4 Product description

The POSYC is a personal computer based on Intel®64 architecture designed primarily to facilitate human-ma-

chine interfacing (HMI) in an industrial environment, but its characteristics make it suitable also for different us-

es, such as information terminals and automation systems in gender.

The user interface mainly uses a flat color display and a touch screen pointing system integrated into the prod-

uct.

The 15-inch LED-illuminated TFT liquid crystal display with a diagonal dimension of 15" offers a considerable

display area, great brightness, color brilliance and a good viewing angle.

The touch screen system offers features of robustness and ease of use, difficult to obtain with other common

pointing devices such as mouse, track-ball and mouse pad.

Being completely integrated into the appliance, it is particularly suitable even in industrial applications that re-

quire resistance to external agents such as dust, humidity, water, oils, etc., which would be harmful for standard

devices.

Since it is sufficient to exert a slight pressure with a finger on its surface to make an immediate pointing, this

system is the main “User Friendly” feature of the POSYC computer.

In order to meet the most different interfacing needs, POSYC nevertheless provides the possibility to connect

also standard input / output devices, such as keyboard, mouse, track-ball, monitor, etc.

In its minimum configuration, the POSYC can communicate with the outside world via 1 standard RS232 serial

port and 1 RS485 port; it also offers 4 standard USB 3.0 ports, 2 IP65 USB 2.0 ports on the front, 2 10/100 /

1000Mb Ethernet ports, 1 HDMI port and 1 DVI-D port.

Depending on the version, a profibus card may be available in addition to the basic hardware of the POSYC

430X series.

The POSYC calculation capability is given by the Intel® Celeron ™ N3160 processor, Quad-Core, 1.6GHz with

4GB SDRAM DDR3L memory.

The storage of data and programs on non-volatile support is entrusted to a 32GB CFast card (high-speed flash

memory). The position of the device inside the POSYC is such that it can be extracted without opening it. The

main advantage of the CFast card is its exceptional resistance to accidental shocks and vibrations.

The new design makes it particularly attractive even for non-industrial applications.

6.5 Ethernet ports

There are two 10/100/1000 Mbps Ethernet ports that use standard RJ45 Ethernet connectors.

The two RJ45 connectors on the POSYC are shown below:

Each of the two Ethernet ports has two LEDs. The first, distinguished by the letter A, indicates the communi-

cation speed of the port involved. It is a two-color LED (green / orange); according to the speed at which the

Ethernet port is communicating, the LED takes on a different color. The second, yellow, marked by the letter

B, indicates the state of activity of the gate itself, or if the gate is connected or if it is communicating.

6.5.1 LED behavior of communication speed signaling

Below is a table that summarizes the possible speed states of Ethernet port:

7 Installation

During installation of the POSYC 430X 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.

Since the front panel integrates the touch screen sensor, violent blows in addition to dam-

aging it irreparably could bring to light cut-glass shards, therefore dangerous for the opera-

tor.

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 POSYC 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.

7.1 Panel mounting

The POSYC can be mounted on the panel by preparing the recommended cut on a panel that is strong enough

to support its weight and to remain flat once the computer is fixed. A lack of flatness or a wrinkled surface of

3.2μm can compromise the effectiveness of the round gasket installed in the POSYC frame.

For fixing use 4 stainless steel 4xM5x12mm screws, tightened to 3 Nm (not supplied); depth of threaded holes

in the 10mm frame.

Rev. 1.02 24

POSYC 4301/4302/4303 series industrial PCs Installation, use and maintenance manual - EN

7.2 Assembly in dedicated body

The POSYC can be mounted in one of the two dedicated aluminum frames (for the order codes see specific

chapter).

Both have a predisposition for the attachment to a support arm with standard dimensions and holes "VESA

MIS-D, 100, T". To fix the body to the arm, then use four M4x10mm steel screws (not supplied).

