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.
