2.3  Pinout of the Interfaces:

PART II: ELECTRONIC CONTROL INTERFACE

Note:

The  SNAP  port  provides  two  trigger  signals 
to the stereo plug. For a camera which only 
needs a shutter-release signal, either trigger 
signals will work. For a camera which requires 
an extra “Focus” signal, both signals should 
be connected properly.

Input Voltage:  DC 7.5V (minimum) to DC 14V (maximum). Voltage not in this range might 
cause permanent damage to the motor controller or the hand controller.
Input Plug: Barrel type with 2.0mm I.D and 5.5mm O.D. Must be central positive.
Input Current:  At least 750mA.
Do not use an unregulated AC-to-DC adapter. When choosing an AC adapter, a switching 
power supply with 12V output voltage and minimum 750mA output current is recommend-
ed.
If the power voltage is too high, the motor controller will stop the motors automatically.

2.5 External Power Supply Requirements

Available for Canon, Nikon, Olympus and Sony cameras. See the table below to select the 

appropriate cable for your camera model; it can be ordered from the local Skywatcher dealer.
