TD and PakBus Operating System Addendum for
CR510, CR10X, and CR23X Manuals
AD1 Major Differences
Table Data (TD) operating systems have two major differences from the
standard operating systems: First - the namesake - in the way data are
stored internally and second, in the options available for transferring
that data to external devices. The standard operating systems support
both on site external storage (i.e., storage modules) that may be
manually retrieved and telecommunications. The TD operating systems
have more advanced telecommunication and networking capabilities but
do not support storage modules. There are two versions of the TD
operating system: TD and PakBus. The PakBus operating system
includes the PakBus communications protocol that allows some
additional communications options (Section 12); other features are the
same as the TD operating system.
The datalogger hardware and direct measurement capabilities are the
same in either case.

Internal Data Storage Multiple Data Tables, at least
one Table for each output
