Introducing
The TCF-90 is a compact sized, high-speed, RS-232 to optical fiber converter that extends RS-232 transmission from 15 meters to 5 km (TCF-90-M, multi-mode) or 40 km (TCF-90-S, single-mode), without using external power. The TCF-90 is designed to get power from the attached serial port. A pair of TCF-90 converters can be used to connect two RS-232 serial devices to each other in full duplex transmission mode using optical fiber. Moreover, the TCF-90 isolates the devices from dangerous increases in
ground potential, ground loops, and electrical EMI/RFI noise. This greatly reduces RF radiation and susceptibility to electromagnetic radiation to enhance data security.
Port-powered RS-232 to Optical Fiber Converter
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 between or within buildings. The TCF-90 can be used for industrial applications and for applications that require secure data transfer. |

Patented Port Power Indicator LED
The TCF-90 has a built-in Port Power Indicator LED that can be used to determine if the TCF-90 is receiving enough power. The LED is used primarily to determine if the attached serial port can provide enough power to operate the TCF-90, which eliminates the need to use a multimeter. Simply connect the TCF-90 to the target RS-232 port, and then turn the SW4 switch to Test mode. If the LED lights up, the TCF-90 is receiving enough power. If the LED does NOT light up, attach the external
power cord to the TCF-90. |

Optional External Power Source
In most circumstances, the TCF-90 can get enough power from the attached serial device, in which case it does not need to connect to an external power source. If the attached serial device cannot supply enough power, you can use an external USB power cord (to connect to a PC's USB port) or DC power adaptor supply with applications for which the handshake lines are not available, both the RTS/DTR signals are set to OFF, or the interface chip of the attached serial port provides less power
than required. |
