Why EXSYS?

Reliable interface solutions with long-term driver support and industrial suitability

Long-Term Driver Support

EXSYS provides drivers for all current and many older Windows versions (from Windows 7), Linux kernel versions and macOS. Particularly important for industrial PCs in long-term installations: driver updates are maintained even for older operating system versions.

Galvanic Isolation for Industrial Environments

Selected EXSYS adapters feature galvanic isolation between the USB host and the serial interface. This protects the connected PC from overvoltages and ground loops in industrial environments with frequency converters, welding equipment or other sources of interference.

Plug-and-Play Without IT Effort

Many EXSYS products are automatically recognised by Windows and Linux (inbox drivers) or can be installed in minutes via the included setup package. No BIOS intervention or driver policy changes required – important for production environments with locked-down IT systems.

Industrial-Grade Form Factors

In addition to consumer form factors, EXSYS also offers robust variants with metal housings, screw locking and DIN rail mounting – designed for continuous operation in control cabinets and industrial racks. Ideal for OEM projects and series production.

Frequently Asked Questions about EXSYS

Answers for procurement and planning

Which EXSYS adapter is suitable for RS-485 networks in industrial environments? For RS-485 networks (e.g. Modbus RTU, DMX, BMS systems), EXSYS adapters with galvanic isolation, automatic transmit/receive switching and RS-485 termination resistor are recommended. Galvanic isolation prevents ground loops and overvoltage damage in multi-node networks with long cable runs.

Do EXSYS interface cards work under Linux? Yes. Most EXSYS PCIe interface cards are directly supported by current Linux kernels (inbox drivers). For older kernels or specific distributions, EXSYS provides source code drivers. This is particularly relevant for industrial PCs running Debian, Ubuntu and RHEL in production and laboratory environments.

Which EXSYS USB hubs are suitable for installation in 19" racks? EXSYS offers active USB 3.x hubs in 1U rack-mount form with 7 to 16 ports, dedicated power supply and per-port switching capability. These models are designed for continuous operation in server rooms and industrial racks, with metal housings and rack-screw mounting. Ideal for USB device servers and computer peripherals in data centres.
