View 1 RepliesI have to write a program/application (which I already started in VB.NET 2010) that connects through Panasonic KX-TEM824 PBX machine via RS232 port (cable already connected : COM15/16 depending on USB I connect) and while it's connected to parse(receive) the data from the PBX itself, data that has caller ID, time of call started and ended, duration of the call and etc. I have found some already application on the Internet that does the work but they are free to try after awhile requires to buy or restart the app again. But I assume there's not much to implement on the code side.

I have a digital weighing scale I need to connect to the PC using RS232 communication port. Every time I weigh an object, automatically the result/ weight will display in the the texbox control in Visual Basic Application.I use to receive data via a timer for continuous looping sequence output to a textbox. Things do goes bad, as it flicking all the way. I using a indicator from AD series which read data from load cell of a truck weight bridge. It there's any way to stop this flicking without effecting the continuous loop?
View 3 Repliesi trying to do a app, this app need to take reading from the weighting scale via bluetooth. but my problem now is that the reading from the weighing scale do not come in dynamic way. meaning to say that the value in the textbox will change base on the weight on the weighing scale.

serialport1.write(chr(27) & "T" & chr(13) & chr(10))

I am writing an automation program for an associated research HYPOT tester and one of my current problems is trying to split the data i recieve back from the box.Currently i have two commands i use TD? and SALL? both do the same thing but return different data. TD? when sent to the box will return the test results and of course there is no auto return when test is complete so i have to either set some kinda of timer to get the data after the test is complete or just keep pinging the box tell the test returns with either a pass or fail.my problem is when i ping the box with TD? it returns
"M11,ACW,test results{pass|fail},1.50,10.00,10ms"
What I am trying to do is use a split command to split that line into strings based off "," as my dilimeter. Currently i am useing this set up
dim resultstring as string = main.serialport1.readexisting
dimresultarray as string = split(resultstring, ",",6)
txtTestResult.Text = resultarray(2)
for the most part is does return the test results but other times it will either error out saying that resultarray(2) is out side the index or it will display one of the other strings (acw or 1.50).Is there a more accurate way to do this.I am also printing the full string pulled from the buffer into a text doc as a data log.

View 10 RepliesI want to use IO.ports.serialport to receive ASCII data from an instrument (A Luxmeter for those interested). So far, i've been unable to read any single byte from the instrument using the IO.ports.serialport.A terminal window shows the datastream just fine, and I've used MScommlib to read the data without problems. I just had other problems with the latter, so I thought I'd give this IO.ports.serialport a try.The code runs fine, no errors. It just doesn't receive anything.Bytestoread stays 0 forever.I distilled the code to it's bare essence. What am I missing? Is it something obvious, or did I completely misunderstand the whole concept? (Which is not unlikely..)I did check the obvious, of course: settings, baudrate, cable is connected, instrument is sending, etc.[code]

View 3 RepliesI have blocks of data that arrives from a remote terminal via RS232/COM1 port.
Each block has carriage return at end of the data.
I like to receive the data direcly into EXCEL so it will feel like the remote computer is typing into my EXCEL.
Do I need an interface program outside EXCEL or a MACRO can do the same and how do I do it?
Is there anyway to have the serial data go to keyboard buffer that EXCEL operates from it?
I converted some codes from python to VB 2010. My aim is sending query data to multicast IP and get the response. My query data receiving from device which is connected to my LAN. Also the device responding my query and my PC receiving the responce but at this point the VB program freezing.getting response data and printing to console without freezing.

I have created a program to send and receive data from a serial port, some of the data needs to be stored in certain strings for a export to excel. However the data takes while to to send be sent back. So in order to get the right information in the right strings I have to put pauses in my code. I have added a timer to my form:
On my timer's tick event I have the following code:
Public Sub Timer1_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Timer1.Tick
iTick = iTick + 1
End Sub
I am writing a VB based program which will receive data from a Micrcontroller (programmed in C) via UART. The data that is transmitted from the Microntroller can be displayed on Hyperterminal when I set it up with the correct settings (Baud, Parity etc), so I know that Microcontroller end is working fine. The VB-based program however (written in Visual Studio 2010 Express), does not however receive any data and I always get the TimeOut exception (despite the fact that Microcontroller is sending data via UART, I have an onboard LED to indicate this). Here is the VB code, it is an adapted version from the MSDN library:

I've looked through a lot of snippets online and I see a lot of things similar to
Dim bytes(tcpClient.ReceiveBufferSize) As Byte
networkStream.Read(bytes, 0, CInt(tcpClient.ReceiveBufferSize))
but what I am unsure of when to call such a thing? How do I know when there is data to receive...in visual basic 6 with winsock, there was a specific routine which was called upon data arrival, but I see nothing of the sort for vbNet.
I need to send data via serial and wait for and answer (VB.NET).Right now i'm doing it this way:SerialPort1.Write(sel & Chr(13))Thread.Sleep(50)aaa = SerialPort1.ReadExisting()If i do not thread.sleep, i get nothing, i supose it's because the machine is too fast.
View 1 RepliesI am trying to set up a program that allows you to open multiple COM ports and then select which COM port you send data down. The computer i am using has 18 COM ports. Also on the first code it shows the ports are open they just wont receive anything.
