Bill Acceptor Programming

[abo0badr]

I have just a Microcoin GBA ST2 Bill Acceptor that is interfaced through RS232. The Company gave me an emulator that I can try my Device with, but My problem is I should not use it for my on-design System,

I need help on how to power-up the validator/acceptor using COM Port commands in vb.net,
Since it is disabled when I supply power to the acceptor, only through the Emulator of the company I can make it enabled.

I was wondering if somebody can help with this problem, how to power-up the bill Validator using the .net project..Because my system is created in VB.Net.

Please any one with experience in connecting the bill acceptors please give a comment,,,

Thanks in advance

Maybe read the manual that came with it that explains the initialization procedure? If it is good old RS232, there is likely a combination of lines you need to toggle to reset/poweron the device. In doubt just look at the service manual or schematic.

yeah there is actually a combination of lines like :

Message #	Sent to Validator	Received from validator	Status	Event
1	02 08 10 1F 10 00 03 17	02 08 20 01 00 01 00 03 02 03 2A	IDL	Power Up
2	02 08 11 1F 10 00 03 16	02 08 21 01 10 01 00 03 02 03 3B	IDL	Power Up
3	02 08 10 1F 10 00 03 17	02 08 20 01 10 00 00 03 02 03 3B	IDL

But I don't really know how to figure it out. I tried sending to the validator using the Hyperterminal.exe or Terminal.exe but nothing happens. it is still IDLE or Not Enabled/Standby.

Can you give me some hints or the way I would make it run?

Thank you so much

That is binary data, you cannot send this through hyperterminal, but you might through another proper terminal that supports entering data in hex. Or through VB... The only hints i can give you is read the manual again and again until you understand it.

The problem is I am a newbie in .Net
I only can understand a little. Can you just give me some sample codes that I can start with? or follow?
it is not included in the manual if how am I going to power it up or something like that.

Actually the company gave me an emulator to test the validator, it is running in good condition, but it is in .EXE, and my problem is how am I going to activate or enable it.
when it comes to the detecting of the Bill maybe I can do some work with that, but the main problem for now is how to enable it using those hexadecimal codes.

 

[Herman]

You don't have to enable anything just send those 8 bytes over at the correct baud rate.

You don't have to enable anything just send those 8 bytes over at the correct baud rate.

just like that? I send them and it will power up? but how am I going to send a HEX??I have not yet tried to use sending over the COM port..Just the receiving part

 

[abo0badr]

I tried to make a program that will send the command lines to the validator but it does not do anything, maybe my code is wrong? can you please just comment on my code if what is wrong there? Thanks. here is my code

Public Class Form1    Dim WithEvents myComPort As New System.IO.Ports.SerialPort
    Dim counter As Integer




    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        counter = 0
        If Not myComPort.IsOpen Then
            Try
                myComPort.BaudRate = 9600
                myComPort.PortName = "COM2"

                myComPort.Open()




            Catch ex As Exception
