Hello
I'm having a bit of a problem with a W1 Wattmeter, and need some advice !
The W1 communicates with the computer under Windows XP just fine with
a USB to Serial adapter. I can read data from the watt meter and store
user parameters just fine.
Under Windows 7, I can read data from the W1 with either of two USB to
serial
adapters and also from hardware serial ports on the computer. I can not
write
user parameters to the W1 with any combination of serial devices.
I have tried every trick I know, with no luck. The firmware version on
the W1 is 1.05
It looks like the Windows 7 machine is sending data to the W1 too fast,
but that
is speculation on my part. Anyone else see this ??
