Software Configuration Program

The very first line displayed, while in this program, shows the name of the current menu

and the current address setting for the Model 26. Each Model 26 must have a unique

address and the primary Model 26 must be address number one. This address is set by the

first four switches on the OPTION SWITCH.

The Software Configuration Program is not case sensitive. Either upper or lower case

characters can be used and the results are the same. Individual parameters are selected

from menus by entering the number or letter assigned to that parameter in the left-hand

column. Pressing the E key (exit), while in the Main Menu, causes the program to exit

the Software Configuration Program completely. Pressing the E key from any other menu

returns the program to the next higher menu. After the program ends, the “SPACE” bar

must be pressed three times to reenter the program. The ENTER key is used to enter

parameters that require more than one keystroke and causes the screen to be redrawn. If

ENTER is pressed when no parameters have been entered the program simply redraws

the current screen. Once a parameter has been entered or selected it is saved in the

EEPROM of the Model 26. The Model 26 remembers the parameters set in this program,

even after it has been disconnected from all sources of power.

If an error message appears, it freezes the screen so that the user can read it. Error

messages are self-explanatory and remain on screen until “any key is pressed”. At this

point, pressing a key clears the error and causes the screen to be redrawn.

The following subsections explain each parameter in every menu. Read these subsections

carefully, the communication mode is selected here along with other parameters that

affect the entire system’s performance.

System Configuration Menu

This menu selection is found in the Main Menu. There are several different System

Configuration menus that can be displayed, depending on what communication mode has

been selected. The displayed system parameters depend on the current communication

mode of the Model 26, which is selected by the Communications Mode parameter in this

menu. Different Communication Modes require different parameters and only the

parameters that affect the selected mode are displayed. The System Configuration Menu

appears in

Figure 10.
