Overview DXLink Fiber, Duplex
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 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 75).
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 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 75).
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 75).
ICS LAN10/100 Connector
The ICS LAN 10/100 (RJ-45) connector provides for Ethernet 10/100 connectivity (e.g., receiving
SEND_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 (Serial) Port
The RS-232 serial data interface port is a 3-position screw terminal block which accepts data from the source device and
transfers it via the fiber optic cable to the RX, which 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 "Host" port on the rear of the TX connects to a PC. The Host port forwards HID keyboard and
mouse data received from a directed DXLink Receiver's USB port (the Receiver can be either Fiber or Twisted Pair).
For USB port information, see page 23.
