SW4048 REV? [RE-wrenches]

[Roy Dyngen]

Dave,

The way to tell if you have the newer version 4.2 software in your 
inverter is to check the rev under menu heading 3.  The older 
problematic version will read only "Revision 4.2" on the display.  The 
newer fixed version will also read "SW Series" in the same window.  As 
for the TM500's, please contact me here at Xantrex and I will make it 
good.
