- For timecode generators:

timecode format, timecode mode, time to seed, user bits to seed

If you don’t specify parameters, the default values are used. You can
override the defaults in the .cfg file, or by using the API calls. Acceptable
values for these parameters are shown in Table 14

Each resource allocation line is assigned an index number in sequential order
independent of comment lines or crosspoint lines. Thus, the first resource line
found in an NCS file is assigned index number 1, the second is assigned index
number 2, etc. These index numbers may be used by the crosspoint lines, which
are described in the following section.
