Hardware Reference Manual – DXLink Twisted Pair™ Transmitters/Receiver
Avoiding Network (Ethernet) Loops
CAUTION:
Be careful not to create a network (Ethernet) loop.
Only one connection to a LAN is permitted within a switching system with DXLink support.
Network loops must be avoided
(see
FIG. 17). This applies to systems with DXLink Twisted Pair Modules
and/or
DXLink Fiber, Duplex units in Bidirectional Mode.
Example
In the example in FIG. 17, a network loop was created when the Enova DGX 16 was connected to a LAN and one of its DXLink
Transmitters was connected to the same LAN. The DXLink Transmitter
must
be disconnected from the LAN. The same problem
would also occur if an enclosure and one (or more) of its DXLink Receivers were connected to a common LAN.
Remember to avoid
network loops

NetLinx Binding of DXLink Modules or Wallplates with an Enova DGX/DVX
NOTE:
If a DXLink module or wallplate has been configured for auto-setup mode and then auto-setup mode has been disabled, the
unit may take longer to appear in NetLinx Studio than expected (1-2 minutes).
DXLink Transmitters and Receivers
must
have their DIP switch toggles set before they will display as part of an Enova DGX system in
NetLinx Studio (v4.0 or later is required). DIP switch information, including settings for common scenarios, is on the next three
pages.
In NetLinx Studio, the DXLink TXs and RXs can be bound to the integrated Master by right-clicking on the device and selecting
Network Bind/Unbind Device. This is considered the traditional method of binding. If the integrated Master runs on a 100 Series
CPU, see the
Hardware Reference Manual – Enova DGX 100 Series Digital Media Switchers
for auto-setup information (which does
not require binding).
To bind DXLink units to Enova DGX integrated Master:
1.
Verify the following:
a.
Verify that an Ethernet/RJ-45 cable is connected from the Enova DGX Switcher’s integrated Master to the network
(e.g., from the switcher’s LAN 100/1000 port to a LAN).
b.
Verify that the target Transmitter or Receiver is connected via its DXLink connector to a DXLink Input or Output Board
(respectively) on the switcher.
c.
Verify that the switcher is powered on.
2.
Launch NetLinx Studio and open the OnLine Tree.
3.
Bind the target Transmitter or Receiver to the integrated Master:
a.
Select and right-click the TX or RX.
b.
From the context sensitive menu, select Network Bind/Unbind Device (be sure the check box is selected).
c.
Click OK.

NOTE:
A network loop is created when
an enclosure and one or more DXLink
Transmitters or Receivers within the
system are connected to a common
LAN (or when two DXLink Modules are
connected to the same network as a
standalone pair).
