7 2. INSTALLATION OF THE HARDWARE The optional power supply (ref 2460) can feed multiple multiswitches. Ref. Amount of products per power supply 9744MC 4 9746MC 2 9748MC 1 The four trunks are DC isolated from each other, so 13 V and 18 V can be supplied separately from trunk out to trunk in. All 4 LNB trunks should always be cascaded or terminated with a DC- blocked 75-Ohm terminator. All unused SCR/Leg ...

8 3. CONFIGURATION OF THE MODULE STB Power to Trunk Switch  OFF  This is the default state, as trunks will feed all cascaded units and the LNB. Power comes from DC inserted at the “DC Input” of 1 or more cascaded units.  ON  The STB will feed the unit and the LNB. This is only allowed when 1 unit is used in the system. From the moment 2 are cascaded, the position “OFF” should be sele ...

9 dSCR Modes: SCR mode: Slow blinking GREEN Legacy mode: Solid GREEN The 974xMC can work in two modes on each output independently – SCR Mode and Legacy Mode. The default mode is Legacy Mode. The module will automatic switch from Legacy to SCR mode upon the first DiSEqC command when a SCR set top box is connected. If SCR mode has been activated, that specific output needs to be powered-off to go back ...
