AJA D4E Serial Digital Encoder User Manual — Introduction 3 Introduction The D4E SDI Encoder provides the lowest cost all-digital conversion of Component Serial Digital (SDI) to analog NTSC or PAL Composite or Y/C (S Video). The D4E is useful for monitoring, level and phase checking, dubbing, or desktop video applications. The D4E automatically adapts to NTSC or PAL video standards and outputs analog NTSC (525 line input) or PAL (625 line input).
User Controls The user interface for the D10CE is a 4-switch DIP accessible through a cut-out in the bottom of the unit. Use the DIP switches to configure output, pedestal, blanking, and enable or disable the test signal output. Switches 1 through 3 control the format of the output BNC. Switch 4 turns the test signal on and off. The exact function of each DIP switch and what it controls is described on the following pages.
AJA D4E Serial Digital Encoder User Manual — Installation : ON OFF Output 75% Color Bars (requires a valid SDI input) Normal Operation—no test signal is output Notes: 1. The D4E is programmed for a 1.3 MHz chroma bandwidth when operating in composite video mode. This provides the best quality video when encoding component digital video. However with lower cost monitors, it may be desirable to reduce the composite chroma bandwidth to 650 Khz to reduce the effects of cross-color artifacts.
Item Specification Output level matching 1 .5% or 10mv (All outputs are separately buffered) Power (AJA power supply model DWP) 5v DC regulated, 2 watt Size 5.1" x 1.
