6. Functions and Operations

6.1. Basic functions

Apart from the standard continuous operation, the CV-M40 features two external asynchronous
trigger modes Edge Pre-select and Pulse Width Control mode. Edge Pre-select mode can operate
with delayed read out, where the trigger falling edge starts a pre-selected exposure, and the
raising edge starts the read out.
These external trigger modes can operate with either H reset or H non-reset. In H reset, the
internal HD is reset on the falling edge of the trigger and the exposure starts. H non-reset need
external HD input. The exposure will be synchronized to the internal HD. It will start on the first
HD after the trigger negative going edge. In Pulse width control mode, the exposure stops after
the first internal HD
following the trigger rising edge.
H reset or H non-reset trigger mode cannot be selected by switch, jumpers or RS-232C. The
mode is automatic selected depending of the input pin used for trigger, and if external HD is
applied.

Note: In H non-reset trigger modes the exposure start can be delayed up to 1H. In pulse width
control modes jitter in exposure time can be up to 1H. To avoid this <1H jitter, the trigger
pulse should be synchronized to the HD as shown in fig. 8.

6.2. Input/Output of Timing Signals

Some signals can be input or output on different connector pins depending of camera mode and
jumper setting. Please refer to the principle diagram fig. 29. It shows input and output pins and
the jumper positions as it is for factory setting. The diagram can be useful for understanding the
following modes and jumper functions.
For details, please refer to chapter “7.2. Jumper settings”

6.2.1. Input of External HD/VD signals

The factory pre-set is HD/VD input on pin 6/12 and 7/12. The video output is synchronized with
external HD/VD signals if applied. If no ext. HD is connected, the camera will switch to the
internal X-tal controlled HD sync. If no ext. VD is connected, the camera will continue with its
internal VD. The external sync system should always follow the camera sync and scanning
system. The external HD/VD signal should be 4.0 Vp-p ±2.0 V from a 75 Ω source. The inputs are
factory set to TTL level (2.0 to 5.0 V). The input can be 75 Ω terminated by closing JP8/JP10 on
PK8273B board.
Input of external HD/VD for synchronizing the camera to an external source is possible in normal
continuous mode. Do not input external VD in trigger modes.

6.2.2. Output of Internal HD/VD signals

In order to output internal HD/VD signal 4.0 Vp-p from a 75 Ω source on pin 6/12 and 7/12, a
jumper setting is required. JP9/JP11on PK8273B board open, and JP12/JP13 short.
In normal continuous mode both the internal HD and VD can be output. In trigger modes the
internal VD will change to a WEN pulse. (Can be output on pin 7/12 by jumper setting).

6.2.3. Pixel Clock out on pin 9/12

Pin 9/12 is used for either pixel clock or WEN output. From factory none is output. Short jumper
JP7 (JP18 open) for pixel clock out. To avoid interference the pixel clock output should be
disabled if not used.

6.2.4. WEN out on pin 9/12

For applications where only the 12 pin connector is used, WEN can be output on pin 9/12 if JP18
is short (JP7 open). WEN active polarity is positive 1H. It can be changed to be active low by
JP22. The timing then depends of the actual mode.

6.2.5. Input of external trigger

The external trigger input use either the HD or the VD input circuit depending of the mode
setting. The external trigger signal should be 4.0 Vp-p ±2.0 V from a 75 Ω source. The trigger
inputs can be 75 Ω terminated by closing JP8/JP10 on PK8273B board.
Depending of which input circuit is uses for trigger input, the trigger mode will be H-reset or H
non-reset.
For a principle description of how it works, refer to fig. 29. with jumper in factory setting.

1) Trigger input on pin 6/12 will result in H reset mode.

2) Trigger input on pin 7/12 and external HD on pin 6/12 will result in H non-reset mode.

With trigger input on pin5/6:

1a) Trigger input on pin 5/6 will result in H reset mode. (JP5 short).
2a) Trigger input on pin 5/6 and external HD on pin 6/12 will result in H non-reset mode.
(JP5 open and JP20 short).

Please refer to chapter “7.2. Jumper settings” for details in mode settings.

6.3. Operation Modes

This camera can operate in 4 primary modes. 1 non-triggered, 3 external asynchronous trigger
modes. The triggered shutter can be HD synchronous or with H reset.
To avoid <1H time jitter in H non-reset mode, it is recommended to synchronize the trigger to
HD as shown I fig. 8.

1. Normal continuous Mode. Pre-selected exposure and long time exposure.

2. Edge Pre-select Mode. Pre-selected exposure.

3. Pulse Width Control Mode. Pulse width controlled exposure.

4. EPS with delayed read out Pre-selected exposure with delayed read out

For the 3 trigger modes, the shutter exposure can operate in 2 modes.

