Instruction Manual – DXLink Fiber™ Transmitters and Receivers, Duplex
ICS LAN 10/100 Connector LEDs
The following information applies to the LEDs on the ICS LAN 10/100 (RJ-45) connector on the units.
Link/Activity (L/A) Green LED:
On – Link status is active (when the Ethernet cable is connected and terminated correctly)
Off – Link status is not active
Speed Status (SPD) Yellow LED:
On – Speed status is 100 Mbps
Off – Speed status is 10 Mbps
Audio Type Precedence
The connectors for bringing audio into the system on the Transmitters are as follows:
HDMI In connector – Embedded audio signal
Digital Audio In jack – Digital audio signal (S/PDIF)
Stereo Audio In jack – Analog stereo audio signal
The hierarchy for audio type precedence* is listed in the following table for the Transmitters:
* Audio precedence as specified in the table above is applicable when the AUDIN_FORMAT_AUTO command is set to
ENABLE; this precedence can be overridden by SEND_COMMANDs (see page 76).
The audio selected by the Transmitter is embedded on the HDMI signal (if not already embedded) and sent to the
switcher via the fiber optic cable.
The DXLink Fiber RX will by default take the embedded audio it receives from a Transmitter** and output the
following types of audio:
HDMI Out connector – Embedded digital audio signal
Stereo Audio Out connector – Analog stereo audio signal
The audio output can be changed using the AUDOUT_FORMAT command (see page 70).
** These exceptions apply: In order for audio to be sent out of the analog stereo audio connector on the DXLink Fiber
RX, it must have originated or be embedded in the HDMI signal on the Enova DGX Digital Media Switcher or DXLink
Fiber Transmitter as a 2 channel signal (either analog stereo or 2 channel L-PCM). Multi-channel (>2 channel) L-PCM
formats will pass incomplete audio (only 2 of the multiple channels will be sent). All other audio formats will be muted
at the connector.
