I'm at my wits end, and I'm hoping some of you guys might be able to help. I'm finally getting around to updating my two TIUs to 4.2 with Loader 2.3, and I'm hitting a brick wall that I just can't get around. I haven't updated the TIUs in some time, so I'm a bit rusty, but I can't figure out what I'm missing here.
I am using a laptop running Windows 7 (32 bit, professional) and a USB to serial converter (same hardware I've used before, except it's a new installation of Windows; not an update from XP). The old version of the loader was NOT on the machine prior to installing 2.3. I installed Loader 2.3 (downloaded the 32 bit version), and downloaded the software for the TIU. Here's a step by step of what I'm seeing here:
1). Connect USB to serial adapter to the machine. Windows recognizes it for what it is, and assigns it COM5.
2). Connect serial adapter to the TIU (TIU is off).
3). Connect a stereo (I'm 99.9% sure it's stereo) connector between the ProtoCast and ProtoDispatch ports on the TIU.
4). Apply power to the TIU. Red light in TIU is solid.
5). Open the Loader program.
6). Select Options > Serial Port > Auto Search for TIU
7). Press start button.
8). Status window says, "Searching for TIU on COM5," and a pop-up windows says, "WARNING: Unable to search for TIU on COM4". Press OK.
9). Another window pops up, saying, "WARNING: Unable to search for TIU on COM 3". Press OK.
10). Another window pops up, saying " Auto Search for TIU is complete! TIU found on COM5." Press OK.
11). Select System > Send Code to the TIU. Press Start.
12). Navigate to the TIU 4.2 update file and select it.
13). Status window shows that the update file is loaded and says, "Searching for TIU on COM5...."
14). Eventually the loader times out and gives an error window that says, "WARNING: The program is having a hard time finding a TIU connected. Confirm that all the [sic] connections are correct and cycle the power on the TIU."
Cycling has no effect, and I've confirmed all of the connections. This is happening to two separate TIUs so I don't think it's the MTH hardware.
So to boil it down, does anyone recognize these symptoms? Is it an audio cable problem? Serial? Windows 7? .NET?
Any thoughts are greatly appreciated.
Thanks,
