Overview

Introduction

The ICF-1150 series fiber converters are equipped with a multiple interface

circuit that can handle RS-232 and RS-422/485 serial interfaces, as well as

multi-mode or single-mode fiber. The ICF-1150 series converters are used to

extend serial transmission distance up to 5 km (ICF-1150-M, with multi-mode

fiber) or up to 40 km (ICF-1150-S, with single-mode fiber).

Why Convert Serial to Fiber?

Fiber communication not only extends the communication distance, but also

provides many advantageous features. IMMUNITY FROM ELECTRICAL

INTERFERENCE: Fiber is not affected by electromagnetic interference or

radio frequency interference. It provides a clean communication path and is

immune to cross-talk. INSULATION: Optical fiber is an insulator; the glass

fiber eliminates the need for using electric currents as the communication

medium. SECURITY: Fiber cannot be tapped by conventional electric means

and is very difficult to tap into optically. Furthermore, radio and satellite

communication signals can be captured easily for decoding. RELIABILITY &

MAINTENANCE: Fiber is immune to adverse temperature and moisture

conditions, does not corrode or lose its signal, and is not affected by short

circuits, power surges, or static electricity.

Reverse Power Protection

The Reverse Power Protection feature provides extra protection against

accidentally connecting the power cables to the wrong terminal. The converter

is designed to detect automatically which power wire is positive and which is

negative, and then adjust the power supply accordingly.

3-Way Communication

The ICF-1150 series supports 2 serial ports. The D-sub connector is for RS-232

communication and the removable terminal block is for RS-422 or RS-485

communication. The 3 ports (2 serial ports and one fiber port) are completely

independent. When the ICF-1150 series converters receive data from any port,

it will send data out through the other 2 ports. For example, when the ICF-1150

series converters receive a command from the remote Master via the fiber port,

it will convert the command and transmit it via the RS-232 port and

RS-422/485 port at the same time. So if the user is trying to monitor a system

running on the RS-485 network, there is no need to use an additional RS-232 to

RS-485 converter to connect the laptop computer’s serial port to the RS-485

bus.

ATTENTION

ICF-1150 is designed to receive data from one port and send

data to the other ports.

If ICF-1150 receive data from 2 ports at the same time, that

may cause the data error on all the RX ports.

Rotary Switch for Pull High/Low Resistor Setting

Since the RS-485 port can support multi-drop connection or daisy-chain

connection, system engineers can connect meters, RTUs, readers, or many

other devices together on the same bus. The impedance of the data line will rise

according to the number of serial devices on the same bus. To get the system

working, the ICF-1150 has a setting for tuning the pull high/low resistor. Just

turn the dial to find the best resistor value for the system without removing the

ICF-1150 from the DIN-rail. (The default settings are 1K for both switches.)

Pull High/Low Resistor

Position 0 1 2 3 4 5 6 7 8 9

DIP Switch for Selectable Terminator

The termination resistor for many products of this type is set by a jumper

located inside the product’s casing. To disable or change the resistor’s strength,

the user must open the casing to reset the jumper. Moxa offers a more

user-friendly solution that allows users to set the termination resistor with a

DIP switch located outside the ICF-1150 converter’s casing.

No Conﬁguration Required for Baudrate Settings

The ICF-1150 works under any baudrate from 50 bps to 921.6 Kbps. The

ICF-1150 simply converts the signal back and forth between serial (RS-232,

RS-422, or RS-485) and fiber. Since the ICF-1150 does not need to interpret

the signal, it does not need to know the baudrate of the transmitting device. For

this reason, the ICF-1150 does not have any DIP switches or jumpers for

setting the baudrate.

Ring Mode

To allow one half-duplex serial device to communicate with multiple

half-duplex devices connected to a fiber ring, you should configure the

ICF-1150 for “ring mode” by setting DIP switch “SW3” to the “On” position.

The Tx port of a particular ICF-1150 unit connects to the neighboring

converter’s Rx port to form the ring. Note that when one node transmits a

signal, the signal travels around the ring until it returns back to the transmitting

unit, which then blocks the signal. Users should ensure that the total fiber ring

length is less than 100 km when using either single-mode models or

multi-mode models.
