Library lpos_usb_vfd.dll uses an additional library LPOS_VFD_LCD.dll. The driver is used in configurations based on the platform "1C: Enterprise 8.0" and above.

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

Question: We are interested in the products you display to the customer POSUA LPOS-II-VFD-2029D.
Unfortunately, there are doubts whether it suits us.
Please can  you send instructions for use of the display, it is important to understand what Pin out at the power connector.
Answer:  To power customer display there  are several options:
With the interface cable RS232 - through 9-pin connector second DB9 (if the system supplies  power through the 9-th output).
With a special interface cable RS232 - this cable is output to the bar food, which is installed in place caps PCI slots (described in the attached documentation) - in this case, DP is powered by BP in the case of the computer.
From an external PSU - connects directly to the customer display.
Standard customer display is available as described in the second version.

Question: Are there any 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 a processing service PD, to connect to the 1C version 8.0 and above.

Question: How do I register the library DLL LPOS_VFD_LCD.dll version 1.0.2.0?
Answer: The library and demo program uses a static import of  the required functions. If you can not use this method of loading the library, you should download the library using the Load Library (dynamic imports). After loading the library it’s necessary  to determine the address  of the used library functions using GetProcAddress (the names of functions, the names are listed in the file lpos_vfd_lcd.pas)

Question: Tell me please, is there a possibility of the customer display VFD (USB) through the com port emulation?
Answer: No, the customer display VFD USB only works in HID mode. For communication with AP you can use *. library (lpos_vfd_lcd_lib).
Question: I am writing process, and therefore the question: in the method "Connect" and  to put the line on the customer display " could you specify what parameters should be monitored. Or maybe there is an example of writing in 1C for the parametersf " Array ofmeaning" and "Array of lines "
Answer: We plug-in components in 1C 8.0 as follows:
To load the Internal Component ("lpos_usb_vfd.dll");
Component = new ("AddIn.lpos_usb_vfd_extension");
Array of meanings= new Array ();
Code page= 12;
Array of meanings Add  (Code page);
If (Komponent. Connect Array of meanings (IDUof device ) <> True) Then
     Komponent.Receive Mistake  (Field of input 4);
    Field of input 5 = "0";
Otherwise
    Field of input 4 = "OK";
     Field of input 5 = IDU of device;
END IF

lines output:
Array of lines= new Array ();
Structure Str1 = New Structure;
Structure Str2 = New Structure;
Structure Str1.Insert ("Text",Array of input 1);
Structure Str2. Insert ("Text", Array of input 2);
Structure Str1. Insert (Running Line, Flag1) / / if the flag
set, the text in the row is scrolled
StructurStr2. Insert (Running Line, Flag 2);
Array of lines. Add (Structure Str1);
 Array of lines. Add (Structure Str2);
If (Komponent.To put the line of the Customer Display (IDUof device, Array of lines) <> True) Then
     Komponent. Receive mistake (Field of input4);
Otherwise
    Field of input4 = "OK";
