Connecting Serial Port (RS-485 Communication)
 For PTZ control, connect the cable(s) to your keyboard or DVR. To connect multiple cameras to a
single controller, the RS-485 communication should be connected in parallel as shown below. If you are
connecting a single camera to a controller, you must terminate the camera. When connecting more
than one camera to a single controller, terminate the last camera on the communication line. era
The last camera means the camera farthest in cable length from the controller. Note that the total length
of the communication cable between a controller and the camera(s) on the same communication t
line must be less than 1.2Km.
 The RS-485 port of VS-570-HDSDI can be connected to external equipment such as PT receiver etc.
A PC client can send PT commands to the external equipment via the serial port.
When a decoder system instead of a PC client is connected to VS-570-HDSDI, the serial port and
that of the decoder system work in pass-through mode. That is, data from one port is delivered
to the other port and vice versa.
