## Long description

The Moxa TCF-142-S-SC-RM is a professional-grade serial-to-fiber converter and repeater designed specifically for integration into the NRack System. This slide-in module facilitates seamless communication between RS-232, RS-422, or RS-485 serial interfaces and fiber optic networks. By converting serial signals into optical signals, it enables reliable data transmission over extended distances, ensuring robust connectivity in demanding industrial environments.
Advantages
This converter offers exceptional versatility by supporting multiple serial standards within a single compact module. Its design allows for significant extension of signal range, reaching up to 40 kilometers over single-mode fiber, which is essential for large-scale industrial infrastructure. The inclusion of adjustable pull high/low resistors provides flexibility for various network configurations, while the support for both point-to-point and ring topologies ensures high adaptability for diverse communication requirements.
Suitable for
Industrial automation and control systems
Long-distance serial data communication
Integration into existing NRack chassis environments
Point-to-point and ring network topologies
This device may not be suitable for applications requiring non-serial data transmission or environments where fiber optic infrastructure is not available. It is specifically designed for use with the TRC-190 rack system and may not function as a standalone unit without the appropriate chassis.
Key specifications
Supported interfaces: RS-232, RS-422, RS-485
Fiber connector type: SC
Transmission distance: Up to 40 km (single-mode)
Resistor settings: 1K or 150K ohm adjustable pull high/low
Housing: Durable SPCC material
Input voltage: 12V
To use the Moxa TCF-142-S-SC-RM, insert the module into a compatible TRC-190 rack chassis. Connect your serial device to the appropriate port and link the fiber optic cable to the SC connector. Configure the pull high/low resistors as required by your specific network setup to ensure signal integrity. Once installed, the device automatically handles the conversion process between the serial and fiber signals.
What to consider before purchase
Ensure compatibility with your existing TRC-190 rack system
Verify that your network infrastructure utilizes SC fiber optic connectors
Confirm the required transmission distance matches the single-mode fiber capabilities
Usage recommendations: Always ensure that the fiber optic cables are clean and properly seated in the SC connectors to maintain optimal signal quality. Periodically check the rack chassis power supply to ensure consistent 12V input for reliable operation.
