Thank you Morgan. I forgot to document TTL-RS-232 device.
Here is a picture of concoction. (total price around $14 USD which was cheaper than the Sure GPS)
I had a magnetic tiny GPS antenna sitting around with a 12 foot cable. The media panel is near a basement windows with a SW exposure so will be mounting GPS on media board and using external GPS magnetic antenna.

Purchased one of these from Amazon.
Uxcell a14041500ux1216 MAX232CSE for $7.37
Wired PPS from GPS to Pin #1 on the above mentionsed TTL to RS-232.
[sharedmedia=gallery:images:1195]
Then noticed that the 4 comm ports were disabled via the BIOS. Enabled one com port (first one).
Then saw traffic via cat cuau0 serial port.
and checked via ntpq
ntpq> cv
associd=0 status=0012 1 event, clk_bad_format,
device="NMEA GPS Clock",
timecode="$GNGLL,xxxxx", poll=89,
noreply=0, badformat=1, baddata=0, fudgetime2=400.000, stratum=0,
refid=GPS, flags=7
and checked status of NTP server via PFSense and see that it is working fine now.
[sharedmedia=gallery:images:1196]
So I am now done with the GPS / PPS part of this little project.
Next the UPS and connectivity to PFSense UPS monitoring.
Wanting to mount the UPS on a cement wall shelf...so looking for a metal shelf now.
