$RTCA... (RTCAA)
Use this special data input command to directly input NovAtel 
RTCAA
 differential corrections data, ASCII format.
The data can be accepted using 
COM1
 or 
COM2
.  The differential corrections will be accepted and applied upon
receipt of this special data input command.
The data is generated from a GPSCard 
RTCAA
 log and is accepted by a GPSCard remote station as in the following
format:
$RTCA,990000000447520607BE7C92FA0B82423E9FE507DF5F3FC9FD071AFC7FA0D207D090808C0E

$RTCM... (RTCMA, $RTCM1A, $RTCM3A, $RTCM9A, $RTCM16A, 
RTCM59A)
Use this special data input command to directly input 
RTCMA
 differential correction data, ASCII format (
RTCM
 data
converted to ASCII hexadecimal, with NovAtel header added).  The data can be accepted using 
COM1 
or 
COM2
.
The differential corrections will be accepted and applied upon receipt of this special data input command.  See
Chapter 6, Message Formats, RTCM Commands and Logs, for further information on 
RTCM
 related topics.
The data is generated from a GPSCard 
RTCMA
 log and is accepted by a GPSCard remote station as in the following
format
$RTCM,664142404E7257585C6E7F424E757D7A467C47414F6378635552427F73577261624278777F

NOTE : The $
RTCA
 and $
RTCM
 commands allow the user to intermix differential corrections along with other 
ASCII commands or logs over a single port.  (You must, however, ensure that the 
ACCEPT
 command option is 
set to “
COMMANDS
”.)
TIP : 
The decoding success and status of $
RTCA
 and $
RTCM
 records can be monitored using the 
CDSA
/
B
 data 
log.  These commands will not generate any reply response from the command interpreter.  They will simply be 
processed for valid format and checksum and used internally.  If there is any problem with the data, characters 
missing or checksum fail, the data will be discarded with no warning message.
