CV-M77
The CV-M77 camera is a compact RGB color progressive scan camera designed for automated imaging applications. The 1/3" CCD sensor with square pixels and primary mosaic filter offers a superb image quality and the build in DSP assures high color reproduction.
The camera incorporates several triggered modes and various shutter functions to capture moving objects and to control the light. All camera mode settings can be controlled via an RS-232C interface or by the switch at the rear of the camera.
The CV-M77 camera is ideal for demanding color applications such as color inspection, gauging and color printing.
The latest version of this manual can be downloaded from: www.jai.com .
The latest version of the Camera Control Tool software can be downloaded from: www.jai.com .
The standard camera composition consists of the camera main body and the operation manual.

In the following schematic diagrams the input and output circuits for video and timing signals are shown. For alternative connections refer to “Internal Switch and Jumper Settings”. Jumper settings are shown as for factory default.
The video output signal is a 75Ω RGB video signal. The signal level is 0.7Vpp. Composite sync. is selectable on the green
video signal via software or the internal switch 302-3. The sync. signal level is 0.3Vpp.

The trigger input is AC coupled with a flip-flop. The input signal level is 4V ± 2V.
The trigger input impedance is 1.2 kΩ or 75Ω selectable via the internal switch S301-3.

The HD and VD input circuit can be 75Ω terminated via the internal switch S301-1 and S301-2.
The input signal level is 4V ± 2V.
The output circuits for these signals are 75Ω complementary emitter followers. The single circuit delivers a TTL signal. The output level ≥ 4 V from 75Ω (no termination).
