The required hardware differs depending on whether you are making a local con-
nection or a remote modem connection.
Local Connection Hardware Requirements
The following additional hardware is required for a local connection:
▲
Computer running Windows™ 95, 98, ME, NT 4.0, 2000, or XP with at least 5

files containing data stored at a 30 minute archive interval require approxi-
mately 132K of disk space per month of data. The file size changes in a linear
fashion depending on the archive interval. For example, data stored at a 1–
minute interval requires approximately 3.9 MB per month while the data
stored at a 2–hour interval requires approximately 33 KB per month.
