RS232 RS485 RS422 TTL USB Fiber Optic Serial Converters / Adapters

We offer a range of high-quality, industrial-grade, port-powered RS232 to RS485 converters, RS232 to RS422 converters, and port or external-powered RS232 RS485 RS422 to TTL converters. These plug-and-play converter products operate within a wide temperature range (-40ºF to 185ºF / -40ºC to 85ºC), feature 600W surge protection and 15kV static protection, and come with built-in 120 Ohm terminators for easy installation. Whether your environment is commercial or industrial, "clean" or "noisy"*, our converter products provide safe, easy, and cost-effective solutions for your data-conversion applications.

* A "noisy" environment is an area surrounded by ground loops, transient surges and spikes, which could potentially harm your expensive equipment such as computers and data communication devices. The CommFront opto-isolated converters provide simple and effective ways to protect your devices from such potential harms.

We offer a range of high-quality, industrial-grade, port-powered RS232 isolators, opto-isolated RS232 to RS485 / RS422 converters, and port or external-powered RS232 Repeater / RS485 RS422 Repeater products. These plug-and-play products operate within a wide temperature range (-40ºF to 185ºF / -40ºC to 85ºC), feature 600W surge protection and 15kV static protection, and come with built-in 120 Ohm terminators for easy installation. Whether your environment is commercial or industrial, "clean" or "noisy"*, our isolator and converter products provide safe, easy, and cost-effective solutions for your data-conversion applications.

All of our USB to Serial Adapters use the latest FTDI chipset and is fully compatible with Windows 7/Vista/XP/Server2008/ 2003/2000/98 (32-bit), Windows 7/Vista/XP/ Server2008/2003 (64-bit), Win CE, Mac, and Linux.

The FBR-Serial-2 (Rack/Wall-mount) is an industrial-grade (wide temperature range with surge & static protection) 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.

Depending on the fiber cable and the type of converter used, a multi-mode fiber optic converter can extend the RS232 / RS485 / RS422 distance to up to 1.2 miles (2 km), while a single-mode fiber optic converter can extend the RS232 / RS485 / RS422 distance to up to 24.8 miles (40 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-Ethernet-2 is a 10/100M Ethernet to fiber optic media converter, which provides one channel for media conversion between 10/100BaseTX and 100BaseFX.

Depending on the fiber cable and the type of media converter used, a multi-mode media converter can extend the 10/100M Ethernet distance to up to 1.2 miles (2 km), while a single-mode media converter can extend the distance to up to 12.4 miles (20 km).

The FRB-Ethernet-2 is a plug and play unit featuring auto-negotiation for half or full-duplex and 10 or 100Mbps data rates, it also supports MDI (straight-through) and MDIX (crossover) cables, no DIP switch or jumper settings are required.

232Analyzer is an advanced serial port protocol analyzer software that allows programmers, engineers, and others to control, monitor and analyze serial port (RS232 / RS485 / RS422 / TTL, etc.) activities.

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.

232Analyzer is an easy-to-use program, yet it comes with many advanced features, including:

- Ability to monitor RS232/RS485/RS422/TTL communications with direction indication (including 2-wire RS485) and timestamps;
- Programmable buttons: Send up to 32 different commands with a button click (can be looped until manually stopped);
- Auto-response: Automatically responds to up to 16 different incoming data / signals;
- Macros: Up to 64 steps of logic and timer processes for handling sophisticated serial devices;
- Checksum calculator: Advanced checksum calculator for calculating sophisticated checksum bytes.

232Analyzer is useful for controlling, testing, developing, and debugging serial devices, control software, and firmware. It is widely used in industrial and commercial control and automation systems (our customers include Siemens, Honeywell, Johnson Controls, Schneider Electric, Ericsson, etc.). The FREE Limited Version has no time limitation, so feel free to use or distribute it.
