Today I will show you how to use Virtual Terminal and Serial Port in Proteus ISIS.Virtual Terminal is a tool in Proteus,
which is used to view data coming from Serial Port (DB9) and also used
to send the data to the Serial Port.
In windows XP, there’s a built in tool named Hyper Terminal, which is
also used for the same purpose but in windows 7 there’s no such tool so
for windows 7 users this virtual terminal is quite a great comfort.
Uses of Virtual Terminal:
Virtual Terminal, as I explained above, is used to send or receive data to or from the serial port. Serial port is a 9 pin port which is mostly find on the computer. In most of the projects, the data is sent from the hardware to computer via this serial port and then user design some application on the computer to view that data in some representable form.How to Use Virtual Terminal in Proteus ISIS?
- First of all open the Proteus ISIS and click on the P button to search for the components,
- Now in the search box type “COMPIM” , when you search this a result will show up as shown in the below figure:
- After Selecting this, click OK to add this component in the database.
- COMPIM is the serial port in Proteus and using its properties we can assign any COM pin of our computer to it and it will behave like that pin. We will change the properties shortly.
- Now, click on the Virtual Instrument Mode and then on the Virtual Terminal.
- Now join the TXD pin of COMPIM with the TXD pin of Virtual Terminal and RXD with RXD.
- Now, double click on the COMPIM to open the Properties menu and set the properties.
- I have selected COM1 and my baud rate is 9600, you can set it whatever you want like if you are using the COM3 then set the port to COM3 and baud rate of your own choice.
- Similarly open the properties of the virtual terminal and make sure that the baud rate is same in both the cases.
- Now connect your hardware with the computer and play the simulation. Again make sure that the port which you have selected for the COMPIM is same port with which you have attached your hardware.
- After you play the simulation a black window will open up which will show the data coming from your hardware to the COM1 .
- This black box is actually the Virtual Terminal which is showing data coming from my hardware.
- If you play the simulation and this Virtual Terminal doesn’t pop up then right click on the Virtual Terminal Component and then click on Virtual Terminal which will be at the end in the options and this black window will open up.
