Instruction Manual – DXLink Fiber Transmitters and Receivers
DXLink Fiber Transmitters
DXLink Fiber Transmitters differ in the type of fiber optic transceiver they employ and the Directional Mode they use by
default. Duplex Transmitters default to providing simultaneous, bidirectional data transfer or can be configured to
provide unidirectional data transfer. Simplex Transmitters are designed to only provide a single direction of data flow
and not receive return data flow. The DXF-TX-MMD and DXF-TX-MMS have a multimode transceiver (the latch is
black or has a black label), and the DXF-TX-SMD and DXF-TX-SMS have a single mode fiber optic transceiver (the
latch is blue or has a blue label).
Note:
A DVI-D signal can be used (via a DVI-to-HDMI cable) into the Transmitter.
DXLink Fiber Transmitters – Front View
Components located on the front of the DXLink Fiber Transmitters (left to right):
Power LED
–
Indicates when the unit is powered on.
Digital Video and Audio LEDs
–
Indicate the presence of digital video and digital audio signals, including an
embedded audio signal on the HDMI path.
Analog Video LEDs
–
Indicate the type of analog video present through the unit: composite or Y/C;
Y/Pb/Pr or RGB; RGBHV or RGBS.
Program port
–
This port (USB mini-B connector) supports DGX Configuration Software for programming a
custom VGA or HDMI EDID.
IR LEDs – TX and RX LEDs indicate active IR communication.*
232 LEDs (RS-232 serial) – TX and RX LEDs indicate active serial communication (for details, see
page 57).*
NetLinx LEDs – Link/Act LED indicates network communication activity. The Status LED indicates that the
LAN connection is active.*
CEC LED – CEC is not currently supported.
USB LED – When illuminated, the LED indicates that the USB port is connected and enabled (for details, see
page 26).*
ID Pushbutton – Places the unit in ID Mode for setting the NetLinx ID (device only) and provides additional
functionality, such as placing the unit in Static IP Mode or DHCP Mode (for details, see page 68).
Local Out (video)
–
This HDMI connector can be used to send the source signal to a local monitor.
* 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.
