher frame rate, the partial scanning can be used. In this mode only the vertical  
center part of the CCD sensor is read out. Partial scan will only work in non-interlaced mode.  
The useable image format is  
Full non-interlaced  
1/2 partial  
1/3 partial  
752(h) x 242(v) pixels (120 fields/second in continuous).  
752(h) x 111(v) pixels (240 fields/second in continuous).  
752(h) x 67(v) pixels (360 fields/second in continuous).  
With external trigger and partial scan the maximum field rate is less then the above shown. The  
maximum field rate is given of the actual shutter time plus the readout time.  
To use this mode.  
Set:  
SW1-4 and SW1-6 on the rear panel as follows:  
Full SW1-4 OFF, SW1-6 OFF  
1/2 partial SW1-4 ON, SW1-6 OFF  
1/3 partial SW1-4 ON, SW1-6 ON  
Note:  
In this mode, the shutter speed has limitation depending on the selected range.

11.2. Typical CCD Characteristics  
The following effects may be observed on the video monitor screen. They do not indicate any

When the CCD camera captures stripes, straight lines or similar sharp patterns, jagged image on  
the monitor may appear.
