I know that there have been some other emails about this that I have not had time to
read, since I worked 13.5 hours yesterday and 13 hours the day before. I will probably
be doing it again tomorrow, so if you have time today (hopefully), I will be happy to
contact you directly (like on the phone or something), and work with you to resolve this
problem.
From what little I can see here, I have a serious problem believing that a 10us pulse
is too short. I think it is likely to be something else.
Please email me off-list with contact info.
Thanks

Subject: [App_rpt-users] Trimble SVeeEight GPS to RTCM
We are trying to interface a Trimble-SVeeEight-Plus to the RTCM. I am running the S/W Version: 1.38 10/09/2013 on the RTCM and I am seeing the GPS info listed below in Debug mode 32 but I think I may be having issues with the PPS. The Trimble indicates that it has a 10 microseconds negative going pulse I noticed that the Garmin GPS 78X LVC has a default pulse width of 100 milliseconds. I am wondering if the Trimble is too fast for the RTCM.. is this going to be a problem?? It appears that I cannot adjust the pulse width on the SVeeEight as its grayed out.. any ideas. Your help would be greatly appreciated. Thanks Gary Kc5daq..
The 1PPS signal is an open collector interface on pin 9 of Ports 1 and 2. The polarity of the
PPS signal is an inverted, 10 microseconds negative going pulse with the falling edge synchronized to
UTC
