[time-nuts] need programmable pulse output

[Ed Palmer]

Hi Pieter,

Is this what you're looking for?

    1PPS TIME OFFSET COMMAND (@@Ay)

    The GPS receiver outputs a one pulse-per second (1PPS) signal with 
the rising edge
    placed on top of the GPS/UTC one second tic mark. The 1PPS Offset 
command allows
    the user to offset the 1PPS time mark in one nanosecond increments. 
This offset can
    be used to place the 1PPS signal anywhere within the one second epoch.

This command is available in the Motorola M12T, M12+, UT+, and VP boards. 

For more modern boards, the same command is implemented in the I-Lotus 
M12M and the Navsync CW-25 module with the Motorola firmware load.  Be 
careful if the programmable 10 MHz output on the CW-25 is of interest to 
you.  I bought it last year and at that time it was NOT programmable 
with the Motorola firmware load.  It's fixed at 10 MHz unless you get 
Navsync to do some custom development.  The speed is only programmable 
with the NMEA firmware load.
