3 Product Introduction
XDi is an illuminated bridge indicator where a high quality display replaces the mechanical scale and pointer
combination. A high number of predefined virtual indicators (VIs) can be stored in the built-in memory. VIs are
organised in a library structure.
This high flexibility is implemented much in line with the way that we handle our traditional XL family of indicators
and in a controlled manor not compromising the ability to make customised indicator libraries and most important,
still securing the needed approvals for relevant indicator applications on the ship
’s bridge.
DEIF offers a series of standard libraries with a selection of often-used indicator types and in addition, the
opportunity to have customised libraries designed.
Four push-buttons hidden behind the front frame combined with the installation wizard makes it easy to select the
right indicator during first time installation and to make necessary parameter adjustment via the user or installation
menu.
XDi normally replaces two or more traditional, class-approved, illuminated indicators that are very often part of the
safety system on-board the ship. In an emergency, it is very important that such indicators present exactly the
expected data type, and it is therefore not allowed to change between presentations of different data types on such
indicators during normal operation.
After installation, the front frame is mounted, hiding the four buttons, and the selected virtual indicator will be fixed,
most likely for the rest of its life.
The graphical display allows a high flexibility in both design and configuration. The XDi concept is made with easy
customisation in mind, making it possible to make highly customised indicators, still based on the type-approved
standard XDi platform.
XDi is available in three different physical sizes: XDi 96, XDi 144 and XDi 192, each with performance class:
•
Dual, where indicators may present data from a single or two input sources
•
Multi, where indicators may present data from multiple data source, normally between 1 and 8.
•
Nav, optimized for presentation of navigation related data, but not limited to that
The basic XDi unit is equipped with two galvanic separated CAN ports as standard data interface.
Adding an AX1 extension module, analogue inputs are available, and by adding a DX1 digital I/O extension
module, digital inputs and relay outputs are available.
When other systems like a VDR or integrated navigation system needs data input from an XDi based indicator
system, it is possible to add the NX1 NMEA output extension module to output relevant NMEA data sentences.
With the NX2 NMEA input/output extension module several serial input and/or output ports are available for
reception or transmission of NMEA data. This module is mainly intended for the XDi-N version.
For technical details about the different extension modules, please see the XDi data sheet.
