CV-M77 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 built-in DSP assures high color reproduction.
CV-M77 4. Locations and Functions Lens mount of C-mount type. *1) 1/3" CCD sensor with primary color mosaic filter. (Bayer filter). R Gain Potentiometer. To adjust Red gain level manually. B Gain Potentiometer. To adjust Blue gain level manually. MG Gain Potentiometer. To adjust Master gain level manually.
CV-M77 5. Pin Assignment 5.1. 12-pin Multi-connector (DC-IN/Trigger) Type: HR10A-10R-12PB-01 (Hirose) male. Pin no. Signal Remarks (Seen from rear of camera.) +12 V DC input Iris video output Video for lens iris control. (With comp sync.) Can only be used in normal continuous mode.
CV-M77 5.3. 9 pin D-sub connector (RGB/SYNC) Pin No. Signal Remarks NC/VD in VD input: JP303 “open” and JP304 “short” R output G output /Sync on G Sync. on G: SW302-3 “ON” or SY=1 B output HD input HDinput: SW303-1 “ON”.
CV-M77 5.4. Input output Circuits In the following schematic diagrams the input and output circuits for video and timing signals are shown. For alternative connections refer to “7. Configuring the Camera”. Jumper settings are shown as for factory default. RGB video output The video output signal is a RGB video signal.
6.1.1. High frame rate. From revision C, the CV-M77 camera has a new readout mode. It is the high frame rate mode. Here only every third line is read out. The 2 lines between are dumped. In this way the Bayer RGB mosaic pattern is unchanged.
CV-M77 6.2. Input/Output of HD/VD Signal 6.2.1. Input of External HD/VD signals This setting is factory pre-set. The video output is synchronized with external HD/VD signals if applied. If no ext. HD signal is input, the camera will switch to the internal X-tal controlled HD sync.
CV-M77 6.3. Continuous operation This mode is used for applications that do not require asynchronous external trigger, but run in continuous operation. Mode setting and all other settings can be done via RS 232C control if rear switch SW1-10 is ON.
CV-M77 6.4. Trigger modes The CV-M77 camera features 4 external triggering modes: 1 Edge Pre-Select. (EPS). Asynchronous reset and exposure start by an ext. trigger pulse. 2 Pulse Width Control. (PWC). Exposure control by the low period of the ext. trigger pulse.
CV-M77 6.4.1. Edge Pre-select Trigger This trigger mode operates in H non-reset mode. In H non-reset mode the exposure will start at the first internal HD after the trigger. The trigger input should be longer than or equal to 2 HD (102 µsec.).
CV-M77 6.4.2. Pulse Width Control Trigger This trigger mode where the length of the trigger pulse determines the exposure time operates in H non-reset mode. In H non-reset mode the trigger pulse and the HD signal are synchronized. The exposure will start at the first HD pulse after the falling edge of the external trigger signal.
CV-M77 6.4.3. Frame Delay Readout EPS This trigger mode operates in H non-reset mode. In H non-reset mode the exposure will start at the first internal HD after the trigger. The trigger input should be longer than or equal to 2 HD (102 µsec.).
CV-M77 6.4.4. Frame Delay Readout PWC This trigger mode operates in H non-reset mode. In H non-reset mode the trigger and HD is synchronized. The exposure will start at the first HD pulse after the falling edge of the external trigger signal.
CV-M77 6.4.5. Long Time Exposure The exposure time is the interval between 2 ext. VD pulses sent to the VD input of the camera. The exposure starts after input of the first ext. VD pulse, and ends after the next input of the ext.
CV-M77 6.5. Other functions Mode setting and all other settings can be done via RS 232C control if rear switch SW1-10 is ON. Mode setting and some other settings can be done by switch if rear switch SW1-10 is OFF.
CV-M77 Blue Gain. BG. This parameter adjust the manual color balance with the blue video level if WB=0. White balance. WB. This function selects the color balance. Manual, Auto or 2 fixed values. (Also by switch.) Auto white balance. AW.
CV-M77 7. Configuring the Camera Before changing any switch settings or jumper settings turn off the power. 7.1. Setting by Switch and Jumper 7.1.1 Rear Switch The factory setting for the SW-1 switch on the rear panel of the camera is OFF: The electronic shutter is OFF, the external trigger modes are OFF, gamma is OFF (=1.0), the AGC is OFF and the...

CV-M77 SW301 S301 The SW301 switches (1-3) in “ON” position activates ↔ 75Ω 75Ω termination of ext. HD and ext. VD signals and it activates 75Ω termination of an ext. trigger signal. The factory setting is “OFF” enabling TTL signal termination for all three signals.
CV-M77 7.1.3. Jumper settings Before changing any switch settings or jumper settings turn off the power. Jumper locations. The jumpers are located on two boards, the PK8309A board and the PK8308A board: The PK8309A board have two jumpers of interest: JP401 and JP402.
CV-M77 7.2. RS-232C control All configuration of the CV-M77 camera can be done via the RS-232C port on the 6 pin HR connector if the rear switch SW1-10 is ON (RS-232C). The camera can be set up from a PC running terminal emulator software, or using JAI´s camera control software.

CV-M77 8. Camera Control Tool for CV-M77 The Camera Control Tool for Windows 98/NT/2000 can be downloaded from www.jai.com. The control tool contents a camera control program and tools for making your own program. For the integrator and experienced user, the Camera Control Tool is much more than a program with a window interface.
CV-M77 8.2. Camera Control Tool Interface The Camera Control Tool Software is based on a main Tool Bar and a number of associated Tool Windows. Each button in the Tool Bar pops up a separate Tool Window when pressed. The layout of the program can be adjusted by arranging the windows the way it is preferred.
