1 General

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.

5.4 Input and Output Circuits

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.

5.4.1 Video input

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.

5.4.2 Trigger input

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.

5.4.3 HD and VD input

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.

5.4.4 HD, VD, PCLK, WEN and EEN output

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).
