System Name
Enter a descriptive name for the unit. This name can help you
distinguish between different installations. Enter up to 20 alpha-
numeric characters in this field, including spaces and special
characters (such as an underbar). The name is then displayed in the
terminal menu. This selection is only available for the terminal
interface.
System Time/Date
Set the current hour, minute, day, month, and year. This is used to
date/time stamp all statistical data captured by the DSU IQ.
History Interval Size (HST INT SIZE)
The time entered in this field affects the I
NTERVAL
V
IEW

menus. The I

IEW
provides historical data for
the current day. The data is divided into columns grouped by the
interval of time (
5 , 10 , 15 , 20 , 25 , or 30 minutes) selected in this
field. The DSU IQ stores up to 157 intervals. Once the maximum is
reached, new information overwrites existing information,
beginning with the least current.
If data is not retrieved before the Total Time Stored is exceeded, it is over-
written and cannot be restored. Total Time Stored = History Interval Size
x History Interval Count.
