Instruction Manual – DXLink Fiber Transmitters and Receivers
Serial Data Transfer and IR Flow Control
The illustration in FIG. 22
shows the bidirectional serial data transfer and IR flow control when DXLink Fiber, Duplex
units are used in Endpoint Mode with an Enova Digital Media Switcher. The switcher has an integrated NetLinx Central
Control Processor which provides native AMX control at each remote location fed by a DXLink Fiber Transmitter and
Receiver. Control is sent over fiber optic cable (via the fiber optic transceivers).
Serial data transfer and IR flow control work similarly in directly connected TX/RX pairs (Standalone Mode).
Important:
For Duplex hardware in Bidirectional Mode connected to an Enova Digital Media Switcher, we
recommend connecting the switcher to the network for all network connection needs. Network connections
via the switcher are faster and more reliable. Never connect both a TX and RX, a TX and switcher, or a
switcher and RX to the same network: Avoid network loops.
The illustration in FIG. 23
shows a DXLink Fiber Transmitter in Unidirectional Mode^ and a DXLink Fiber Receiver
in Bidirectional Mode with a setup that allows the units IR, USB, and serial communication via LAN when the system is
in Endpoint Mode with an Enova Digital Media Switcher
^ The Transmitter can either be Duplex configured for Unidirectional Mode or Simplex, which can only support
Unidirectional Mode. In either case, the fiber cable attached to the Transmitter has no data return path.

Important:
The fiber cable attached to the TX only
handles signals in Unidirectional Mode. The return
fiber path is disabled.
Caution:
In a source-to-destination signal run that includes hardware in more than one Directional Mode,
take precautions against creating network loops with hardware in Bidirectional Mode (see page 57).
