CV-A50 IR 1. General The CV-A50 IR is a monochrome CCIR and EIA interlaced 1/2” CCD cameras with enhanced near IR response, designed for a wide range of automated imaging application. The camera features a compact housing and a wide range of unique functions.
CV-A50 IR 4. Camera Housing and Dimensions Fig. 1. Locations and dimensions. 12-pin Hirose connector for frame grabber interfacing and power (12V DC). BNC connector for video output. VS 1.0 Vpp 75 Ohm. 6-pin Hirose connector for trigger input and RS-232C control interface.
CV-A50 IR 5. Pin Assignment 5.1. 12-pin Multi-connector (DC-IN/VIDEO OUT, EXT.HD/VD IN) Type: HR10A-10R-12PB-01 (Hirose) male Seen from rear. Pin configuration is compatible with EIAJ standard Pin no. Signal Remarks +12 V DC input Video output Parallel with the BNC connector.
In the following schematic diagrams the input and output circuits for video and timing signals are shown. Jumper settings are shown as for factory default. For alternative connections refer to “10.1. CV-A50 IR emulating CV-M50 IR interfacing.” 5.3.1. Video output...
CV-A50 IR 6. Functions and Operations Apart from the standard continuous operation, the CV-A50 IR features three external asynchronous trigger modes (edge pre-select, pulse width controlled and start/stop) and a special frame-delay readout mode. Long integration time mode is also supported.
CV-A50 IR 6.2. Input-output of HD/VD Signals In the default setting the camera will accept external HD/VD signals on pin 6 and 7 of the 12 pin Hirose connector. If external HD/VD is applied, the camera will synchronize to it. If no external sync signals are applied, the camera will operate with its internal x-tal controlled sync.

CV-A50 IR 6.4. External Trigger Modes This camera has 5 external asynchronous trigger modes, which can be set by RS-232C commands. Edge Pre-select Mode.TR=1 Pre-selected exposure. (SM=0, SM=1) Pulse Width Control Mode. TR=2 Pulse width controlled exposure. Frame Delay read out mode. TR=3 PWC exposure read out by ext.
CV-A50 IR 6.5. Edge Pre-select Mode The leading edge of the trigger pulse initiates the exposure. The exposure time (accumulation time) is governed by the pre-defined shutter speed set by RS-232C. The resulting video is output as “odd field” for EIA and “even field” for CCIR, and appear 9H (EIA9 or 10H (CCIR) after the leading edge of WEN (polarity is user selectable).
CV-A50 IR 6.6. Pulse Width Control Mode The leading edge of the trigger pulse initiates the exposure. The exposure time (accumulation time) is governed by duration of the trigger pulse. The resulting video is output as “odd field” for EIA and “even field” for CCIR, and appear 9H (EIA9 or 10H (CCIR) after the leading edge of WEN (polarity is user selectable).
CV-A50 IR 6.7. Frame-delay read out Mode This mode allows simultaneous capture of multiple camera using a common external trigger pulse subsequent multiplexed (sequential) readout using a single input frame grabber, as the user has control over when the image is read out from the CCD sensor. The exposure starts at the falling edge of the ext.
CV-A50 IR 6.8. Long Time Exposure Mode The exposure time is the interval between 2 ext. VD pulses sent to the VD input of the camera (Pin No. 7 of the 12-pin Hirose connector). The exposure starts after input of the first ext. VD pulse, and ends after the next input of the next ext.
CV-A50 IR 6.9. Start/Stop Mode The exposure time is controlled by the interval between the ext. trigger and the ext. VD signal. The exposure starts at the first HD pulse after the falling edge of the ext. trigger, and stops 14.5 H after the falling edge of the VD pulse.
CV-A50 IR Important notes on using this mode:- • As the start of exposure will be synchronized with the internal H signal, the start of exposure may be shifted by max 1H. • To avoid this shift (jitter), synchronize the camera with an external HD and make sure that the trigger pulse aligns to the HD signal as shown in Fig.
All configuration of the A50/60 camera is done via the RS-232C port. 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.

CV-A50 IR 7.4. Internal Switch and Jumper Settings. 7.4.1 HD/VD input-output selection In the default setting the camera will accept external HD/VD signals on pins 6 and 7 of the 12 pin Hirose connector. The composite video signal from the camera will be synchronized to an external HD/VD source connected to the camera.

The CV-A50 IR has a slightly different pin configuration on the 12-pin Hirose connector, compared to the CV-M50 IR. This new configuration is compliant to the EIA-J standard. This means, however, that the CV-A50 IR is not completely backward compatible with the CV- M50 IR, in all cases (depending on the cable configuration).
Configuration shown in Bold+Italic is factory default setting Fig. 32. PK8275B main board 10.3. CV-A50 IR without sync on video output. For applications where the video output signal should be without the composite sync signal, it is possible to remove the sync signal by removing an internal resistor.
CV-A50 IR 10.4. Precautions Personnel not trained in dealing with similar electronic devices should not service this camera. The camera contains components sensitive to electrostatic discharge. The handling of these devices should follow the requirements of electrostatic sensitive components. Do not attempt to disassemble this camera.
