Fellow time-nuts (and Rick in particular),
I have been looking through the E1938A documentation available from
fellow time-nuts. There is some juicy pieces of information, but also
some holes.
I does not recall having seing a datasheet or users manual, as available
for the 10811 devices.
I (think) understand what RX and TX is for, the serial port at CMOS/TTL
levels, as it hookes directly to the PIC. But I wonder what the Data to
PIC, Data from PIC and PIC data ready is meant to do, looks like a
second serial port of some sort.
Also, I found another article on it which is not on Ricks homepage where
various design decisions etc on production is described. I have not
bothered to download it from IEEE, but if Rick could make it available
that would be a welcome and interesting reading.
Cheers,
Magnus
