Overview
Introduction
The TCF-142-RM series fiber converters are slide-in modules that can
be installed in the NRack System’s rackmount chassis, such as the TRC-
190 series. The slide-in module is equipped with a multiple interface
circuit that can handle RS-232 or RS-422/485 serial interfaces, and
multi-mode or single-mode fiber. The TCF-142-RM series slide-in
modules are used to extend serial transmission distance up to 5 km
(TCF-142-M-XX-RM, with multi-mode fiber) or up to 40 km (TCF-142-S-
XX-RM, with single-mode fiber).
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. 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.
No Configuration Required for Baudrate Settings
The TCF-142-RM slide-in modules work under any baudrate from 50
bps to 921.6 Kbps. The TCF-142-RM slide-in modules simply convert
the signal back and forth between serial (RS-232, RS-422, or RS-485)
and fiber, and since the TCF-142-RM slide-in modules do not need to
interpret the signal, it does not need to know the baudrate of the
transmitting device. For this reason, the TCF-142-RM slide-in modules
do not have any DIP switches or jumpers for setting the baudrate.
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-RM slide-in modules for “ring mode” by setting DIP switch
“SW3” to the “On” position. The Tx port of a particular TCF-142-RM
slide-in modules unit connects to the neighboring converter’s Rx port to
form the ring. Note that when one node transmits a signal, the signal
travels around the ring until it returns 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 or
multi-mode models.

Installation
The media converter slide-in module can be hot-swapped, which means
the chassis doesn’t have to power off or be removed during installation.
Align the slide-in module with the chassis installation slot so that the
panel fastener screw is at the top of the module. Carefully slide the
slide-in module into the slot while aligning the module’s circuit board
with the installation guide. Ensure the slide-in module is firmly seated
inside the chassis. Push in and rotate the attached panel fastener screw
clockwise to secure the module to the chassis.

Switch Settings
There are three sets of DIP switches on the board. One set for fiber and
another for the connector. Following are the settings for the three
connector DIP switches.

ATTENTION
For Fiber Ring Users:
Before you plug the slide
-
in module into the chassis, make sure
the DIP switch settings are correct before inserting the slide
-in
module into the chassis and connecting the serial and fiber
cables. If the Rx LEDs of the conv
erter glow continuously,
remove the fiber cable and reconnect.
NOTE
“Ring Mode” can only be used for half-duplex applications.

The S3 DIP Switch is located inside the TCF-142-RM. When the TCF-
142-RM is in RS-485 mode, use this DIP switch to configure RS-485
data direction control, data format, and baudrate. When the TCF-142-
RM is in RS-232/422 mode, the S3 DIP switch cannot affect RS-
232/422 communication.

The serial data format includes one start bit, between five and eight
data bits, and one stop bit. A parity bit and an additional stop bit might
be included in the format as well.
For example, 8-N-1 is interpreted as eight data bits, no parity bit, and
one stop bit. Users need to adjust the DIP switch to set the data format
to 10 bits.