H reset:

The trigger leading edge will immediately reset the internal H phase and start the exposure.

This mode need no external HD input.

The delay from trigger falling edge to exposure start is 1.5 µsecond.

H non-reset:

The exposure will start synchronous with the first HD after the trigger leading edge.

This mode need external HD input.

To avoid 1 H jitter it is recommended to synchronize the external trigger to the external HD
signal as shown in fig. 8. The trigger falling and rising edge should be within the 4 + 1.5 µs.

Minimum trigger pulse width.
Edge Pre-Select mode H reset: >2µs
Edge Pre-Select mode H non-reset: >1H
Pulse Width Control: >2H
EPS with delayed read out: >3H + shutter time

Maximum trigger pulse width.
There is no fixed value for the maximum trigger pulse width. In pulse width control and frame
delay readout it can be up to about 2 second. Then the dark signal noise will be visible. It is
recommended to keep the trigger pulse short.

6.3.1. Continuous operation

This mode is used for applications not requiring asynchronous external trigger, but should run in
continuous operation.
The shutter time can be selected in 8 steps 8 steps, 1/125 to 1/12,000 sec. Via RS232C in 9 steps
1/60 (Off) to 1/120000. or programmable from 2H to 524H (Off). Binning or partial scan can be
used, but not together.
For settings refer to chapter “7. Configuring the camera.”
Refer to timing charts for details.

To use this mode:

Set: Rear switch SW1-5 OFF, SW1-6 OFF for Normal. For RS-232C select Continuous

trigger mode.
SW1-1 through SW1-3 on rear or RS-232C for shutter speed.
Other functions.

Input: If used, input Ext. HD and Ext. VD to pin 6/12 and 7/12.
[JP10 short for HD 75Ω termination. JP8 short for VD 75Ω termination.]

Note: Selection of shutter speed longer than the frame time in binning and partial

scanning will result in an exposure equal the frame time.

In partial scan, the shutter can not be completely off. Exposure is frame time –2H.

6.3.2. Edge Pre-select Trigger Mode

This trigger mode can operate in H reset mode or H non-reset mode.
In H reset mode the falling edge of the trigger will immediately reset the internal HD and start
the exposure. In H non-reset mode, where an external HD should be input, the exposure will
start at the first HD after the trigger. The shutter time can be selected in 8 steps, 1/125 to
1/12,000 sec. Via RS232C in 9 steps, 1/60 (Off) to 1/120,000. Programmable shutter from 2H to
524H (Off). Binning or partial scan can be used, but not together.
The resulting video signal will start to be read out after the selected shutter time.
To avoid up to 1H time jitter in H non-reset, it is recommended to synchronize the trigger to HD.
The falling edge of the trigger should be within 4.4 µsec. from the falling edge of the ext. HD.
(See fig. 8.).
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 been finished. (WEN negative
goes high). For partial scanning, refer to fig. 15.
For settings refer to chapter “7. Configuring the camera.”
Refer to timing charts for details.

To use this mode:

Set: Rear switch SW1-5 ON, SW1-6 OFF for Edge. For RS-232C select Edge Pre-Select.

6.3.3. Pulse Width Control Trigger Mode

This trigger mode can operate in H reset mode or H non-reset mode.
In H reset mode the trigger falling edge will immediately reset the internal H and start the
exposure. The exposure will end at the rising edge of the trigger, and the resulting video will be
read out. WEN will indicate the start of video read out.
In H-non-reset mode, where a continuous external HD is input, the exposure will start at the
first HD pulse after the falling edge of the trigger. The exposure stops at the trigger rising edge.
To avoid up to 1H time jitter it is recommended to synchronize the trigger to HD. The falling
edge of the trigger should be within 4.4 µsec. from the falling edge of the ext. HD. (See fig. 8.).
The resulting video signal will start to be read out after the trigger rising edge. The WEN pulse
indicates the start of valid video signal.
The trigger pulse width can be up to 2 second. Here the dark signal noise will be visible.
A new trigger pulse must not be applied before the video read out has been finished. (WEN
negative goes high). For partial scanning, refer to fig. 18.
For settings refer to chapter “7. Configuring the camera.”
Refer to timing charts for details.

