This document describes a new device introduced by ST Microelectronics called SaTCR-1 (Satellite Channel Router), which is able to translate a transponder to any location in the satellite bandwidth (950-2150 MHz). Multiple SaTCR devices coupled with band-pass filters and RF matrix allow to combine transponders from different polarizations and bands on a single coaxial cable. The purpose of this document is to describe the AN2056 protocol extension used to control a LNB based on SCR technology.
