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 GPS-DEBUG: $GPRMC,181436.0,A,3009.798,N,09550.252,W,000.00,000.0,251113,05.5,E*76 GPS-DEBUG: mon: 10, gps_time: 1385403276, ctime: Mon Nov 25 18:14:36 2013 GPS-DEBUG: $GPRMC,181437.0,A,3009.798,N,09550.252,W,000.00,000.0,251113,05.5,E*77 GPS-DEBUG: mon: 10, gps_time: 1385403277, ctime: Mon Nov 25 18:14:37 2013 GPS-DEBUG: $GPRMC,181438.0,A,3009.798,N,09550.251,W,000.00,000.0,251113,05.5,E*7B GPS-DEBUG: mon: 10, gps_time: 1385403278, ctime: Mon Nov 25 18:14:38 2013 GPS-DEBUG: $GPRMC,181439.0,A,3009.798,N,09550.251,W,000.00,000.0,251113,05.5,E*7A GPS-DEBUG: mon: 10, gps_time: 1385403279, ctime: Mon Nov 25 18:14:39 2013 GPS-DEBUG: $GPRMC,181440.0,A,3009.798,N,09550.251,W,000.00,000.0,251113,05.5,E*74 GPS-DEBUG: mon: 10, gps_time: 1385403280, ctime: Mon Nov 25 18:14:40 2013 GPS-DEBUG: $GPRMC,181441.0,A,3009.798,N,09550.251,W,000.00,000.0,251113,05.5,E*75 GPS-DEBUG: mon: 10, gps_time: 1385403281, ctime: Mon Nov 25 18:14:41 2013 GPS-DEBUG: $GPRMC,181442.0,A,3009.798,N,09550.251,W,000.00,000.0,251113,05.5,E*76 GPS-DEBUG: mon: 10, gps_time: 1385403282, ctime: Mon Nov 25 18:14:42 2013 GPS-DEBUG: $GPRMC,181443.0,A,3009.798,N,09550.250,W,000.00,000.0,251113,05.5,E*76 GPS-DEBUG: mon: 10, gps_time: 1385403283, ctime: Mon Nov 25 18:14:43 2013 GPS-DEBUG: $GPRMC,181444.0,A,3009.798,N,09550.250,W,000.00,000.0,251113,05.5,E*71 GPS-DEBUG: mon: 10, gps_time: 1385403284, ctime: Mon Nov 25 18:14:44 2013 GPS-DEBUG: $GPRMC,181445.0,A,3009.798,N,09550.250,W,000.00,000.0,251113,05.5,E*70 GPS-DEBUG: mon: 10, gps_time: 1385403285, ctime: Mon Nov 25 18:14:45 2013 GPS-DEBUG: $GPRMC,181446.0,A,3009.798,N,09550.250,W,000.00,000.0,251113,05.5,E*73 GPS-DEBUG: mon: 10, gps_time: 1385403286, ctime: Mon Nov 25 18:14:46 2013 GPS-DEBUG: $GPRMC,181447.0,A,3009.798,N,09550.250,W,000.00,000.0,251113,05.5,E*72 Enter Selection (1-27,97-99,r,q,d) : S/W Version: 1.38 10/09/2013 System Uptime: 1747.0 Secs IP Address: 192.168.33.80 Netmask: 255.255.255.0 Gateway: 192.168.33.1 Primary DNS: 192.168.33.1 Secondary DNS: 8.8.8.8 DHCP: 0 VOTER Server IP: 192.168.33.60 VOTER Server UDP Port: 667 OUR UDP Port: 667 GPS Lock: 0 Connected: 0 COR: 0 EXT CTCSS IN: 1 PTT: 0 RSSI: 0 Current Samples / Sec.: 0 Current Peak Audio Level: 53448 Squelch Noise Gain Value: 18, Diode Cal.
