$PSTMPPS,2,15,0,0
Example
:
Enable the T-RAIM algorithm and set the alarm threshold to 20 nanoseconds:
$PSTMPPS,2,15,1,0.00000002
This command is used to set or modify a system parameter in the SL869 module
configuration data and is described in the Authorized User Guide. It can be used to configure
certain parameters related to the Position Hold and TRAIM featured for timing purposes as
shown below.
It is important to note that after parameters have been configured, the $PSTMSAVEPAR
command must be sent to store the updated values in flash.
As explained in the SW Authorized User Guide, message output can be controlled using the
command
$PSTMSETPAR,1201,<mask><mode><cr><lf>
where
mask
is a value representing the bit assignment(s) for the message or messages to be
controlled. The message will be enabled if
mode
is 1, or it will be disabled if
mode
is 2. The
table below lists the bit masks for output messages supported by the SL869-T timing
firmware, which are in addition to those supported by standard firmware.
Message

Mask
PSTMTRAIMSTATUS

PSTMTRAIMUSED

PSTMTRAIMREMOVED

On
0x2000000
PSTMPOSHOLD

Note 1: TRAIM messages are all controlled by the same bit.
Example:
Enable output of the $PSTMPOSHOLD message:
$PSTMSETPAR,1201,4000000,1
The message will be output after the SL869-T is given a software reset command (e.g.
$PSTMHOT) or the setting is saved to flash.
