USB Conversion

With our high-quality, high-performance USB converters that use only top-quality chipsets such as those from FTDI and Silicon Labs, USB signals are converted seamlessly into RS-232, RS-485, RS-422, TTL and Ethernet signals. You can confidently choose from our menu of industrial and commercial-grade devices, while knowing that you will get nothing but the best from CommFront.

Serial Conversion

CommFront offers a range of rugged industrial-grade RS-232 /RS-485 /RS-422 /TTL converters. These converters support multi-drop RS-485 /RS-422 networks and come with 600W surge protection, 15KV ESD protection, selectable end-of-line terminators, and optional 2500V optical-isolation circuitry, which ensure crisp data signals without interference for all types of installations.

Fiber Optic Conversion (Point to Point)

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 SFP connectors; point-to-point and advanced daisy-chain/self-healing redundant-ring fiber networks – giving your data networks unparalleled flexibility, reliability, and transmission range.

Ground Loops

Ground loop currents can flow through “the path of least resistance” via either the common earth ground or the ground wire and cause serious damages to the connected devices.

Optical isolation uses an LED (Light Emitting Device) and a photosensitive transistor to transfer data across the isolation barrier - typically an air gap; in other words, data is transmitted using light instead of electrical signals, so there is no physical connections between the grounds and the data lines, thus removing the ground loop problems.

Remote Lightning

Serial networks are often exposed to remote lightning because of the long distances and the surrounding electrical equipment.

Optical isolation uses an LED (Light Emitting Device) and a photosensitive transistor to transfer data across the isolation barrier - typically an air gap; in other words, data is transmitted using light instead of electrical signals, so there is no physical connections between the connected devices, thus effectively preventing remote lightning, voltage surges, and sparks from destroying other parts of the system.

Voltage Surges

Because of the long distances and the surrounding electrical devices, voltage surges can run across the system and cause damages to the valuable equipment.
