Installation and Setup

Instruction Manual – DXLink Fiber™ Transmitters and Receivers, Duplex
Avoiding Network (Ethernet) Loops
Only one connection to a LAN is permitted within a switching system with DXLink Fiber support.
Network loops must
be avoided
(see FIG. 11).
Example
In the example in FIG. 11, a network loop was created when the Enova DGX 16 was connected to a LAN and one of its
DXLink Fiber Transmitters was connected to the same LAN. The Transmitter must be disconnected from the LAN. The
same problem would also occur if an enclosure and one (or more) of its DXLink Fiber Receivers were connected to a
common LAN.
Remember to avoid network loops.
DIP Switch Location
Tip:
For easiest access to the DIP switch toggles, we recommend setting them before installation.
Important:
When setting the DIP switch toggles, make sure any toggles that need to be ON are flipped
toward the AMX sticker.
DIP switch toggles for enabling/disabling special Receiver/Transmitter functionality are located on the bottom of the
Receiver and the Transmitters.
Important:
DIP switch settings on all DXLink Fiber units are read only on reboot. After the settings are read,
any adjustment of the toggles will not be implemented and will not affect the system.
Caution:
Be careful not to create a network (Ethernet) loop.
