3.1 Single Camera Connection
Remote Control
The user is allowed to operate the camera from a short distance. Four video
interfaces are available for the user to connect PTC-120 to a display device as a
standalone device. The four video interfaces are DVI, C-Video, 3G-SDI and
Component. In the following four scenarios, PTC-120 streams to the display device
as a standalone device and a remote control unit (Page 14) is provided for the user
to adjust camera settings.
PTC-120 to an HDTV or a computer monitor (DVI)
(Cable Optional)
PTC-120 to a TV (C-Video) (Cable Optional)
PTC-120 to a monitor (3G-SDI) (Cable Optional)
PTC-120 to an HDTV or a TV (Component) (Cable
Optional)

10
SONY VISCA Compatible Keyboard
In addition, The PTC-120 Camera can also be controlled remotely using a SONY
VISCA compatible keyboard. Connect the camera as illustrated in the diagram
below whereby a SONY VISCA compatible keyboard is connected to control the
camera via RS-232 interface and the camera video output is connected to the
monitor via one of the four available video interfaces. The single camera system
setup can also be realized with RS-422 interface as shown in the second diagram.

3.2 Multiple Cameras Connection
The PTC-120 camera can also be used in an environment where multiple cameras
are required. With RS-232 INPUT/OUTPUT ports, the user is allowed to cascade up
to seven cameras, which are subsequently controlled by either a computer (Please
download a utility program first from http://www.serialporttool.com/PTZ.htm in
case you need to control the camera via a PC) or a SONY VISCA compatible keyboard.
RS-232C and RS-422 system setups for connection of multiple cameras are
illustrated in the respective diagrams below.
