Changing and saving Setup parameters
To select a Setup parameter and assign a value to it, follow these steps:
1. Move the highlighted field over the parameter desired by touching the UP or
DOWN touch keys (to the left of the Parameter List in the Direction Action
Area), or by pressing the up or down arrow keys on the optional keyboard.
2. Scroll through the range of the parameter’s values until the desired value
appears by touching the SELECT VALUE touch key (or by pressing Return/
Enter on the optional keyboard).
As soon as a parameter’s value appears, the setting takes effect. The only
exception is setting the Display Activity parameter to off, which takes effect
upon exiting the Setup screen.
3. Select and change the settings of all other parameters that you want to adjust.
For details on each parameter, see “Parameters”, starting on page 30
4. When you are satisfied with the parameter settings, you can save them in
nonvolatile Setup memory by touching the SAVE touch key in the Direct
Action Area (or pressing Shift/S on an optional keyboard).
After the Setup parameters are saved, they remain selected even after power
is turned off. The next time power is turned on, the terminal will be
programmed with the previously saved parameter values.
The only exception is the Local/Remote parameter value, which cannot be
saved in memory. The Local/Remote parameter is always set to Remote at
power-up so the host can communicate with the terminal when it is turned
on.
A soft reset is executed at power-up or when you touch the RESET touch key on
the Setup screen. On soft reset, the terminal recalls the Setup parameter values
saved in the last Setup screen session.
Important
See “How to test the touch control screen” in this chapter for information about Setup
parameter values.
