Moxa Technologies ME61, ME61A, ME61B Quick Manual
ME61 Single-Strand Fiber Converter
First Edition, February 2004
1. Overview
MOXA ME61, Single-Strand Fiber Converter, is a standalone
physical layer device that converts between 10/100BaseT(X)
and 100BaseFX segments of the same network.
ME61 is designed with an optic Wavelength Division
Multiplexing (WDM) technology that transports bi-directional
and full duplex signals over a single-strand fiber cable
simultaneously. ME61 is powered by an external power
adapter or by the USB port of the host (e.g., PC or NB).
2. Package Checklist

• 1 ME61A or 1 ME61B
• AC-DC Power Adapter
• ME61 User's Manual
Please notify your sales representative immediately if any of
the above items is missing or damaged.

4. Wiring the Power Inputs
Using ME61 with the AC-DC Power Adapter
1. Use DIP switch settings to enable power through the
AC-DC Power Adapter (refer to Part 6. for DIP switch
settings).
2. Verify that the AC-DC adapter conforms to your country’s
AC power requirements and then insert the power plug.
3. Connect ME61 to the network.
Note
Wear a grounding device to safeguard against
injury due to electrostatic discharge.
Using ME61 with Power over USB
1. Use DIP switch settings to enable power from the USB
port (refer to Part 6. for DIP switch settings).
Note
Please ensure that the DIP switch is positioned
on the USB side of the slider.
2. I nstall the USB cable. Plug the type A connector in the
PC’s USB port and the type B connector in the ME61’s
USB port (see Fig. 1).
3. Connect ME61 to the network.
Warning Make sure that the PC’s power is turned on.
Otherwise, the ME61 will not receive power.

5. Communication Connection
ME61 models have one 10/100BaseT(X) Ethernet port, and
one 100 BaseFX (SC) fiber port.
10/100BaseT(X) Ethernet Port Connection
ME61 supports auto MDI/MDI-X. Below we show pinouts for
both MDI (NIC-type) ports and MDI-X (HUB/Switch-type)
ports, as well as cable wiring diagrams for straight-through
and cross-over Ethernet cables.

Note:
You must set DIP Switch 1 to "FORCE" when DIP
Switches 2 and 3 are set to "10" and "HDX,"
respectively
For ME61, DIP Switch 5 must be set to "FDX."
After resetting the DIP Switches, you must reboot
ME61 to activate the new settings.
7. Link Fault Pass-through
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 ME61
stops transmitting over the fiber port, causing the remote
fiber node link to fail. The LED will show link failure on both
the TP and fiber ports. If the fiber link fails, the ME61 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.
Note The Link Fault Pass-through (LFP ) fu nction i s
enabled by DIP switch. Disable the LFP function by
setting the DIP switch to the LFP DIS position.

Note ● indicates LNK/ACT LED Lit
○ indicates LNK/ACT LED Off
Warning
The LFP (Link Fault Pass Through) function works
only when two converters working in pairs have
this capability. Furthermore, both LFP converters
should be supplied by the same
manufacturer/vender. The connection comes from
LFP converters with odd models or non-LFP
converters will cease the LFP function.
