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 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 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.
