5 User Interface
M-9129 provides 2-wire digital UAR port for communication of GPS position
data using NMEA protocol or M K extension protocol. UAR port is capable of
4800 to 115200 baud rate.
5 1 NMEA Protocol
M-9129 is default to support standard NMEA-0183 protocol. In addition, a
series of M K extensions (PM K messages) have been developed that can
be used to provide extended capabilities common to many applications.
5 2 NMEA Protocol format
M-9129 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

6 3 Recommendation reflow profile
1. We strongly recommend that this module should be designed to mount on
top side of motherboard with main chip together which process the final
reflow.
2. he maximum frequency of this module to pass reflow process should be
no more than twice, including repair operation, otherwise it may cause side
effect to the performance.
3. Below is the recommend reflow profile referred to Main M K chip set.
