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. |
