Appendix A. Using Serial Commands

Introduction to Serial Commands

Serial commands allow you to communicate directly with the

receiver in its proprietary command language. Serial

commands can be used for various purposes such as:

• Changing default settings

• Monitoring different receiver statuses (internal operation,

constellations, etc.)

• Outputting messages on request

• Installing firmware options, etc.

Serial commands fall into two categories:

• Set commands ($PASHS,...), used to set or modify the

receiver’s internal parameters.

• Query commands ($PASHQ,...), used to interrogate the

receiver.

Standard NMEA messages will all be output with the

standard ASCII NMEA preamble (e.g. $GPGGA) and not with

the “$PASHR..” preamble.

The few conventions used to describe the serial commands in

this manual are summarized in the table below.
