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.
