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 converter s 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
Ohm 150K 10K 4.7K 3.3K 1K 909 822 770 500 485

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.

ATTENTION

Electrostatic Discharge Warning!

To protect the product from damage due to electrostatic
discharge, we recommend wearing a grounding device when
handling your ICF-1150 series.

Mounting

The aluminum DIN-Rail attachment plate should be fixed to the back panel of
the ICF-1150 when you take it out of the box. If you need to reattach the
DIN-Rail attachment plate to the ICF-1150, make sure the stiff metal spring is
situated towards the top, as shown in the figures below.

STEP 1:

Insert the top of the DIN-Rail into the slot just below the stiff metal spring.

STEP 2:

The DIN-Rail attachment unit will snap into place as shown below.
