SERIAL / ETHERNET FIBER OPTIC CONVERTERS |
 |
The CommFront FBR-Serial-2 (Rack/Wall-mount) is a rugged, industrial-grade (-40F to 185F / -40C to 85C), multi-function RS232 / RS485 / RS422 to Fiber Optic Converter (fiber optic modem) that supports asynchronous serial communications (RS-232, RS-485, and RS-422) through fiber optic links. Besides the capability of long distance data transmission, fiber optic products are inherently resistant to EMI/RFI and transient surges; therefore, they are ideal for data communications near heavy electrical equipment and other electrical or radio interference.
This rugged industrial-grade Serial-to-Fiber-Optic converter operates within a wide temperature range (-40F to 185F/-40C to 85C), and features 600W surge protection and 15kV static protection. It requires no software drivers or flow control, making the unit a rugged, highly reliable, and truly plug-and-play device.
Depending on the fiber cable and the type of converter used, a Single-Mode fiber optic converter can extend the RS232 / RS485 / RS422 distance to up to 24.8 miles (40 km), while a Multi-Mode fiber optic converter can extend the RS232 / RS485 / RS422 distance to up to 1.2 miles (2 km). Standards can be mixed and matched, so RS-232 devices can be connected to RS485 / RS422 devices, or RS485 (2-wire) devices can be connected to RS422 (4-wire) devices without using a converter and isolator.
The FBR-Serial-2 comes with the options of ST, SC and FC connectors for fiber optic links, and, thanks to the professional and unique casing design, the product can be mounted directly on wall/panel or DIN Rail, without a need of using any unsecured adapters. A separate external power supply is included in the package.
Baud rates: 300 to 115.2K Baud.

The FBR-Ethernet-2 is a compact, rugged, light-weight, high-quality 10/100M Ethernet to fiber optic media converter, which provides one channel for media conversion between 10/100BaseTX and 100BaseFX. Besides the capability of long distance data transmission, fiber optic products are inherently resistant to EMI/RFI and transient surges; therefore, they are ideal for data communications near heavy electrical equipment and other electrical or radio interference.
This superior-quality industrial Ethernet-to-Fiber-Optic converter is enclosed in a heavy-duty, rustless ABS housing (the improved version of our previous steel housing), it operates within a temperature range of -40F to 185F (-40C to 85C), and features 600W surge protection and 15kV static protection. The unit features auto-negotiation for half or full-duplex and 10 or 100Mbps data rates, it also supports MDI (straight-through) and MDIX (crossover) cables, therefore, no DIP switch, jumper settings or software drivers are required, making the unit a highly reliable and truly plug-and-play device. Depending on the fiber cable and the type of media converter used, a single-mode media converter can extend the 10/100M Ethernet distance to up to 12.4 miles (20 km), while a single-mode media converter can extend the distance to up to 1.2 miles (2 km).
The FBR-Ethernet-2 comes with the options of ST, SC and FC connectors for fiber optic links, and, thanks to the professional and unique casing design, the product can be mounted directly on a wall, panel or DIN Rail, without a need of using any unsecured DIN-Rail or wall-mount adapters. A separate external power supply is included in the package, and the unit is backed by our 30-day risk-free money-back guarantee and 5-year replacement warranty.

232Analyzer supports data input and monitoring in ASCII, hexadecimal, decimal, octal and binary formats. It also allows you to monitor or change RS-232's Handshaking line states: RTS, DTR, CTS, DSR, DCD, and RI. With the port-powered RS232 to RS485/RS422 or RS232 to TTL converter, it also allows you to monitor or control RS485/RS422/TTL devices.
All data and handshaking signal flows are logged in the communication window, which can be saved as .txt, .doc or .rtf files for further analysis.

The Serial-TCP program (more than just a Device Server) bridges your existing Serial COM port and TCP/IP without the need for changing existing protocol. It works seamlessly and transparently, just like passive RS232 / RS485 / RS422 converters, repeaters, and hubs, while the difference is that one requires installation of cables and converters with limited distance; and the other simply makes use of the existing computers and networks with an unlimited transmission distance.
