Hi Galen and others,
Thanks to this thread  :) I found out what caused loss of Ethernet connection after replacing the battery in my TDS3014B. When I bought the 'scope a few days ago, both RTC and Ethernet connection were flaky. The RTC is fine now.

You said (above) that you used your TL866II to copy the contents of the 3014B file (from elsewhere) into your DS1742W. I have the file but AFAIK, the TL866II does not support the DS1742W directly. Do you remember what target device you specified? Does the DS1742 allow Vcc of 5 V or above? The datasheet suggests it does but I'd rather not kill my DS1742W.

Pls select DS1220

DS1220 is 5V not 3.3V.
DS1742W is 3.3V
TL866II already has DS1742 in its list but it is also 5V.

For what it's worth, I read/wrote a DS1742W with a TL866 before it occurred to me it was giving it 5V. It did no (apparent) damage but had I realized at the time I would not have done this. Later I wired up an adapter to one of my FPGA boards and used the switches and displays on that to manually write a few bytes.
