Hello,
I am developing a test rig and I would like to know which COM Port was assigned to a certain hardware device.
Background:
Until now I have used a ".init" file to assign manually the COM Port to a desired device. This works until someone unplug the tester and plug it in a different PC. Then I need to update the ".init" file and only then the tester can be used. I want to avoid this process and improve my tester.
Hardware used:
I need a TTL-USB converter, for this purpose I am using a FTDI device, specifically the TTL-232RG. This converter works with the integrated circuit FT232R.
Software used:
I work with a Windows 7 OS. The FTDI drivers installed are the version 2.8.30.0 .Labview version is 2013
What I have done:
Until know I can read the COM Ports and the Serial number of the devices but nothing else (See attachment).
I also have tried the DLL approach but FTDI only provides some examples for Labview7 (See attachment), and I still cannot read the COM Port from the DLL ( and I serouosly doubt that this is possible).
I would be very grateful if someone could tell me how can I relate the Serial number with the COM Ports?. I am starting to feel that I need to develop my own USB-hub to solve my problem because it seems that part of the problem is the software plattform used (in this case Microsoft Windows) and probably I need to go down at the physical layer of the communication to achieve my goal.
P.S. I already have read the following documents:
