Overview
Users should ensure that the total fiber ring length is less than 100 km s S 142
Introduction
TCF-142 series converters are equipped with a multiple interface circuit that can handle RS-232, RS-422, and RS-485 serial interfaces, as well as multi-mode or single-mode fiber. TCF-142 converters are used to extend serial transmission distance up to 5 km (TCF-142-M, with multi­mode fiber) or up to 40 km (TCF-142-S, with single-mode fiber). The TCF-142 must be configured to transmit a particular serial interface. You cannot transmit both RS-232 and RS-485 signals at the same time.
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 into optically.
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.
Reverse Power Protection
The Reverse Power Protection feature provides extra protection against accidentally connecting the power cables to the wrong terminal. The converter automatically detects which power wire is positive and which is negative.
Ring Mode
To allow one half-duplex serial device to communicate with multiple half-duplex devices connected to a fiber ring, you should configure the TCF-142 for “ring mode” by setting DIP switch “SW4” to the “On” position. The Tx port of a particular TCF-142 unit connects to the neighboring converter’s Rx port on the ring. Note that when one node transmits a signal, the signal travels around the ring until it returns back to the transmitting unit, which then blocks the signal.

-M).

ATTENTION
For Fiber Ring Users:
To avoid problems when setting up a fiber ring, each TCF unit making up the ring must be powered down and set to “Ring mode.” properly, and then power up all devices connected to the ring.
NOTE
“Ring Mode” can only be used with half-duplex applications (i.e., RS-485 multi-drop communication).
Next, make sure all cables are connected
DIP Switch Selectable Terminator
The TCF-142’s termination resistor is set with a DIP switch located on the outside of the converter’s casing.
No Configuration Required for Baudrate Settings
The TCF-142 is compatible with any baudrate from 50 bps to 921.6 kbps. The TCF-142 automatically converts the signal back and forth between serial (RS-232, RS-422, or RS-485) and fiber, and does not need to interpret the signal or the baudrate of the transmitting device. For this reason, the TCF-142 does not have any DIP switches or jumpers for setting the baudrate.

NOTE
Electrostatic Discharge Warning!
To protect the product from damage due to electrostatic discharge, we recommend wearing a grounding device when handling your TCF-142.

TCF-142 fiber converters are easy to set up and use. The serial terminal block of one of the converters connects to your computer, the serial terminal block of the other converter connects to your serial device, and the two converters are connected by fiber cable(s).
Wiring Examples
Connecting the Power Supply
Before using the TCF-142, first connect the DC power supply to the power supply terminal block located on the TCF-142’s bottom panel.
