LCD Buttons
The 80 LCD buttons have 3 lines of text, 8 characters each. The text can be blank. The
buttons can be of 7 colors in 4 brightness levels: high, medium, low, and off. "Off" is not
quite black - you can read black text on the "off" background.
The following is an approximate representation of the 14 button colors:
Fig. 7-1: Button Colors
The best way to view this illustration is on a computer monitor. A color printer cannot
represent these colors nor can a black and white printer.
Each color is represented in Figure 7-1 as a (high-tally, low-tally) pair.
The colors of the up and down buttons are fixed. When they are off, they are white. When
they are on, they are said to be "amber." This amber is not the same as for the LCD buttons:
it is pale and almost yellow.
Firmware Upgrade
The panel's firmware is upgraded through the RS-232 connector on the back panel. See
