IV Connecting and Installing the Equipment

3 Connection Methods

EXTERNAL OUTFunctions:

Extended external output pins 1 and 2, both for strobe synchronizing output

This output is used mainly for synchronized firing of a stroboscope when capturing an image with the DS-L1.

Electrical characteristics of strobe synchronizing output are open-collector output, maximum input current = 10 mA, withstand voltage = 24 V, and internal resistance = 100 Ω.

The output pulse width is 67 ms.

This output can be connected to external devices that satisfy the following electrical characteristics. (See the diagram below.)

•Strobe synchronizing output is tied to a power supply line of 24 V or less through a pullup resistor R on the external device side.

•Inputs on the DS-L1 and external user device sides have the same GND potential or are left floating.

When plugging a stroboscope or other external device into the EXTERNAL OUT connector of the DS-L1, make sure the power for the external device is turned off. If the power for the external device remains on, your eyes may be damaged by unintended light emission.

(8) Connecting to a Power Supply

To prevent electric shock, turn off the power for the DS-L1 before making any connections. Complete all other connections before plugging into a power supply.

When connecting the DS-L1 to a power supply, always use the specified AC adapter (DS AC adapter) to which a dedicated power cord should be connected. Using the wrong AC adapter or power cord may lead to a fire or other dangerous conditions.

This product belongs to electric shock protection class I and must be connected to a power outlet with a protective ground terminal. If you misplace or damage the DS AC adapter power cord, please contact your nearest Nikon representative.
