Video Display Terminal Programming Procedure
Introduction
The programming procedure is menu driven.

A list of selections are presented for consideration
which differ in content and required response.
Each selection, when responded to, either causes a
further breakdown of selections to be presented or
causes a particular COS programming action to
take place.
This menu system prompts the programmer for the
required response and, where appropriate, will
repeat prompts to allow programming of more than
one device without having to make another menu
selection.
All of the menus operate in the same manner.
They differ in only the required response.
Each prompt requires a response followed by a
Carriage Return (RETURN). The responses
usually consist of a one or two-digit number or a
string of numbers or alpha-numeric characters
when programming names and messages.
Separate successive entries in a string by a space
or a comma; however, do not end a string of entries
with a comma. If you do, the system will reject the
string.
General Information

Procedure
Determine the system programming parameters,
and record them for future reference.
Turn on the AC power to the system and the VDT.
Press the RETURN (ENTER) key. The system ’
enters an approximate 20 second timeout cycle.
Step 4 must be performed within this timeout
period or the programming sequence will be
aborted.
Type the password: I +# 7 4 6 t, and press
RETURN (ENTER). The VDT will display the
main programming menu. The system enters an
approximate 3 minute timeout cycle. A selection
or response must be entered within this timeout
period, otherwise; the programming sequence is
aborted.
,
Execute the programming procedures by
responding to the prompts listed in first the main
menu and then in subsequent menus.
