ICF-1150-M-SC: RS-232/422/485 serial-to-fiber optic SC multi-mode converter

ICF-1150 serial-to-fiber converters transfer RS-232 / RS-422 / RS-485 signals to fiber optic ports to improve transmission distance. When an ICF-1150 device receives data from any serial port, it sends the data through the fiber optic ports. These products not only support single-mode and multi-mode fiber for different transmission distances, but models with isolation protection are also available to improve noise immunity. ICF-1150 products feature three-way communication and a rotary switch for setting high/low pull resistance for on-site installation.

## Three-Way Communication

The ICF-1150 series supports 2 serial ports, with a DB9 connector for RS-232 communication and a removable terminal block for RS-422 or RS-485 communication. The 3 ports (2 serial ports and one fiber port) are completely independent. When an ICF-1150 converter receives data from any port, it will send the data through the other 2 ports. For example, once the ICF-1150 converter receives a command from the remote master through the fiber port, it will convert the signal and send the command through the RS-232 and RS-422/485 ports simultaneously. If the user is monitoring a system running on an RS-485 network, it is not necessary 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 High/Low Pull Resistance Setting

The RS-485 interface supports multidrop or daisy-chain connections, which system technicians will use to connect serial devices such as meters, RTUs, and readers, together on the same bus. Since the number of serial devices on the same bus will increase the impedance of the data line, the ICF-1150 allows users to adjust the high/low pull resistance. Simply rotate the switch to the appropriate value without removing the ICF-1150 from the DIN rail.

## FEATURES

- 3-way communication: RS-232, RS-422/485, and fiber
- Rotary switch for changing high/low pull resistance value
- Extends RS-232/422/485 transmission up to 5 km with multimode
- Models available for a wide temperature range from -40 to 85 ° C
- C1D2, ATEX, and IECEx certification for harsh industrial environments
