DXLink Fiber Transmitters – Rear View
Components located on the rear of the DXLink Fiber Transmitters (from left to right):
Power Jack
The power receptacle is a 2.1 mm DC jack for connecting power. Power comes from the locally connected DC supply
of 12 V. The automatically adjusting universal 110/220 IEC power supply is provided. The power supply is ENERGY
STAR
®
qualified to ensure maximum efficiency and savings.
Video In Connector
The Video In connector on the TX is an HD-15 connector for analog video (composite, Y/C, Y/Pb/Pr, RGB, RGBHV,
or RGBS). Pinouts for analog video are on page 128.
Note:
When an analog video source cable is plugged into the TX, one of the Analog Video LEDs on the front
of the TX and the Video LED on the RX (connected directly or via the switcher) turn green to show the type of
video that is present through the system.
HDMI In Connector
The HDMI In connector is for digital video and embedded digital audio. When more than one audio signal is present and
the default “auto” mode is enabled, HDMI embedded audio takes precedence over S/PDIF and analog audio.
When a NetLinx Central Controller is connected, an audio format SEND_COMMAND is available (the TX must be set
for network connectivity via the #3 Toggle) to select the desired audio source (see page 86).
The HDMI connector has a center screw for locking capability. The HDMI connector also supports a DVI-D signal with
the use of a DVI-to-HDMI cable.
Note:
When a digital video source cable is plugged into the HDMI connector, the Digital Video LED on the
front of the TX and the Video LED on the Receiver (connected directly or via the switcher) turn green to show
that video is present through the system.
Stereo Audio In Jack
The Stereo Audio In jack is a 3.5 mm stereo jack. By default, the stereo audio jack will be third in priority behind the
embedded audio on the HDMI input and digital audio on the RCA connector.
When a NetLinx Central Controller is connected, an audio format SEND_COMMAND is available (the TX must be set
for network connectivity via the #3 Toggle) to select the desired audio source (see page 86).
Digital Audio In Jack
The Digital Audio In jack is an RCA jack for an S/PDIF audio signal. When more than one audio signal is present and
the default “auto” mode is enabled, HDMI embedded audio takes precedence over S/PDIF, which takes precedence over
analog audio.
When a NetLinx Central Controller is connected, an audio format SEND_COMMAND is available (the TX must be set
for network connectivity via the #3 Toggle) to select the desired audio source (see page 86).
