Caution
Circuit devices are sensitive to static electricity, which can damage their delicate
electronics. Dry weather conditions or walking across a carpeted floor may cause you to
acquire a static electrical charge.
To protect your device, always:
• Touch the metal chassis of your computer to ground the static electrical charge
before you pick up the circuit device.
• Pick up the device by holding it on the left and right edges only.

1. Introduction
1-1. Overview of fiber converter
The fiber optic converter of RS232/422/485 to Fiber Optic is used to
extend the distance up to 2Km over the multi-mode fiber or up to 20Km
over single-mode fiber. The converter is equipped with multiple interface
circuit such as RS232, RS422, RS485 2/4-wire.
Note: This product has to be used in pairs
1-2. Checklist
Before you start installing the Converter, verify that the package contains
the following:

2. Installation
2-1. Installing the Fiber converter
Mounting on DIN-Rail
⇒ Remove the four screws on the both sides of the converter.
⇒ Place the converter on the mounting bracket.
⇒ Align the screw holes on the bracket with the holes on the both sides of
the converter. (See Fig. 3)
⇒ Insert the 2 x 5mm screws and tighten them until they are secure.
Fig. 3
⇒ Position the fixed DIN-rail clip on the backside of the bracket on to the
DIN-rail.
⇒ Pull up the moveable DIN-rail clip to attach the bracket to the DIN-rail,
and then release the clip.
(See Fig. 4)
⇒ Make sure the converter is securely mounted on the DIN-rail.
