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. All JS-ICON
™
Series dimmer racks are equipped with a user
interface connected to the Signal Distribution Board via a 34-pin ribbon
cable.
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
E
2
ROM.
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 30 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 15 to 30.
