4.1.4 Front Panel LED Indicators
Eight LEDs on the DMD15/DMD15L Front Panel (Refer to Table 4-3) indicate the status of
DMD15/DMD15L operation. The LED colors maintain a consistent meaning. Green signifies that
the indication is appropriate for normal operation, Yellow means that there is a condition not
proper for normal operation, and Red indicates a fault condition that will result in lost
communications.

4.2 Parameter Setup
The four Cursor Control Arrow Keys are used to navigate the menu tree and select the parameter
to be set. After arriving at a parameter that needs to be modified, depress <ENTER>. The first
space of the modifiable parameter highlights (blinks) and is ready for a new parameter to be
entered. After entering the new parameter using the keypad (Refer to Figure 4-2), depress
<ENTER> to lock in the new parameter. If a change needs to be made prior to pressing
<ENTER>, depress <CLEAR> and the display defaults back to the original parameter. Depress
<ENTER> again and re-enter the new parameters followed by <ENTER>.
Following a valid input, the DMD15/DMD15L will place the new setting into the nonvolatile
EEPROM making it available immediately and available the next time the unit is powered-up.’
