ICF-1150I-M-ST-IEX - Industrial RS-232422485 to multimode fibre optic converter

Introduction
The ICF-1150 serial-to-fibre converters transfer RS-232/RS-422/RS-485 signals to fibre optic ports to increase the transmission range. When an ICF-1150 device receives data from any serial port, it transmits the data via the fibre optic ports. These products not only support singlemode and multimode fibres for different transmission distances, but models with isolation protection are also available to increase interference immunity. The ICF-1150 products feature three-way communication and a rotary switch to adjust the pull high/low resistance for field installation.

Three-way communication
The ICF-1150 series supports 2 serial ports with a DB9 connector for RS-232 communication and a detachable terminal block for RS-422 or RS-485 communication. The 3 ports (2 serial ports and one fibre optic port) are completely independent of each other. When an ICF-1150 converter receives data from one of the ports, it sends the data via the other 2 ports. For example, when the ICF-1150 converter receives a command from the remote master via the fibre optic port, it converts the signal and sends the command via the RS-232 and RS-422/485 ports simultaneously. If the user is monitoring a system running on an RS-485 network, there is no need to use an additional RS-232 to RS-485 converter to connect the laptop's serial port to the RS-485 bus.

Rotary switch for setting the pull high/low resistance
The RS-485 interface supports multidrop or daisy chain connections, which are used by system engineers to connect serial devices such as counters, RTUs and readers together to the same bus. As the number of serial devices on the same bus increases the impedance of the data line, the ICF-1150 allows you to set the pull high/low resistance. Simply turn the switch to the appropriate value without removing the ICF-1150 from the DIN rail.
