FUNCTION / NAVIGATION
The Scheduler-Timer has an LCD display with 2 lines of 16 characters, a diagnostic LED, 7 buttons,
a polarized power connector and a DB-9 serial port. The 7 buttons provide easy navigation through
the menus on the LCD display and are described as follows:
MENU:
Provides access to the main menu from the Idle Screen. It will also return the display to
the previous menu or Idle Screen from any sub-menu by exiting the selection without saving the
configuration data.
ENTER:
Enters a menu item or saves a selected setting. It provides movement through a selected
menu item's editable fields and executes commands.
UP and DOWN:
Provide movement through the menus and toggles through characters when
editing a selection.
RIGHT and LEFT:
Provide movement across the display.
FUNCTION:
Toggles the backlight on the LCD display.
Diagnostic LED:
The diagnostic LED operates just like the LED of a Computer Interface Module
(CIM). In CIM Mode the Scheduler-Timer exchanges UPB messages between the powerline and
connected computer or controller via the RS-232 / DB9 cable included. The indicator on the UCS
will glow AMBER when powered, flash RED when UPB messages are seen on the power line and
flash GREEN when a UPB message is transmitted from the Scheduler-Timer.
DB9 Port:
T
onnect the provided
serial cable (standard DB9, male to female) between the UCS and a computer's RS-232 port. The
DB9 port may also be used to upgrade the firmware in the UCS, if needed (see “Updating the
Controller Scheduler-Timer” section at the end of this User Guide). Note, if the computer does not
have a RS-232 port, a USB to serial adapter will be needed.
