How about this: Dig in the KW11-P manual if its available and see if there
is any info on replacing a KW11-L with it. Maybe that will tell you where
that LTC L signal is.
Have you tried this with M7800 and M787 instead
of M7228?
I'd say if
not, try that, if yes, and if that works, then
look over the DL11-W
manual for some sort of compatibility issue with the 11/45.
This is
just speculation, but it's possible that you
may have to use a M787
and disable the RTC on the DL11-W or something strange like that.
I don't have a M787 card. This system arrived with two
M7800's and a M7228.
No KW11-L. It came with the M7228 (KW11-P). From what I can
tell, the M7228 can provide several different time clocks,
one of which is LTC based as an option if you run an
additional wire, but not at the normal address for the LTC.
I want to see first if the power supply is generating a LTC L
signal, and then see where it goes. Right now I'm trying to
just find the signal. It would obviously go to slot 1C
somewhere for the M787. But I can't seem to figure out if it
was by default also provided to a pin in the 3 unibus slots
built in to the system unit in order for the DL11-W to take
advantage of.
