TABLE DATA ADDENDUM

AD-1

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

ame in either case.
