1. Introduction
The converter is designed to provide the most versatile connection possible between two RS-232 serial equipment using fiber optic cable. It
allows any two pieces of serial equipment to communicate full-duplex
over typical duplex fibers,or over optional single fiber up to 20km. The
converter supports transparent conversion for not only RS-232 data lines,
but also all RS-232 control signals. It also supports all RS-232 baud rates
with no need for user configuration. The Din-rail mountable design makes
it ideal for industrial cabinets and enclosures.

For industrial environment, the converters are designed with the following enhanced features exceeding that of commercial media converters:• High and wide operating Temperature• Wide operating voltage range for DC power input• Power input interface: Industrial screw terminal block and DC
power jack for external commercial power adapter as option• DIN rail mounting support for industrial enclosure• Screw panel mounting support for industrial enclosure• Industrial-rated Emission and Immunity performance-5-1.1 Featuresz Transparent conversion for all RS-232 signals

2.2 Safety Cautions
To reduce the risk of bodily injury, electrical shock, fire, and damage tothe equipment, observe the following precautions.
• Do not service any product except as explained in your system
documentation.

• Opening or removing covers may expose you to electrical shock.
Only a trained service technician should service components insidethese compartments.

• If any of the following conditions occur, unplug the product from theelectrical outlet and replace the part or contact your trained service
provider:- The power cable, extension cable, or plug is damaged.
- An object has fallen into the product.
- The product has been exposed to water.
- The product has been dropped or damaged.
- The product does not operate correctly when you follow theoperating instructions.
• Do not push any objects into the openings of your system. Doingso can cause fire or electric shock by shorting out interior components.
• Operate the product only from the type of external power source
indicated on the electrical ratings label. If you are not sure of thetype of power source required, consult your service provider or local
power company.

Power Consumption Max. 2.4W @30VDC
The device provides two types of power interfaces, terminal block and DCpower jack for receiving DC power input from external power supply.

Using Terminal Blocks
Either DC1 interface or DC2 interface can be used to receive DC powerfrom an external power system. Or, DC2 also can be used to deliver thepower received on DC1 to next device in cascading way.
DC1 +Vdc Positive (+) terminal

DC1 -Vdc Negative (-) terminal

DC2 +Vdc Positive (+) terminal

DC2 -Vdc Negative (-) terminal

Three 2P terminal plugs are provided together with the device. Two of thethree plugs are used for DC1 and DC2 interfaces respectively. The plug isshown below:-17-Power wires: 24 ~ 12AWG (IEC 0.5~2.5mm2)
Install the power source wires with the plug properly. Screw the wire withplug securely. Then, plug in DC1 contacts.

If cascading the power to next device is needed, install the power wires
and plug for another switch. Then, use DC2 contacts.
Note: Only up to four device units can be cascaded to receive powerfrom one main power input source.

Using DC Power Jack
DC Jack Connector: Jack D 6.3mm
D 2.0mm
AC Power Adapters: Optional commercial rated adapters are available
for purchasing.

Rated AC120V/60Hz DC7.5V 1A
Rated AC230V/50Hz DC7.5V 1A
Rated AC100V/50-60Hz DC7.5V 1A
Rated AC240V/50Hz DC7.5V 1A
Connect power adapter DC plug to the DC power jack of the converter
before connecting to the AC outlet. Connect the power adapter to theAC outlet.

Note: Before you begin the installation, check the AC voltage of yourarea. The AC power adapter which is used to supply the DC power
for the unit should have the AC voltage matching the commercialpower voltage in your area.

-19-2.6 Power Failure Relay Output
The device provides a relay output to report power failure event to aremote alarm monitoring system. The replay output is provided with twocontacts labeled PF+ and PF- in the terminal block interface.

Use the provided 2P terminal plug for signal wiring and plug into the PF+/
- contacts. The function is designed as :Power is normal PF+ contact is shorted with PF- contact.
Power failure
PF+ contact is disconnected with PF- contact.
Note: Be sure the voltage applied on PF+/- contacts is within thespecification of 30VDC/1A max. or 120VAC/0.5A max.

2.9 Application
The converter can be used to extend the distance between two serial
devices via fiber cables. The distance can be 2km, 20km, and even up to100km.
The following example illustrates a PC performs serial communocation
with another RS-232 device far apart:The converter converts all signals of the COM port of the PC to opticalsignals and sends to the other converter far apart over fiber cable.
