Spectracom Netclock/2:
WWVB Synchronized Clock. This clock has proven a reliable source of time,
except in some cases of high ambient conductive RF interference.
The claimed accuracy of the clock is 100 usec relative to the broadcast signal;
however, in most cases the actual accuracy is limited by the precision of
the timecode and the latencies of the serial interface and operating system.
Dip switches:
The DIP switches on this clock should be set to:
24-hour display
AUTO DST off,
time zone 0 (UTC)
data format 0 or 2
and baud rate 9600.
Timecode format:
There are two timecode formats used by these clocks: format 0, which is available
with both the Netclock/2 and 8170; and format 2, which is available only with
the Netclock/2 and specially modified 8170.
This is the configuration that works for me. Endless hours of testing and
troubleshooting to make this clock work. Even though this manual is for Spectracom 8182
I found it very useful, you can downloaded from here. spectracom8182.pdf
The interests are endless, lately I was forced to work with the UNIX
platform in order to interface the netclock/2. I spend an entire weekend looking for a solution to do this in a windows platform. Why did I even
bother, I should have listen to Xaos from the start.
