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).

5. User Interface
M-87 provides 2-wire digital UART port for communication of GPS position data
using NMEA protocol or MTK extension protocol. UART port is capable of 4800 to
115200 baud rate.
5.1 Protocol
M-87 is default to support standard NMEA-0183 protocol. In addition, a series of
MTK extensions (PMTK messages) have been developed that can be used to provide
extended capabilities common to many applications.
5.2 NMEA Protocol
M-87 is capable of supporting following NMEA formats:
NMEA RECORD Description
GGA GPS fix data
GLL Geographic
GSA GNSS DOP and active satellite
GSV GNSS Satellites in view
RMC Recommended minimum specific GNSS data
VTG Course Over Ground and Ground Speed
ZDA Time&Data
