Overview
The N784 Series Media Converter is a standalone physical layer device that converts
between 10/100BaseT(X) and 100BaseFX segments of the same network. The converter
supports Link Fault Pass-through (LFP) for easy tracing of network link failures, and the
LFP function enhances the integrity and conformity of twisted pair (TP)-Fiber linking to
make the network easier to maintain. The converter is powered by an external power
adapter or USB port on the hosting device (e.g., PC).

Wiring the Power Inputs
Using the Converter with the AC-DC Power Adapter
1. Use DIP switch settings to enable power through the AC-DC Power Adapter
(refer to DIP switch settings section)
2. Verify that the AC-DC adapter conforms to your country’s AC power requirements and
then insert the power plug.
3. Connect the Converter to the network.
Note: Wear a grounding device to safeguard against damage due to electrostatic charge.
Using the Converter with power Over USB
1. Use DIP switch settings to enable power from the USB port
(refer to DIP switch settings section).
Note: Please ensure that the DIP switch is positioned on the USB side of the slider.
2. Install the USB cable. Plug type A connector in the PC’s USB port and the type B
connector in the Converter’s USB port (see Fig. 1).
3. Connect the Converter to the network.
WARNING
Make sure that the PC’s power is turned on. Otherwise the
Converter will not receive power.

Communication Connection
The Media Converter has one 10/100BaseT(X) Ethernet port, and one 100BaseFX (SC or
ST type connector) fiber port.
10/100BaseT(X) Ethernet Port Connection
The Converter supports auto MDI/MDI-X. Below are the pinouts for both MDI (NIC-type)
ports and MDI-X (HUB/Switch-type) ports. Also shown are the cable wiring diagrams for
straight-through and cross-over Ethernet cables.
• RJ45 (8-pin) to RJ45 (8-pin) Straight-Through Cable Wiring
(Tripp Lite N105, N001, N002 and N201 Series Cables)
• RJ45 (8-pin) to RJ45 (8-pin) Cross-Over Cable Wiring
(Tripp Lite N010 and N210 Series Cables)

Dip Switch Setting
(continued)
DIP Switch Dip Function
FX FDX FX at full duplex (default)
HDX FX at half duplex
LFP Enable Link Fault Pass-Through (default)
LFP DIS Disable Link Fault Pass-Through
TP FDX TP at full duplex (default)
HDX TP at half duplex when TP at Force
100 TP at 100M (default)
10 TP at 10M when TP at Force
AUTO TP at auto-negotiation (default)
FORCE Force TP at 10M or at half duplex
Note: • You must set DIP Switch 1 to “FORCE” when DIP Switches 2 and 3 are set to “10” and “HDX”, respectively
• For N784-001-SC, DIP Switch 5 must be set to “HDX”
• After resetting the DIP Switches, you must reboot the Converter to activate the new settings.
Link Fault Pass-Through
Note: The Link Fault Pass-Through (LFP) function is enabled using the DIP switch. Disable the LFP function by
setting the DIP switch to the LFP DIS position.
This media converter supports Link Fault Pass-Through (LFP) for TX/FX converter
applications.
Link status on one port is propagated to the other port to notify remote nodes. If the TP port
is unplugged, the converter stops transmitting over the fiber port, causing the remote fiber
link node to fail. The LED will show link failure on both the TP and fiber ports. If the fiber
link fails, the converter restarts auto-negotiation on the TP port, but stays in the link failure
state. This causes the remote TP node link to fail. The LED also shows the link failure on
both the TP and fiber ports. The figures below show normal status when the link succeeds,
and the error status when TP Cable A, Fiber Cable B, or Fiber Cable C fails to connect.
• Normal status via a pair of LFPs
• Status if TP Cable A is broken
• Status if Fiber Cable B or C is broken
Note: indicates LNK/ACT LED Lit indicates LNK/ACT LED Off

Link Fault Pass-Through
(continued)
WARNING
The LFP (Link Fault Pass-Through) function works only when
two converters working as a pair have LFP capability.
Furthermore, both LFP converters should be supplied by the
same manufacturer/vendor. If you are using an odd number of
converters, or models that don’t support LFP, then the LFP
function will not work.
