Powering the adapter from the LANC bus
PLEASE NOTE : This option is highly dependent on the capabilities of your camera! Please test before
using this power option to insure that your camera will supply the proper voltage to the controller
board!
The ALE716 adapter includes an alternative power scheme that will allow powering the adapter directly
from your camera’s LANC bus. However, the voltage supplied from the camera MUST BE greater than
6VDC in order for this option to work properly. As the battery is drained on the camera through normal
use, the voltage supplied on the LANC bus may drop below an acceptable level. If the operation of the
adapter becomes inconsistent while powering in this manner, make sure that the camera’s battery is
fully charged. Please be aware of this if you choose to power the adapter using this method.
The power input on the adapter is set at the factory to use the USB micro plug as the power source. To
switch to using power from the LANC bus, you must do the following:
1)
Remove the four screws on the adapter’s top acrylic panel and remove it.
2)
Next, locate the power supply option jumper as indicated below:
3)
Move the jumper block from the current (top) position to the lower position, connecting the
bottom two pins with the jumper block.
4)
Replace the top acrylic panel and the four screws.
