CV-M71A 1 General The CV-M71A is an analog output RGB color camera, based on a progressive scan primary mosaic Bayer CCD sensor. It provides 60 full frames/second through a 9-pin D-sub connector. There is also a Camera Link version of this camera, called the CV-M71CL.

6 Functions and Operations Basic functions The CV-M71A camera is a progressive scan camera with a primary color mosaic CCD (Bayer). An internal DSP performs the color-interpolation, outputting separate analog R, G and B signals through the 9-pin D-sub connector.

CV-M71A 6.3.1 (a) External Synchronization ( VD timing Details ) timing Details FIGURE 16.VD Note: The internal VD is reset by the falling edge of Ext. VD but there is no field identification. The pulse width of Ext. VD requires 9H to 12 H.
CV-M71A 6.3.1 (c) External Synchronization ( HD timing details ) FIGURE 18.HD timing details Note: The pulse width of Ext. HD requires between 48clk to 166clk. HD can not be reset directly. 6.3.2 Input of external trigger The external trigger signal can be by means of pin 5 on the 6-pin connector (TI=0) or pin 11 on the 12-pin connector.
CV-M71A To avoid <1H time jitter in HD synchronous mode, it is recommended the trigger be synchronized to the HD as shown in Figure 19. If trigger transitions are inside the limits shaded blue, the accumulation jitter is minimal. FIGURE 19.Trigger to ext. HD phase relation In the following chapters the different operation modes and functions are covered.
CV-M71A 6.4.2 HD asynchronous accumulation With LS=1, the accumulation starts after the trigger leading edge. • • The exposure start delay is fixed. See the table included in Figure 22 for the fixed delay. • In EPS mode the exposure stops 0.5 H after the selected shutter time, (in number of HD).

Full frame. 6.4.3 Continuous operation This mode is used for continuously running applications not requiring an asynchronous external trigger. For timing details, refer to fig. 14. through fig. 17.

CV-M71A selected shutter time. To avoid up to 1LVAL time jitter in HD synchronous accumulation, it is recommended to synchronize the trigger to HD (see Figure 19 on page 14). Use HD synchronous accumulation (LS=0) for the highest trigger rate. A new exposure can be started while the previous is read out.

CV-M71A To inhibit the internal XSG pulse and continue the accumulation, the external sensor gate control signal should be low during line 28, where the internal XSG is placed. Refer to Figure 27 on page 21. The sensor gate control signal can be synchronized by the VD signal.
The default trigger polarity is active low (falling edge) (TP=0). It can be inverted to active high (TP=1). Gamma. GS=0, GS=1 For CV-M71A, gamma is selectable between 0.45 (GS=1) and 1.0 (GS=0). Factory default is 1.0. Gain settings. AS=0, AS=1.

CV-M71A 7 Configuring the Camera Switch setting by internal SW301, SW302 and SW303. • SW301 is used for 75 ohm termination for trigger and HD/VD input. SW302 is used for communication port select , D-sub 9-pin or Hirose 12-pin , as for HD input.
All configuration of the CV-M71 A camera is done by means of the RS-232C port on the 6-pin Hirose connector. The camera can be set up from a PC running terminal emulator software, or using JAI’s camera control software. Below is the description of the ASCII based short command protocol.
