5.3.11 Numeric Edit Tool
The Numeric Edit Tool performs both input and output functions for analog I/O channels and for discrete
I/O channel special functions in the MAQ
®
20 data acquisition system. If an analog input channel is
assigned to the Tool, it will display the analog input channel reading. If an analog output channel is
assigned to the Tool data entered in the numeric edit box will be output to the assigned analog output
channel. Another option is to assign the Numeric Input/Output to one of the discrete I/O channel special
functions. Options are; Frequency, Pulse, Event, Duty Cycle, Period, Low Time, Width, Average, and
Maximum or Minimum special functions either on Timer 1 or Timer 2. When this assignment is made, the
Numeric Edit Tool will either display data from a special function such as frequency or counts, or can be
used as input to a special function such as PWM Generation or One-Shot Pulse. For more information on
discrete I/O special functions, refer to the MAQ
®
20 Hardware User Manual for the DIOx module.

Only the Appearance, Layout, and Behavior categories contain parameters that are useful to modify when

A Numeric Edit Tool property of interest is FormatMode under the Behavior category. Clicking on this
allows the user to change the numeric format to Binary, Engineering, Generic, Hexadecimal, Scientific, or
SimpleDouble.
Assign the analog I/O channel or discrete I/O channel special function to the Numeric Edit Tool
using the Numeric Input/ Output pull down selection box.
