General information

1.1 Operational description

Sirius DDT TAGBOARD is an industrial computer, with real time capabilities, based on MPC5125; directly
powered at 24Vdc.

The operating system that comes with it is UNIX-LIKE and is based on the linux kernel. The distribution is
an OpenEmbedded / Yocto derivative and allows the management of applications through packets.

Thanks to the Xenomai scheduler, you can create tasks with real-time characteristics entirely in userspace.

Peripherals include two Ethernet devices, three CAN channels and two optocoupled serial ports.

Hardware

2.1 Introduction

Sirius TagBoard DDT is a real time industrial computer.

The microprocessor is a MPC5125 PowerPC with a clock frequency of 400MHz, coupled with a 16-bit
PIC co-processor for the management of some non-critical tasks.

There are 256MB of DDR2 RAM, 8MB NOR for the kernel and boot, 2GB eMMC for the file system, 128kB
SRAM with battery backup and 1GB or 4GB NAND.

DDT has following communication interfaces:

• 3 optocoupled CANopen ports

• 1 10/100 ethernet port

• 1 three way 10/100 ethernet switch

• 2 optocoupled serial ports, configurables as RS232, 485 o 422 according to wiring

• 2 USB 2.0 ports

• 1 programmable dot matrix informative panel

• 1 microSD card slot
