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 attrac

CV-M30 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 i

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

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

CV-M30 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

CV-M30 7.2. Internal Switch and Jumper Settings Inside the camera there are switches for 75 termination of external trigger/VD and HD and for trigger mode select. There are also jumpers for gamma select. 7.2.1. Trigger/VD and HD Termination On the PK8212 board switch SW1 for 75 Ohm termination of external trigger/VD and HD is found. SW1-1 is for external HD termination. SW1-2 is for external trigger or external VD termination. ON is 75 Ohm termination. It is factory setting. OFF

CV-M30 8. Internal Adjustments of Video Signal For adjustment of the video output signal there are internal potentiometers on th PK 7987A board. Adjustment should only be done in a setup with a standard test chart and controlled illumination Do not touch these potentiometers unless you are familiar with camera adjustments. VR 1 is for AGC level setting. Factory setting is 700 mVpp ±30 mV VR2 is for black level set-up. Factory setting is 20 mVpp ±2 mV VR3 is for white clip level.
