Chapter 1 Introduction
Overview
The SAC6840N is a SD-SDI/ASI 2X1 switcher, supports clean switching, and the switching function of
which is finished based on internal circuit. When power failure happens, the signal is still through
depended on the relay located at back connector, simultaneously, the setting of output is not changed.
The module can work at two modes, either AUTO mode or MANUAL mode. To AUTO mode,
switching happens when alarm occurs or internal status changes. To MANUAL mode, remote control
