What in the hark is this?
This is a Dynamic Passenger Infromation Display (DRIS) We got one from the Province since they are upgrading them to newer units.
Information gathered
Hardware
Power supply
- Tracopower 12v / 6.0a (Supply for IO)
- Tracopower 3.3v / ? (Supply for Leds ) BROKEN
- Tracopower TMT 15105C 5v (Supply for led and FPGA board)
Controller Board
Main controller board which is connected to the led panel. Seems to communicate over serial with the build-in PC. The heart of the board seems to be a ST10f276Z5Q3 which is a 64Mhz 16-bit MCU. The UART seems to be handled by a TL16C550CIFN.
So far from glancing around we found that:
- It is NOT a FPGA but instead has a 16bit MCU
- It has a RTC
- It has both RS422 and RS485
- It has ethernet
- It has various IO of which the following devices are connected to it
- A temperature sensor
- A light sensor
- A sense for the bus bar for the leds
Unknown modem board
I haven't been able to detect a serial number yet. It has a sim slot with a KPN sim card in it and is connected to the PC with two com ports. It also seems to act as a watchdog as the PC's power is directly connected to it and it reboots the PC.
PC
Motherboard still unknown. It has an Atom CPU and 1 GB of ram. On the board is a 4GB Sata DOM.
OS
It's running Windows XP Embedded the controller software seems to be written in Java. A raw disk image of the IDE dom can be found on Harmony under "shared_nurds_folder/Dris Display" along with the extracted partitions with zip.
