I believe the internal GPS engine is called the US Globalsat EM-406 if you buy it without the round plastic case and cable. The EM-406 is documented to have PPS on test point 10 and perhaps pin-6 of its 6-pin I/O header. (Other versions of the http://www.usglobalsat.com/downloads/engineboards/EM406.pdf The bad news is that this pin doesn't seem to be brought out on the normal cable for the br-355. http://www.usglobalsat.com/item.asp?itemid=61 (gps) http://www.usglobalsat.com/item.asp?itemid=4 (cable ps-2 -> db9) So it doesn't look like you can get PPS out of the unit without making a new cable and possibly some soldering. -wolfgang -- Wolfgang S.
