1.2 Interfaces and I/Os
All eVision² inputs and outputs are protected against electrical surges and short circuits.
1.3 Advanced Programming Possibilities
eVision² runs the Linux operating system on an ARM Cortex A-8 processor. The unit can beprogrammed using CODESYS, a common IEC 61131-3 programming system that allowsdeveloping applications with a PC running Microsoft Windows®. In addition to the possibility towrite applications in Structured Text, several editors are supported, including the Instruction ListEditor, the Sequential Function Chart Editor and the Function Block Diagram Editor. CODESYSproduces native machine code for the main processor of eVision².New software can be uploaded to eVision² either via Ethernet or USB flash memory drives.
HY-eVision² 7.0 is equipped with a 34 pin TYCO Super Seal connector. Figure 1 shows theconnector layout on the backside of the device. Section 2.1 defines the pin out of the connector,while section 8.1 discusses the mating connector and its manufacturer part numbers. The detaileddescription of each signal is presented in section 2.1.

Connector Pin Number FunctionPin 18 Terminal 15 Input
Functional description
Terminal 15 is used to switch the power supply of the eVision² device.
Power on/off sequence
Possible power on/off sequences of the device are shown in Figure 3. The device starts booting ifterminal 15 is pulled to high (typically BAT+).
When setting terminal 15 to low, there are two scenarios:
If terminal 15 is set to low before the flash memory is mounted writeable, the device willswitch off immediately (Case B).
If terminal 15 is set to low after mounting the flash memory writeable, the application willbe responsible to save all data to flash and power off the device via software (Case A).This is necessary to ensure the data integrity before power off.

3 A Mount Flash writable4 A Application start
5 A Terminal 15 low Application specific shutdown starts
6 A Application specific shutdown finished, eVision² power off2 B Terminal 15 low Flash is not writeable yet immediate power off
For systems with a main power switch (not permanent supplied, switched BAT+ pin)terminal 15 must be set to low for sufficient time to allow the device to perform a propershutdown before it can be disconnected from the battery without corrupting data. Theshutdown sequence has to be implemented in the application software.

The 10/100 Mbit full duplex Ethernet port is compliant with IEEE 802.3. However, there is nostandard Ethernet socket provided, the Ethernet signals are located on the main connector.Be sure to use appropriate cabling according to the Ethernet standard; at least Ethernet CAT5cable for 100 Mbit/s and Ethernet CAT3 cable for 10 Mbit/s transmission speed. In a noisyenvironment it is recommended to use shielded cables. In this case, Pin Ethernet Shield has to beconnected to the shield of the Ethernet cable.

The USB Host interface is compliant with the USB 2.0 standard.Be sure to use an appropriate cable for the USB connection. For the USB data lines a twisted pairconnection has to be used. In a noisy environment the data line pair should be shielded separately.In this case, connect the cable shielding to USB Ground.If the USB interface is used to connect a removable device, provide a connector compliant to theUSB standard. This ensures that the pins of the USB interface are connected in the right order(first shield, then GND, then Vbus, then the data lines), thus preventing the interface from gettingdamaged.

Note 1: The maximum cable length depends on the type of cable used, the number of connectors between
the devices, the environment the cable is installed as well as the USB transmission speed modeused. As a rule of thumb, each connector pair decreases the maximum cable length by 0.5 meters ifa USB conform connector is used. If an arbitrary connector is used, the length penalty will be bigger.
Note 2: Please note that an USB high speed (HS) connection is more sensitive than an USB full speed (FS)or low speed (LS) connection. So the maximum possible cable length also depends on the kind ofperipheral connected to the USB interface.

Note 1: Due to possible high currents in the wiring harness the individual ground potential of control units
may differ up to several volts. This difference will appear also between a transmitting and receivingcontrol unit as common mode voltage and does not influence the differential bus signal as long as itis within the common mode limits.
Note 2: The arbitration process will allow 1 Mbit/s operation only in small networks and reduced wire length. As example a so called “private CAN”, a short point to point connection (less than 10 m) betweenonly two nodes can be operated at 1 Mbit/s.
Note 3: For typical network size and topology (network with stub wires) and more than two nodes thepractical limit is 500 kbit/s.
The eVision² is able to handle PAL B/G/H/I/D (standard PAL) and NTSC-M (standard NTSC)compatible composite video signals (CVBS or FBAS). The inputs support automatic configurationand automatic gain control. One of the two video sources can be displayed at a time.

