8.7.7 Electrical interface (pin assignment)
For information about voltage levels (LVCMOS) of input (e.g. trigger) signals, see section:
5.1.4
You should check for correct input voltage levels.
Non-compliance can result in irreparable damages to the allPIXA pro camera!
Cabling requirements:
- The connection cable from camera to LED controller has to be fully shielded
- Use the
same
ground potential for all devices (cameras, LED-Drivers, shielding for all
cables, …) Also use 0V ground pins for ground potential at the controller
- *** TBD- The max length of the cable between camera and LED controllers is 5m ***
Pin no.

Out 1
– Out 4:
LED trigger output signal for channel 1
– 4
0V:
0V signal ground potential for use with Out 1-4 at the LED controller
NOTE I
Always use 0V ground signal level of the camera in addition to the OUT
channels for the signal levels at the LED controller.
8.7.8 I/O port configuration
For the operation of flash control,
the selected output ports (Out 1…4) are allocated
automatically if flash control is activated.
Make sure that the ports are not in use for other functionality. Any definitions for this output
channels in the I/O Configurator (
) are ignored as soon as flash control is activated.
