Section 4-8

Numeric Key Type

When a numerical value is input using touch switches to which numeric key func-
tions have been allocated, the input numerical value is displayed on the screen.
On pressing the return key after completing input, the input numerical value is writ-
ten to the numeral memory table and notified to the host.
If there is more than one numeral setting input field, the field in which the input is to
be made can also be selected with the numeric keys.
In order to perform numeric key input, it is necessary not only to create a numeral
setting input field on the screen, but also to create the numeric keys to be used for
input (see page 146).

NT600S

Thumbwheel Type (Ver.5 Direct Connection Only)

When using an NT600S-ST121/ST211-EV

with Ver.5 direct connection, numeri-

cal values are input directly at the numeral setting input field using touch switches
that increment or decrement each of the digits in the display when pressed. Each
time the displayed numerical value is changed, the new displayed value is written
to the numeral memory table and simultaneously notified to the host.
This means that, when using the Thumbwheel type of numeral setting, all that is
required to input numerical values is to create the numeral setting input field on the
screen.

Pressing the [--] key
decrements the digit by one.

Pressing the [+] key
increments the digit by one.
