The problem does not change if running under 7 76-bit, while running 6.1 or 2011, SP2 with VISA 5.2(when tested with the Staples 18762 adapeter). If anyone else has ran into this and bought a different USB RS-232 adapter, please add it to the list. Not that its of any help, I have attached a simple test program that shows the problem. I am not sure why my friends USB adapter or the Dyne X work. I then tried the following USB RS-232 adapters: I then used my USB to RS-232 adapter with nothing more than a loopback cable.
We tried some test with this board and it worked.

Note that these PCs both have true serial ports on the bus.Ī friend brought in a small evalulation board that had an USB to serial TTL converter. I ran several tests with two different desktop PCs and they all worked. I attempted the running the software on a different laptop prior to installing 2011. Reloading an image of the hard drive prior to installing 2011 caused the program to start working. Uninstalling 2011 did not cause the program to start working. Running the program as a VI had no effect. Setting the timeout to a very small number does not allow for the same bandwidth as just running a virgin copy of LV 6. The VISA call does throw a timeout error, but adjusting the timeout effects the delay. The data is sent fast, the logger responds fast, then the system hangs for about a second. The basic symptom is the serial communication comes to a crawl.
The $180 in gas and entry fees is nothing compared to the frustration (which is why I still run version 6). I spent a few hours trying to get things working had to throw in the towel. The last time I visted the race track, I go to plug the laptop into the logger and the serial interface no longer works. This software has not changed in a few years and is very solid. I use the laptop to collect data when I go to the race track using a Labview program I wrote that interfaces with the logger using RS-232. I wrote some new software under 2011 and installed it on my laptop. Beside the two bugs I already posted about, I didn't find any other major problems so I upgraded my home PC.

Things were working fairly smooth after my recent upgrade from 2009 SP1 to 2011 SP1.
