CV-A11

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 camera scanning system should be set to the same as the external connected sync. In fig. 11 the time requirements to relation between VD and HD is shown.

The input is TTL level as factory setting. It can be 75 Ohm terminated by the internal switch on the PK8299 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 PK8299 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 PK8299 to IN for external VD/HD input. Factory default.

 

SW 2 on PK8299 to 75 for termination of VD/HD.

 

SW 2 on PK8299 to TTL for TTL level for VD/HD. Factory defaults.

 

SW 1 on PK8299 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.

See chapter 7.1 on how to select this mode.

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 15

 

“Programmable exposure” for full scanning

PE=1 through 523

 

PE for 1/2, 1/3 and 1/6 partial scan.

< 275, 195, 115

 

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.
