DG-DRM48E-R - Ultra Wide 48" 16:3 LCD Railway DRM/PIS Display
OVERVIEW:
DG-DRM48E-R is a standalone ultra-wide screen Ethernet-connected sunlight readable 48" 16:3 aspect ratio LCD DRM-display. This display is purpose-built for rolling stock PIS or Dynamic Route Map applications, which require connectivity over Ethernet. An proprietary 64-bit 6-core RK3399 ARM SoC based sytem board controls the display and the media delivery. Dual 10/100Mbit Ethernet ports enable "daisy-chaining" multiple displays together. This reduces the number of ports required on the consist network switch. Each device has its own Ethernet switch for port expansion and the physical Ethernet Interfaces include bypassing relays, which guarantees the integrity of the series-connected Ethernet in case of device failure. In the event of a failure, the safety relays will disconnect the DRM from the Ethernet and bypass the device internally.
The DG-DRM48E-R is protected against excessive temperature conditions and fetaures an internal temperature dependent backlight brightness control and CPU speed throttling. The application software can be developed using the QT-toolchain, which accelerates the creation of the application software and enables independent maintenance of the GUI. An inbuilt 1500VDC wide input range isolated power supply can directly connect to the 110VDC train feeder power source.
