Buffer #:
There are 10 auto-scan/print routines available and are referred to
as buffer #1-10 on this screen.
Description:
You may enter a message as an aid to help you remember what
keystrokes have been programmed in each of the buffers.
Activated:
The auto-scan/print routine will be “activated” or automatically
started according to what is entered here. The 4 choices available
for this input are:
Make your selection by pressing the once for each
choice until the desired choice appears on the screen, and then
press
.
None
If “None” is chosen, the system will not automatically replay the
routine.

Interval: 8 Hours
If “Interval” is chosen to activate the auto-scan/print routine, two
more fi elds appear on the screen to allow you to tell the system
the time interval between the automatic replay of the auto-scan/
print routine. The fi rst input has a maximum range of 0 to 127. The
second input is either Minutes or Hours.
In the Special Keys example table, 8 hours is entered. This means
that the system will repeat the keystrokes that you “taught” it every
8 hours.
At Time: 0800
The auto-scan/print routine can be activated at a certain time each
day by selecting the “At Time” choice. The time is entered in 24-
hour format; that is to say 1:00 pm is 1300.
In the Special Keys example table, 0800 is entered. This means
that the system will repeat the keystrokes that you “taught” it at
8:00 every morning.
Global: GB1
The auto-scan/print routine can also be initiated by a global binary
value going ON. In the Special Keys example table, when GB1
goes ON, the routine will start. Other very useful entries that can
be input here are “NewDay” and “NewMon.” These inputs have a
pulse type nature and are ON for approximately 1 second. NewDay
is ON for 1 second at the beginning of each new day, and NewMon
is ON for 1 second at the beginning of each new month to cause the
routine to be activated.
