Wiring the Audio Output Connector (DSC 401 A Only)
The output can contain de-embedded audio from the input source (two-channel LPCM only) or the analog input can pass
through. The analog output and the embedded digital audio outputs share volume adjustment controls (applies to analog
or LPCM-2Ch inputs only). If multi-channel formats (such as Dolby/DTS or multi-channel PCM audio) are used, the analog
output is muted and volume control has no effect on the embedded output.
6.
Connect to a network (DSC 401 A only, optional)
— For remote control, connect the unit to a network via the RJ-45
), enabling configuration of the DSC via SIS commands, PCS or Toolbelt software, or the DSC 401
and 401 A web page. The LAN port supports PoE, which allows PoE network equipment to power the DSC 401 A.
NOTE:
An external power supply is not required for a DSC 401 A using PoE.

If not using the provided pre-wired power supply, wire a 2-pole
captive screw connector (provided) to your power supply as
shown in the image at right.
