Username Username for authentication string (128 character max; must be
captured within quotation marks “”)
Password Password for authentication string (128 character max; must be
captured within
quotation marks “”)
NMEA GGA Whether transmission of NMEA GGA is
required Keywords: OFF, ON
Autoconnect Whether or not NTRIP should try to connect
automatically to a caster at power-on or at idle Keywords: OFF, CLIENT, SERVER
Correction port The local port to use for NTRIP connection
(SF-3050 only)
Keywords: ETH, MOBILE
Authentication The authentication method to use for NTRIP
connection (SF-3050 only). Keywords: AUTO, BASIC, DIGEST
Examples:
[NTRIPCONFIG] “69.44.86.66”, 2101, “LASC_RTCM3”,,,ON, MOBILE
Configures the caster at IP address 69.44.86.66, on port 2101, and obtains
corrections from the server connected to mount point LASC_RTCM3. Uses the
mobile cellular modem to connect to the Internet and sends an NMEA GGA
sentence as part of the handshake.
[NTRIPCONFIG]
[NTRIPCONFIG] "69.44.86.68", 2101, "LASC_RTCM3", "", "", OFF, ETH
Displays current settings

Some NTRIP casters, such as SmartNet Aus, have a nonstandard interface to the
NTRIP server/source/base station. In this situation, the caster makes a TCP/IP
connection to the NTRIP server, rather than the server connecting to the caster. To
accommodate this feature, if the special caster name, RTK NETWORK, is used in
the NTRIPCONFIG command, the server will listen to and accept TCP/IP
connections on the port specified as the caster port in the NTRIPCONFIG
command, using the IP address specified using the ETHCONFIG command.

Some NTRIP casters, such as Iowa DOT return 401 without any other header
information such as “WWW-Authenticate: ”. In this case, the unit will
not only be able to determine which authentication method to use, but it will not be
able to do Digest authentication at all since the caster is not following the NTRIP
standards. In this case, the user should use BASIC arg and attempt to connect with
Basic authentication.

The NTRIPCONFIG will initially get the Source Table of any caster, if the format
argument (4
th arg) is NCT, then the client will know that it is talking with a StarFire
Caster. If that is the case, then it will use DIGEST authentication to connect to the
Starfire Mountpoint.
