Instruction Manual – DXLink Fiber Transmitters and Receivers
DXLink Fiber Multi-Format Transmitters
The DXLink Fiber Transmitters receive an HDMI signal or analog video signal (composite, Y/C, Y/Pb/Pr, RGB, RGBS,
or RGBHV) and an
audio signal from a source device. The audio can be either digital audio embedded with the HDMI or
analog stereo audio.
Either analog or digital video is transmitted out of the fiber optic transceiver. The active video selection is made using
one of two methods:
Automatic – selects digital video as the priority video input or analog video when digital video is not present.
Can be set to treat either the digital or analog video as the priority, which then defaults to the opposite if the
primary is not present.
Active SEND_COMMAND video input selection from a bound NetLinx Central Controller (usually the
integrated Central Controller on the Enova DGX).
Both the video and audio are transported over fiber optic cable to either an Enova DGX Digital Media Switcher or
directly to a DXLink Fiber, Duplex RX. The unit also has a local HDMI output connector on the front for sending the
video signal from the source directly to a local destination device. This local HDMI output connection supports the same
input resolutions contained in the first table in “Appendix E - Supported Input Resolutions” (see page 130).
The 232 port (RS-232) on the Transmitters supports bidirectional serial data via the fiber optic cable to/from the
232 port. In addition, the Transmitters have IR ports, which also send data via the fiber optic cable.*
* Configuration of Ethernet, IR, RS-232, and USB for units in Unidirectional or Data Link-lost Mode requires additional
information found in “Unidirectional Mode LAN Configuration” on page 60.
DXLink Fiber HDMI Receivers
The DXLink Fiber Receivers feature SmartScale
®
Technology (integrated EDID output scaling) to ensure an appropriate
output resolution, plus they support a Manual (override) option for setting up custom resolutions and a Bypass option
(see page 61).
The DXLink Fiber Receivers receive an HDMI signal and an audio signal over fiber optic cable from a DXLink Fiber
Output Board on an Enova DGX Switcher or directly from a DXLink Fiber Transmitter. They then send the signal on to
the destination. The audio output can be either digital audio embedded with the HDMI signal or analog stereo audio (if
the signal originated as a 2 channel audio format).
The 232 ports (RS-232) support bidirectional serial data via the fiber optic cable, which connects the DXLink Fiber
TX/RX units with the Enova DGX Switcher or with the DXLink Fiber Transmitter.*
* Configuration of Ethernet, IR, RS-232, and USB for units in Unidirectional or Data Link-lost Mode requires additional
information found in “Unidirectional Mode LAN Configuration” on page 60.
Note:
If a DVI-D signal is used (via a DVI-to-HDMI cable), the advanced audio support from HDMI will not be
available out the Receiver.
Note:
DXLink Fiber units support several different modes which are available for system setup and use. Brief
explanations of the modes are provided in the section “Quick Reference Tables for Modes” on page 29 along
with page references to detailed information.
