Satellite # _____

Speciﬁ es the number of the satellite you are currently editing. If
you would like to edit a different satellite, move the cursor to this
ﬁ eld using arrow keys, enter the desired satellite number, and press

Analog Output #_____

This ﬁ eld actually contains two separate ﬁ elds. The ﬁ rst ﬁ eld
speciﬁ es the point “type” (i.e., analog input, control output, analog
output, etc.) and displays the current type in textual form. Because
this is a “choice” ﬁ eld, the list of available choices will be displayed
at the bottom of the screen:

CHOICES:

Make your selection by pressing the

once for each

choice until the desired point type has been selected. (If you select
a point type that is different than that currently being displayed, the
screen will be rewritten with the appropriate screen and data.

This second ﬁ eld speciﬁ es the point number to edit. For the
Analog Output Screen, this number can range from one to eight,
corresponding from P1 to P8, respectively. If you would like to
edit a different point, simply position the cursor to this ﬁ eld by
using the cursor positioning (arrow) keys, enter the desired point
number, and press

Description

This is displayed on Summary and Data Entry/Editing Screens to
aid you in remembering points within the system. You may enter
up to ten characters (control codes, ALT codes, and the double
quote character are not allowed).

Filter

Time Constant:

_____ seconds

Speciﬁ es the reaction rate of the analog output. This is generally
used to slow down the rate at which the analog output changes
voltage to reduce “hunting.”

Because this is a “choice” ﬁ eld, the list of available choices will be
displayed at the bottom of the screen:

CHOICES: <0, 1, 2, 4, 8, 16, 32, 64>
