To connect an RS232 PTZ controller:
The RS232 controller cable should end with a female 9-pin RS232 connector.
 If you are only connecting the RS232 PTZ controller to the unit, and are not connecting any RS485 PTZ
controllers, plug the 9-pin RS232 connector directly into the RS232/485 connector on the rear panel of the
unit.
 If you are also connecting one or more RS485 PTZ controllers to the unit, plug the 9-pin RS232 connector into
the RS232/485 adapter supplied with the unit.

To connect an RS485 PTZ controller:
Each RS485 controller cable should end with two wires.
1. Use a wire connector to connect the wires to the RS485 connection wires of the adapter. Be sure to match the
positive (+) wire of the controller cable to the positive (+ red) wire of the adapter, and the negative ( -) wire of
the controller cable to the negative (- grey) wire of the adapter (see figure 3).

To connect multiple RS485 controllers to the adapter, insert the positive (+) wires of all of the controllers into
one slot in the wire connector, and the negative (-) wires of all of the controllers into the other slot of the wire
connector.

2. If multiple PTZ cameras are connected to the unit, configure each camera to use a different ID. For
information about how to do this, refer to the camera documentation.
3. Connect the RS232/485 adapter to the RS232/485 connector on the rear panel of the unit.
Connecting Sensors
Sensors are devices that detect events such as a door being opened or a light being turned on. Up to six dry-contact
input sensors can be connected directly to the unit. In addition, if you wish, you can connect either an ADAM Data
