Hello,

I have two USB Type A to UARR FT232 hardware which I connect on the same pc so that i can transfer data from one software to another using the COM ports generated by this. I tried communicating with hterm, and they work perfectly even on different baudrates. But then when I tried to do this with two labview based softwares and it is not working. The baudrates for the softwares are all set correctly, but it is not working. I used to use these softwares with virtual com ports. And it was working. But the problem is my company changed my laptop to a newer version with new admin rules. So for the virtual com port to work, i need to make such changes in my old laptop, but it is not allowed in my old laptop because of admin rules. So i had to buy this hardware for doing this. The hardware is working fine, as i said it worked with hterm and those software also work fine with virtual comports. But the hardware is not working with these two softwares. And I dont know how to debugg this issue. Can you give me ideas on what I can do to solve this issue. Thank you.

 

Just a thought. Did you crossover RXD and TXD?

yeah, i connected to rxd to txd and txd to rxd, thats why it worked with hterm.

 

image shows that they are wired correctly (orange and yellow wires crossed). and you already confirmed that it works.

if this was the issue is with rights or policies on your machine, you probably would not see the com ports in the device manager.
it may be due to actual port settings - since you are only using RX/TX, there is no hardware handshaking. any terminal software does allow selecting such option. but.. does the software you are trying to use (labview) allow it?

 

Why do you need the hardware interface if both apps are running on the same system? I'm not a Windows guy, but I think the connection can be simulated:

Google "windows simulate rs232 bridge"

That's what I get for skipping ahead to save time.
