3.2.1.2 Extended NMEA command description

Please note that all extended NMEA commands beginning with $PSRF111 are for internal

test purposes only. Whereas all extended NMEA commands beginning with

$PSRF112 and

$PSRF109

are implemented for configuration of history, alarm and remote tracking function.

Please note that all NMEA commands, which have to be sent to the XT55 module, are

accepted when the

End Sequence <CR><LF> is also included. The End Sequence

<CR><LF> tells the GPS receiver that the received command is terminated and incoming

next string is new command.

• The CR – Carriage Return (ASCII code 13), which positions the cursor to the left side of

the current line of characters

• The LF - Line Feed (ASCII code 10), which moves the cursor down one line on the input

commands.

All commands listed below are available for direct connected XT55 as well as for remote

configuration (except the

$PSRF111 command).
