Numeral Setting Section 4-8
4-8-5 Using The Thumbwheel Type of Numeral Setting (Ver.5 Direct
Connection Only)
When using the thumbwheel type of numeral setting, numerical values are input by
directly touching the incrementing/decrementing (+/–) keys.
This type of input can only be used with Ver.5 of the direct connection function.
Numerical Value Input Input numerical values by using the incrementing/decrementing (+, –) keys pro-
vided for each digit.
S
Numerical value specification
When an incrementing/decrementing (+, –) key is touched, the numeral at the
corresponding digit is incremented or decremented by one. Whenever a plus or
minus key is touched, the changed value is notified to the host. There is no need
to press the return key as is the case when using the numeric key type of numer-
al setting.

S
Changing the sign
In settings with a sign display, touching the incrementing/decrementing (+, –)
keys at the digit where the sign is displayed will change plus to minus and minus
to plus.
S
Upper/lower limit check
When using Ver.2 and later versions of the direct connection function, an upper/
lower limit check is executed when the incrementing/decrementing (+, –) keys
are pressed. If the input numerical value is outside the valid range, the data in
the numeral memory table before the key was pressed is redisplayed and not
notified to the host.
However, with thumbwheel type numeral setting, if the situation is such that with
an upper limit of 1n..n, and a lower limit of 0m..m (where n and m are the values
of each digit), n..n < m..m, it is not possible to carry digits upward or downward.
Example:
When the upper limit value is 1200 and the lower limit value is 201, if the initial
value has three digits the value can be changed within the range 201 to 999, and
if the initial value has four digits it can only be changed within the range 1000 to
1200.
