For RGBHV video — Connect to five BNC connectors.

For RGBS video — Connect to four BNC connectors.

For component video — Connect to three BNC connectors.

RS-232 connection

6Remote port — Connect a host device, such as a computer or touch panel control, to the Digital Display Scaler via this 9-pin D connector for serial RS-232 control (figure 2-5).

See chapter 4, Programmer’s Guide, for definitions of the SIS commands and chapter 5, Scaler Software to install and use the control software.

Contact closure connection

6Remote port — The Remote connector also provides a way to select an input using a remote contact closure device. Contact closure control uses pins on the Remote connector that are not used by the RS-232 interface (figure 2-5).

To select a different input number using a contact closure device, momentarily short the pin for the desired input number to logic ground (pin 5). To force one of the inputs to be always selected, leave the short to logic ground in place. The short overrides front panel input selections.

Power connection

7AC power connector — Plug a standard IEC power cord into this connector to connect the scaler to a 100 to 240VAC, 50 Hz or 60 Hz power source. The front panel control and input selection buttons light in sequence during power-up, the LCD displays the product name and then cycles through the default messages.

Configuration

DDS 402 can be configured using either the front panel controls, the SIS, or the Windows Control program. See chapter 3, Operation, chapter 4, Programmer’s Guide, and chapter 5, Scaler Software for more information.
