Which route did you take-- PPS pin to RS232 (CMOS level) or via the
buffers/inverters?
All I am pointing out to people who might regard the sure board as a
really cheap path, but do
I've done some more careful inspection of the Sure GPS comms trace:
It really looks like the GPS does _not_ listen to commands by default,
instead the controlling program sends a solitary '0' char to ask for
permission to talk.
About 200 ms later the GPS boards drop the CD (Carrier Detect)

Hello all:
I'm trying to set up a linux ntp server using IRIG as a time source,
from a SEL 2407 (http://www.selinc.com/sel-2407/). Unfortunately,
I've not managed to get this running yet.
I'm running IRIG as this clock does not put out NEMA. I am presently
working with PPS from this clock,

Have you tried flag3 to enable
Chris Co.,
The usual problem is overdriving the computer input.. Most IRIG devices
produce a modulated signal in the range 10 V P-P, which is far larger
than the line-in level. You might need an attenuator to produce in the
order of 1 V P-P. As Chris says, the best way is to monitor the line
