Overview
Introduction
The ICF-1150 series of fiber converters has a multi-interface circuit that
can handle RS-232 and RS-422/485 serial interfaces, as well as multi-
mode or single-mode fiber. ICF-1150 series converters 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 helpful features.
IMMUNITY FROM ELECTRICAL INTERFERENCE: Fiber is not affected by
electromagnetic interference and 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 communications medium.
SECURITY: Fiber cannot be tapped by conventional electronic 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 detects automatically which power wire is positive and which
is negative, and then adjusts 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
The ICF
-1150 is designed to receive data from one port and
send data to the other ports. If the ICF
-1150 receives data
from 2 ports at the same time, a data error
may occur on all
the RX ports.
Rotary Switch for Setting the Pull Up/Down Resistor
Since the RS
-485 port can support multi-drop
connections or daisy
-
chain connections, system
engineers can connect meters, RTUs, readers,
and many other devices together on the same
bus. The impedance of t
he 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
up
/down 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.)

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.
NOTE
The ICF-1150I default setting is auto baudrate. If you need to
use the
fixed baudrate,
then you will need to use the DIP switch
to do the configuration.
Ring Mode
To allow one half-duplex serial device to communicate with multiple
half-duplex devices connected to a fiber ring, 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 to

- 4 -
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 product.
Mounting (in an enclosure or industrial panel)
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.
To remove the ICF-1150 series from the DIN rail, simply reverse Steps
1 and 2 above.

For Fiber Ring Users:
If the Rx LEDs of the converter glow continuously, remove the
fiber cable
and then reconnect. The Rx LEDs should no longer
glow
continuously.
NOTE
: “Ring Mode” can only be used for half-duplex
applications.
The S3 DIP Switch is located inside the ICF-1150. When the ICF-1150
is in RS-485 mode, use this DIP switch to configure RS-485 data
direction control, data format, and baudrate. When the ICF-1150 is in
RS-232/422 mode, the S3 DIP switch cannot affect RS-232/422
communication.
Direction Control and Data Format Setting
You will need to open the product's casing to do the Direction Control
and Data Format Setting.

The serial data format includes one start bit, between five and eight
data bits, and one stop bit. A parity bit and an additional stop bit might
be included in the format as well.
For example, 8-N-1 is interpreted as eight data bits, with no parity bit,
and one stop bit. Users need to adjust the DIP switch to set the data
format to 10 bits.
