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 Central Controller’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 Central Controller **, IR and serial operation are only handled via the host.
** When standalone modules require IR and/or Serial control by a separate NetLinx Central Controller, then they
need to be in Endpoint Mode. Only one must be connected via the ICS LAN 10/100 port to the Central Controller or
to a LAN with the Central Controller 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 “APPENDIX C: ICSP Commands”
section). 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, default setting is OFF, the transmitter and receiver will not
try to connect to the network and will not acquire an IP address;
Setting DIP Switch #4 is Reserved.
Note:
For easiest access to the DIP switch toggles, we recommend setting them before installation.
DIP switch settings on any of these DXLink products are read only on reboot. After the settings are read, any
adjustments of the toggles will not be implemented and will not affect the system.
#3 Toggle Settings
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).
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. The Transmitter and Receiver 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
Central Controller
in a switcher or to another
NetLinx
Central Controller
. A Virtual NetLinx
Central Controller
can also be used for file transfers.
