2-4. Operating Techniques Using Display and Keyboard.
The display and keyboard form the communications link between the operator and the TD-1337(V)/G. The
operator requests or enters data by pressing keys on the keyboard. The display, in turn, responds by
displaying messages that are associated with the operator actions. The types of messages that can be
displayed are described in paragraph 2-5. In addition to the message displays, there are other operating
features that the operator should be aware of in performing the operating and configuration routines. These
features are described below.
a. Display Blanking. Display automatically blanks when operator does not press a key within 30 seconds
of last key pressed.
b. Reactivate Display. Operator can press any key to reactivate display. Last message that was dis-
played prior to blanking reappears when operator presses a key.
c. Display Blanked, While display is blanked, operator cannot enter data or change a routine until
display is reactivated.
d. ENTR Key. When entering data in a routine, the TD-1337(V)/G recognizes an operator entry when
one or more numbered keys (O through 9) are pressed and the ENTR key is pressed. A message may
request one operator entry or a message may request two or more entries (called multiple-entry messages).
When the last entry required for a given message is made (ENTR key is pressed), the next message
in the routine is automatically displayed.
e. CLR Key. CLR key allows operator to change numbers entered by keyboard before the ENTR
key is pressed, When the CLR key is pressed, all numbers displayed at prompt are erased and the
proper entry can be made without further corrective action.
f. Invalid Data Entry. When operator enters invalid data, the "ILLEGAL ENTRY, REENTER" message
is displayed. Operator presses CLR key and the message displayed at the time of the invalid entry reappears,
At this time, operator can enter the proper data.
Example: Message display requests that operator select and enter a "1", "2", or a "3". Operator enters
a "4" and the `(ILLEGAL ENTRY, REENTER" message is displayed. Operator presses CLR key
and message that requests operator to select and enter a "1", "2", or "3" reappears.
g. Prompt. Messages that require an operator entry have a prompt displayed as shown below. When
the operator enters the required data (using numbered keys), the entered data appears to the right of
the prompt, In multiple-entry messages, the prompt moves to the next valid entry point as each entry
is completed (after ENTR key is pressed).
Example: Message indicates operator has made entries for ports 1 through 4 and data for port 5 is requested.
When data is entered for port 5 (number keys and then ENTR key pressed), the prompt will
move to port 6.
