F1 (SERCOS 1)F2 (SERCOS 2)
Use an adequately sized wire, according to the current flowing. A lower cross-section might
cause fire, due to overheating caused by the wire.
In order to meet the requirements of the EMC 2014/30/UE, the cable must not be longer
than 30 meters.
The MST S4 module is a high-tech electronic device, sensitive to electrostatic discharges
(ESD). Take maximum care to prevent such discharges, by adhering to the prescriptions of
the law, in order to avoid damages to the device.
8.4 Sercos III connectors
The device features two connectors Sercos III, installed on the upper side of the device, used for the commu-
nication with other devices equipped with SIII field-bus interface. As specified in the standard protocol Sercos
III, there is no functional difference in using connector F1 or F2, therefore it is possible to connect the field-bus
cables in any order. The pin configuration of the connectors is standard for Ethernet wiring; therefore, it is pos-
sible to use common Ethernet cables (min. FTP Cat. 5E) to connect the MST S4 module to Sercos III bus.

8.5 USB port
The USB connector is located on the underside of the module. The type of connector used is the most common
type: type A USB 3.0. The USB 3.0 port is compatible with the USB 2.0 standard.
8.6 Ethernet ports
There are two 10/100/1000 Mbps Ethernet ports located at the bottom of the device which use standard RJ45
Ethernet connectors. It is therefore possible to use common Ethernet cables to connect the CPX 04XX
module to the local network.
Each Ethernet port features two LEDs: the first one, identified by the letter S, indicates the communication
speed of the concerned port. It is a bicolor lamp (green/orange); it changes its colour according to the
communication speed of the Ethernet port.
The second one, identified by the letter A, indicates the activity of the port (whether it is connected or it is com-
municating).

The sockets for the CFast memory and for the SD memory are located on front of the device. These memories
are installed inside the device, behind a transparent plastic cover.
8.8 Reset button
The reset button allows the computer to be restarted immediately.

9 Installation
During installation of the FLXMOD MST S4 computer, falls and violent shocks must be
avoided which could compromise the smooth operation.
Avoid touching the input / output connectors on the computer panel directly unless you are
equipped with suitable static electricity protection equipment; any discharges on the con-
nectors could damage the appliance.
Always carry out all electrical connections when the equipment is switched off: this will pre-
vent damage to the computer and danger to the operator (exceptions to connections to the
USB ports are possible).
Always make sure that all the devices connected to the MST S4 have an efficient grounding
(if foreseen by the device). Failure to follow this precaution could result in damage to the
computer and danger to the operator.
Do not position the device so that it is difficult to disconnect the wiring connected to it.
9.1 Assembly
The MST S4 module, like all modules belonging to the FlxMod system, are fixed to a DIN rail by means of a
spring-loaded coupling system.
In the FlxMod system, functional grounding (FE) is simply performed by hooking the module to the DIN rail.
Below is an example image:

9.2 Environmental requirements
In order for the system to operate properly, the MST S4 module must remain within the temperature limits in-
dicated in the specifications. This means that, inside the electrical cabined where the module is installed, there
should be a suited cooling system in order to keep the temperature within the correct limits.
9.3 Electrical wiring
The main connections for the MST S4 operation are the power supply and the earth; make these connections
following the instructions on polarity, conductors and connectors stated in the chapter “Connections”. Before
switching on the computer, make sure that the mains voltage is within the parameters indicated in the
specifications.
The device connection to the peripheral units is simplified by the use of standard computer connectors; this
means that all standard peripheral for personal computers can be connected by means of the cable supplied
with them or by means of commercial cables easily found on the market.
For connections to non-standard devices, such as inverters or other that require particular combinations of sig-
nals and cable lengths, it is possible to make them following the instructions stated in the chapter “Connec-
tions”.

10 Use
10.1 CFast card
The CFast card of the MST S4 module replaces the traditional hard disk, thus ensuring better shock tolerance
and longer life of the device, also in case of continuous working cycles.
The flash card positioning and its easy removal/insertion allow quick replacement, both in case of failure or soft-
ware off-line upgrade.
In order to avoid damages to the computer and/or CFast card loss of data, always switch off
the module MST S4 before replacing the flash card.
10.2 Micro SD card
The micro SD card of the MST S4 module replaces the traditional hard disk, thus ensuring better resistance to
shocks and longer life of the device.
The micro SD card positioning and their easy removal/insertion allow quick replacement, both in case of failure
or software off-line upgrade.
In order to avoid damages to the computer and/or micro SD card loss of data, always switch
off the module MST S4 before replacing the micro SD cards.

10.3 Priority of the start-up devices
A boot device is the CFast card or USB flash disk, or other mass storage on which the operating system (for
example Windows) is stored by which the computer boots.
By default, the search for the operating system takes place first in the CFast, then in a possible USB flash disk.
The first device among these, which contains the boot information that an operating system needs, is used.
Therefore, if you want to boot the computer in a different sequence, you need to remove the other possible boot
devices (eg by ejecting the CFast).
For the BIOS operating mode belonging to the MST S4 module, the boot sequence automatically adapts to the
number or serial number variations of the boot devices; in fact, new devices, that is not present when the com-
puter was first turned on, are inserted as last in the start sequence.

11 Ordinary maintenance
11.1 Clock battery replacement
The backup battery in the MST S4 module powers the RTC circuit (real-time clock). The RTC is a real-time
clock which remains active even when the device is off and constantly updates the date and time. According
to the ambient temperature and to the computer use, the battery can have a markedly different duration, start-
ing from the MST S4 production date.
When the user realizes that the battery is exhausted, it can replace it in a few simple steps:
• STEP 1

Gently remove the battery with pliers, being careful not to drop
it into the device
Insert the battery in the housing indicated in the figure, paying
attention to the polarity and then to the direction in which the
battery is inserted. See the following images:

the pole (+) is facing the computer heatsink
Battery side with negative polarity (-):

• STEP 3
Once the new battery has been correctly inserted, repeat each operation described in every part inversely.
Then manually update the date and time using the operating system.

12 Appendices
12.1 Appendix I: CMOS Setup parameters
In the MST S4 module, the CMOS Setup parameters are stored in the BIOS and are password protected to
guarantee operation.
In the event that a loss of the CMOS setup parameters occurs, for example due to running out of the buffer
battery, these will automatically reset when the device is turned back on, while the date and time will have to
be updated manually using the operating system.
If necessary, the CMOS setup password can be requested from the service department.
