4.3 External Input Mode
In the External Input Mode, the user can’t make any flash rate
adjustments. The flash rate is a function of the input signal. This mode
is used to synchronize the flash to an external event (for example, from
an optical sensor) to stop or freeze motion. The flash will be triggered
on the rising or falling edge (menu selectable) of the external input
pulse.
The strobe is in the External Input Mode whenever there is a plug in
the input jack. When the strobe is in the External Input Mode,
EXT
will
be displayed.

T FUNCTION
button and then the
TACH
button. The
