Overview
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 multi-mode
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.
Users should
ensure that the total fiber ring
length is less than 100 km
when
using
either single-mode
models
(
TCF-142-S) or multi-mode
m
odels (TCF-142-M).

ATTENTION
For Fiber Ring Users:
To avoid problems when setting up a fiber ring, each 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
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).
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.

•Protect against electronic degradation and chemical corrosion
•Supports baudrates up to 921.6 kbps
•Extended operating temperature from -40 to 75°C (for “T” models)
Package Checklist
Before installing the TCF-142, verify that the package contains the
following items:
•1 TCF-142 media converter

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 wearing a grounding device when
handling your TCF-142.

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.

The S1 DIP Switch is located inside the TCF-142. When the TCF-142 is in
RS-485 mode, use this DIP switch to configure RS-485 data direction
control, data format, and baudrate. When the TCF-142 is in RS-232/422
mode, the S1 DIP switch cannot affect RS-232/422 communication.
