RTCM commands allow you control and monitor operation in differential mode.
RTCM commands are available if the differential options are installed. If only the
base station option [B] is installed, only commands controlling base station
parameters are available when setting the receiver for differential operation. If only
the remote differential option [U] is installed, only commands controlling remote
station parameters are available when setting the receiver for differential operation.
Both options must be installed in order for base station commands and remote
station commands to be available to the receiver. The RTCM mode is off by default.
All but one of the RTCM commands are set commands. The set commands allow
you to enable and modify a variety of parameters affecting differential operation.
There is only one query command:
$PASHQ,RTC . This command is used to
monitor differential parameters and status. Table 9.1 lists the RTCM commands.
