User Interface
All CD-3000 Series retrofit systems are equipped with a user interface.
The user interface provides access to all programming and configuration
settings. System status is easily visible on the LCD display and LED
indicators. An infrared LED allows for printout of all system configuration
settings when used with a hand held infrared printer (Johnson System Inc.,
Part Number: JS-IP).
All of the programming is accomplished using four (4) switches. Within a few
minutes most users will find the menu structure very intuitive and easy to
navigate. All configuration settings are automatically stored into EEPROM.
LCD Display
The LCD display is capable of displaying 2 lines of 8 Characters. A backlight
automatically comes on when activity is sensed on the switches. The LCD
contrast can be easily adjusted for optimum viewing. Refer to menu item
“LCD VIEW” on page 34 for further details.
Programming Switches
The MENU UP/DOWN ( ) switches are used for navigating through the
various system configuration menu items. They also allow for programming
of other specific parameters within a selected menu. Pressing and holding
either switch will speed up the scroll rate, which can be helpful to speed up
the configuration time.
The EXECUTE switch is normally used to select/enter a menu item, advance
forward within a selected menu item, or toggle between parameters within a
selected menu item.
The ESCAPE switch is normally used to back up within a selected menu item
one step at a time, or exit the menu completely.
NOTE: The programming switches can be locked out to prevent inadvertent
configuration changes. To toggle between “LOCKED!!” and “UNLOCKED”
press and hold down the EXECUTE and then ESCAPE switches at the same
time for 4-5 seconds.
The RESET switch has two purposes. First, it allows for quick exit from a
menu item after a programming change and automatically puts the system
into normal run mode. Second, it provides a soft reboot for the systems
microcontroller.
NOTE: A detailed procedure for programming all system configuration menu
items can be found on page 20 to 34.
