In modern ship bridge design, the flexibility, reliability, and maintainability of instrument systems have increasingly become the focus of attention for ship owners, designers, and crew members. Traditional analog indicators are limited by mechanical structures, and each parameter requires an independent instrument, which not only occupies a large amount of panel space, but also increases spare parts inventory and maintenance complexity. The XDi series flexible display indicators launched by DEIF, with virtual indicator technology as its core, completely breaks this limitation and provides a new instrument solution for applications such as ship propulsion control, navigation monitoring, and power positioning.
Product positioning and core philosophy
The XDi series is a patented lighting indicator display series developed by DEIF, which uses virtual display technology to integrate the functions of traditional multiple physical instruments into one or more high-resolution displays. This series of products breaks through the physical limitations of mechanical instruments, and through pre installed indicator libraries and flexible configuration options, allows crew members to combine and display multiple parameters on a single display screen, such as speed, pitch, azimuth, or speed, heading, water depth, etc.
1. Industry disruptors
The XDi series is known as the "game changer" of bridge instruments, mainly reflected in the following aspects:
Save panel space: A single XDi indicator can replace multiple traditional instruments, significantly reducing the footprint of bridge control consoles
Simplified installation: reduces wiring workload, lowers installation time and costs
Flexible configuration: Indicator layout and parameter settings can be completed on site during installation
Convenient maintenance: Backup units can be quickly replaced without waiting for customized instrument spare parts
2. Application case: ZF Marine Krippen
ZF Marine Krippen adopts the XDi solution in its scalable azimuth thruster control. The traditional solution requires configuring different indicator dials for different working modes, while XDi can automatically switch the indicator display range according to the thruster mode. R&D engineer Johan Spruyt said, "With XDi, we have greatly saved space on the bridge operation panel, while simplifying daily operations. Regardless of the working mode, only one thruster indicator display screen is needed. ”
3. Application case: The world's first zero emission electric tugboat
ZeeTug, the world's first zero emission all electric tug, was built by Navtek Naval Technologies, a Türkiye ship designer. Its propulsion control system is integrated by BMA Technology. In this project, BMA Technology selected the highly customizable XDI 192 N indicator from DEIF and utilized its mode switching function to preset up to 4 screens on a single indicator, displaying relevant data for different combinations.
Product series and variants
The XDi series is divided into the following models based on display capability and interface configuration:
Model Function Description
XDi Dual displays 1 or 2 input values, suitable for dual parameter monitoring scenarios
XDi Multi displays multiple input values according to application requirements, suitable for complex parameter combinations
XDi-N is equipped with NX2 NMEA input/output module, supports XDi-net network sharing, and can switch between up to 4 screens for display
As a platform 2 product, XDi-N has more powerful features:

2. Product configuration files and virtual indicators
The library file contains preset content at the following three levels:
Product configuration file: includes CAN bus default parameters, dimmer group, input types, alarm and sound settings. NMEA settings are also pre-defined in the configuration file.
Virtual indicator: includes graphic design, which can be a DEIF standard design or a unique design customized according to customer needs. The graphic design complies with relevant ship standards and cannot be modified by users. The single virtual indicator of XDi-N can contain up to 4 screen designs, and users can switch between them.
Virtual indicator settings: Each virtual indicator has one or more settings configuration files that define unique configurations for input, output, control, and optional titles.
Customized solution
DEIF provides three levels of customized services to meet various needs from standard applications to complete branding.
1. Customization level 1: Standard combination library
If users frequently use the same set of standard indicators (such as combinations from azimuth thrusters, tunnel thrusters, and rudder angle libraries), DEIF can compile and pre install these indicators into a customized library for a one-time fee. The indicator content remains unchanged, organized only according to user preferences.
2. Customization level 2: Parameter adjustment
According to system requirements, fine tune standard indicators or default settings parameters to reduce installation site configuration time. The cost of this level is slightly higher than level 1.
3. Customization level 3: Fully customized
Suitable for customers who need unique designs that are consistent with the corporate brand image. DEIF leverages its experience in graphic design and system integration to create a complete custom library for clients. Common customization features include:
Virtual Indicator Design
Product matches customer system with input configuration file
Key frequency band setting
Relay output controlled by critical frequency band
Pop up windows and graphic symbol changes controlled by input values or thresholds
4. Customization of Front Frame Logo
For customers who wish to display their corporate logo on the indicator, DEIF recommends placing the logo on a detachable front frame. Adding a logo to virtual indicator design can take up valuable display space, reducing flexibility and readability.
Installation and configuration process
1. Physical installation
The XDi series adopts a standard panel installation method and is configured and upgraded through the rear USB interface. The expansion module adopts a "quick snap" design, which can be easily installed behind the host:
XDi 96 supports up to 1 expansion module
XDi 144/192 supports up to 2 expansion modules
The types of extension modules include:
NX1: 2 contact inputs for remote button control

2. Installation Wizard and Configuration Lock
After XDi is powered on, it automatically starts the installation wizard and guides users to complete the initial setup:
Definition and locking: Assign CAN node ID, XDi marked as "available but not set" on the CAN bus
Automatic setting: XDi receives configuration from the CAN control system, locks the configuration after completion, and enters normal operation
Manual setting: Follow the wizard instructions to set application parameters, including red scale markings, etc
Final confirmation: After completing the setup, lock the configuration and ensure that the indicator meets the approval and regulatory requirements of the bridge indicator system
For XDi-N models, NMEA settings can be easily accessed in the final stage of the wizard.
3. On site configurable functions
Red Mark Setting: Up to 4 integrated scale red marks can be defined and set on site (if this function has been activated in the library)
Daytime and Nighttime Scale: The standard library includes both daytime and nighttime designs, and dusk design can be added upon request
Front button control: The front button allows for easy screen switching, dimming, and unit conversion. In the XDi-N system, pressing a button can simultaneously control the display of all XDi-N units within the group

XDi net and mode switching function
1. XDi net network
The XDi-N model supports XDi-net through the NX2 module, which is a network protocol based on the CAN bus and has the following characteristics:
Up to 5 indicators can be connected to the same CAN bus, sharing XDi net
NMEA data is shared via CAN bus
The front button can control the dimming level of all indicators within the group
2. Mode switching function
The virtual indicators in the XDi-N library can contain up to 4 screens, each of which can be assigned to modes 1 to 4. By default, Mode 1 corresponds to Screen 1, and so on. But users can assign any screen to any mode number.
Application example: In a system containing 4 XDi indicators, 4 operating modes can be configured:
Port mode
Navigation mode
Homework Mode
Information mode
The captain can switch all four indicators to the corresponding mode of screen display by pressing a button based on the current operational status. Screen allocation can be set through a shortcut menu, and the same screen can be assigned to multiple modes.
Mode switching method:
Use the left button of any indicator to switch
Switch through external buttons connected to NX1 or NX2 modules
Digital input through DX1 digital module (can be set to select modes 1-4)
Controlled by the integrated control system through CANopen or digital control input
Software updates and spare parts management
1. Convenient update mechanism
The XDi has a built-in USB interface at the rear, which allows for easy upgrading of library files or other updates. All standard libraries and customized libraries can be downloaded and uploaded to XDi devices for free. Even if you choose the wrong library file when ordering, there is no need to worry, it can be easily corrected on site.
2. Spare parts strategy
Due to XDi's integration of a virtual indicator library, solutions, and settings, fault issues can be immediately resolved by trained personnel. Reserve spare units of various sizes on board, and the crew can complete the replacement of faulty units within a few minutes, allowing the system to resume operation without waiting for customized instrument spare parts.