To use this mode:

Set: Rear switch SW1-5 OFF, SW1-6 ON for Pulse. For RS-232C select Pulse Width

6.3.4. Frame delay read out Mode.

The trigger falling edge will start the selected exposure as for edge pre-select. The trigger
raising edge will start the resulting frame to be read out.
This mode allows simultaneous capture of multiple cameras using a common external trigger
pulse and sequential multiplexed read out to a single input frame grabber.
This trigger mode can operate in H reset mode or H non-reset mode.
In H reset mode the falling edge of the trigger will immediately reset the internal HD and start
the exposure. In H non-reset mode, where an external HD should be input, the exposure will
start at the first HD after the trigger. The shutter time can be selected in 8 steps, 1/125 to
1/12,000 sec. Via RS232C in 9 steps, 1/60 (Off) to 1/120,000. Programmable shutter from 2H to
524H (Off). Binning or partial scan can be used, but not together.
To avoid up to 1H time jitter in H non-reset, it is recommended to synchronize the trigger to HD.
The falling edge of the trigger should be within 4.4 µsec. from the falling edge of the ext. HD.
(See fig. 8.).
When the trigger signal rise, the resulting video signal will be read out.
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 been finished. (WEN negative
goes high). For partial scanning, refer to fig. 21.
The trigger pulse width should be >3H longer than the pre-selected exposure time.
The maxim trigger pulse width (or delay) should be <2 seconds. Here the dark signal noise will
be visible.
For settings refer to chapter “7. Configuring the camera.”
Refer to timing charts for details.

6.4. Other Functions.

Shutter speed.

The shutter speed can be set by the rear switch SW1-1 through 1-3 in 8 fixed steps from 1/125 to
1/12,000 second.
Via RS-232C it can be set to 9 fixed steps from 1/60 (Off) to 1/12,000 sec. Further it can be
programmed with 1H step from 2H to 524H (Off).

Readout mode.

Normal full frame readout or binning can be selected by SW1-4. The binning is vertical 2:1,
where the pixel values from 2 adjacent lines are added and read out as a single line. The frame
rate is 120. Binning will not work together with partial scanning.
With RS-232C the binning function is found in the “Frames Mode” menu.

Trigger modes.

The 4 modes can be selected by SW1-5 and SW1-6, or via RS-232C in ”Trigger Modes” menu.

Format.

Full or partial scanning can be selected by rear SW1-7. With partial selected, the scanning
format are set by internal jumpers JP14 through JP17. (1/2, 1/4, 1/8 or 1/16 partial). Factory
setting 1/4.
With RS-232C the partial scanning is found in the menu “Frame Modes”. Here it is also possible
to program the partial scanning with 1line steps from 15H to 413H.

(Note: Programmable partial scan is not supported with timing diagrams.)

Control.

Switch SW1-8 selects if the camera is controlled locally by switch and jumpers or via RS-232C.

Gamma.

Gamma can be set to 1.0 (linear) or 0.45 by internal jumpers JP1 and JP2. Factory setting 1.0.
If JP1 and JP2 is open, the gamma selection can be done via RS-232C.

WEN polarity.

The WEN output pulse is positive going 1H wide as factory setting. It indicates that the resulting
video signal is read out. With the internal jumper JP22, the WEN pulse can be changed so it is
low during video readout. Refer to timing diagrams for details.

Gain settings.

As factory setting the video gain can be controlled by the rear potentiometer.
Via RS-232C the video gain function has 3 modes.

1. Automatic Gain Control. AGC. Here the gain is automatic controlled to keep the video

level constant within a 12 dB range. The level is given by the AGC reference value.

2. Manual Gain Control. Here the gain level is set by Manual Gain Level via RS-232C.

3. Hardware (Rear potentiometer) where the gain can be set by the rear potentiometer.

AGC reference level.
The AGC reference level can be set by RS-232C only. The level is adjusted so the automatic gain
control circuit AGC will keep the video level constant. Normal video output 700 mVpp ±30 mV.

Black level.

RS-232C only. Black level (or set-up) can set the video level for black. Normal 20 mV ±2 mV.

White clip level.

RS-232C only. Is set to clip highlighted video signal peaks. Normal clip level is 800 mVpp ±30 mV.

7.3. Camera Control Tool for CV-40

From www.jai.com Camera Control Tool for Windows 98/NT/2000 can be downloaded.
The control tool contents a camera control program and tools for making your own program.
For the integrator and experienced user, the Camera Control Toll is much more than a program
with a window interface. It also provides an easy and efficient ActiveX interface built for MS
Windows 98, ME, NT and 2000. The OCX interface has the ability to connect to the camera using
the serial interface of the PC by reading and writing properties for the camera. This integration
requires simple programming skills within Visual Basic, Visual C++ or similar languages in a
Microsoft Windows environment.
Below the different windows are shown.

Fig. 30. Camera control tool windows.

7.3.1. Default settings at power up

With the camera rear switch SW1-8 “CONTROL” in “RS 232C, the camera will start with the
settings stored in user settings. The user settings can only be stored via RS-232C.
If the camera rear switch SW1-8 “CONTROL” is in “Local”, the camera will start with the settings
given by the switch and jumper setting.
