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.

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.

CV-A50 / CV-A60
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.
Important notes on using this mode
