For reliable noise free communication, use a pair of twisted wires inside screened cable. The wire should have less than 100
ohms / km nominal DC resistance (Typically 24 AWG or thicker). Connect the terminating resistor (Typically 100 to 150 ohm)
at one end to improve noise immunity.

described below.
Numeric Parameters
This type of parameter has 2 fields; & as shown in the figure. The value for this type of parameter is set Name Field Value Field
using a Numeric keypad that pops up upon touching the for the parameter. The value can be edited using numeric Value Field
keys & other functional keys as shown in the figure. Use ENT key for storing the new value or use ESC key to revert without
changes. Touching ENT or ESC key, the keypad automatically collapses.
Name Field Value Field
Note that if the modified value falls outside the Minimum or Maximum limits specified for the
parameter value then the parameter retains the old value.
Selected Option
Unselected Options
String Option Parameters
This type of parameter has 2 or more fixed options to choose from. All the options are shown in rectangular boxes with
appropriate texts as shown in the figure. Only one of the several options can be selected. The selected option box is shown in
bright ( ) color, while all other unselected options are shown in dark ( ) color. For selecting the desired option. just touch
the box and wait for a while until the color changes from unselected to selected.
