LONWORKS Bus Topologies

The LONWORKS Bus is a 78-kilobit serial link that uses transformer isolation so that the bus wiring does not have a polarity. I.e. it is not important which of the two LONWORKS Bus terminals are connected to each wire of the twisted pair.

The LONWORKS Bus does not need to be shielded on the controller module side.

The LONWORKS Bus can be wired in daisy chain, star, loop or any combination thereof as long as the maximum wire length requirements are met.

Configuration

The recommended configuration is a daisy chain with two bus terminations. This layout allows for max. LONWORKS Bus lengths, and its simple structure presents the least number of possible problems, particularly when adding on to an existing bus.

C-Bus Topologies

Via the C-Bus up to 30 C-Bus devices (e.g., controllers, etc.) can communicate with one another and a PC central. The C- Bus must be connected via the individual controllers (open ring).

NOTE: Star connection is not allowed because uncontrollable line reflections may occur.

WARNING

Risk of electric shock or equipment damage!

►Do not touch any live parts in the cabinet.

►Disconnect the power supply before you start to install the Excel 800 System.

More than one disconnect switch may be required to de- energize the system.

►Do not reconnect the power supply until you have completed the installation.

NOTE: The terminal socket of each I/O module can be mounted and wired before inserting and locking the corresponding electronic module.

XL 800 SERIES specifications

The Honeywell XL 800 Series represents a significant advancement in the realm of flight management systems, tailored for general aviation aircraft. This series stands out due to its combination of state-of-the-art technology, user-friendly interface, and comprehensive functionality, all designed to enhance safety and operational efficiency for pilots.

One of the main features of the XL 800 Series is its advanced flight planning capabilities. The system is equipped with a robust database that allows pilots to create, modify, and execute flight plans with unprecedented ease. The built-in terrain awareness tools provide real-time information about geographical obstacles, helping mitigate the risk of Controlled Flight Into Terrain (CFIT). The intuitive graphical user interface offers a clear view of the flight path, airspace constraints, and available alternatives, enabling pilots to make informed decisions.

The XL 800 Series also boasts cutting-edge navigation technologies, including GPS, RNAV, and WAAS (Wide Area Augmentation System) support. These technologies ensure that flights are accurately tracked and that pilots remain on course, enhancing navigation reliability. Additionally, the system includes advanced autopilot features, which allow for smoother transitions during flight phases and can significantly reduce pilot workload.

Another notable characteristic of the XL 800 Series is its connectivity. The system supports data link services that enable real-time weather updates and air traffic control communication. This connectivity not only improves situational awareness, but it also equips pilots with the necessary tools to adapt to changing flight conditions promptly.

Furthermore, the Honeywell XL 800 Series prioritizes safety with integrated safety features, including enhanced cockpit alerting systems. These systems proactively notify pilots of potential hazards, such as deviations from the flight path or adverse weather conditions, ensuring that safety remains paramount throughout the flight.

In summary, the Honeywell XL 800 Series encapsulates a wide array of features and technologies that serve to elevate the flying experience for general aviation pilots. Through its emphasis on flight planning, navigation, connectivity, and safety, it stands as a reliable and sophisticated solution that meets the demands of modern aviation. Whether enhancing safety, improving navigation accuracy, or simplifying flight planning, the XL 800 Series is a premier choice for those seeking an advanced flight management system.
