Be sure to turn off the power to the DS-L1 and any equipment to be connected before making
connections.
When an external device is connected to the EXTERNAL IN connector on the DS-L1, the image
can be frozen or captured by trigger input from the external device.
Furthermore, if an external device is plugged into the EXTERNAL OUT connector, a strobe
synchronizing output can be obtained when capturing an image.
If you are preparing your own external device, use a device that satisfies the specifications
