Figure 5: RS232/485 adapter
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 serial port connector on the rear panel
of the unit.
Connecting Sensors
Sensors are devices that detect events such as a door being opened, brakes being pressed, or
high G-force pressure. Up to four dry-contact input sensors can be connected directly to the
unit. In addition, if you wish, you can connect an ADAM Data Acquisition Module to the
unit. The ADAM module makes it possible to connect up to 16 additional sensors to the unit.
Sensor 1 and Sensor 4 can be used as switches instead of sensors. The switches can be used to
activate outlines and to change the display on a CCTV monitor.
Connecting a Sensor Directly to the Unit
The unit has four Input connectors (In1 In4). You can use these connectors to connect up to
four dry-contact input sensors directly to the unit. Alternatively, In1 and In4 can be used to
connect switches as follows:
In1: If you are defining more than one outline (alternate sets of recording and event-
handling settings), you can connect a toggle (on-off) switch to In1 instead of a sensor.
