Select CALL from the menu bar and select Disconnect. The usual defaults are 2400 baud, 7 data bits, no parity, 2 stop bits and no handshake. ![]() See the instruction manual for the balance. Set the parameters to match the parameters in the balance. (Which COM port appears will depend on the setting in the previous step.) In the next screen click on the twirl down for the "Connect using" box and select the COM port your computer uses.Ĭlick OK and the COMx properties box will be displayed. ![]() You will probably want to save the setup for future use. Open the program and enter a name for the connection. The following assumptions are made for the purpose of explanation.Ħ. To set up Hyper Terminal for use with an Ohaus balance, perform the following steps. Q: How do I use Hyperterminal to check communications?Ī: Hyper Terminal is a Terminal program that is bundled with Windows. (You do not need an arduino for it to work.) that will listen to the configured serial port. You can download this for your platform and open the application and go to tools serial monitor. Now would there be a logical reason why only part of this data is sent(or received)? i pushed the button 6 times in succesion, getting results like ? or 2? or ?.04?A? or ?KG these results combined show me that it tries sending 2.04KG, the weight. If i push the button i get "random data" if i use a text mode on an application, this data translates into question marks and parts of the weight. I have found that the "print button" on the scales has the same functionality as the "P" command. the same happens with arduino, and sending the "P" command gives no data back. Using Hyper terminal gives me the below result. Model is OHAUAS defender 5000 series - T51P ![]() When i do listen on the port though, the echo "LP" > com1 command gives an unavaible error, so sending the command works in cmd.ĭoes anyone have any knowledge on a simple way to test a send and receive on a com port? A small C# application that listens to this port seems to be continuously receive Hexadecimal numbers (2 digits then an enter), however sending a command through this application doesn't give readable results. Is there a way to test this? i tried the command line echo "LP" > com1 but this does nothing. if we connect this to a PC we should be able to get the weight on the computer by sending a command to it. We have a OHAUAS defender 5000 series model T51P Weighting scales with a COM port.
