Overview
Introduction
ICF-1150 series fiber converters have 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 advantageous 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 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
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 of the RX
ports.

Rotary Switch for Setting the Pull High/Low 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 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.)

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.

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.
To remove the ICF-1150 series from the DIN rail, simply reverse Steps 1
and 2 above.
