These files can be edited by any editor as text file. For better
recognition of the relevant lines, each line begins with a counter with
the format C<column>.<sts-nr>.
Please note the following when you edit frame files:
• It is recommended only to edit patterns that have not been
scrambled. Otherwise, the changed bytes have to be scrambled
manually.
• “#” comments out a line (you can add any number of comment
lines).
• Do not edit parity bytes. When frame files are converted, a ll parity
bytes are recalculated. Any changes you made to parity bytes are
lost.
• The synchronizing pattern in row 3, column 1 to 6 may be edited.
However, there may be p roblems if this p attern is not u nique within
the frame.
