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.

5.2. Auxiliary processor module

Router contains an Auxiliary CPU with CORTEX processor. Auxiliary CPU controls modems and GPS. The Auxiliary CPU communicates with Master CPU by Auxiliary processor commands. By using these commands it’s possible: Find-out FW version Control modem power supply

6 PE Device chassis

Router can be powered only by DC power supply with nominal voltage.

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 separation must not be used for dangerous voltages separation.

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 conductors cross-section must be at least 0.75 mm2. SB Device status

Vcc Device is ON

GND / not connected Device is OFF

After disconnecting the SB pin from supply voltage is launched the procedure for system switching off. Router is switched off immediately after completion of 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.

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. 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.

Router is turned off by turning off power supply voltage.

7. Digital inputs / outputs

Router is 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.

8.1. Ethernet

Router is equipped with two independent Ethernet interfaces, each with its own MAC address. First interface on X2 connector is used for connection to LAN network within railway vehicle, and it is recommended to connect to it devices with as low bandwidth as possible, due to the fact that X2 line loads main CPU.

Interface can be operated with 10/100/1000 Mbps speed. Second interface is located on the rest of Ethernet connectors X3 to X7. The number of connectors (0 × to 5 ×) differs according to variant. They are connected to integrated Ethernet switch.

Interface can be operated with 10/100/1000 Mbps speed.

When using 10/100 Mbps speed and four-wire cable with counterpart supporting 1000 Mbps speed, it is necessary to prohibit 1000 Mbps speed promotion at least on one side. Otherwise auto-negotiate function (transmission speed auto-detection) may not succeed. On switch interface this can be set from application program. Router interface is fitted with M12 connector, 8 pins, X-coding according to IEC 61375-3-4:2014.

8.2. WiFi

WiFi interface is used for connection of users to access point. There are 2 WiFi interfaces available, and each has two RSMA connectors for antenna. WiFi interface complies with family of standards IEEE 802.11 type a, b, g and n 2.4 GHz and 5 GHz.

Fig. 14 - Location of LEDs and connectors for WiFi

WiFi module allows connection with one antenna with SISO configuration, or two antennas with multiplex 2 × 2 MIMO configuration.

8.2.1 Transmission speed

The theoretical speed is normally indicated by manufacturer, but in real life even under optimal conditions only one-third of indicated speed can be expected. Transmission speed depends on used 802.11 standard. Configuration Theoretical

transmission speed Real transmission speed

SISO 1 Mbps to 54 Mbps 0.3 Mbps to 18 Mbps

MIMO 300 Mbps 100 Mbps

Transmission can be secured by WEP, WPA, WPA2 or 802.1x technologies.

8.2.2 Connection of antennas

For good quality of signal transmitted between access point and counterpart device it is necessary to maintain certain rules, also it greatly depends on type of used antenna. If the antenna is directional – it should be directed towards to the counterpart

device. Between antenna and counterpart device there should be as few obstacles

(especially metal obstacles) as possible. When using MIMO – it is good to point antennas at a slight angle from each

other.

13. Mounting, installation rules

13.1. Mounting instructions

Router can be mounted in any position. To ensure proper cooling and access to router we recommend to keep a free space of minimum 70 mm sidewise and 100 mm from the upper surface of the radiator. Alternatively, cooling can be arranged by additional means (fans, another measures). Free space of at least 10 cm must be left on the side of the connectors for cable connection and fastening.

It is very important to ensure that ambient temperature does not exceed the allowed limits. Moreover, it is necessary to ensure that heat radiation equipment located nearby does not cause exceeding of temperature limits. Due to its weight, router must be mounted on sufficiently dimensioned wall of vehicle body. Sufficient dimensioning of fixtures/brackets and screws is also needed.

13.2. Cabling

PE terminal of power supply connector must be connected with local installation earthing terminal.

Minimum cross-section of supplying conductors must be at least 0.75 mm2.

The cables or individual wires being connected to the device must be protected against mechanical stress. Cables or individual wires must be protected against mechanical stress by binding to solid installation parts. Length of cable or individual wire between last binding point and the control unit connector should not exceed 15 cm.

Ethernet line connection must be carried out using shielded cables of category CAT. 6 and higher.

Data communications and I/O signals interconnections must be done with shielded cables. Shielding must be connected either to metal connector caps or to router PE terminal.

All PE connections must be realized with as low as possible impedance.