Prepare the POSYC by screwing the MA117784 spacers (supplied with the computer) into the four holes at the

corners of the frame. A 6mm spanner wrench is required for tightening.

Slip the POSYC to the body by sliding the spacers in the appropriate seats of the same and secure it by screw-

ing the two M5x60mm screws (MF300543 supplied together with the body) into the intermediate holes, tight-

ened to 3 Nm. To hold it tight, screw the four M5x10mm screws (MF300168 supplied together with the body)

into the holes in the corners, tightened to 3 Nm.

Then, to inspect the connections and the CFast without completely releasing the computer from the body, re-

move the four screws at the corners and take advantage of the sliding of the spacers.

Example of assembly in a dedicated body with a push-button panel

7.3 Environmental requirements

The POSYC is designed to be placed in a container that gives it protection from water and dust that could dam-

age it.

The internal cooling of the POSYC takes place through the air sucked at the rear by a high-speed fan; in order

for the system to work properly it must remain within the room temperature limits given in the specifications. All

this implies that within the panel that will surround the POSYC, there must be suitable cooling systems to keep

the temperature within the accepted limits.

The dedicated bodies are designed not to exceed the maximum temperature accepted by the POSYC and

therefore do not require any other precautions.

7.4 Electrical connections

The essential connections for POSYC operation are power and land; make these two connections by following

the polarity, conductors and connectors indicated in the “Connections” chapter. Before switching on the appli-

ance, check that the power supply voltage is within the parameters specified.

Rev. 1.02 26

POSYC 4301/4302/4303 series industrial PCs Installation, use and maintenance manual - EN

The connection of POSYC to peripherals is simplified by the use of standard computer connectors; this means

that all standard peripherals for personal computers can be connected via the cable supplied with them or in

any case with easily available commercial cables.

In the case of connection of non-standard devices for personal computers such as inverters or other and you

need combinations of signals and lengths of customized cables, you can make yourself what you need based

on the information provided in the chapter “Connections”.

The following are some recommendations on how to make the cabling for serial communication.

7.4.1 Wiring standard RS232 serial ports

This type of connection can only connect two devices and the wiring can be made with a variable number of

conductors depending on the needs.

According to the specifications of the RS232 standard, the maximum cable length is 15mt at a transmission

speed of 20kbps. Please note that the cable length is inversely proportional to the communication speed.

The pairs of twisted conductors are normally used to carry a given signal and its reference (for example TD and

GND); the GND connection between the devices is essential for correct operation.

It is good practice to connect the shield of the cable used only at one end (preferably from

the computer side) to avoid differences in potential between the two devices creating a cur-

rent circulation on the wiring screen, thus introducing communication disturbances; in some

applications it is however possible to connect to both ends. The non-connection of the

screen to the ground instead (disconnected from both ends) nullifies the function of the

screen itself.

7.4.2 RS485 serial ports wiring

The typical use of RS485 ports is in multipoint configuration, or more devices connected to each other; this type

of connection exploits a single pair of conductors and from this it follows that the communication is of the half-

duplex type.

Through the RS485 serial ports, up to 32 devices (including the master) can be connected in a single section,

offering good noise immunity and a maximum transmission speed.

According to the specifications of the RS485 standard the maximum length of the section is 1200mt at a max-

imum transmission speed of 100kbps. Please note that the length of the section is inversely proportional to the

communication speed.

POSYC 4301/4302/4303 series industrial PCs Installation, use and maintenance manual - EN

Through appropriate repeater devices (maximum 9) it is possible to extend the connection and connect up to

126 devices.

For correct operation it is necessary to use a suitable cable, terminating it appropriately. The

termination consists in connecting at the beginning and at the end of the section of the re-

sistors with a value of 120ohm; for the beginning and end of the section, the master and the

most remote slave are considered respectively (called 1 and 4 in the figure below). The

length of the cable connecting the intermediate line (called 2 and 3 in the figure below) must

be as short as possible (in any case below 1mt), otherwise the signal quality will be lost. The

RS485 serial ports of the POSYC do not have the termination resistors connected internally.

