DIN Rail Mounting of the Converter
The aluminum DIN Rail attachment plate should already
be affixed to the back panel of the Converter. If you need
to attach the DIN Rail plate, assure that the stiff metal
spring is situated towards the top. Attaching the
Converter to the DIN rail is easy, just align, and attach
the top rail, then press down and snap forward the
Converter to snap in the bottom rail, as shown in the
figures below.
The setup of the Converter can be performed using the
following steps:
• The surface must support at least 600 gm for the
Converter.
• The power outlet should be within 1.82 meters (6 feet)
of the Converter.
• Visually inspect the power adapter and make sure

9
that it is properly connected.
• Make sure that there is proper heat dissipation from
and adequate ventilation around the Converter. Do
not place heavy objects on the Converter.
Wall Mounting the Converter
The Converter can also be installed by wall mounting.
The backside casing provides space for two screws each
side. Identify the exact location at wall by placing the
Converter and marking the screw positions. Use the
screw (include in the package) and snug them well to fix
the Converter.
Power Inputs
Use the provided power adapter for power supply. Plug
the power adapter’s DC plug into the Converter’s DC-IN
jack and then power adapter into an electrical outlet.
Power Adapter: Only use the recommended specific
Power adapter provided with Converter. Check the technical
specificationsectionfor information about thepower input voltage.
Since theConverter does not include apower switch, pluggingits
power adapter into a power outlet will immediately power it on.

Fiber Connection
When connecting fiber cable to the Converter, be sure
the correct type – ST or SC - connector is used. Follow
the steps below to properly connect fiber cable:
1. Remove and keep the ST/SC port rubber
covers. When not connected to a fiber cable,
the rubber cover should be replaced to protect
the optics.
2. Check that the fiber terminators are clean. You
can clean the cable plugs by wiping them
gently with a clean tissue or cotton ball
moistened with a little ethanol. Dirty fiber
terminators on fiber optic cables will impair the
quality of the light transmitted through the
cable and lead to degraded performance on
the port.
3. Connect one end of the cable to the ST/SC
port on the Converter and the other end to the
ST/SC port on the other device.
4. Check the corresponding port LED on the
Converter to be sure that the connection is
valid. (Refer to the LED chart)
Warning Because invisible laser radiation may be emitted from
the aperture of the port when no cable is connected, avoid
exposure to laser radiation and do not stare into open apertures.

11
Serial Connection
The 5-pin terminal block connector is provided at the
front panel of the Converter. During shipping, the
removable green terminal block may already be detached
from the five pin terminal contact point. It may be easier
to attach the serial cable wires to the green terminal
block if it has first been unplugged from the terminal
contact point on the Converter.
On the terminal block, use a flathead screwdriver to
loosen the screws and then insert the related cable as
shown in the figure below. Tighten screws until snug.

LED Indicators
The Converter has following LEDs.
Power Indicator (PWR): This LED lights green when the
Converter is receiving power from input. It is located
beside the power adapter pin.

DIP Switch Settings
DIP Switches allow for the user to manually
enable/disable external alarms, 2-wire / 4-wire cable
mode, and TMR functions. The figure below shows the
DIP switch control.
DIP 1 (N/A)
DIP 2 (N/A)
DIP 3 (2-wire / 4-wire) Enable the serial port wire function
to either 2-wire or 4-wire (ON:485 2-wire, OFF: 422/485
4-wrie). Default is OFF.
DIP 4 (TMR) Enable/Disable RS-422/485 terminator.
Default is OFF (Disable).
