Serial Data Transfer and IR Flow Control
FIG. 58 shows Bidirectional Mode serial data transfer and IR flow control when an Enova Digital Media Switcher with DXLink
Fiber, Duplex Boards is used with DXLink Fiber, Duplex units. The illustration also shows the video/audio signal path. The
switcher has an integrated NetLinx NX Central Control Processor which provides native AMX control at each remote
location fed by a DXLink Fiber unit. Control is sent over fiber cable (via the DXLink Fiber ports).
IMPORTANT:
For Duplex hardware in Bidirectional Mode connected to an Enova Digital media Switcher, w e 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.
NOTE:
For systems with DXLink Fiber, Simplex Boards, the return path is not available.
FIG. 59 shows a DXLink Fiber TX 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.
NOTE:
The TX 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 TX 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 55).
