6-4-2 Notification of numeral setting input and touch switch status
The following describes the commands for notifying the host when numeral setting
is performed (i.e., when the contents of a numeral memory table are changed by
pressing a touch switch) or when a touch switch is pressed, when operating the
NT20S.
When a numerical value is input by numeral setting, the NT20S sends a Number
Input Notify Command to the host. The command sent differs depending on
whether a 4-digit or 8-digit number is input.
When a touch switch is pressed, the NT20S sends a Touch Switch Number Output
Command or Touch Switch Bit Output Command to the host. The command sent
depends on the set screen attributes.
