Overview DXLink Fiber, Duplex

Instruction Manual – DXLink™ Fiber Transmitters and Receivers, Duplex
Fiber Optic Transceiver
The fiber optic transceiver receives digital video, embedded audio, Ethernet, and bidirectional control over fiber optic
cable from a DXLink Fiber Output Board, including digitally transcoded analog video signals. The DXLink Fiber path
supports HDCP. If the latch is black or has a black label, the SFP+ fiber optic transceiver is multimode; if the latch is
blue or has a blue label, the SFP+ fiber optic transceiver is single mode.
ICS LAN 10/100 Connector
The ICS LAN 10/100 (RJ-45) connector is for Ethernet 10/100 connectivity (e.g., receiving SEND_COMMAND
commands and downloading firmware update files). For pinout and LED information, see
page 42.
Note:
The #1 Toggle on the DIP switch must be set to ON to enable activity over this port.
RS-232 Port
The RS-232 (serial data interface) port is a 3-position screw terminal block on the Receiver which accepts data
(originally from a source device) via the Transmitter over DXLink Fiber and in turn transfers the data to the destination
device. The transfer of data can also be made from the destination to the source. In addition to being directly connected
to a device, this port can be connected as an independent native NetLinx control port from a networked NetLinx Central
Controller.
IR RX Port
The IR RX port is used for IR control (see page 25). This port is a 3.5 mm stereo jack. In addition to being directly
connected to a device, this port can be connected as an independent native NetLinx control port from a networked
NetLinx Central Controller.
IR TX Port
The IR TX port is used for IR control (see page 25). This port is a 2-way mini-Phoenix connector. In addition to being
directly connected to a device, this port can be connected as an independent native NetLinx control port from a
networked NetLinx Central Controller.
USB Port
The USB-mini A/B port on the rear of the Receiver supports keyboard/mouse commands. The HID keyboard and mouse
data is sent via the Transmitter (which supports the USB connection) to the PC (the Transmitter can be either Fiber or
Twisted Pair). For USB port information, see page 23.
HDMI Out Connector
The HDMI Out connector is for digital video and embedded audio. The HDMI connector has a center screw for locking
capability. The HDMI connector also supports a DVI-D signal (via a DVI-to-HDMI cable).
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.
Stereo Audio Out Connector
The Stereo Audio Out connector is a 3.5 mm stereo jack. This connector has an analog audio signal available for output
whether the embedded audio over the fiber optic cable originated as 2 channel digital or analog stereo. If encoded digital
audio or multi-channel audio paths are embedded on the HDMI path, then the local analog out will not be available.
Warning:
DXLink Fiber units use laser transceivers, which are Class 1 Eye Safe per IEC 60825-1/CDRH
requirements. While the Class 1 category indicates that the invisible laser used is safe, we recommend
avoiding direct eye exposure when using any optical fiber products (see the OSHA directive on page 13).
