ADPRO FastTrace, Issue 5 1 - 9
1.7 Setting the Video Standard
ADPRO FastTrace can be set to operate using either PAL (CCIR) or NTSC (RS170) video standards. Once a standard
has been selected, all video inputs and the Monitor output (Composite video) will be configured to use the same
standard.
To set the required video standard, use the Configuration DIP switch on the rear panel.
Configuration Switch # 10 ON = NTSC
OFF = PAL
1.8 Video Input Connections
Depending on the model, up to 20 video sources can be connected via the female BNC sockets. The sources should
generate a 1.0-volt peak to peak composite colour or black & white video signal when terminated with a 75-ohm load.
A combination of colour and black & white cameras can be used. No external camera or system synchronisation is
required.
To ensure high picture quality, each video input must be terminated either at the chassis itself or by other external
equipment. The Terminated option in the Camera Details menu allows individual channels to be terminated with 75-
ohm or left un-terminated, for example, when the video signal is looped out to other equipment such as a video monitor
or video matrix switcher. The external equipment must provide the channel termination. The default menu option is
Terminated.
NOTE
To be configured correctly, this switch must be set before power on.
WARNING
Video terminations are OFF when power is removed.
The video terminators on the ADPRO FastTrace will disconnect when power to the unit is
removed. If the video inputs are also connected to other equipment, the ADPRO FastTrace
should NOT be used to provide a 75-ohm termination point.
WARNING
Installations in Lightning Prone Areas
In lightning prone areas, in-line coaxial lightning arresters should be used on the video
cables. The arresters should be installed at the cable entry of the building that houses the
ADPRO FastTrace. Cameras should also have suitable lightning protection rods installed as
close to them as possible. The use of fibre optics to provide electrical isolation on the video
signals is strongly recommended in high-risk areas.
