1 For a Base, the user must set the output port. A rover accepts the identified correction
format on any input port.
When a Base Mode is activated, all necessary RTK messages required to support it are
automatically turned on. For example, when BaseRTCM1003 is ON, the 1003, 1011, and
1033 messages are automatically scheduled. It is easy to determine which messages are
scheduled by either saving the current receiver settings to a profile (see the PROFILE
command) or by querying the appropriate port for the current settings using the OUTPUT
command).

2 The SF-3040 does not support MBRTK mode, so the DYNAMIC keyword is not
applicable to the SF-3040 when configured as a base.
Table 83: Base Modes
Mode Description
Rover Receiver operates as a rover; all ports accept corrections
BaseRTCM1 Receiver operates as an RTCM type 1 and type 31 base station
BaseRTCM9 Receiver operates as an RTCM type 9 and type 34 base station
BaseRTCM1819 Receiver operates as an RTCM type 18/19 base station.
BaseRTCM2021 Receiver operates as an RTCM type 20/21 base station
BaseCMR Receiver operates as a CMR base station
BaseCMRPLUS Receiver operates as a CMR+ base station
Base5B
1
Receiver operates as a proprietary 5B (10 km) base station; supports legacy
products
Base5E
2
Receiver operates as a proprietary new 5E (40 km) base station
(to support multi-GNSS RTK)
BaseRTCM1001 Receiver operates as an RTCM 3.0 type 1001 base station
BaseRTCM1002 Receiver operates as an RTCM 3.0 type 1002 base station
BaseRTCM1003 Receiver operates as an RTCM 3.0 type 1003 base station
BaseRTCM1004 Receiver operates as an RTCM 3.0 type 1004 base station

1 The Base5B message must be used when the NCT-2100D product family (NCT-
2030, RT-3010, RT-3020, SF-2040, or SF-2050) will be receiving the RTK
corrections. Base5B schedules the x5B and the legacy version of x5E message to
support this older generation of products.

2 Base5E supports all GNSS RTK corrections, including GLONASS and WAAS. In
the future, it will support Galileo and COMPASS.
