Sedona LCD Display

The display can be used as an operating panel to display and manage the algorithm of the iSMA-B-AAC20 controller or to view and manage system settings.

The built-in display is a monochrome display with backlighting. It can display up to 20 characters per line and up to 7 rows on one screen. Up to 16 lines can be displayed in a single screen, and scrolling is available with up/down arrows (one line at a time) or with the keys F1/F2 (scrolling entire screens).

Note: The display supports only the basic ASCII characters.

There are 6 dedicated keys to operate the display:

  • Esc: exit key;
  • Enter: select, move the cursor to the right;
  • Arrow up: add/subtract, menu navigation;
  • Arrow down: add/subtract, menu navigation;
  • F1: function key;
  • F2: function key.

LCD System Menu

The iSMA-B-AAC20 controller with the display has an option to log in to the system menu without a necessity to add any additional components to the Sedona environment.

Log in/log out system menu process:

  • Press and hold the F1 key (displays "Enter Password");
  • Use the arrow keys (the change of the digital value by 1) and move through the coming fields (using the Enter key), enter the password to the system (a 4 digit number, 1000 is a default value);
  • Approve the input password by pressing and holding the Enter key;
  • Cancelling the login process and exiting from the system menu – press and hold the Esc key.

The system menu consists of the following components:

  • Info: provides information about your device and hardware resources;
  • Local I/O: contains information about the current values of inputs/outputs of the physical devices and their configuration options;
  • Network Config: changes the IP address of the device and the port and address of the Modbus TCP/IP protocol;
  • Change password: changes the password to log in to the system menu and to the website (editing the Device Password slot in the Plat component);
  • Reboot: restarts the device (required when you change the IP address).
