The Moxa ICF-1150-M-SC is an industrial media converter that converts serial signals of the RS-232, RS-422, and RS-485 standards into 100BaseFX transmission over multi-mode fiber optic cable (SC connector). The device is used to connect serial devices to fiber optic networks, particularly in industrial applications where high EMC immunity, galvanic isolation, and robust operating conditions are required. The integrated 2-kV isolation protects against electrical interference and enables secure communication in noisy environments.

Applications
This converter is designed for use in industrial networks, particularly in manufacturing automation, power supply, transportation, and building automation systems. It is suitable for extending serial connections over longer distances via fiber optic cable, with galvanic isolation preventing electrical interference and potential differences between devices. DIN rail mounting and a wide voltage range of 12 to 48 VDC allow flexible integration into existing systems.

Functions and Features in Detail
The device features two serial ports connected via a 5-pin terminal block. Support for RS-232, RS-422, and RS-485 (in 2- and 4-wire technology) enables connection to various devices. The baud rate can be set between 50 bps and 921.6 kbps, including non-standard values. For RS-485 communication, an automatic data direction control (ADDC) is integrated, enabling data transmission without an additional control line. Configuration options for pull-up and pull-down resistors in various values (e.g. 150 kΩ, 10 kΩ, 4.7 kΩ, 3.3 kΩ, 1 kΩ, 909 Ω, 822 Ω, 770 Ω, 500 Ω, 485 Ω) and selection of termination resistors (N/A, 120 Ω, 120 kΩ) allow application-specific interface adaptation.

Technology Explained Simply
The converter transforms serial data into a fiber optic format transmitted over 100BaseFX networks. The use of multi-mode fiber with SC connector enables reliable data transmission over long distances. Galvanic isolation at 2 kV protects against voltage spikes and potential differences, which is especially important in industrial environments. Power supply is via a terminal block in the range of 12 to 48 VDC, with integrated overcurrent and reverse polarity protection. Maximum current consumption is 300 mA.

Compatibility and Accessories
The converter is designed for use in industrial networks with fiber optic infrastructure. Connection is made via SC connectors on multi-mode fiber cables. The serial interface is compatible with devices supporting RS-232, RS-422, or RS-485. Signal assignment is standardized: RS-232 (TxD, RxD, GND), RS-422 (Tx+/-, Rx+/-, GND), RS-485-4w (Tx+/-, Rx+/-, GND), RS-485-2w (Data+/-, GND). Configuration options for pull-up/down resistors and termination resistors allow adaptation to different network topologies.
