EXTERNAL POWER
This connection provides the main power for the camera. The camera operates from a DC
voltage between 5V to 24V. The current capacity of the power supply can be estimated by
dividing the camera’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.
