Acquiring the
NTRIP Source
Table
After the $PASHS,NTR,PAR command has been sent and the
modem state has switched to INIT, you can ask the receiver
to get the source table from the caster.
NOTE: The modem INIT state is indicated on the receiver
front panel when the following icon (static) appears in the
lower line:
. The number of bars is proportional to the
strength of the signal received by the cellular antenna. You
can also use the $PASHQ,MDM to read this state.
Initialize the modem. Wait a few seconds
until the receiver can respond to this com-
mand.
NOTE: If the initialization fails, the message
$PASHR,MDM,INI,FAILED*7D is returned.
