Enter Key (EN TR)
The Enter key enters the data that was keyed via the
manual keyboard into the system as a data entry.
Clear Key
The Clear key clears an unaccepted data entry from the
area station, extinguishes the Error lamp, releases the
media (card or badge), and clears the display. The operator
presses the Clear key to clear display before entering data
through the keyboard.
Next Guidance Key
The Next Guidance key signals that the last data entry
of a multiple data entry transaction step ("M" transaction
step) has been entered and calls for the next guidance step.
This key is also used to relight the original guidance light
on a data entry step after an error light has been turned on,
except on the first data entry of a multiple step transaction.
Monitor Key
The Monitor key is located on the lower left cover. This
key is a key-lock switch that allows the key holder to add
an approval to a given transaction. Key OFF sends a 0 as
the first digit of the data entry; key ON sends a 1 as the
first digit of the data entry.
Manual Entry
The 12-key numeric keyboard located at the lower front
provides for the entry of decimal numerics 0 through 9,
-, and =. As each key is pressed, the number or special
character is displayed to the operator for verification. Up
to six positions are displayed for any one data entry. After
verification, an Enter key is pressed to transmit the data to
the 2715 TCU at approximately 100 characters per second.
Additional data entries from the keyboard may be chained
into one transaction under 2715 user-table control (trans
action list steps).
Visual Display
A six-position visual readout is located on the lower front
cover. As many as six digits of numeric data can be verified
in the visual display before transmission. Valid characters
are 0 through 9, blank, -, and =. The time of day is displayed
when manual entry is not in use. The time-of-day display is
valid if the On Line light is on. The time may not have been
updated if the On Line light is off.
Operator Guidance Panel
The operator guidance panel (Figure 11) has three sections-
transaction selection area; operator guidance nomenclature;
and operational indicators.

Operator Panel
Transaction Selection Area
Adjacent to each transaction key is an area in which the
customer may provide nomenclature in language appropriate
to his industry or application. This area describes a particular
transaction that is handled if the adjacent button is pushed.
User options at the system controller can vary key assign
ments between 279 Fs.
Operator Guidance Nomenclature
This section of the operator guidance panel consists of a
4 by 8 light matrix in which one rectangle of the 32 is
illuminated as a result of decoding the low-order five bits of
the guidance character. The light panel describes in the
customer's own words actions to be taken by the operator—
that is, the type of badge, card, or other significant informa
tion relative to the expected data entry. Of the 32 guidance
characters, 31 are available to the customer. The 32nd one
is dedicated to "select transaction" , which notifies the op
erator that a new transaction may be selected. (The Release
transaction pushbutton must be pressed before a new trans
action can be selected.)
The programmer defines which guidance lights are turned
on for a transaction when he defines the transaction list
| (TRLIST) macro. See Systems Reference Library manuals,
