Video Input Connections
The video input section on the ScreenPro PLUS rear panel provides 16 (1600 series) or 12 (1200 series) universal
inputs. Each input can accept RGB, YUV, S-Video (Y/C), or composite (NTSC or PAL) video signals. The
connections for each input channel are made via five BNC connectors. Connection points for each type of video
signal are specified below.

Video Output Connections – Program Outputs
Two independently buffered Program outputs (one five wire BNC connection and one HD-15) are provided for each
output screen. Either of these outputs may be used to connect to the display device used for the presentation. The
second output is designed to support a local display in the event that the operator is unable to conveniently view the
presentation.
Both outputs provide RGB video signals. Connect the outputs labeled R,G, and B on the rear panel of the ScreenPro
Plus unit to the correspondingly labeled connectors on the output device.
The operator can select the type of output sync to match application requirements. Separate C (Composite) or
separate H/V (Horizontal/Vertical) sync modes are supported. Connect the C or H sync signals from ScreenPro Plus
to the correspondingly labeled connectors on the output device. If separate H/V sync mode is being used, be sure to
connect the V signal from the ScreenPro Plus to the correspondingly labeled connector on the output device.
Preview Output
One Preview output (on an HD-15 connector) is provided for each output screen. The Preview outputs are provided
to permit the operator to view the next source video to be displayed prior to initiating a transition. The Preview outputs
provide RGB video signals. Connect the outputs on the rear panel of the ScreenPro PLUS unit to the correspondingly
labeled connectors on the output device.
The operator can select the type of output sync to match application requirements. Separate C (Composite) or
separate H/V (Horizontal/Vertical) sync modes are supported. Connect the C or H sync signals from ScreenPro PLUS
to the correspondingly labeled connectors on the output device. If separate H/V sync mode is being used, be sure to
connect the V signal from the ScreenPro Plus to the correspondingly labeled connector on the output device.
Frame and Controller Connections
Connect the Controller to the ScreenPro PLUS Frame using the 25-pin serial cable provided with the unit.
Tally Connections
Tally outputs provide dry-contact relay closures between signal pairs or contact closures to ground whenever the
corresponding input source is selected for display on a Program output. The Tally outputs may be used to signal
when input devices (such as cameras) are “live”. Each contact has a rating of 1 Amp at 30 VDC and 0.5 Amps at 125
VDC. A mating connector (DB-25 female) is required (see diagram next page).
