Setting DIP Switch #4
The #4 Toggle is used for placing Duplex units in Unidirectional Mode. If placed in the ON position, Unidirectional
Mode is enabled on the DXLink Fiber, Duplex Transmitter or Receiver. Only audio and video will transmit from a TX or
be received by an RX; the return optical data path will be turned off and will not try to establish connection. Ethernet, IR,
RS-232, and USB HID (keyboard and mouse data) will not be enabled, nor is NetLinx connectivity available. The
missing functionality can be provided in Unidirectional Mode by connecting the ICS LAN port to a Network (for details,
see "Unidirectional Mode LAN Configuration" on page 60).
After flipping the toggle, the Transmitter or Receiver must have its power cycled to reboot the unit into the mode.
Disabling the switch and cycling power will reboot the unit back into Bidirectional Mode.
DXLink Fiber, Simplex Transmitters and Receivers cannot change their Directional Mode: The toggle can be set to ON
or OFF.
Scenarios / DIP Switch Settings Table for Bidirectional Mode
Important: In a standalone pair with mixed hardware (one unit Duplex and the other Simplex), we
recommend setting the Duplex unit to handle Unidirectional communication (set #4 Toggle to ON). In a
switching system with mixed hardware (a mix of Duplex and Simplex boards and units) comprising a
complete switching run, the hardware will only support Unidirectional Mode – we recommend configuring all
hardware accordingly.
The table below contains the most common scenarios for setting up DXLink Fiber, Duplex Transmitters and Receivers
in Bidirectional Mode as a standalone pair or with other equipment.
Find the scenario in the table that you want to use and then set the DIP switches accordingly. A detailed
explanation of functions for each toggle is provided above and on the previous page.
Tip: Each toggle's ON position is toward the connectors on the rear of the DXLink Fiber units (see page 44).
Common Scenarios for Bidirectional Mode
TX/RX pair direct connection (Standalone Setup)*
AV signals only (plus serial/IR pass through)
AV with Ethernet pass through to networked device** (plus serial/IR pass through)
AV with NetLinx control of TX/RX unit and serial/IR ports, plus Ethernet pass
through to a networked device^
TX/RX connected to Enova DGX Switcher (Switcher Setup)
AV signals only
AV with Ethernet pass through to networked device**
AV with NetLinx control of TX/RX unit and serial/IR ports
AV with NetLinx control of TX/RX unit and serial/IR ports, plus Ethernet pass
through to a networked device^^
* Connection requires Duplex hardware with both fibers connected and in Bidirectional Mode (will not work in Unidirectional
Mode).
** Connect the ICS LAN 10/100 port on one of the DXLink Fiber units to the network device (e.g., laptop, IP controlled
projector, AMX ICSLan EXB Device).
^ Connect the ICS LAN 10/100 port on one of the DXLink Fiber units to the network device (e.g., laptop, IP controlled
projector, AMX ICSLan EXB Device) and connect the other unit to the network (the unit with #1 Toggle enabled).
^^ With both units connected to boards in an Enova DGX Digital Media Switcher (provides integrated NetLinx control),
connect the ICS LAN 10/100 port on one of the DXLink Fiber units to the network device (e.g., laptop, IP controlled
projector, AMX ICSLan EXB Device).
Important: When connecting a Transmitter or a Receiver in a standalone pair setup to a Master (or Virtual
Master) for upgrade purposes, #1 and #3 Toggles must be ON. #2 is only required on each module if serial
and/or IR control is required from the Master.
