NOTE:TIMEMARK1PPS(default)/ RESET (option)
This pin default is provides 1 pulse per second output from the M-87
engine board, which is synchronized to within 1 microsecond of GPS time. The
output is a CMOS 2.8V positive level signal. Only upon a situation of tracking
or navigating will output once per second.
The secondary option function is provides an active-low reset input to the engine
board. It causes the engine board to reset and start searching for satellites. (This
second function setting need contact factory).
