’
s power requirement by the external power voltage. It is also recommended to factor this
by about 50% as follows:
Power supply current capacity = (power specification / external voltage) x 1.5
The conductor used for this connection must be adequate for the current consumption of the
camera. For best performance the connection for
EXTERNAL POWER should be physically close to
the POWER GROUND connection.
SYNC INPUTS (1 and 2)
The input signals allow the camera to be synchronized to some external event. These signals are
optically isolated and require the signal common (
USER GROUND ). The camera can be programmed
to trigger on the rising or falling edge of these signals. The camera can also be programmed to
capture an image at some programmable delay time after the trigger event. These signals can be
driven from 5V to 24V with a current load of 5mA.
