  2. PCI Express - Wikipedia

    en.wikipedia.org/wiki/PCI_Express

    PCI Express 2.1 (with its specification dated 4 March 2009) supports a large proportion of the management, support, and troubleshooting systems planned for full implementation in PCI Express 3.0. However, the speed is the same as PCI Express 2.0.

  3. Variable-frequency drive - Wikipedia

    en.wikipedia.org/wiki/Variable-frequency_drive

    Small variable-frequency drive Chassis of above VFD (cover removed). A variable-frequency drive (VFD, or adjustable-frequency drive, adjustable-speed drive, variable-speed drive, AC drive, micro drive, inverter drive, variable voltage variable frequency drive, or drive) is a type of AC motor drive (system incorporating a motor) that controls speed and torque by varying the frequency of the ...

    en.wikipedia.org/wiki/AS-interface

    ASi-5 uses a novel communication method. The new ASi-5 technology allows the use of ASi-3 components together with components of the new ASi-5 technology on a common cable. If ASi-3 devices are to be used together with ASi-5 components, then in addition to the corresponding devices the use of a new ASi-3 / ASi-5 master is required.

    4 High-density external connector (also used as an internal connector). SFF-8482 [31] [32] internal 29 2 lanes This form factor is designed for compatibility with SATA but can drive a SAS device. A SAS controller can control SATA drives, but a SATA controller cannot control SAS drives. Lower pins (S1-S7, P1-P11) defined as in SATA.

  6. SERCOS III - Wikipedia

    en.wikipedia.org/wiki/SERCOS_III

    A standard Ethernet controller can be used for applications with line topology, bus cycle times greater than 500 us, and microsecond range synchronization. Applications with higher synchronization requirements and lower bus cycle times can be implemented using a TTS-capable Ethernet controller with a suitable real-time operating system.

  7. LonWorks - Wikipedia

    en.wikipedia.org/wiki/LonWorks

    Two physical-layer signaling technologies, twisted pair free topology and power-line carrier, are typically included in each of the standards created around the LonWorks technology. The two-wire layer operates at 78 kbit/s using differential Manchester encoding, while the power line achieves either 5.4 or 3.6 kbit/s, depending on frequency. [2]

  8. RS-485 - Wikipedia

    en.wikipedia.org/wiki/RS-485

    RS-485 signals are used in a wide range of computer and automation systems. In a computer system, SCSI-2 and SCSI-3 may use this specification to implement the physical layer for data transmission between a controller and a disk drive. RS-485 is used for low-speed data communications in commercial aircraft cabins' vehicle bus. It requires ...

    AFDX is one implementation of deterministic Ethernet defined by ARINC Specification 664 Part 7. AFDX was developed by Airbus Industries for the A380, [3] [4] initially to address real-time issues for flight-by-wire system development. [5] Multiple switches can be bridged together in a cascaded star topology. This type of network can ...
