5. Processor modules
5.1. Master processor module
For master CPU, access point 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.

6. Power supply
Access point power supply connector contains power supply inputs and two
digital inputs / outputs. Voltage level of power supply and digital inputs / outputs
corresponds with power supply voltage 24 V DC.

Connection to chassis
Access point 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 access point 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 access point is installed.
The power supply conductors cross-section must be at least 0.75 mm2.

After disconnecting the SB pin from supply voltage is launched the procedure
for system switching off. Access point is switched off immediately after
completion of operating system run –it takes no more than 1 minute.
The PE terminal is internally connected with access point casing and with metal
caps of all connectors.

6.1. Computer start up and shut down
Access point is turned on after connection of power supply to Vcc and GND
terminals and activation by SB signal.
6.1.1 SB input is active
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 the data damage the access point 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

Correct turning on process is ensured by device construction. Correct shut
down process is when the application turns off during toff1.
