datalogger support software. It provides a view of the CR1000 file
system and a menu of file management commands:

Delete facilitates deletion of a specified file

Send facilitates transfer of a file (typically a CRBasic program file) from

PC memory to CR1000 memory.

Retrieve facilitates collection of files viewed in File Control. If

collecting a data file from a CF card with Retrieve, first stop the
CR1000 program or data corruption may result.

Format formats the selected CR1000 memory device. All files,

including data, on the device will be erased.

LNCMD software

The portion of CR1000 SRAM Memory allocated for storing data tables 
with output arrays. Final Storage is a ring memory, with new data
