CV-A50 / CV-A60

1. General

The difference from the previous manual is that the CCD sensor in CV-A50 is changed to new types. Now the used CCD sensors are: ICX-408AL-6, 409AL-6, 418ALL-6, 419ALL-6. The CV-A50/A60 is a range of monochrome CCIR and EIA interlaced 1/2” and 1/3” CCD cameras, designed for automated application, featuring an extremely small housing and a wide range of unique functions. The asynchronous trigger can be set to work in several modes, to allow functions such as pulse width controlled shutter, programmable shutter speed and long time integration. All mode settings of the camera can be set up via an RS-232C interface, greatly reducing the need for mechanical switches of jumpers. The CV-A50 and CV-A60 output an analogue video signal, with composite sync.

5.3. Input and Output Circuits

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-A50/60 emulating CV-M50 interfacing.”

5.3.1. Video output

The video output is a 75 Ω DC coupled circuit. The BNC connector and pin #4 on the 12-pin connector is in parallel. Avoid double termination. The video DC level is shown with 75 Ω termination.

Fig. 4. Video output.

5.3.2. Trigger input

The trigger input is AC coupled. To allow a long pulse width, the input circuit is a flip flop, which is toggled by the negative or positive differentiated spikes caused by the falling or rising trigger edges. The trigger polarity can be changed. Trigger input level 4 V ±2 V. The trigger-input impedance is 1 kΩ. JP1 and JP4 are for alternative configuration for pin #10.

6. Functions and Operations

Apart from the standard continuous operation, the CV-A50/60 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.

6.1. Basic functions

Some of the primary camera functions need a general introduction before the operation modes are described. The list below shows the primary functions from the command list.

SM Shutter Mode Normal shutter, Programmable Exposure SH Shutter Speed Off to 1/10,000 second PE Programmable Exposure 1.5 H to 1023.5 H SC Scanning Format Interlaced, non-interlaced, (1/2 partial, 1/3 partial) TR Trigger Mode Normal, Edge, PWC, frame delay readout Long time exposure, start-stop FR Accumulation Field, Frame

The shutter SM can be set to normal (SM=0), where the exposure time is selected from 8 fixed step with the command SH, or programmable exposure (SM=1). Here the command PE allows up to 1023 steps with 1 period resolution (64 µs) for edge pre-select mode. For normal modes PE can be up to 312 for CCIR and 262 for EIA.

The scanning format SC can be selected between interlaced and non-interlaced sync signals. Further it is possible to select 1/2 and 1/3 partial scanning. It is not supported for the camera.

The accumulation FR can be field or frame. Fig. 9. show details for frame and field accumulation with shutter OFF, (left(, and shutter on, (right).

The accumulation in all trigger modes is H synchronous. The exposure will start at the first HD pulse after the trigger falling edge. Fig. 8. shows the details. In all triggered shutter modes, the shortest shutter time is limited to ≥1.5 H or 1/10,000. In trigger modes, the exposure time is not limited to the readout time. It can be longer.

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. The time requirements to the relation between VD and HD are shown in fig. 16. The input is TTL level as factory setting. It can be 75 Ohm terminated by the internal switch on the PK8277 board. SW2-1 for HD and SW2-2 for VD. On for 75 Ohm termination. To output the internal HD/VD signals on pin 6 and 7 the internal switch SW1-1 and 1-2 on the PK8277 board should be set ON. The output is TTL level from a 75-Ohm source. Refer to “7.4. Internal Switch and Jumper settings.” In trigger modes there are no continuous VD out. Only after an external trigger pulse, a VD pulse will be output.

To use this mode: Set function: SW 1 on PK8277 to IN for external VD/HD input. Factory default. SW 2 on PK8277 to 75 Ω for termination of VD/HD. SW 2 on PK8277 to TTL for TTL level for VD/HD. Factory defaults. SW 1 on PK8277 to OUT for internal VD/HD output. Input: Ext. VD in or int. VD out on pin 7 on 12-pin connector. Ext. HD in or int. HD out on pin 6 on 12-pin connector.

Important notes on using this mode

External sync system should follow the camera scanning system.

6.3. Continuous Operation (Non triggered)

For applications that do not require asynchronous external trigger (continuous operation). This is the factory default setting of the camera.

To use this mode: Set function: Trigger mode to “Normal” TR=0 Shutter mode “Normal” or “Programmable” SM=0, SM=1 “Shutter Speed” SH=0 through 7 “Programmable exposure” for CCIR PE=1 through 312 “Programmable exposure” for EIA PE=1 through 262 Polarity and other functions Input: Ext. VD on pin 7 on 12-pin connector. If used. Ext. HD on pin 6 on 12-pin connector. If used.
