Introduction

The TCF-90 is a compact media converter that transmits RS-232 signals over optical fiber. Power is derived from either the serial port or an

external power source. The TCF-90 extends RS-232 transmission up to 5 km with multi-mode fiber, or up to 40 km with single-mode fiber. A pair of

TCF-90 converters can be used to connect two RS-232 devices with optical fiber in full-duplex mode. The optical fiber isolates the data signals

from dangerous increases in ground potential, ground loops, and electrical EMI/RFI noise, and it enhances data security by eliminating the harmful

effects of RF radiation and susceptibility to electromagnetic radiation.

Self-Powered RS-232 to Optical Fiber

Connecting RS-232 devices to the TCF-90 is easy. The ST-type

optical-fiber connector is designed especially for data

communication applications that transmit data either between or

within buildings. The TCF-90 can be used for industrial applications

and for applications that require secure data transfer.

The RS-232 port on the TCF-90 uses a DB9 female socket to connect

directly to the host PC, with power drawn from the TxD, RTS, and

DTR lines. Although the TCF-90 can obtain enough power from the

three data/handshake lines, whether the signal is high or low, we

strongly recommend setting either the RTS or DTR signal to ON.

LED Port Power Indicator

It’s easy enough to use a multimeter to test if the serial device is

supplying the TCF-90 with enough power through the serial

connection, but the TCF-90 can do the testing for you. Connect the

TCF-90 to the device’s RS-232 port and set the SW4 switch to Test

mode. If the port power LED indicator lights up, the TCF-90 is

receiving enough power. If the LED does NOT light up, you will need

to attach an external power source to the TCF-90.

Optional External Power Source

In most circumstances, the TCF-90 should be able to operate without using an external power source. However, an external USB power cord or DC

power supply can be used in situations where the handshake lines are not available, both the RTS/DTR signals are set to OFF, or the attached

device’s serial interface chip provides less power than required.
