Hardware Reference Manual – DXLink Twisted Pair™ Transmitters/Receiver
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 Module. 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).
NOTE:
#2 Toggle settings do not apply to Wallplate TX & Decor Wallplate TX – leave #2 Toggle OFF.
TIP:
Common setup scenarios and their DIP switch settings are provided in a table on page 36.
#2 Toggle Settings
OFF (default) – When #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 and IR data is passed through
them.
Endpoint Mode – This mode is automatically selected when a module 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).
* Any time the DXLink connection is re-established or power is cycled on a module, the auto-discovery process will take place, as
long as the #2 Toggle remains in the OFF position.
ON – When #2 Toggle is set to ON, the auto-discover feature is disabled and the module can be manually set to either
Endpoint Mode (default) or Extender Mode. In Endpoint Mode, when the module is connected to a switcher or a separate
NetLinx Master**, IR and serial operation are only handled via the host.
** When standalone modules 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 modules 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 79). 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 (IP addressing) of the DXLink 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
unit and allowing Ethernet traffic).
NOTE:
Wallplate TX – Before the DIP switch toggles can be set, the mounting bracket must be removed (unscrew the four screws from
the bracket and set it aside). Decor Wallplate TX – Set switches before adding customer provided decor style front cover plate
(requires four screws).
TIP:
Common setup scenarios and their DIP switch settings are provided in a table on the next page.
#3 Toggle Settings
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 49). The Transmitters and Receivers will not display in NetLinx
Studio and will not accept commands or queries unless the #3 Toggle is ON.
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 a switcher or to another NetLinx Master. A Virtual NetLinx Master can also be used
for file transfers.
