User Interface GR-91 provides 2-wire digital UART port for communication of GPS position data using NMEA protocol or extension protocol. 5. 1 NMEA Protocol GR-91 is default to support standard NMEA-0183 protocol. In addition, a series of SiRF extensions have been developed that can be used to provide extended capabilities common to many applications. NMEA Protocol format GR-91 is capable of supporting following NMEA formats: NMEA RECORD GGA GLL GSA GSV RMC VTG ZDA Description GPS fix data Geographic GNSS DOP and active satellite GNSS Satellites in view Recommended minimum specific GNSS data Course Over Ground and Ground Speed Time & Data 12 HOLUX Technology, Inc.

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. The 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. Below is the recommend reflow profile referred to Main SiRF chipSet. 23 HOLUX Technology, Inc. [. . . ]
