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.

5. 6-Pin connector for Input/output of control signals
6. 12-Pin connector for 12V DC power and external sync signals
7. Gain potentiometer for manual gain adjustment
8. Screw holes for Tripod mount plate. (Screws 3.0 x 5mm)
9. Tripod mount plate to place the camera on a tripod
Note *1): Rear protrusion on the C-mount lens must be less than 10mm (0.4 inches approx.).
When IR-cut filter is used, it must be less than 7.0 mm (0.28 inches approx.).
The IR-cut filter is placed in the C-mount thread.
The C-mount IR-cut filter must be ordered separately.

Avoid double termination
*2) If external trigger pulse is input on either No.7 of 12 pin connector or
No. 5 of 6 pin connector, no external VD signal should be input on the
other.

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.)

Fig. 6. External trigger modes
The trigger input is AC coupled, and the exposure will start at the first HD pulse after the trigger
falling edge. The trigger pulse width should be > 1H to < 1000H.
