This section describes the following:
• The I/O terminal connector
• Power connections
• The RS-232 D-Sub Connector
I/O Terminal Connector
The 10-pin I/O terminal connector provides the interface to a solid state relay output, two digital photo-coupled
inputs, RS-485, GND and auxiliary power.
The terminal connector is used in applications for e.g. motion detection, event triggering, time lapse recording,
alarm notification via e-mail, image storage to FTP locations, etc.
• Input - Used for connecting external alarm devices and triggering images for specific alarm-based
events. The input is typically connected to a motion detector or any other external security device, and
images can be uploaded whenever the detector is activated. Maximum 18V DC is allowed on the input.
• Output - This can drive a maximum load of 50V DC at 100mA directly or heavier loads by connecting
additional relay circuitry. If the output is used with an external relay, a diode must be connected in
parallel with the load for protection against any voltage transients.
Caution!
Connecting AC to
the
inputs/outputs
will damage the