The eVision² includes a real-time clock with backup power system. When the eVision² is connectedto the vehicle’s battery via the BAT+ pin, the real-time clock is supplied by the vehicles batteryregardless if the device is operational or in power-off mode. If BAT+ is disconnected, the real-timeclock is supplied by an internal super-capacitor. The super-capacitor provides approximately 14days of backup time if fully charged. It is charged if the BAT+ pin is connected to the vehiclesbattery. If the device is switched on, the capacitor is fully charged in 2 hours. If the device is inpower off mode, only trickle charging is performed. Trickle charging an empty super capacitortakes at least 72 hours.

Pillowing height can be determined as follows:
Use A and B as reference points and calculatepillowing height hP using the followingequation:
The touchscreen is a sensitive component. It is constructed from two layers of material (a thinplastic foil and a glass sheet) with a small space between them. When pushing on the surface (thethin plastic foil) the two layers are pressed into contact and a touch event is registered.To prevent damage of the touchscreen protect it from excessive mechanical forces (e.g. hit) andenvironmental loads. Excessive mechanical force may result in breakage of the touch glass.
Do not use hard, sharp or spiky objects to operate the touchscreen as this will result in damage ofthe surface layer and render the touchscreen inoperable.
The touchscreen surface shall be kept clean of abrasive particles (e.g. sand, metal swarf) at anytime. Operation of the touchscreen with abrasive particles on it will result in roughening of thesurface. Over time this affects visibility of the display as it will render the screen dull and fuzzy. Forthe same reason do not use paper towels or paper tissues for cleaning as they contain wood fibersand will scratch the plastic surface.
The touchscreen is calibrated during production of HY-eVision² 7.0. Depending on theenvironmental conditions in which HY-eVision² 7.0 is operated recalibration of the touchscreenmay be needed from time to time.
6.8 CleaningFor cleaning of the touchscreen follow the following instructions:
Use a soft, lint-free cloth (e.g. soft cotton or micro fiber cloth).
The cloth may be used dry, or lightly dampened (not wet) with water.
Wipe the surface gently, do not use excessive force.
If needed a mild, pH neutral cleaner can be used.
Never use acidic or alkaline cleaners, or organic chemicals such as paint thinner, acetone,toluene, xylene, propyl alcohol, isopropyl alcohol or kerosene.
Never apply cleaner directly to touch panel surface. In case cleaner is spilled onto thetouchscreen soak it up immediately with absorbent cloth.
Use of inappropriate cleaners or cleaning methods can result in optical derogation of thetouchscreen and / or affect functionality.
HY-eVision² 7.0 housing is intended for both panel mounting and stand-alone mounting. Figure 9and Figure 10 show the housing with detailed dimensions. The housing assembled with mountingbracket is shown in Figure 12. The required mounting space and panel cut-out dimensions aregiven in Figure 13.
7.1 Housing dimensions
Figure 9: HY-eVision² 7.0 housing backside view with dimensions
Device has to be mounted in such a way that the pressure compensation element and theconnectors for the wiring harness are not exposed to direct splashing water.
Device has to be mounted in such a way that its connectors are freestanding in order toallow its counterparts to be connected without obstructions.
7.2.2 Cable harness
Cable harness needs to be fixed mechanically in the mounting position of the device toavoid mechanical stress to the connectors and possible failure of the connection caused byvibrations or weight of the cable harness.
Cable harness needs to be fixed in such a way that, in case of an excitation, the cableharness is in phase with the device (e.g. at the fixing point of device).
7.2.3 General advice
It has to be assured that no water can leak into the device through the wiring harness.Please refer to chapter 8 on page 46 and the documents from the connector manufacturer
referenced for detailed information on this topic.
The pressure compensation element as well as the sealing must not be submerged inwater.
7.2.4 Mounting position and alignment
Mounting position and alignment of the device shall be chosen in such way that:
The device is protected against environmental loads such as excessive sunlight, rain, hailand snow.
Water can easily drain off (no standing water on any surfaces of the device).
The device is protected from excessive mechanical forces (e.g. hit) which could lead to
break of glass or damage of the housing. Overheating of the device is prevented by allowing natural convection and ensuringprotection against external heat sources.
The surrounding temperature is equal on (and acts equally to) all sides of the device.Elevated temperatures on the backside of the housing may lead to temporary fogging of thefront glass.
