TCF-142 Quick Installation Guide
Thirteenth Edition, January 2015
Overview
Introduction
TCF-142 series converters are equipped wit h a multip le interf ace circuit that can handle RS-232, RS-422, and RS-485 serial inter faces, as well as multi-mod e or sin gle-mode f iber. TCF-142 converters are used to extend serial transmission distance up to 5 km (TCF-142-M, with multi-mode f iber) or up to 40 km (TCF-142-S, wit h 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 advantage ous features.
IMMUNITY FROM ELECTRICAL INTERFERENCE: Fib er is not affected by electromagnetic interference or radio frequency interference. It provides a clean communication path and is immune to cross-talk.
INSULATION: Opti cal fiber is an insu lator; the glass fibe r eliminates the need for using electric curren ts as the communication medium.
SECURITY: Fiber cannot be tappe d by conventional electric means and is very difficult to tap into optically.
RELIABILITY & MAINTENANCE: Fiber is im mune to a dverse temperature and moisture conditions, does not corrode or lose its signal, and is not a ffected by short c ircuits, power surges, or stat ic electric ity.
Reverse Power Protection
The Reverse Power Protection feature provides extra protection against accidentally connecting the po wer cables to the wron g terminal. The converter automatically detects which power wire is positive and which is negative.
Ring Mode
To allow one half-dup lex seria l device t o commu nicate w ith mu ltiple half-dup lex devices connected t o a fiber ring, you sh ould configure the TCF-142 for “ring mode” by settin g DIP switch “SW4” to the “On” position. The Tx port of a partic ular 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.
Users
should ensure that the total fiber ring length is less than 100 km
when using either
s
ingle-mode models
(
TCF-142-S) or multi -mode
m
odels (TCF-142-M).
ATTENTION
For Fiber Ring Users:
To avoid problem s when se tting u p a fiber ring, e ach TCF-142 unit making up the ring must be powered down and set to “Ring mode.” Next, make sure all cables are connected properly, and the n pow
er up all devices
connected to the ring.
NOTE
“Ring Mode” can only be used with half-duplex ap plicat ions (i.e., RS-485 multi-drop communication ).
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 compat ible wit h 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.

Dimensions and Appearance
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).
NOTE Electrostatic Discharge Warning!
To protect the product from damage due to electrostatic discharge, we recommend we aring a grounding dev ice when handling your TCF-142.
