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
The input is TTL level as factory setting. It can be 75 Ohm terminated by the internal switch on the PK8299 board.
To output the internal HD/VD signals on pin 6 and 7 the internal switch
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 Ω 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 |
| Ext. HD in or int. HD out on pin 6 on |
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 |
|
| Ext. HD on pin 6 on |
