Frequently asked questions on the customer display LPOS-II-VFD

Question: We are interested in creating or Customer Display POSUA LPOS-II-VFD-2029D.
Unfortunately, there are doubts whether it will suit us.
Please can send instructions for use of this display, it is important to understand what a power connector pinout.
Answer:
Power the customer display can be a few options:

1. With the interface cable RS232 - a 9 th pin connector DB9 (if the system provides power via the 9-th output).
2. Using a special interface cable RS232 - this cable has a power output at the bar, which is set in place the plug PCI slots (described in the attached documentation) - in this case the DP is powered by a PSU in the computer system unit.
3. From an external power supply - connects directly to a customer display.

Standard customer display is available as described in the second version. 

Question: Are drivers and processing services to connect the customer display "POSUA VFD USB" to "1C: Trade Management"?
Answer: The driver is implemented as an external component "1C: Enterprise" (lpos_usb_vfd.dll).
Library lpos_usb_vfd.dll uses an additional library lpos_vfd_lcd.dll,
it should be in the same directory as the display driver.
Also developed Processing Service JP, to connect to the 1C version 8.0 and above.

Question: As registered library DLL LPOS_VFD_LCD.dll version 1.0.2.0?
Answer: The library and demo program uses a static import of the necessary functions. If you can not use this method of loading a library, the library should be loaded using the LoadLibrary (dynamic imports). After loading the library to determine the address used by the library functions with GetProcAddress (by name functions whose names are listed in the file lpos_vfd_lcd.pas)

Question: Tell me please, is there any possibility of the Customer Display VFD (USB) through a com port emulation?
Answer: Yes, Available now displays, built on the basis of the microcontroller ATmega32U4, support emulation of COM-port..

Question: Write processing in connection with the question: in the method of "Connect" and "ВывестиСтрокуНаДисплейПокупателя" could not specify what parameters should be monitored. Or may have an example of writing in 1C for the parameters "MassivZnacheny"and "MassivStrok" 
Answer: We connected component in the 1C 8.0 follows:
DownloadTheExternalComponent("lpos_usb_vfd.dll");
Component = New("AddIn.lpos_usb_vfd_extension");
AnArrayOfValues = The New Array();
CodePage = 12;
ArrayOfValues.Add(CodePage);
If (Components.Connect (ArrayOfValues,TheIMUuninterruptable) <> True) Then
Components.GetAnError(InputField4);
FieldInput5 = "0";
Otherwise
InputField4 = "OK";
InputField5 = IMUuninterruptable;
EndIf

/////////////////////////////
OutputLines:
AnArrayOfStrings = NewArray (); 
StructurePage1 = ANewStructure; 
StructurePage2 = NewStructure;
Structure1.VstavitPage(TextInputField1); 
StructureOfThePage2. Insert ("text" input field 2); 
StructurePage1.Embed(Marquee "Checkbox 1) / / if the flag 
set, the text in the row is scrolled
Structure Row2. Embed (Marquee "checkbox2); 
ArrayOfStrings.Add(StructurePage1); 
ArrayOfStrings.Add(Structure Page2); 
If (Component. DisplayDisplayBarBuyer(IMUuninterruptable, SolidLines) <> True) Then 
Components.GetAnError(InputField4); 
Otherwise
Field, enter the 4 = "OK";
End If;

Question: Good afternoon, bought brand display LPOS-II-VFD 2029D USB Версия прошивки 1.33
Unfortunately did not manage to get it to display a scrolling, ie a situation where the entire string is longer than 20 characters. To activate the ticker used by the proposed trial version, written in Delphi, as well as library LPOS_VFD_LCD.dll
Please let me know:
- whether it is a feature of the firmware;
- is there a way to still run the scroll mode, if so, what?
Answer: Customer Display LPOS-II-VFD 2029D USB does not support scrolling. Scroll line can be implemented in control software - software scroll bar and display updated data on the DP.