Example of RS485 wiring

An additional conductor with respect to the couple indispensable to the communication that connects the mass-

es with each other significantly reduces the probability of failure of the non-isolated serial ports that could be

part of equipment with very different ground references.

It is good practice to ground the shield of the cable used only at one end (preferentially from

the computer side) to avoid that potential differences between the two devices create a cur-

rent circulation on the wiring screen, thus introducing communication disturbances; in some

applications it is however possible to connect to both ends. The non-connection of the

screen to the ground instead (disconnected from both ends) nullifies the function of the

screen itself.

7.4.3 Profibus DP port wiring

Like the RS485 port, up to 32 devices (including the master) can be connected to a single line via the Profibus

DP port, offering good noise immunity and a maximum transmission speed.

According to the specifications of the Profibus standard, the maximum length of the section is 1200mt at a max-

imum transmission rate of 93.75Kbps. It should be noted that the length of the section is inversely proportional

to the communication speed and that at the maximum transmission speed of the gate, or 12 Mbps, the length

of the section is 100 meters.

126 devices.

For correct operation it is necessary to use a suitable cable, terminating it appropriately. The

termination consists in connecting at the beginning and at the end of the section of resistors

with a defined ohmic value (see figure below); for the beginning and end of the section, the

master and the most remote slave are considered respectively (called 1 and 4 in the figure

below). The length of the cable connecting the intermediate line (called 2 and 3 in the figure

below) must be as short as possible (in any case below 1mt), otherwise the signal quality

8 Use

8.1 Touch screen

The use of the POSYC computer is very similar to a normal desktop computer; the only substantial difference

is the touch screen pointing device which, however, allows an even more intuitive use of the computer.

CAUTION

Operate the touch screen sensor only with your fingers or soft and not sharp objects, other-

wise you will damage it.

ATTENTION

Utilisez le capteur d'écran tactile uniquement avec vos doigts ou des objets mous et non

tranchants, sinon vous risqueriez de l'endommager.

To operate the touch screen, a slight pressure is sufficient (this has the appearance of any glass plate) to com-

mand the operating system pointer to move below the area where the pressure has been exerted. Depending

on the software settings, the touch screen simulates dragging, clicking, double clicking and right mouse button.

Refer to the software manual for further details.

8.2 Front USB ports

The front USB ports have been designed to connect temporary devices such as keyboards and flash disks; the

seat of the USB connectors ensures the IP65 degree of protection towards the inside of the computer both in

use and in rest conditions.

CAUTION

To avoid oxidation damage to the contacts of the front USB connectors, once the use is fin-

ished protect them again with the special cap to protect them from dust and dirt. The cap

does not guarantee IP65 protection to the USB connectors.

Rev. 1.02 31

POSYC 4301/4302/4303 series industrial PCs Installation, use and maintenance manual - EN

ATTENTION

Pour éviter que les contacts des connecteurs USB situés à l'avant ne soient endommagés

par l'oxydation, une fois l'utilisation terminée, protégez-les à nouveau avec le capuchon

spécial pour les protéger de la poussière et de la saleté. Le capot ne garantit pas la protec-

tion IP65 des connecteurs USB.

8.3 CFast card

The POSYC CFast cards replace the traditional hard disk giving it more robustness to shocks and increasing

its useful life even in the presence of continuous work cycles.

The positioning of the flash card and the simplicity of extraction / insertion allows a quick replacement both in

case of failure and off-line software update.

The operating system (Windows 10IOT Enterprise Entry) and an empty NTFS partition created to contain any

future specific software or data are stored on the supplied flash card.

CAUTION

To avoid computer failure and/or data loss to the CFast card, the replacement of the same

must be done exclusively at POSYC turned off.

ATTENTION

Pour éviter toute panne d'ordinateur et / ou toute perte de données sur la carte CFast, son

remplacement doit être effectué exclusivement à POSYC off.

