7.6.3.3.2 Default.cr8 File
Default.cr8 can be stored on the CR800 CPU: drive. At power up, the CR800
loads default.cr8 if no other program takes priority (see Program Run Priorities
(p.
106)
). Default.cr8 can be edited to preserve critical datalogger settings such as
communication settings, but cannot be more than a few lines of code.
Downloading operating systems over telecommunications requires much of the
available CR800 memory. If the intent is to load operating systems via
telecommunications and have a default.cr8 file in the CR800, the default.cr8
program should not use significant memory, such as occurs by allocating a large
USR: drive, or by using a DataTable() instruction with auto allocation of
memory.
