MOXA TCF-142-RM Series TCF-142-M-SC-RM Serial to Fiber Converters
Technical Support Contact Information www.moxa.com/support
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.

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 converter glow
continuously, remove the fiber cable and reconnect.
NOTE: Ring Mode” can only be used for half-duplex applications.
The settings for the RS-485 DIP switches are:
S2 | Pin1 | Pin 2 | Pin 3 |
---|---|---|---|
RS-232 | ON | ON | – |
RS-422 | ON | OFF | – |
RS-485 (4W) | OFF | OFF | – |
RS-485 (2W) | OFF | ON | – |
Ring | – | – | ON |
Point to Point | – | – | OFF |
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.
RS-485 Data Direction Control Settings
RS-485 Data Direction Control | S3 Pin 1 |
---|---|
Auto Baudrate | OFF |
Fixed Baudrate | ON |
Data Format Settings
Data Format | S3 Pin 2 | S3 Pin 3 | S3 Pin 4 |

7 Bits | OFF | ON | ON |
8 Bits | ON | OFF | ON |
9 Bits | OFF | OFF | ON |
10 Bits | ON | ON | OFF |
11 Bits | OFF | ON | OFF |
12 Bits | ON | OFF | OFF |
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.
