*1 This is an external input signal.
*2 Exposure time (Te)
Te = Trigger pulse width + 5 µ s
(The effective trigger pulse width for the external
trigger shutter operation is between 2 µ s and 1/4 s.)
*3 Normal operation is resumed when the trigger
pulse width is 1/3 s or more. The trigger falling
edge restores external trigger shutter operation. At
this time, the 50 ms after the falling edge of the
trigger pulse is an external trigger input inhibition
area. There is no guarantee of operation for any
trigger input in this period.
*4 The internal VD signals are output as long as there is
no external input and the HD/VD signal input/output
switch on the rear panel is set to INT.

*5 In external trigger operation, the image is output
for the internal VD falling edge after the trigger
falling edge (1 and 2 in the figure). If the period
from the trigger falling edge to the internal VD
falling edge (T in the figure) is under 10 µ s, it is
not defined whether the image is output for the
internal VD falling edge or the image is output for
the next internal VD falling edge. (3 in the figure
shows that the image is output for the next internal
VD). In this case, see WEN since the image and
WEN make up a pair.
*6 With the XC-HR70, a signal synchronized with
VD cycle is not output.
Note
An image is not output correctly when the next trigger
is input before the image for the previous trigger has
been output.
