Setting DIP Switch #2 to Set the DXLink Mode
#2 Toggle can be set to automatically or manually select the DXLink Mode (to either Extender or Endpoint) for a given
Transmitter/Receiver unit. Default state for #2 Toggle OFF is auto selection of DXLink Mode based on connection to
another device. When it's ON, the default is Endpoint Mode (used for Master controlled serial/IR data transfer).
Tip: Common setup scenarios and their DIP switch settings are provided in a table on page 46.
#2 Toggle Settings

* Any time the DXLink connection is re-established or power is cycled on a unit, the auto-discovery process will take
place, as long as the #2 Toggle remains in the OFF position.

** When standalone units require IR and/or Serial control by a separate NetLinx Master, then they need to be in
Endpoint Mode. Only one must be connected via the ICS LAN 10/100 port to the Master or to a LAN with the Master
on it. This requires #1 Toggle to be ON to enable the ICS LAN port. #2 Toggle needs to be ON to place the units in
Endpoint Mode (if needed), and #3 Toggle needs to be ON to enable network connectivity.
Note: On either setting, the DXLink Mode may be set via SEND_COMMANDs (see page 95). When
#2 Toggle is set to the OFF position, the auto-discovery process will overwrite the DXLink Mode setting.
However, when the #2 Toggle is set to the ON position, auto-discovery is disabled and the mode set by
SEND_COMMANDs will persist (i.e., the DXLink Mode setting cannot be overwritten).
Setting DIP Switch #3 for Network Connectivity
The #3 Toggle is used for enabling/disabling network connectivity of the DXLink Fiber Transmitter or Receiver. If
enabled it allows the Transmitter or Receiver to be configured to connect to a NetLinx Central Controller (used for
controlling the DXLink Fiber unit and allowing Ethernet traffic).
Tip: Common setup scenarios and their DIP switch settings are provided in a table on the next page.
#3 Toggle Settings

Note: After the #3 Toggle is set to ON, a network connection is established, and the NetLinx Studio screen is
refreshed, Transmitters and Receivers display in the OnLine Tree as Unbound NDP (Network Detect Proxy)
Devices. To facilitate IRL and KIT file transfers, they can be bound to the integrated NetLinx Master in the
switcher or to another NetLinx Master. A Virtual NetLinx Master can also be used for file transfers.
Instruction Manual – DXLink Fiber Transmitters and Receivers
OFF (default) – When the #2 Toggle is set to OFF, the Transmitter and Receiver will each auto-discover*
what type of DXLink equipment they are connected to and will automatically self-configure to be in one of
two DXLink Modes based on the connection:
Extender Mode – This mode is automatically selected when a TX and RX are connected directly to each
other (a standalone pair). The Transmitter and Receiver act like a simple extender, and serial data and
IR data are passed through them.
Endpoint Mode – This mode is automatically selected when a unit is connected directly to a DXLink port
on a switcher. Serial and IR operations are handled by the host providing control of endpoints. The Master's
programming specifies where IR and serial commands are sent (this is handled independently from the
routing of the video signals).
ON – When the #2 Toggle is set to ON, the auto-discover feature is disabled and the unit can be manually
set to either Endpoint Mode (default) or Extender Mode. In Endpoint Mode, when the unit is connected to
a switcher or a separate NetLinx Master**, IR and serial operation are only handled via the host.
OFF (default) – When the #3 Toggle is set to OFF, the Transmitter or Receiver will not try to connect to the
network and will not acquire an IP address.
ON – When the #3 Toggle is set to ON, the Transmitter or Receiver will attempt to connect to the network via
DHCP or static IP, depending on how the unit has been set up (see page 60). The Transmitters and Receivers
will not display in NetLinx Studio and will not accept commands or queries unless the #3 Toggle is ON.