8.4 Boot devices priority

The boot device refers to the mass memories on which the operating system is stored (for example Windows,

Linux, etc.) as CFast card and USB flash disk.

By default, POSYC searches for the operating system boot information in the mass memory used for the pre-

vious boot, such as CFast, and if it is found, the boot device is not changed; in contrast, another is sought on

other ports, such as USB.

This is a behavior that depends on the working method of the UEFI BIOS.

In normal working conditions it is not necessary, and also not recommended for safety reasons, to start the

POSYC from devices other than the supplied CFast.

Rev. 1.02 32

POSYC 4301/4302/4303 series industrial PCs Installation, use and maintenance manual - EN

For exceptional needs like backup, restore, BIOS update, etc. it is possible to start POSYC via USB flash disk

(non UEFI) without having to access the CMOS setup parameters that are password protected for security rea-

sons.

To start POSYC via USB flash disk for activities that do not need to access the CFast (for example BIOS up-

date), to POSYC off extract the CFast from its housing, insert the USB flash disk containing the operating sys-

tem, turn on the POSYC and run the necessary activities; at the end, turn off the POSYC, remove the USB

flash disk and switch on the POSYC without CFast: an UEFI shell will be started. Switch off the POSYC again

and insert the CFast in its housing; when it is switched on, POSYC will start from CFast.

To start POSYC via USB flash disk for activities that need access to the CFast (for example backup or restore),

to POSYC off extract the CFast from its housing, insert the USB flash disk containing the operating system,

turn on the POSYC and let it start from the USB flash drive. Turn off the POSYC, insert the CFast in its housing,

turn on the POSYC and perform the necessary activities; at the end, turn off the POSYC, take out the USB

flash disk and the CFast from its housing. Restart the POSYC: an UEFI shell will be started. Switch off the PO-

SYC again and insert the CFast in its housing; when it is switched on, POSYC will start from CFast.

In some special situations, the Windows 10 IOT operating system may not be able to regularly restart with the

default settings of the Cmos-Setup and therefore it is necessary to modify them by accessing them using the

STECH password and setting, in the Boot page, the New Boot Option Policy item in Place First instead of

Default.

Be careful not to modify any other parameter, otherwise the device will not work.

9 Ordinary maintenance

9.1 Cleaning the touch screen sensor

The cleaning of the touch-screen sensor must take place rather frequently to avoid the stratification of the dirt

derived from the hands or from materials that were accidentally in contact with its surface and to maintain the

best possible visibility of the display.

If necessary, the front of the device (keyboard and viewing window) can be cleaned with a very soft cleaning

cloth (recommended in microfibre) dampened with water or cleaning solution for display.

9.2 Replacing the clock battery

The replacement of the internal clock battery, in addition to ensuring the maintenance of the same, is useful

not to lose the settings of the CMOS Setup (basic information for the operation of the computer).

Depending on the climate and how the computer is used, this can have a very variable duration starting from

the POSYC production date.

It is therefore suggested to carry out the preventive battery replacement at least every 2 years taking care to

always use the exact model (3V lithium battery - CR2032).

To replace it, simply remove the back cover of the computer with the power switched off and replace the battery

(shown in the figure) with a new one. If the existing battery is not completely discharged, performing the re-

placement operation in a few seconds, it will not be necessary to correct date / time and settings of the CMOS

Setup.

10 Appendices

10.1 Appendix I: Parameters of the CMOS Setup

In the POSYC 430X series industrial PCs, the CMOS Setup parameters are stored in the BIOS to guarantee

operation.

In the event that there is a loss of memory of the CMOS Setup, for example, after the backup battery has been

used up, these will automatically reset when the POSYC starts up except for the date and time which can be

reset using the operating system.

If the parameters are to be changed incorrectly, they can be reset using the “Load UEFI Defaults” function in

the “Exit” menu of the CMOS Setup.
