PROBLEMS:
My VX2 resets, goes back to VFO, or i get an ERROR immediately when I try to write!

SOLUTION:
The config info in the VX2 does not match what is in the file being sent.

Goto Advanced > Mods
Under "VX-2 Hardware Settings", for "When Writing Use:", be sure "Radio Data" is selected.
Read from the VX2. It does not matter what is in the VX2.
Open the file you want to write, and write it to the VX2.





PROBLEM:
I can read from the VX2 just fine, but I cannot write data that I read back to the VX2!
Or
The write seems to go OK at first (RX for a while), but you eventually get an ERROR.

SOLUTION:
On some PCs, the software routine that writes to the VX2 is executing too fast, and 
the VX2 cannot receive the data quick enough. I think this happens mostly on XP. 

To slow it down:

Go To Settings > Port.
Click the "!" button. This will display the "Write Delay" dialog.
The default value is 9. I believe that this should work for 99% of PCs.

Try higher values to make the write take a little longer (12, 15, 18, etc).
Increase the value a little, and try to write to the VX2 again. 
However, note that very high values may cause corruption or a clone error.

NOTE: This value will NOT fix problems reading from the radio or anything else.




PROBLEM:
I cannot read from the VX2, I push the [BAND] key and the software doesn't respond!

SOLUTION:
If you do not see any response data, then there is a 99% chance you have one of the following problems:

Your cable has a bad connection. Be sure it is FIRMLY plugged into the PC.

Your adapter has a bad connection. Be sure it is FIRMLY connected.

It is possible you may have a bad cable or adapter. If you purchased your cable 
from RT Systems, read the help on their website and use hyperterminal to test your cable.

Your port setting in VX2 Commander is not the one the cable is connected to.
This can be set under Settings > Port. 





PROBLEM:
I have tried to read from the VX-2 many times, but I always get an "Invalid
Checksum"!

SOLUTION:
Double check to be sure all of your connections are good.

Try a "Set Mode Reset".

Try a Microprocessor Reset.

Try it on another computer. 

If it does work on the other computer, you may have an issue with your COM port hardware on 
the problem computer.
If it does not work on the other computer, then something is bad between the VX2 and the PC 
(Cable, adapter, etc)

For best results, I recommend the six-transistor design found on this site:
http://home.comcast.net/sllewd/vx7rmain.htm
or purchase a commercially made cable.




PROBLEM:
I encounter errors trying to use VX-2 Commander with my USB to serial adapter!

SOLUTION:
Try going into device manager, COM port settings, advanced. Slide both FIFO Buffer sliders all the way to the left.

Try another USB to Serial adapter. The following model has been reported to work with one of my other programs, VX7 Commander:

Manufacturer: Belkin
Model#: F5U109
Cost: 29.99
Where: Circuit City (in the PDA section)
Settings: default Com setting, except for FIFO buffers turned all down)
