DG-PID21-R is a rugged purpose-built stand-alone IP connected Intelligent Passenger Information Display for bus applications which require high service reliability and easy integration with other in-vehicle systems. The PID21-R bases on a low power i.MX8 CPU which can include Duragon’s proprietary firmware or third party PID-system Client Software. The intelligent display can deliver media content combining video, animations with static or changing images on the HD resolution display. Route and operational service information can be combined with advertising content. Ethernet is used for integration with other onboard systems. Display content is not streamed over Ethernet, only control information is sent over the network. Media is stored in the PID21-R and it can be updated over the Ethernet backbone. The internal Ethernet switch with its two external ports, enables the connection of multiple PID21-R displays in series. In case there is a HW or other internal failure, the bypass relays will automatically disengage a faulty device from the Ethernet network.
Functionality is optimized in the PID21-R intelligent display. A high brightness and contrast LCD display supports full HD resolution. The internal single control board includes a i.MX8 CPU, supervised by a microcontroller which manages all the display’s functionality including safe power on-off, secure booting, backlight brightness, temperature monitoring and event logging. The integrated widerange railway grade power supply can reliably directly connect to a 24VDC nominal power supply.
Our design approach reduces lifecycle costs and migration challenges. The technology of the PID21-R is based on commercial standards, Industrial-Grade components and a design leveraging 20+ years of paradigm experience in vehicle systems design.
Purpose built – The DG-PID21-R Passenger Information Display’s architecture, functionality, enclosure, connectors and structure are designed for high availability and 24/7 operating Ethernet connected bus or tram applications. The DG-PID21-R display integrates a proprietary Freescale i.MX8 graphics control computer, vehicle PSU, management microcontroller and Dual-Port Ethernet switch with Bypass Relays.
Resistant – DG-PID21-R is designed to withstand the mechanical, electrical and environmental stress encountered in bus installations in arctic and tropical conditions.
Wide temperature range – A wide operating temperature range ensures reliable continuous operation from -25~ +55°C. The system is completely fanless and features conduction cooling and an internal temperature monitoring and thermal protection system.
Compliance – The DG-PID21-R display is compliant with:
- EN50155, EN61373 (Shock and vibration)
- IP52 according to IEC 60529
Connectivity – Comprehensive set of connectivity interfaces

Functionality – The PID21-R is fully autonomous in its operation. This device can perform signage, interfacing over Ethernet with other systems on the bus. The dual Ethernet ports support “Daisy-chain” operation, reducing cabling and In-Vehicle Ethernet switch ports. Media content is stored locally and can be updated over the Ethernet interface from an onboard Single Control Unit or Telematics Server.
The system bases on open Linux OS and high level rapid graphical development tools are available. The internal uC ensures safe start-up with system health monitoring as well as thermal throttling of the CPU and the backlight.

The DG-EL1696-P5B is a rugged LED passenger information display targeting bus installations. This display is purpose-built with protected and EMC filtered RS-485 and CAN 2.0 interfaces and an automotive grade power supply, which can directly connect to the vehicle’s 24VDC battery system. The electronics of the display is full SMD to increase mechanical reliability. The display is based on a 32-bit CORTEX-M3 microcontroller with dedicated firmware, which can be customized to meet the specific requirement of each project, including custom graphics elements and language support. Error and diagnostic codes are available to monitor the health of the display and its correct operation. Constant current LED sink drivers are used to drive high brightness SMD LED components to increase the optical performance and ruggedness of the display. The LED matrix brightness can be adjusted from 0 to 100% under software control or automatically adjusting to daylight conditions. The brightness of the LEDs is thermally throttled to protect components at high ambient temperatures. The display base is black for improving contrast. The LED area is covered by a tamper proof safety glass. The LED display is based on boards which include 16 x 32 LEDs, the master board connects to the slave boards with board-to-board connectors. This modular approach enables the adaptation to different LED matrix sizes. Each board has its own local tightly regulated power supply for improved power distribution. The RS-485 interface or CAN 2.0 interface can be used for host communication using a HEX-format based protocol for commands and controls. The host can interrogate display status including supply voltage, internal temperature, ambient light level as well as the diagnostic status of individual LEDs is the complete matrix. A LED diagnostic check is performed when power is applied to the display.
