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 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.
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 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 |
| 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.
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 |
|
| Ext. HD on pin 6 on |
|
