If the letter or number is displayed in the response message, the option is available. If
the letter/number is not displayed, the option is not available. Table 1.3 lists the
available options.
[B] RTCM Base
The receiver has the ability to be set as an RTCM differential base station and can
output real-time differential corrections when this option is enabled.
The output will be in RTCM-104, Version 2.2 format message types 1,3,6, 16 and 22
as well as RTCM Carrier Differential 18, 19, 20, and 21. For messages 18, 19, 20, and
21, the J option is also required.
[U] RTCM Remote
The real-time differential corrections are available when this option is enabled.
The receiver will decode the RTCM-104, Version 2.2 format message types 1,3,6,9,
16, and 22 as well as types 18, 19, 20 and 21. For messages 18, 19, 20, and 21, the J
option is also required.
[E] Event Marker
The [E] option enables the storage of event times created from a trigger signal. The
receiver measures and records event times with high accuracy (down to one
microsecond). The receiver stores an event time at the rising edge of the trigger signal
(or the falling edge on command) and the time is recorded in the receiver’s PC
memory card and/or output through the TTT NMEA message.
