Introduction

The 2090MDC HDTV Monitoring Downconverter enables a user to view
and evaluate an HDTV signal using a variety of low cost monitors
including NTSC/PAL composite or component analog and serial digital.
The 2090MDC is a two module set which includes a front media module
with indicators and controls and a passive rear module for cable connec­tions. Input signal standard is selected automatically. Each module fits into
any standard module location in a 2000 frame. In addition to downconver­ison capabilities, the 2090MDC offers the features listed below:

■

Accepts any of the following High Definition input signal standards:

■

1920/1035i 59.94/60Hz (SMPTE 240M),

Installation

Installation of the 2090MDC module is a process of:

Placing the passive rear module in a frame slot,

■

■

Placing the front media module in the corresponding rear slot, and

■

Cabling signal ports.

The 2090MDC module can be plugged in and removed from a 2000 Series

frame with power on. When power is applied to the module, LED indica-

tors reflect the initialization process (see Power Up on page 5 ).

Module Placement in the 2000 Frame

There are twelve cell locations in the 3 RU frame to accommodate either

analog or digital modules. The 2090MDC consists of a two module set con-

sisting of a front media module and a passive rear module. Each 2090MDC

media module plugs into the front of the 2000 frame mid-plane as illus-

trated in Figure 1. The passive rear module plugs into the corresponding

rear slot to provide the input and output interface connectors.
