6.3 RS-485

The camera adapts RS-485 in half-duplex pattern, which is a two-pin connectivity, as shown on the right picture.

Installer must pay attention to the polarity of these two pins – yellow wire is the POSITIVE end, and orange is the NEGATIVE. Communication between controller and camera will break and control will not function if they are reversely connected.

The RS-485 communication may run for 4,000 feet if the system network is properly built. Two important factors should be handled with care during the system build-up--- baud rate and termination impedance. More information about RS-485

are in sections “Protocol and Baud rate” and “Applications”.

6.4 Alarm Input and Alarm Output

This camera is equipped with 3 alarm inputs and one alarm output for intrusion management. Installers may connect the inputs to the various sensors and program the camera to move and monitor specific spots for monitoring when evens take place. Dwell time for monitoring is programmable, subject to the system. Refer to the diagram on right for function assignments of the alarm I/O.

Alarm inputs

This speed dome has three alarm inputs, and each input is given by the software a companion view preset. When trigger single is sent to alarm-in, the following reactions will be taken by the speed dome:

„The pan-tilt mechanism will move lens to the preset.

„The alarm-out port will act.

„Via RS-485, the console (control unit) will be notified
