Enova Digital Media Switchers - Hardware Reference Manual
The Transmitter receives an HDMI signal and an audio signal from a source device. The audio can be either digital audio
embedded with the HDMI signal, digital audio over S/PDIF, or analog stereo audio. Both the video and embedded audio
are transmitted over twisted pair cable to the RJ-45 connector on the DXLink Input Board. The signal is routed through the
desired DXLink Output connector to the DXLink Receiver, which in turn sends the HDMI signal with embedded audio on to
a destination device. Audio (whether embedded or not) received on the Transmitter can be output on the stereo audio
port (page 117):
NOTE:
For systems with special requirements
–
Before installing in the final location, place the equipment close together, so
a PC for control and the destination monitor can be seen simultaneously if adjustments are necessary. Adjustments can
be made using the System Configuration interface
Functions of DXLink Transmitters and Receivers
FIG. 43 shows the functions of DXLink Transmitters and Receivers and the example descriptions contain the device HDCP
key count when used in conjunction with DXLink Boards in an Enova DGX Digital Media Switcher:
Example A:
When a Receiver acts like a source, its key does not count. Source device sees 1 key (Transmitter).
Example B
: When a Transmitter acts like a sink, the source device sees 1 key (Transmitter).
Example C
: When a source device is connected directly to a switcher, the source sees 1 key (switcher input).
