1.1 Introduction

The Comtech EF Data (CEFD) CMR-5940 Digicast PID Filter RS-422 – referred to
throughout this manual as the CMR-5940 – receives an MPEG-2 Asynchronous Serial
Interface (ASI) input and outputs an MPEG-2 RS-422 stream that has been filtered,
Program Clock Reference (PCR) restamped, and the egress rate is adjusted to the user’s
desired configured rate.

The CMR-5940 provides unparalleled price versus performance, and is currently the most
economical ASI-to-RS-422 conditioning device available.
