5. Wiring Examples
Hot-Swappability TCF-142-S and TCF-142-M are hot-swappable. You may plug and un-plug the signal cables and wires when the converter is under power.
Connecting the Power Supply Before using the TCF-142, you need to connect the power supply. To do so, connect the power supply to the power supply terminal block located on the bottom side of TCF-142. TCF-142 uses a DC power supply.
Electrostatic Discharge Warning! To protect the product from damage due to electrostatic discharge, we recommend wearing a grounding device when maintaining TCF-142.

DIP Switch Selectable Terminator For many products of this type, the termination resistor is set by a jumper located inside the product’s casing, so that the user must open the casing to disable or change the resistor’s strength. MOXA offers a better solution, since TCF-142’s termination resistor is set with a DIP Switch located on the outside of the converter’s casing.

4. Dimensions and Appearance TCF-142 fiber converters are easy to set up and use. In general, you must purchase two TCF-142 converters. The serial terminal block of one of the converters connects to your computer, and the serial terminal block of the other converter connects to your serial device.

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.
Before installing TCF-142, verify that the package contains the following items: ! TCF-142-S or TCF-142-M Fiber Converter ! Quick Installation Guide ! 7-contact terminal block connector ! 3-contact terminal block connector Notify your sales representative if any of the above items is missing or damaged

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 onto 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.

Introduction TCF-142 series converters are equipped with a multiple interface circuit that can handle RS-232, or RS-422/485 serial interfaces, and multi-mode or single-mode fiber. TCF-142 converters are used to extend serial transmission distance up to 2 km (TCF-142-M, with multi-mode fiber) or up to 20 km (TCF-142-S, with single-mode fiber). TCF-142 must be configured to transmit a particular serial interface. I.e., you cannot transmit both RS-232 and RS-485 signals at the same time.

Auto Baud Rate Detection TCF-142 incorporates a method for automatically detecting the serial signal’s baud rate by hardware. This is an extremely convenient feature for the user. Even if a device’s baud rate changes, the signal will still be transmitted through the converter without problem.
