If you send "ptim:tcod:cont 0", that turns off the automatic (continuous)
It doesn't turn on sending "scpi > " to tell you when it is ready for
Without the scpi, I thought a short delay might be needed. Except for two
cases, it isn't. There may be more cases that I haven't discovered.
The first case is switching to T2 mode. It takes about a second for the scpi
on the Diagnostic port. I assume it's writing to flash. A delay in that
path works without any delay in the normal case.
The other case that needs special handling is the status page. I check for
"Self Test:", then in the normal case discard the scpi.
I have python code that does what I want and works on both J6 (no scpi) and
J8 (with scpi). Every 30 seconds, it reads several parameters and writes
them to a log file, then displays the status page. Poke me off-list if you
want a copy. It's running on Linux but might be easy to port to Windows.
The bottom line is that you (or NTP) can get both the text interface and PPS
on a single connector.
These are my opinions. I hate spam.
