1 Introduction
RB-RTExxx is a family of Ethernet TCN routers for rolling stock. Within the
railway installation, the router provides connection between ETB and ECN
Ethernet networks. Hereinafter in the text it will be referred to as router.
Router contains the processor module with Intel Atom processor.
Router is supplied without application. Application is loaded by user during
installation of the device.
▪CPU Intel Atom E3815 1.46 GHz
▪2 GB DDR3L RAM
▪4 GB eMMC FLASH
▪RTC, RAM and BIOS CMOS backup by battery, optional
▪1 Gbps M12 X-coded ETB and ECN Ethernet ports
▪2 × ETB ports with bypass function
▪2 × ECN ports
▪2 × USB 2.0 host
▪1 × RS232 serial service interface
▪1 × HDMI service interface
▪2 × DI/DO (optional)
▪Power supply with GI and nominal input voltage of 24/36 V DC
▪LED indicators
▪Mounting on base plate
▪Rolling stock electronic device
▪Design according to EN 50155
Router is designed so that operates immediately after switching on within the
whole operating temperature range, without need of tempering.
Router is designed to be used with Linux operating system.

5 Processor modules
5.1 Master processor module
For master CPU, router uses a processor module with CPU Intel Atom.
The core contains processor Intel® Atom™ E3815 2 GB DDR3L, 4 GB eMMC.
For more details see the MSC Q7 module datasheet on manufacturer's website
(see Related documentation).
Master CPU module is equipped with eMMC (NAND flash) type memory.
Therefore, when keeping the memory lifetime in mind it is recommended to
minimize the number of writing cycles.

Device chassis
Router can be powered only by DC power supply with nominal voltage as
specified in chapter 2.
Power supply voltage is connected to power supply terminals Vcc and GND of
X1 connector. Terminal SB is used for turning router on and off, terminal PE is
used for connection to chassis.
Power supply (terminals Vcc, GND and SB) is galvanically separated from
internal electronics. Galvanic isolation must not be used for dangerous voltages
isolation.
When installing, it is recommended to connect the PE terminal in single point of
switchboard with chassis of equipment where the router is installed.
The power supply conductor’s cross-section must be at least 0.75 mm2.

After disconnecting the SB pin from supply voltage is launched the procedure

operating system run –it takes no more than 1 minute.
The PE terminal is internally connected with router casing and with metal caps
of all connectors.

6.1 Computer start up and shut down
Router is turned on after connection of power supply to Vcc and GND terminals
and activation by SB signal.
6.1.1 SB input is used
In terms of data consistence, the unit's start-up is not critical and can be
realized either by coincident connecting of power supply voltage to Vcc and SB
terminals, or by connecting the voltage first to Vcc terminal and then to SB, or
vice versa. Nevertheless, when starting up, an incorrect progress is not
possible.
To prevent data damage the unit must be shut down only by SB terminal.
First, it’s necessary to disconnect the supply voltage from SB terminal, thereby
is initiated a correct process of systemic termination of application and
operating system run. Only after completion of operating system run and unit’s
shut down, the supply voltage can be disconnected from terminal Vcc, or
voltage can be left connected to Vcc terminal permanently.
Voltage waveforms during correct and incorrect switching ON are shown on
following figures.
Vcc …External power supply
SB …Voltage on SB pin
HW …Unit power supply
APP …Application running / not running
ton …Time between power-on and application start-up
toff …Time between deactivation of SB and router power-off
Correct turning on process is ensured by device construction. Correct shut
down process is when the application turns off during toff1.

terminals, or by connecting the voltage first to Vcc terminal and then to SB, or
vice versa. Nevertheless, when starting up, an incorrect progress is not
possible.
Signal SB can be connected directly with device Vcc terminal. Operating
system must be designed so that instant shutting down could not cause
damage the data.

7 Digital inputs / outputs
Router can be equipped with two input / output pins, located on power supply
connector. Both are galvanically separated from the router electronics.
Pins can be used as an inputs or outputs with backward reading, bun never as
input and output simultaneously.
