Cdc Serial Port Scale
If you really want to understand how your Weight Scale application works with your Weight Scale then get a Y cable and install it between the PC and the connector from the weight scale into the PC. The PC is considered DTE or Data Terminal Equipment. The Weight Scale, unless a crossover cable is being used with it, would be considered DCE or Data Communications Equipment. You can download this VB. Atheros Ar9271 Wireless Driver Windows 8. Net App and run two copies of it as the tope image below shows on the second PC.
Quick Start Guide for FRDM-KL26Z The Freescale Freedom development platform is a set of software. CDC Serial Port”. Using the Virtual Serial Port. Connect a weighing scale with RS232 to a computer with USB, no longer do you need a serial port to connect a weighing scale to a PC.
And monitor the data sent from the PC (the top PC below) with the weight scale app on it and monitor the data returned by the weight scale app. However from the pins being used on the cable end facing the second PC it's possible that signal ground will need to be Y'd out from it so each com port on the second PC has that connection for ground reference. For DB9 connector signal ground is pin 5. For DB 25 connector you still access Pins 2 and 3 but for signal ground you use pin 7. It's possible the data sent to and receive from the Weight Scale will not be human readable. However if you select some button to retrieve data from the machine using its app you should be able to monitor that data and determine some reference as to how the Weight Scales app is altering it for a readout.
As well as monitoring what is sent to the weight scale machine to retrieve specific data. Below is an image of that app which I downloaded, brought up in Visual Studio and ran. But since I have no Com Ports on my PC it does nothing of course. Also is an image of a split DB9 cable showing for sniffing which pins to use. If you run the app then you will have to alter the Baud Rate, Parity, Data Bits and Stop Bits until the data being received appears valid in some form. La vida loca. I have changed baud rate, parity etc, but it showing the resulting value in listbox as below in two line (not changing even I am putting different values on the weight board) You will not be able to make sense of the data when you try to view it as ASCII text.
Read the data as bytes and display as hex and you might be able to hit on the correct communications setup and possibly even interpret the data. You do not need additional hardware or software in order to see the response - VB can do that quite adequately, provided you do not try to force the data into ASCII text.
Hi, I am new to comport and it's programming. I want to make an application for Scale / Weight machine in our Industry where the trucks are supplying woods to us. I need to make an application which receive data from scale machine through comport(serial) show me the current weight on the board to my desktop application then I will save it in my database.
Kindly send me a complete code just to receive data to the textbox from scale / weight machine. Thanks in advance.
You are prepared to pay more then 200.000 dollars for that interface? Thanks to all valuable who responded me. Is this application will receive the data from the scale machine? OK, I designed the application as you shown started, Only one port is available in the cboPort changed the baud rate one by one clicked the SET button and Open Port for each.
But no response, although after closing your application i have ran our scale programe installed before here is working well. The textboxes is not showing the weight showing on my terminal supplied with our scale machine. Thanks to all valuable who responded me.

The textboxes is not showing the weight showing on my terminal supplied with our scale machine. This isn't magic. If you don't know anything about serial communications then you will not receive results expected.
If you don't know how to use serial communications to interface with the weight machine then you will not receive results expected. If you don't know how to contact the weight machine using serial communications and then display whatever is returned by the weight machine according to whatever it returns then you will not receive results expected.
Denon Avc A1d User Manual. If you don't know anything other than how to type some words that you hope will do something into a program then again you will not receive results expected. You've already been asked to contact whoever makes the weight machine so that you can get documentation from them on how to communicate with their weight machine. Apparently you have avoided that altogether. Which leaves you thoughtless on what to do.
