LTZ: Local Time Zone
$PASHS,LTZ,d1,d2
This command allows you to enter an offset value from Greenwich Mean Time
(GMT) in order to derive local time, where d1 is the number of hours and d2 is the
number of minutes that should be added to or subtracted from GMT to get local
time. The range for d1 is -13 to +13; the range for d2 is 0 to 59. Issue the command
$PASHQ,ZDA to get current local time offset values, which are displayed in the last
two fields before the checksum. See the section in this chapter entitled “NMEA
Commands/Responses” for more information on the ZDA message.
Examples
Enter the following command to add an offset of +7 hours to GMT:
$PASHS,LTZ,+7,0
Enter the following command to add an offset of -4 hours, 25 minutes:
$PASHS,LTZ,-4,25
MEM: Results of Last Memory Test
$PASHQ,MEM,[c1]
This command allows you to query for the results of the last memory self-test
performed by the G12, where c1 is the optional port designator for the output of the
response. If a port is not specified, the receiver sends the response to the current
port. The G12 performs a memory test each time it is powered up.
This message outputs without a header or message identifier. The response
message is output in the format:
h1,h2,h3,h4,h5
DEFAULT SETTING
LPS—10, 3, 1
DEFAULT SETTING
