Introduction

The TCF-142 Series converter 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. TCF-142 converters are used to extend serial transmission distance up to 2 km (TCF-142-M multi-mode fiber) or up to 20 km (TCF-142-S single-mode fiber). Note that the RS-232 and RS-422/485 interfaces cannot be used on the same TCF-142 at the same time to convert to fiber.

Why Convert Serial to Fiber?

Fiber communications not only extends the communication distance, but is also beneficial in many other ways, such as:

  • Immunity from electrical interference
    Optical fiber is not effected by electromagnetic interference or radio frequency interference, provides a clean communication path, and is immune from cross-talk.
  • Insulation
    Optical fiber is an insulator; the glass fiber eliminates the need for using an electric current as the data transmission medium.
  • Security
    Optical fiber cannot be tapped by conventional electronic means, and is very difficult to tap into optically. Furthermore, radio and satellite communication signals can be easily captured for decoding.
  • Reliability and Maintenance
    Optical fiber is immune from adverse temperature and moisture conditions, does not corrode or lose its signal, and is not affected by short circuits, power surges, or static electricity.

DIP Switch Selectable Terminator

For many products of this type, the termination resistor is set by a jumper located inside the product's casing, so that the user must open the casing to disable or change the resistor's strength. Moxa offers a better solution. TCF-142's terminator is set with a DIP Switch located on the outside of the converter's casing.

Auto Baud Rate Detection

TCF-142 incorporates a method for automatically detecting the serial signal's baud rate by hardware. This is an extremely convenient feature for the user. Even if a device's baud rate changes, the signal will still be transmitted through the converter without any problem.

Ring Operation

To allow one serial device to communicate with multiple devices connected to a fiber ring, you should configure 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 to form 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.

NOTE: Only TCF-142-M v2.1 and TCF-142-S v2.3 (and later versions) support ring mode.

Automatic Data Direction Control (ADDC™)

ADDC™ is a MOXA leading technology that uses a clever hardware solution to take care of the RS-485 data direction control problem. The TCF-142 Series converter uses embedded ADDC™ technology, a hardware data flow solution, to automatically sense and control data direction, making the hand shaking signal method unnecessary.

Manufacturer Warranty Policy

MOXA

Moxa products are warranted to be free from manufacturing defects in materials and workmanship starting from the date of delivery. The actual warranty period of the product(s) depends on the product category.

Warranty Periods

* The 3-year warranty period for Embedded x86 Box Computers is effective for products shipped after Jan. 1, 2010. A 5-year warranty still applies to products shipped before 2010.

* For products containing storage devices (hard drives, flash drives, etc.), back up your data before sending the products for repair. Moxa is not responsible for any loss of data. Please ensure the use of properly licensed software with our systems. Moxa does not condone the use of pirated software and will not service systems using such software. Moxa will not be held legally responsible for products shipped with unlicensed software installed by the user.

* If the customer opens the computer to install an HDD without making any modifications to the unit, the warranty will remain valid.

Product warranties remain valid provided the product was properly installed and used. Defects, malfunctions, or failures of the warranted product caused by damage resulting from acts of God (such as floods, fire, etc.), environmental and atmospheric disturbances, other external forces such as power line disturbances, host computer malfunction, plugging the board in under power, or incorrect cabling, and damage caused by misuse, abuse, and unauthorized alteration or repair, are not warranted. A product will not be warranted in the following situations:

This warranty is limited to the repair and/or replacement, at Moxa's sole discretion, of the defective product during its warranty period. Moxa will replace any product found to be defective within the first three months of purchase provided said product was properly installed and used. The customer must obtain a Return Merchandise Authorization (RMA) number prior to returning the defective product to Moxa for service.

The customer agrees to insure the product or assume the risk of loss or damage during transit, to prepay shipping charges, and to use the original shipping container or equivalent. Customers may either seek assistance from the original dealer, or from the closest Moxa Service Office. Repaired or replaced products are warranted for ninety (90) days from the date of repair or replacement, or for the remainder of the original product's warranty period, whichever is longer. For large order projects, customers may purchase an extended maintenance contract. Such products may have a shorter chipset life cycle, or some parts may have a limited warranty from the original supplier of the parts. Please contact Moxa's sales department if you would like to extend the maintenance period of a Moxa product.

Limitation of Liability

The provisions of the warranty are in lieu of any other warranty, whether expressed or implied, written or oral. Moxa's liability arising out of the manufacture, sale, or supplying of the product and its use, whether based on warranty, contract, negligence, product liability, or otherwise, shall not exceed the original cost of the product. In no event shall Moxa be liable for unintended or consequential damages, including, but not limited to, a loss of profits or use damages arising out of the manufacture, sale, or supplying of the product.
