Quick Start Guide
This quick start guide describes how to install and use the hardened media
converter. This is the media converter of choice for harsh environments
constrained by space.
Physical Description
The Terminal Block and Power inputs
yDC Terminal Block Power Inputs: There are two pairs of power inputs
can be used to power up this media converter. Redundant power
supplies function is supported. You need to have two power inputs
connected to run the media converter, but the FAULT LED indicator
will light up to remind that the power redundant system functions
abnormal in case either PWR1 or PWR2 is dead. Media Converter,
however, continues working normally even fault LED indicator lights
up.
yDC JACK Power input: 12VDC.

One-Channel Media Converter
Ports
The Converter provides one TX port and one FX port. For the FX port, it
provides options of
yMulti-mode fiber using SC or ST connector or
ySingle-mode fiber using SC or ST connector or
yWDM fiber using single SC connector
For the TX port, it uses RJ-45 connector, auto-MDIX, and auto negotiates
10/100Mbps and full/half-duplex.
Port Settings
Port settings are made very simple by means of a DIP (Dual Inline
Package) switch at the front panel of the harden media converter.
DIP switch settings:

There are six pins on the DIP switch for port settings. Refer to the table below
for more details.

yFirst, disconnect the converter from the power. Then toggle Pin 2 of the
DIP switch to position 1 to enable the forced mode for TX port.
<NOTE>Pin 2 must be toggled to position 1 prior to speed and duplex mode
settings manually.

Or toggle Pin 3 to position 1 for 10Mbps speed.
yToggle Pin 4 to position 0 to force the TX port at full duplex mode. Or
toggle Pin 4 to position 1 for half duplex mode.
yToggle Pin 5 to position 0 to force the FX port at full duplex mode. Or
toggle Pin 5 to position 1 for half duplex mode.
yToggle Pin 1 to position 0 to disable link-fault-pass-through.
yToggle Pin 6 to position 0 to disable link down alarm.
yConnect the converter to the power again. The new setting will come into
effect then.

Link-Fault-Pass-Through
Connect the FX ports of two Media Converter A and B through the fiber
cable.
Link Fault of the FX port:
A Link Fault condition will be sensed on the TX port whenever the media
converter detects a Link Fault condition on the FX port. Thus, the 100,
LNK/ACT, and FDX/COL LEDs of the media converter would be off.
Link Fault of the TX port of the Media Converter A:
The Media Converter A: A Link Fault condition will be sensed on the FX
port whenever the media converter detects a Link Fault condition on the TX
port. Thus, the 100, LNK/ACT, and FDX/COL LEDs of the TX port of the
Media Converter A would be off.
The Media Converter B: A Link Fault condition will be informed to the FX
port of the Media Converter B. Then a Link Fault condition will be sensed
on the TX port of the Media Converter B whenever the Media Converter B
detects a Link Fault condition on the FX port. Thus, the 100, LNK/ACT, and
FDX/COL LEDs of the Media Converter B would be off.

Installation
This chapter gives step-by-step installation instructions for the Converter.
Selecting a Site for the Equipment
As with any electric device, you should place the equipment where it will
not be subjected to extreme temperatures, humidity, or electromagnetic
interference. Specifically, the site you select should meet the following
requirements:
The ambient temperature should be between -40 to 75 degrees Celsius.
The relative humidity should be less than 95 percent, non-condensing.
Surrounding electrical devices should not exceed the electromagnetic field
(RFC) standards.
Make sure that the equipment receives adequate ventilation. Do not block the
ventilation holes of the equipment.
The power outlet should be within 1.8 meters of the product.
DIN Rail Mounting
Fix the DIN rail attachment plate to the back panel of the media converter.
yInstallation: Place the media converter on the DIN rail from above
using the slot. Push the front of the media converter toward the
mounting surface until it audibly snaps into place.
yRemoval: Pull out the lower edge and then remove the media
converter from the DIN rail.

Connecting to Power
Redundant DC Terminal Block Power Inputs or 12VDC DC Jack:
12VDC DC Jack
Step 1: Connect the supplied AC to DC power adapter to the receptacle on
the topside of the media converter.
Step 2: Connect the power cord to the AC to DC power adapter and attach
the plug into a standard AC outlet with the appropriate AC voltage.

Redundant DC Terminal Block Power Inputs
There are two pairs of power inputs can be used to power up this device.
You need to have two power inputs connected to run the media converter,
but the FAULT LED indicator will light up to remind that the power
redundant system functions abnormal in case either PWR1 or PWR2 is
dead. Media Converter, however, continues working normally even fault
LED indicator lights up.
Step 1: Connect the DC power cord to the plug-able terminal block on the
media converter, and then plug it into a standard DC outlet.
Step 2: Disconnect the power cord if you want to shut down the media
converter.

Field Wiring Terminal: Use Copper Conductors Only, 60/75℃, 12-24 AWG
torque value 7 lb-in.
Alarms for Power and Port Failure
Step 1: There are two pins on the terminal block are used for power failure
detection. It provides the normally closed output when the power source is
active. Use this as a dry contact application to send a signal for power failure
detection.
Special note:
The relay output is normal open position when there is no power to the media
converter. Please do not connect any power source to this terminal to prevent
the shortage to your power supply.
