Convert - A Mastery of Legacy and Leading-Edge Data Formats

The world today runs on data! From legacy serial communications to modern TCP/IP communications, data networks are widely used in automation, control, and communication systems that perform many important tasks ranging from production, communications, security, surveillance, to research. Modern data networks often face the challenge of merging legacy data formats and protocols with more technologically advanced formats. In addition, interference can seep into the communication lines from many sources, such as ground loops, spikes, transient surges, and remote lightning. All these sources threaten your valuable and mission-critical equipment and your production time, which is probably the most important factor to consider when choosing data communication products and suppliers.

For the past decade, CommFront has built a reputation as a major supplier of rugged and reliable, yet simple, data communication products and solutions. Our versatile products make converting between many data formats – including the legacy RS-232, RS-485, RS-422, and TTL; and the leading-edge USB, Ethernet, and TCP/IP - smooth, simple, and reliable. Our line of rugged, industrial-grade, SGS / TUV-certified converters undergo rigorous testing so that you can enjoy reliable interfacing. These rugged converters withstand the harshest operating environments and come bundled with optional optical isolators and built-in selectable end-of-line terminators, allowing for interfacing between commercial and industrial equipment (computers, PLC, RTU, SCADA, and HMI, etc.) without interference from noise, reflections, ground loops, and transient surges. Our range of converters - standard or optically isolated, port or externally powered, copper-wire or optical-fiber - ranks among the widest in the market. If you have a data format, we have the perfect device for it.

Fiber Optic Conversion

fiber optic conversion

Our fiber optic converters run on a light-speed fiber backbone that is inherently resistant to radio and electrical interference, such as EMI / RFI, lightning, transient surges and ground loops. These converters extend serial (RS-232 / RS-485 / RS-422 / TTL) and Ethernet signals with many options - single-mode and multi-mode; ST, SC, FC and LC connectors; point-to-point and advanced daisy-chain/self-healing redundant-ring fiber networks – giving your data networks unparalleled flexibility, reliability, and transmission range.
