ProMARK X
If no connection is established after two
minutes, the receiver will read NO SIG-
NAL to indicate that it was unable to
establish a connection.
cabling and restart the process.
Once a connection is established, the
receiver will display the message RE-
CEIVING. At this point, the ProMARK X
is accepting the corrections being input.
These corrections are then applied au-
tomatically to fixes being computed by
the receiver.
When the ProMARK X-CM is receiving
broadcast corrections, it will indicate
that the corrections are being applied to
position fixes by displaying a "D" on the
position display when POS is pressed. If
you then go to DIF6 and toggle to OFF
and then return to the POS display, the
"D" is no longer displayed indicating
the broadcast corrections are no longer
being received and applied to the posi-
tion fixes.
FILE STRUCTURE
Since you have now learned how to initiate data collection with the
differential functions, it is now appropriate to summarize the file structures
for files created with these differential functions.
The ProMARK X is capable of creating attribute files both on the PC and on
the receiver. These files will contain a .ATR extension regardless of what
name is given to the file. Normally, the file name will be structured as
1203W002.ATR, with 1203 being the date, W being an arbitrary file type
indicator, 002 being a file sequence number which will increment by 1 each
time a file is created. The file itself will contain a list of attributes and up to
99 key assignments for the attributes.
