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 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.

CV-M77 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.
CV-M77 6 Functions and Operation Apart from the standard continuous operation, the CV-M77 features three external triggering modes, Edge Pre-select, Pulse Width Control mode and Readout Delay mode. These 3 external triggering modes operate with H non-reset. In H non-reset, the exposure will be synchronized to the internal HD and the exposure will start at the first HD after the negative going edge of the trigger (see figure 6-1). EDGE PRE-SELECT H non-reset Trigger int.
CV-M77 time (accumulation time) is governed by the fixed shutter speed set up by the rear panel DIPswitches or via RS-232C control. The resulting video signal will start to be read out after the selected shutter time. The WEN pulse indicates the start of valid video signal. Refer to timing charts for details. A new trigger pulse must not be applied before the video read out has finished. If the camera is synchronized to an external HD signal, there are some requirements to the phase between the ext.
CV-M77 Set SW1-5 and SW1-6 on the rear plate of the camera to “ON” and SW1-7 to OFF or use the RS 232C control to set-up the PWC mode of the camera. 6.3.3 Frame-delay Readout Mode 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. The exposure ends at the rising edge of the external trigger signal. The trigger pulse must be longer than >1H.

CV-M77 7 Configuring the camera using the serial interface. 7.1 Mode Setting using ASCII commands via the RS-232C port. The configuration of the CV-M77 camera can be done via the RS-232C port. The camera is to be set up via an ASCII terminal or from a PC running terminal emulator software. Below is the description of the ASCII based short command protocol. The RS-232C serial interface specification for CV-M77 is: 7.2 Communication setting Baud Rate Data Length Stop Bit Parity Xon/Xoff Control 7.

CV-M77 8 Switch Settings Before changing any switch settings or jumper settings turn off the power. 8.1 Mode Settings by 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 RS-232C control is disabled.
CV-M77 The SW301 switches (1-3) in “ON” position activates 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. 8.2.2 SW302 switch S302 OFF ON White - 1 xxxx Balance 2 xxxx Sync. on G: 3 xxxx WEN: 4 xxxx The SW302 switch has the following functions: The switches (1-2) determines the color temperature, the switch (3) activates Composite sync.
CV-M77 9 Jumper settings Before changing any switch settings or jumper settings turn off the power. 9.1 Jumper locations The jumpers are located on two boards, the PK8309A board and the PK8308A board: JP402 JP401 1SS302 D1FS4 02CZ7.

CV-M77 10 CV-M77 Camera Control Tool The Camera Control Tool software for the CV-M77 camera is available from the JAI homepage (www.jai.com). The software runs under Windows 98, NT and Windows 2000. The software interface has incorporated all the commands described in the ASCII protocol in an easy to use fashion – more user-friendly for some than the HyperTerminal or similar programs. From www.jai.com Camera Control Tool software for windows 98/NT/2000 can be downloaded.
